MANAGEMENT OF LABORATORY SCHOOLS BY THE STATE UNIVERSITY OF THE FORMER EDUCATIONAL PERSONNEL EDUCATION INSTITUTE (LPTK / IKIP) (Studies in Legal Perspective)
Authors: Endang Endang
Published: July 2021

The aim of this research is to look into the legal perspective on laboratory management by the State University in Indonesia, the former The Educational Personnel Education Institute (LPTK / IKIP). The site that becomes the object of this study is “Universitas Pendidikan Indonesia” (UPI, Bandung) which organizes a Laboratory School in the form of a formal school which includes primary and secondary education. UPI laboratory school strives to provide educational services to students according to their expectations (vision and mission of the laboratory school), becoming a forum for the development of various professional teachers and educational practices. In addition, schools can also become models for creative and innovative learning practices by professional teacher candidates in collaboration with the relevant LPTK (Educational Institutions) and Provincial, Regency / City Education Offices. The results of the study concluded that the authority to manage formal education units - at the levels of PAUD / TK, SD, SMP, and SMA, rests with the regency / city government and the provincial government or the community as the organizing institution, not the authority of higher education. If the UPI Laboratory School is a formal school, then UPI must establish an organizing legal entity.

Published: July 2021

Community empowerment is how to make people have the ability and independence in utilizing the existing potentials. In Banding Agung Village, Pesawaran Lampung, the abundant water resources available can be used for freshwater aquaculture activity as a strategy for empowering the community. The study aims to  explore the strategies of community empowerment based on freshwater aquaculture activity, and  to find out  the  factors inhibiting  the community empowerment. This is a kind of descriptive qualitative research using case study framework. The data were collected through in-depth interviews, observation, and documentation and analyzed qualitatively employing data reduction, data display, and data verification. The findings indicated that some strategies have been implemented in empowering the community based on the freshwater aquaculture activity, consisting of building the community awareness on the importance of  fish farming group (pokdakan), building institutional capacity through education, training and workshop of fish farming management, and putting group members’ knowledge and skill into practice.  In the implementation of the strategies, some obstacles were found as the factors inhibiting the community empowerment, namely lack of community participation, lack of  knowledge and capital, minimum assistance and counseling, and less involvement of the village government. The study recommends several alternative actions for a better implementation of the community empowerment.
Application of mathematical modeling methods to determine the effect of soil on natural vibration frequencies of pipelines
Authors: Chanchina V. E. , Gaponenko S. O. , Kondratyev A. E. , Fedotova A. O. , Mustafina G. R.
Published: July 2021

When a pipeline is subjected to an external influence that can affect the frequency of its natural vibrations, the parameters of its natural vibrations change, which increases the measurement error, and often simply distorts the results of vibration control. For pipelines, such an impact may be the influence of the soil when pipelines are laid without a channel. Different types of soil affect the change in the natural vibration frequency of the pipeline in different ways.The purpose of the article is to analyze the influence of various types of soils on the parameters of natural vibrations of the pipeline. The aim of the study was to theoretically confirm the dependence of the change in the frequency of vibration of the pipeline under the influence of soil.A modal analysis of natural oscillations of 5 polyethylene pipelines was performed. As initial data, it is assumed that the design pipeline is laid in a trench with inclined walls, with the slope laid on a flat base at a depth of 2.5 m. The calculations were performed in the ANSYS finite element analysis software package. In order to build a mathematical model, the degree of soil impact on pipelines is determined by studying the vertical and lateral pressure of the soil on the above pipelines, and the natural vibrations of pipelines are analyzed.The results of the modal analysis for polyethylene pipes with a laying scheme with inclined walls and different soils (gravel sands, coarse and medium-sized; heavy clays) are presented. The soils were chosen that are the most common on the territory of Russia.Thus, the obtained dependence of the degree of influence of different soil on the natural frequencies of pipelines significantly increases the reliability of vibration diagnostics of buried communications, can facilitate the work on its organization and allow determining long-term forecasts of pipeline operation.
A doutrina de combate da expansão imperial na cronística portuguesa da Terra de Santa Cruz
Authors: Freire Wellington José Gomes
Published: July 2021

O presente artigo pretende se deter sobre a representação dos modos de condução da guerra da expansão imperial portuguesa quinhentista contida nas narrativas cronisticas que tratam da presença militar lusitana na América portuguesa. Pleiteia-se que os métodos de combate descritos nos textos sugerem que a revolução nos assuntos militares, termo que designa na bibliografia especializada o processo de modernização dos exércitos europeus modernos, não fincou raízes em solo lusitano quatrocentista e quinhentista. Os guerreiros e conquistadores que se assenhorearam de uma vasta porção do globo utilizaram predominantemente de táticas de incursão de infantaria desordenada ao estilo de razias. O estudo se baseou em um corpus constituído por cronistas quatrocentistas e quinhentistas: Gomes Eanes de Zurara; Rui de Pina; João de Barros; Lopes de Castanheda; Gaspar Correia; Gabriel Soares de Souza e Frei Vicente de Salvador.
Insularidade e identidade em Onésimo Teotónio Almeida: da cultura à literatura
Authors: Martins Josê Cândido De Oliveira
Published: July 2021

A ilha e a condição da insularidade, face ao continente, constituíram-se, frequentemente, como continuado pretexto afectivo e sobretudo intelectual para questionação do complexo tema da identidade cultural (regional, nacional ou supra-nacional), tema polémico e complexo. Isso é particularmente visível na escrita, sobretudo ensaística, mas também literária, do escritor português Onésimo Teotónio de Almeida. Em várias das suas publicações, ao longo de algumas décadas – desde os ensaios aos textos criativos – o discurso reflexivo deste autor visa uma persistente indagação identitária, que articula o local ou regional com o nacional e até o universal, abarcando os sistemas da cultura e da literatura.

Great molecular variation within the species Phytoseius finitimus (Acari: Phytoseiidae): implications for diagnosis decision within the mite family Phytoseiidae
Authors: Tixier Marie-Stéphane , Dos Santos Vicente Victor , Douin Martial , Duso Carlo , Kreiter Serge
Published: July 2021

Molecular markers are increasingly used for species identification and new taxa description. However, rules to determine frontiers between populations and species are not clear depending on taxa considered. For mites, few studies deal with molecular diagnoses, making rules for associated decision difficult. The present study focuses on a species of the predatory mite family Phytoseiidae (Phytoseius finitimus), considered for biological control of mites and small insect pests in fruit orchards and vineyards in the Mediterranean basin. This paper aims to elucidate the causes of great molecular variations and questions the occurrence of cryptic species. Molecular (12S rRNA, CytB mtDNA, ITSS) and morphological analyses were performed on four populations collected in Corsica and Italy in crops (vine and kiwi) and in an uncultivated environment (Viburnum lantana). Different methods for identifying species have been used (tree approaches, distances and ABGD algorithms). A reference database of distances within and between Phytoseiidae species has been elaborated to inform the present question and to assist with further diagnosis within Acari. Mitochondrial DNA analyses show that specimens from V. lantana were well separated from the three other populations with high genetic distances, suggesting the existence of a cryptic species. Molecular ITSS analyses coupled with morphological features show however that the four populations seem to belong to the same species. The great mitochondrial polymorphism is discussed in regards to: (i) genetic distances reported for Phytoseiidae species and (ii) potential biological differences between populations (cultivated versus uncultivated areas). This study clearly emphasizes the necessity of integrative taxonomy approaches for diagnosis decisions. Furthermore, based on the polymorphism herein detected, maximal intraspecific distances are proposed (9, 23 and 2.8 % for 12S rRNA, CytB mtDNA and ITSS) for diagnosis decisions within Phytoseiidae. Further statistical analyses are however clearly required to determine statistical error for general and reliable decision making.

Life table of the red spider mite Tetranychus bastosi (Acari: Tetranychidae) on different host plants
Authors: de Lima R. Pereira , Bezerra Marcello M. , de Moraes Gilberto J. , Furtado Imeuda
Published: July 2021

Tetranychus bastosi Tuttle, Baker and Sales was described from Ceará state, northeastern Brazil. It has so far been reported from 25 plant species, among which cassava (Manihot esculenta Crants), common bean (Phaseolus vulgaris L.) and papaya (Carica papaya L). Although there is no information about its impact on crop yield, high population levels have been observed on some crops, leading to suppose that damage might occur in some occasions. In this study, fertility life table parameters were calculated for T. bastosi on cassava, common bean and papaya at 25 ± 2 °C, 70 ± 5% RH and photoperiod of 12/12 h. The best performance of T. bastosi occurred on C. papaya and P. vulgaris, on which the intrinsic rate of population increase reached 0.184 and 0.183 female/female/day, respectively. These results agree with the most common occurrence of this mite on papaya and on common bean than on cassava.

In this study, we evaluated the impact of different fire regimes (early, mid-season, or late fire) on soil mite abundance and diversity in three study sites (Salty marigot, Plateau and North piste) of the Lamto shrub savannah at 160 km northwest of Abidjan, Côte d’Ivoire. On each site, three adjacent plots of 100 m x 50 m were delimited, to which a given fire regime was applied. At each site, soil cores were taken at 0-10 cm soil depth three days before the fire application, the day after and one month after the fire (10 soil cores x 3 sampling periods x 3 fire regimes or plots x 3 sites = 270 soil cores). Soil mites were then extracted from these cores. 108 soil cores were sampled at two upper layers (0-5 and 5-10 cm) for estimation of the bulk density and water content. After data analysis, four groups of mite were observed (Actinedida, Gamasida, Oribatida and Acaridida). Gamasida and Oribatida were dominant groups (early fire: Gamasida 35%, Oribatida 55%; mid-season fire: Gamasida 16%, Oribatida 70%; late fire: Gamasida 16%, Oribatida 74%). In total, 70 species were observed, with 29, 44 and 31 species recorded respectively during the early, mid-season and late fires. Mite density and species richness varied significantly along the three fire regimes and decreased substantially after fire application. Except for the mid-season fire, Simpson index from all mites differed significantly across sampling periods. Lower Oribatida represented 25% of the total Oribatida. Whatever the fire regimes, brachypyline Oribatida abundance increased the day after fire application. Overall, fire intensity reduced drastically soil mite abundance and diversity.

Mesovoid shallow substratum as a biodiversity hotspot for conservation priorities: analysis of oribatid mite (Acari: Oribatida) fauna
Authors: Nae Ioana , Băncilă Raluca Ioana
Published: July 2021

The mesovoid shallow substratum (MSS) is a unique habitat that shelters and serves as a microrefuge for epigean, endogean and hypogean invertebrate species. Understanding the MSS community′s spatio-temporal structure and species diversity patterns in relation to the environmental parameters plays a crucial role in conservation. In this study we investigated: i) the diversity and community structure of oribatid mites from edaphic habitat, superficial MSS (i.e., the upper layer of MSS) and deep MSS (i.e., lower layer of MSS) in an alpine region of Southern Carpathians, Romania, and ii) the relationships between the oribatid mite communities and the environmental variables, such as temperature and humidity. The composition and the structure of oribatid communities differed along the three habitats indicating possible habitat specialization. The structure of the oribatid community was influenced by temperature and humidity. The rich and mixed oribatid communities in the MSS and the oribatid communities' response to surface and subsurface environmental variables suggest that the MSS may offer a micro-refuge for edaphic species when the conditions in the surface habitats become too harsh. Thus, we suggest that MSS should be prioritized for conservation because it may be the key component in maintaining biodiversity.

Two Eocene species of peacock mites (Acari: Tetranychoidea: Tuckerellidae)
Authors: Sidorchuk Ekaterina A. , Khaustov Alexander A.
Published: July 2021

Tuckerellidae are suctorial plant feeders with a wide host range, exploiting both aboveground and underground plant parts. A new species, Tuckerella weiterschani n. sp., is described from Eocene (ca. 40 mya) Baltic amber, and Tuckerella fossilibus Khaustov, Sergeyenko and Perkovsky, 2014 from Eocene Rovno (Ukrainian) amber is redescribed, each based on single holotype specimens. The two mites are morphologically distinct, with most striking differences concerning posterior, H-row of idiosomal setae. Tuckerella fossilibus has unusually large, obovate setae h1, while the other, setae in H-row are robust and fagellate with three different lengths. The new species, T. weiterschani, has small, narrowly lanceolate setae h1, while flagellate h2–h8 are fine, filiform and similar in length. Setae h1–h8 in the holotype of T. weiterschani are held erect and directed forward over the mite’s body, in a position reminiscent of the apparently defensive posture displayed by recent Tuckerella species. Tarsal setations of the two fossils and comparison with those of the recent Tuckerellidae advances discussion on the evolutionary significance of setal variation in acariform mites.
Biology and life-table of Typhlodromus (Anthoseius) athenas (Acari: Phytoseiidae) fed with the Old World Date Mite, Oligonychus afrasiaticus (Acari: Tetranychidae)
Authors: Ben Chaaban Samah , Chermiti Brahim , Kreiter Serge
Published: July 2021

The old world date mite Oligonychus afrasiaticus is an important spider mite pest of the date palms Phoenix dactylifera L. mostly in North Africa and the Middle East. A population of the predaceous mite Typhlodromus (Anthoseius) athenas has been recently found in Tunisia in association with a decrease of O. afrasiaticus densities. The objective of this paper was to assess the development and reproduction abilities of T. ( A.) athenas on O. afrasiaticus under laboratory conditions at two temperatures: 27 and 32 °C. The results obtained show that females of T. (A.) athenas develop in 5 days at 27 °C and 4.1 days at 32 °C. The mean fecundity of T. (A.) athenas was 32.1 and 23.2 eggs per female at 27 and 32 °C, respectively. Life table parameters were stimated: the net reproductive rate (Ro) 27.9 and 17.9 eggs/female, the intrinsic rate of increase (rm) 0.322 and 0,344 female/female/day and the mean generation time (T) 10.3 and 8.4 days at 27 and 32 °C, respectively. At both temperatures tested, T. (A.) athenas intrinsic rate of increase was greater than that of O. afrasiaticus (rm = 0.213 at 32 °C,against rm = 0.166 day1 at 27 °C). Typhlodromus (A.) athenas would be able to develop at a wide range of temperatures feeding on O. afrasiaticus and seems to be able to potentially control it.

Authors: Horn Tamara Bianca , Granich Juliana , Horn Körbes Júlia , Liberato Da Silva Guilherme , Juarez Ferla Noeli
Published: July 2021

This study is based on results from a large project on the mite diversity in commercial laying hen systems in Brazil. It aims to identify potential biocontrol agents amongst mites present in poultry farms, with a focus on one feather mite pest Megninia ginglymura. A secondary goal is to provide an operational identification tool to help the development of biological control in poultry farms. Sampling was conducted from August 2013 to August 2014, with 43 sampling events, in three different laying hen management systems. We used traps, laying hen feathers, and abandoned wild bird nests to collect the mites. A total of 38,862 mites belonging to 23 families and 39 species were found, including 17 species exclusively found in traps, six in wild bird nests, and one in feathers. The most abundant and frequent ectoparasitic species was M. ginglymura (76.3%; observed in all management systems). Amongst other mites, Tydeidae showed the highest richness with five species (Brachytydeus argentinensis (Baker, 1970), Brachytydeus australensis (Baker, 1970), Brachytydeus obnoxia (Kuznetzov and Zapletina, 1972), Brachytydeus oregonensis (Baker, 1970), and Brachytydeus tuttlei (Baker, 1965)), followed by Cheyletidae with four species (Chelacheles bipanus Summers and Price, 1970, Cheyletus eruditus (Schrank, 1781), Cheyletus malaccensis (Oudemans, 1903), and Cheletomimus (Hemicheyletia) wellsi (Baker, 1949)). Potential predatory species for biological control were C. malaccensis (9.4%), Typhlodromus transvaalensis (Nesbitt, 1951) (0.8%), Blattisocius keegani (Fox, 1947) (0.7%), and Blattisocius dentriticus (Berlese, 1918) (0.4%). A dichotomous key is provided to identify 48 species dwelling in Brazilian layer farms.
Susceptibility to acaricides and detoxifying enzyme activities in the red spider mite, Oligonychus coffeae Nietner (Acari: Tetranychidae)
Authors: Roy Somnath , Prasad Anjali Km. , Handique Gautam , Deka Bipanchi
Published: July 2021

Susceptibility of red spider mite, Oligonychus coffeae Nietner (Acari: Tetranychidae), collected from conventionally-managed (synthetic acaricide usage) versus an organicallymanaged (no acaricide usage) tea plantations in Assam, India, to five synthetic acaricides was determined in laboratory bioassays. Activity of three principal detoxifying enzymes of these mite populations was also assayed. The median lethal concentrations (LC50) of ethion, dicofol, propargite, fenpropathrin, and fenazaquin were 1049.75, 599.21, 232.03, 11.44, and 6.75 ppm, respectively. Field rates of these acaricides were compared with 95% lethal concentration (LC95 in ppm) values, and a decrease in the susceptibility of the test population to ethion, propargite, dicofol and fenpropathrin was observed. There was no change for fenazaquin which was effective at lower doses than the recommended dose. Of all the acaricides tested, fenazaquin was the most toxic and ethion was the least toxic. General esterases (GEs), glutathione- S-transferase (GST), and cytochrome P450 monooxygenases exhibited a higher activity in mite population from the conventionallymanaged tea plantation as compared with the activity in mites from the organicallymanaged tea plantation. These findings may be helpful in the selection of acaricides and in developing resistance management strategies for an effective management program for this major tea pest.
Microarthropods in australian sugarcane soils: A survey with emphasis on the Mesostigmata as potential regulators of nematode populations
Authors: Walter David E. , Stirling G.R.
Published: July 2021

Sugarcane is attacked by a suite of nematode pests, but little is known of the mites and other soil microarthropods that feed on them. To address this deficit, we undertook a survey of the soil microarthropod fauna in 60 sugarcane fields in Queensland, Australia. The results showed that oribatid mites and springtails dominated the upper 10 cm of sugarcane mineral soils. Laboratory observations demonstrated avid nematophagy in Galumnidae (Galumna sp., Pergalumna sp.), Scheloribatidae (Scheloribates sp.), and one unidentified Isotomidae (Collembola). Mesostigmata, a group of mites with many known nematophages, were never very abundant. Most of the taxa identified were previously known from Australia, but Protogamasellus sigillophorus Mineiro, Lindquist and De Moraes is reported for the first time and was reared through several generations on nematodes. In addition, we reared ten other cane field mesostigmatans on nematodes: Antennolaelaps sp., Asca garmani, Asca major, Cheiroseius sp., Cosmolaelaps sp., Gaeolaelaps sp., Gamasellodes bicolor, Gamasiphis sp., Holaspulus tenuipes, Protogamasellus mica. Because Mesostigmata were present at higher population densities in mineral soil where a mulch layer was retained after harvest, we assessed the effect of mulching in two sugarcane fields. Mulching did not result in significant differences in total microarthropods in the upper 5 cm of mineral soil. However, the mulch contained large numbers of free-living nematodes and 10% of the microarthropods were nematophagous mites. Results from a pot experiment also suggested that differences in soil properties affect nematophagous mite communities. More microarthropods and greater numbers of Mesostigmata were recovered from a well-structured clay loam soil than a sandy loam soil, and populations were highest in surface soils with high carbon contents and high levels of microbial activity.
Survey of European mites from the suborder Uropodina: II. Morphology, geographical distribution, biology, and ecology of Trematurella elegans (Kramer, 1882)

Published: July 2021

The major aim of this article was to supplement the existing descriptions of the morphology, biology, ecology, and geographical distribution of Trematurella elegans (Kramer, 1882) (Acari: Mesostigmata) with a bit of new information about the species. The data available in the literature on this species is scant. The available taxonomic descriptions are based on schematic and very rough drawings. The authors of this article conducted a research study that will shed more light on this species. The study is based on a large set of data (21,741 samples), which have been collected for over 50 years in the area of Poland and a few other European countries. The description of the morphology of the species is based on materials obtained from a scanning electron microscope, and the description of the distribution of the species on the basis of data obtained from the GIS system, which allows the precise localisation of samples to be determined. Finally, the authors have also tried to ascertain the habitat preferences of T. elegans, analyzing the phenology and influence of the altitude on the distribution of the species. This study is probably the first attempt to establish the effects of the Pleistocene glaciations on the current distribution of T. elegans in Poland and the whole area of Europe.

Published: July 2021

The common tick Ixodes ricinus is the main vector of Borrelia burgdorferi sensu lato, Anaplasma phagocytophilum and Babesia microti in Europe. The aim of this study was to estimate the potential risk of exposure to common tick-borne diseases in the recreational areas of the Kraków-Częstochowa Upland, Poland with particular emphasis on the city of Częstochowa. The DNA from 459 I. ricinus ticks was used to detect B. burgdorferi s. l., A. phagocytophilum and B. microti by PCR and nested PCR methods. Generally, infectious agents were found in 26.3% of all the examined ticks: B. microti was found in 23.3%, and A. phagocytophilum in 2.4% of the ticks. The protozoan was found mainly in females and nymphs, while A. phagocytophilum was detected mainly in adults. The co-existence of B. microti and A. phagocytophilum was found in 2.1% of the examined ticks. The presence of B. burgdorferi s. l. was not revealed in the examined material. The conducted studies demonstrate the high potential risk of exposure of tourists and pilgrims to B. microti, and a low risk of exposure to A. phagocytophilum and B. burgdorferi s.l. in the examined areas of the Kraków-Częstochowa Upland. Furthermore, the possible co-existence of A. phagocytophilum and B. microti in 3 individual ticks means that infection by multiple infectious agents is possible. The obtained results highlight the need to conduct further research on tick-borne pathogens in this region of Poland.
New records, a completed list and identification key of mites (Acari) associated with the stable fly, Stomoxys calcitrans (L.) (Diptera: Muscidae)
Authors: Kontschán Jenő , Hornok Sándor
Published: July 2021

The stable fly, Stomoxys calcitrans (L.) is a blood-sucking muscid fly species, with a worldwide distribution and high veterinary-medical importance. In this study, four mite species were collected from stable flies in Hungary. One mite species (Trichotrombidium muscarum (Riley, 1878)) from the family Microtrombidiidae was parasitic on the flies, collected in high numbers from their bodies. The other three species were found in small numbers on the flies, which they use only for transportation. The latter included the phoretic female of Pediculaster mesembrinae (Canestrini, 1881) (Acari: Siteroptidae), the phoretic deutonymph of the Halolaelaps sexclavatus (Oudemans, 1902) (Acari: Halolaelapidae) and Macrocheles subbadius (Berlese, 1904) (Acari: Macrochelidae). This is the first record of an association between the stable fly and two mite species (Trichotrombidium muscarum and Halolaelaps sexclavatus). A new, completed list and identification key of known stable fly associated mites are also provided.

Published: July 2021

The life table parameters of Tetranychus urticae were evaluated on 7 eggplant cultivars namely, Anamur, Aydin Siyahi, Balikesir 76, Kemer, Pala 49, Topan 374, Yalova Topan, in controlled laboratory conditions in day ight for 16 hours 27 +/- 1 °C temperature, 65% relative humidity. Assays were conducted on eggplant leaflets in Petri dishes. There was a significant difference in the durations of egg and juvenile development of T. urticae. However the survival rates of T. urticae were not significantly different on the tested eggplant cultivars. The values of the natural rate of increase, rm, (0.218-0.269), net reproduction rate, R0, (26.74-45.51) and the mean generation time, T, (13.31-15.45) significantly differed among eggplant cultivars. Notably, the shortest development duration as indicated by the lowest rm and R0 values were observed on Pala 49 followed by Anamur and Balikesir 76 cultivars.

Published: July 2021

Urban brownfields are ecologically valuable ecosystems that have been and are under various anthropogenic influences. Because brownfields are subject to rapid development in urban areas, their biological communities, including soil mesofauna, are overlooked and seldom researched, even though they could provide valuable insight into the ecological functioning of these areas. This exploratory study describes the community characteristics of oribatid mite fauna of 12 brownfields in Tallinn, Estonia, and analyzes the potential of oribatid mites as bioindicators of brownfield successional stage. This study provides the first faunistic list of oribatid mites from the brownfields of Tallinn. No significant changes in species abundance or richness depending on the successional stage were discovered. While some changes in community structure were noted, due to low overall abundance, no clear indicators of brownfield successional stage were identified. For future research on urban brownfield oribatid fauna with the intention of finding potential bioindicators of brownfield properties, increasing the sampling size and inclusion of other groups of soil mesofauna is recommended.
Additional contributions to the knowledge of Philippine predatory mites mainly of the subfamilies Cunaxinae and Cunaxoidinae (Acari: Prostigmata: Cunaxidae)

Published: July 2021

A new species of cunaxid mite belonging to the subfamily Cunaxinae, Cunaxa minidiscondyla sp. nov., is described from the Philippines. This species is distinctive by the presence of a small disc-shaped apophysis dorsodistally on the palp telofemur, two spine-like setae on the palp genu, a long spine-like seta on the palp tibiotarsus, an ill-defined propodosomal shield, the absence of a median hysterosomal shield, long hysterosomal setae, and basifemoral and telofemoral chaetotaxy of 4-4-3-1 and 5-5-4-4, respectively. The previously unknown female of Lupaeus longisetus (Cunaxoidinae) and unknown male of Dactyloscirus trifidus (Cunaxinae) are described. A supplementary description is provided for Scutopalus clavatus (Cunaxoidinae) which is recorded for the first time in the Philippines on coconut leaves infested with the scale insect, Aspidiotus rigidus. New locality and habitat data are given for some species of the aforementioned subfamilies, as well as the subfamilies Bonzinae and Orangescirulinae.
A new species of Arrenurus (Acari, Parasitengona, Hydrachnidia) found in the crop of a Yellow-billed Teal Anas flavirostris in Bolivia
Authors: Valdecasas Antonio G.
Published: July 2021

New findings of organismal dispersal by other organisms can help explain the distribution of species to remote places. In this work, I describe a male and a female of a new water mite species of the genus Arrenurus that were found in the crop of an Anas flavirostris duck near Cochabamba, Bolivia. Both specimens were complete; however, it is unknown if they were alive and, thus, potentially viable at the time of collection. This study also represents the first reported finding of water mites in a bird crop.

Published: July 2021

Tetranychus urticae Koch is a cosmopolitan pest that causes damage to crops in protected farming activities in the semiarid region of the state of Pernambuco, Brazil. We investigated the lethal and sublethal effects of the essential oil from the latex of the mango fruit [Mangifera indica, Espada and Rosa (MESPA and MROSA) varieties] and selected monoterpenes on T. urticae. The yield of the MROSA oil was higher (9.22 ± 0.15%). The GC/MS analysis of the oils enabled the identification of 26 constituents. Terpinolene (70.14 ± 0.61%) was the major compound identified in the MESPA oil; β-pinene (38.22 ± 0.80%) was the major constituent of the MROSA oil, followed by terpinolene (29.44 ± 0.29%). The mite was more susceptible to the oils and constituents through fumigation, with no difference between the two varieties. By residual contact, the MROSA oil was 2.7-fold more toxic than the MESPA oil. Terpinolene was the most toxic constituent by fumigation, whereas β-pinene and α-pinene were the most active by residual contact. The selected compounds from M. indica also affected the behavior of the mite, exerting an influence on fecundity, feeding preference and egg-laying preference. The positive control (Azamax®) was more efficient at reducing the fecundity of the mite than the oils, but the MROSA oil was more toxic by fumigation and residual contact. The effects of fumigation and residual contact combined with the change in behavior may be a considerable advantage in the integrated management of T. urticae. For the practical use of these oils as novel acaricides, however, further investigations are needed to evaluate the effects on non-target organisms and the cost-benefit ratio for the formulation of a product to be used on protected crops in the semiarid region of the state of Pernambuco, Brazil.
New and rare species of hyporheic water mites from New Zealand (Acari: Hydrachnidia: Aturidae, Momoniidae), with the description of two new genera, one new subgenus and one new species
Authors: Smit Harry
Published: July 2021

Recently collected material as well as material collected in the 1960s of Zelandopsis aturoides Schwoerbel, 1984 shows that this species does not belong in Zelandopsis, but in a new genus described in this paper. Moreover, a new genus was found in recent material from New Zealand, i.e. Acidoturus n. gen., with the type species A. parviscutatus n. sp.. A new subgenus of Momonia, i.e. Zelandomomonia, is erected to accommodate M. hopkinsi Schwoerbel, 1984. Furthermore, a redescription is given for Zelandopsis morimotoi Imamura, 1977 and the first description is given of the female of Notohygrobates kathrynae Cook, 1983.
