Evaluating Policy Representation with Dynamic MRP Estimates: Direct Democracy and Same-Sex Relationship Policies in the United States
Authors: Lewis Daniel C. , Jacobsmeier Matthew L. 
Published: November 2017

AbstractDoes direct democracy strengthen popular control of public policy in the United States? A major challenge in evaluating policy representation is the measurement of state-level public opinion and public policy. Although recent studies of policy responsiveness and congruence have provided improved measures of public opinion using multilevel regression and poststratification (MRP) techniques, these analyses are limited by their static nature and cross-sectional design. Issue attitudes, unlike more general political orientations, often vary considerably over time. Unless the dynamics of issue-specific public opinion are appropriately incorporated into the analyses, tests of policy responsiveness and congruence may be misleading. Thus, we assess the degree of policy representation in direct democracy states regarding same-sex relationship recognition policies using dynamic models of policy adoption and congruence that employ dynamic MRP estimates of attitudes toward same-sex marriage. We find that direct democracy institutions increase both policy responsiveness and congruence with issue-specific public opinion.
Silica nanoparticles induce NLRP3 inflammasome activation in human primary immune cells
Authors: Gómez Diana M , Urcuqui-Inchima Silvio , Hernandez Juan C 
Published: November 2017

In recent years, the potential use of silica nanoparticles (SiNPs) among different biomedical fields has grown. A deep understanding of the physicochemical properties of nanoparticles (NPs) and their regulation of specific biological responses is crucial for the successful application of NPs. Exposure to NP physicochemical properties (size, shape, porosity, etc.) could result in deleterious effects on cellular functions, including a pro-inflammatory response mediated via activation of the NLRP3 inflammasome. The aim of this study was to evaluate the potential in vitro immunomodulatory effect of 12-nm and 200-nm SiNPs on the expression of pro-inflammatory cytokines and NLRP3 inflammasome components in human primary neutrophils and PBMCs. This study demonstrates that regardless of the size of the nanoparticles, SiNPs induce the production of pro-inflammatory cytokines in a dose-dependent manner. Induced IL-1β production after exposure to SiNPs suggests the involvement of NLRP3 inflammasome components participation in this process. In conclusion, SiNPs induce the production of pro-inflammatory cytokines in a dose-dependent manner. Furthermore, our data suggest that the production and release of IL-1β possibly occurs through the formation of the NLRP3 inflammasome.
Comparison of coleopteran fauna in olive orchards under different production systems in the Messara’s valley, on Crete island, Greece
Authors: Tzokas I. , Liantraki Z. , Kollaros D. 
Published: November 2017

In this study the results of the captured Coleoptera in pitfall traps in nine olive orchards in the valley of Messara, on Crete Island, were compared. The liquid used for killing and preservation in the pitfall traps, was propylene glycol. The nine olive orchards were distributed in four areas in the valley. In each area there were at least two olive orchards under different agricultural management system, organic and conventional. The experiments were conducted from October 2004 to April 2005. The number of captured Coleoptera specimens was 4,937. The specimens were identified to the family level. Coleoptera from 25 families were found, but the analysis was focused at eleven of them, the richest in specimens. These were: Anthicidae, Carabidae, Chrysomelidae, Curculionidae, Histeridae, Leiodidae, Scarabaeidae, Silphidae, Silvanidae, Staphylinidae and Tenebrionidae. Staphylinidae were the most abundant in all olive orchards independently of the agricultural management (production system). In the other families instead of differences amongst the different systems of agricultural management, more prominent were the differences amongst areas.
Establishment of economic injury levels for olive infestation by Dαcus oleαe, in Corfu
Authors: Kapatos Ε.Τ. , Fletcher B.S. 
Published: November 2017

Economic injury levels for cover sprays and air bait sprays were established for the infestation by Dacus oleae (Gmelin) (Diptera: Tephritidae). For cover sprays, the economic injury levels (expressed as percent infestation by taking 30,000 fruits to represent the average number of fruits per tree) were calculated as 7.59% for infestation laid in late July-August, 6.16% for infestation in September and 10.31% for infestation in October. For air bait sprays, economic injury levels were calculated for various fruiting conditions (expressed as proportion of trees bearing olive fruits) and they were much lower than for cover sprays due to the lower cost of air treatments. For July-August, they ranged from 5.07% infestation for 25% trees bearing olives to 1 .27% for 100% trees with olive fruits. For September they ranged from 4.11% to 1.08% infestation, for October they ranged from 6.88% to 1 .72% infestation and for infestation laid in November they ranged from 61.28% to 15.32% infestation, respectively. The economic injury levels for air bait sprays were also expressed as mean weekly number of females per McPhail trap by taking into account the potential fecundity of D. oleae and the efficiency of the McPhail trap (baited with protein hydrolysate 2% and borax 1 .5%) at different times of the year. For September, they ranged from 16 females per trap for groves with 25% of trees bearing olive fruits, to 4 females per trap for 100% trees with fruits. For October, they ranged from 6 females per trap to I female per trap, respectively.
Nathrius brevipennis (Mu1sant 1839) (Col.: Cerambycidae) in Greece
Authors: Santas L.A. 
Published: November 2017

In the spring of 1975, the trees of an almond orchard [Prunus dulcis (Miller) D.A. Webb] in Avliotes Corfu, were found to be severely infested by a wood borer insect in the larval stage. Samples of infested with larvae twigs, preserved in the laboratory, and in the same year in September a number of adults emerged. After identification this insect was found to be Nathrius (Leptidea) brevipennis (Mulsant 1839). This species caused important damage in the almond trees of the Avliotes area of Corfu during the years 1975-1976. In 1977, N. brevipennis was found in Ioannina county on walnut trees (Juglans regia L.) and in 1980, it was found in Metsovo area on almond trees.
Anapulvinaria pistaciae (Bod.), a pistachio tree scale pest producing honeydew foraged by bees in Greece
Authors: Santas L.A. 
Published: November 2017

The soft scale Anapulvinaria pistaciae (Bod.), a pest of pistachio, excretes honeydew which is exploited by honeybees. The scale has one generation per year. Adults appear early in spring and crawlers in May. From mid-May to mid-June the population of A. pistaciae consists mainly of crawlers and/or first stage nymphs. The second stage nymphs appear early in fall, this is the over-wintering stage, from which the adults of the next generation will emerge the following year.
Male attraction tο virgin females in the almond seed wasp, Eurytomα amygdali Enderlein (Hymenoptera, Eurytomidae)
Authors: Pittara I.S. , Katsouannos Β.Ι. 
Published: November 2017

Laboratory observations showed that adults of the almond seed wasp, Eurytoma amygdali Enderlein (Hymenoptera: Eurytomidae) were sexually mature on the first day of emergence. Experiments with an olfactometer showed that 1 to 12 day-old virgin females attracted the males. This attraction was found to be due to an odor, apparently a pheromone, released by the virgin females. The responsiveness of the males was higher the first part of the photophase. Under field conditions too, virgin females were attractive to males. “Delta” traps, containing 5-20 virgin females, suspended on almond trees, attracted and captured males released among the same trees. On the contrary, traps containing mated females or empty cages were not attractive to males.
Effect of size, color and height of pheromone baited sticky traps on captures of Dacus oleae flies
Authors: Haniotakis G.E. 
Published: November 2017

The size of sticky pheromone traps has no effect on Dacus οleae catches when insect population densities are low. At high population densities trap catches increase with surface area. There were no differences in the numbers of D. οleae caught on yellow and white pheromone traps in periods of high pheromone effectiveness, which coincide with periods of high insect reproductive activity. During periods of reduced pheromone effectiveness, due either to low temperatures at the time of pheromone activity (dusk) or reduced insect reproductive activity, traps of yellow hues tend to capture more insects than traps of white color. The height at which pheromone traps are located inside the tree canopy has no effect on catches of D. οleae.

Βacterial flora isolated from the oesophageal bulb of the olive fruit fly Dacus oleae (Gmelin)
Authors: Stamopoulos C. , Tzanetakis Ν. Μ. 
Published: November 2017

In a study of the bacterial flora occurring in the adults of the olive fruit fly, Dacus oleae (Gmelin) (Diptera: Tephritidae), oesophageal diverticulum, a total of 28 strains were obtained. Six of them were Gram – negative and identified as Pseudomonas niendocina, Morarella nonliquefasciens (2), Alcaligenes sp., Enterobacter cloacae (2) and 22 Gram-positive classified as Kurthia sp., Staphylococcus subgroup VI, Micrococcus roseus, Bacillus pumilus, B. licheniformis (3) and B. subtilis(15). None of the above bacteria are strictly fixed and constantly present in the oesophageal diverticulum, suggesting that the bacterial flora associated with D. oleae depends on environmental factors, and could be used as a nutrient source for the insect apart from its possible other symbiotic role.
Control of Cydia molesta (Busck) by mating disruption using Isomate-M pheromone dispensers in Northern Greece
Authors: Kyparissoudas S. 
Published: November 2017

Trials were carried out in 1986 and 1987 with the mating disruption method for the control of oriental fruit moth (Cydia molesta Busck) in peaches of Northern Greece. One or two applications during April-September of the synthetic pheromone lsomate-M, at a rate of 1,000 units per ha, resulted in a 100% prevention of captures in pheromone traps in all trials, with fruit damage ranging from 0.1-2.0%. Damage in the conventionally sprayed treatments was 0.3-2.4% while infestation in the unsprayed plots reached 6-17%. The encouraging results, especially when taking into account the relatively small size of the orchards, opens opportunities for the integrated control of this peach insect pest under the condi­tions of Northern Greece.

Species which are considered to be stored product insects are noticed while a special reference is made to Lasioderma spp. found on thistles.
Simultaneous control of Cydia molesta and Anarsia lineatella in peach orchards of Northern Greece by combining mating disruption and insecticide treatments
Authors: Kyparissoudas S. 
Published: November 2017

Trials were carried out in 1987 and 1988 on the combined control of oriental fruit moth (OFM), Cydia molesta (Busck), and peach twig borer (PTB), Anarsia lineatella (Zell), in peach orchards in Northern Greece with Isomate-M pheromone dispensers (mating disruption technique) and insecticides against OFM and PTB, respectively. One application of the Isomate-M at a rate of 1,000 units per ha, and one application of the insect growth inhibitor (IGI) hexaflumuron 5 EC (200 ml f.p,/hl) or two sprays of fluvalinate 25 AF (60 ml f.p./hl) during June provided satisfactory control of OFM and PTB. Total damage per tree in the trials reached 1.0-3.6%, versus 1.4-3.0% in the conventionally sprayed orchards, while in unsprayed control blocks it was 14.4-23k. These encouraging results open possibilities for the combined control of these peach insects in Northern Greece.
Development of Leucoma salicis (L.) (Lepidoptera: Lymantriidae) on Populus alba (L.) and Poplar Clone “I-214”
Authors: Avtzis N.D. 
Published: November 2017

Tests were made to determine if the phytophagous insect Leucoma salicis (L.) (Le­pidoptera: Lymantriidae), preferred Populus alba (L.) or Poplar Clone “I-214” as its host. These tests were based on field observations in experimental plots at the nursery of the Forest Research Institute in Thessaloniki, N. Greece. The observations which continued for a two-year period (1984, 1985) corroborated the high resistance of P. alba to L. salicis. Rearing on this host-plant caused retarded growth, produced lower number of eggs, caused higher larval mortality and generally showed reduced development always, in comparison with the rearing of this insect on leaves of Clone “I-214”.
Population dynamics of Saissetia oleae. Ι. Assessments of ροpulation and mortality
Authors: Stratopoulou E. T. , Kapatos Ε.Τ. 
Published: November 2017

The population dynamics of Saisselia oleae (Oliv.) (Homoptera: Coccidae) was studied in Corfu during five successive yearly generations (1981-1986). Successive estimates of the population of S. oleae were obtained within each of the five yearly generations and survivorship curves were constructed showing the progressive re­duction of the living population within each generation and population changes from generation to generation. The calculated mortality rates indicate that the population of S. oleae suffers heavy mortality. The major mortality factors were high temperatures during summer, the action of predators, particularly during spring, and mortality of crawlers during summer. Overall survival rate was very low and corresponded to total generation mortality that ranged from 99.693% to 99.987%. It is assumed that variation in the action of mortality factors cause considerable I’l Uctuations of the S. oleae population.
Population dynamics of Saissetia oleae. II. Life-tables and key-factor analysis
Authors: Kapatos E. T. , Stratopoulou E.T. 
Published: November 2017

A series of life-tables for the population of Saisselia oleae (Oliv.) (Homoptera: Coccidae) during five yearly generations (1981-86) were constructed in Corfu. Key-factor analysis carried out on the life-table data indicated that mortality of young stages during summer, caused mainly by the high temperatures, and mortality during spring, caused mainly by predation, determine total population change within each generation. These two mortality factors are the predominant factors of the population dynamics of S. oleae determining population fluctuations. The other mortality factors of the population system of S. oleae were less important. Summer parasites and egg predators, in particular, do not play any significant role on the population dynamics of S. oleae.

First Record of Aleurothrixus floccosus (Mask.) (Homoptera: Aleyrodidae) in Greece and Some Observations οn its Phenology
Authors: Katsouannos P. 
Published: November 2017

Aleurothrixus.floccosus was first found in Greece on citrus trees in several urban areas of East Attica, in May 1991. During the following summer and autumn, all preimaginal instars of the insect were found on sample leaves. Adults were captured on yellow sticky traps throughout this period, until mid-December. During the winter (Dec., Jan.) the majority of the population consisted of third and fourth pre-imaginal instars. For control of A. floccosus, the parasitoid Coles noacki (Hymenoptera: Aphelinidae) was imported into Greece from Spain in late 1991. The introduced populations were successfully multiplied in the insectary.

Observations of Phαceliα tαnαcetifoliα as a Food Plant for Honey Bees and other insects
Authors: Thrasyvoulou Andreas , Tsirakoglou Basilis 
Published: November 2017

Three consecutive sowings of Phacelia tanacetifolia Bentham (Hydrophyllaceae) were examined for plant growth and attractiveness to bees and other insect-visitors over a three years’ study. Plants that were sown in March flowered uniformly for periods of 24 to 40 days, while those sown in June and July had a non-uniform anthesis that was impossible to estimate. Plants sown in early August, remained vegetative throughout winter and flowered the following spring. Maximum visits of honey bees were observed between 10:00 h and 17:00 h. Most honey bees (>70%) collected nectar. Seasonal differences in the ratio nectar/pollen gatherers were noted. Two species of bumble bee (B. terrestris and B. lucorum) and 9 species of solitary bee visited Phacelia.
First Record of Cheiloneurus clαviger (Thomson) (Hymenoptera: Encyrtidae) on Corfu Island
Authors: Macropodi M.V. , Viggiani G. 
Published: November 2017

During an ongoing research programme on Saissetia oleae (Oliv.) (Homoptera: Coccidae) and its parasites on the island of Corfu, the presence of the hyperparasite Cheiloneurus clαviger (Thomson) (Hymenoptera: Encyrtidae) was recorded, for the first time, in samples of parasitized Saissetia oleae in 1991. The identification of C. clagiver was made by the junior author. The adults of Cheiloneurus clαviger emerged from S. oleae females parasitized by Metaphycus lounsburyi (How.) (Hymenoptera: Encytridae), after they were placed in plastic capsules. Tables 1 and 2 give the number of adults of S. oleae, C. claviger and M. lounsburyi that emerged from S. oleae at two experimental fields. M. lounsburyi is one of the main parasitoids of S. oleae acting as an internal parasite of the fourth larval instar. The numbers of C. claviger emerged were very low compared with the numbers of M. lounsburyi, indicating that at present C. claviger is not a serious limiting factor for the population of M. lounsburyi. The presence of a group of coarse bristles at the apex of the scutellum and the long marginal vein of fore wings are the peculiarities of the genus Cheiloneurus. The incomplete infuscation of the fore wings and the colour of the antennae with only the 5th funicular segment blackish can easily allow the discrimination of C. claviger females from those of congeneric species. Cheiloneurus clαviger is reported as a hyperparasitoid of several coccids of economic impor tance mainly via other encyrtid parasitoids. In Italy, C. claviger has been found to act as a hyperparasite of Kermesidi (genus Kermes) which infest Pinoideae. Previous reports on the entomophagous fauna of S. oleae on Corfu do not include C. claviger and it is assumed that the hyperparasitoid has been introduced rather recently. The actual role oil the parasitic complex of S. oleae and the distribution of this hyperparasite on the island should be further investigated.
The effect of amino acid analogues on larval growth and survival of the olive fruit fly Bαctrocerα oleαe (Diptera: Tephritidae)
Authors: Manoukas Α. G. 
Published: November 2017

The effects of eight amino acid analogues [L-canavanine, D-cycloserine, allylglycine, L-glutamic acid-A-hydrazide, DL-ethionine, L-,-3,4 dihydroxyphenylalanine (L-DOPA), DL-,-3,4 dihydroxyphenyl-alanine (DL-DOPA) and thiaproline] added to an artificial diet on egg hatching, larval survival, larval weight, pupal weight and adult emergence of the olive fruit fly, Bactrocera oleae (Gmelin) (Diptera: Tephritidae) were investigated. Larval survival and weight were significantly decreased by all amino acid analogues tested. Pupal weight and adult emergence was depressed by L-canavanine, D-cycloserine, L-DOPA, DL-DOPA and allyl-glycine. Of all amino acid analogues tested only L-canavanine inhibited hatching of the eggs. The depression of the parameters affected was increased by increasing the concentration of each analogue tested. The larvae of most experimental diets took longer to pupate than those of the control.
