The occurrence of Encarsia perniciosi in areas of northern Greece as assessed by sex pheromone traps of its host Quadraspidiotus perniciosus
Authors: Kyparissoudas D.S. 
Published: November 2017

During the 1982-1985 period the aphelinid endoparasite Encarsia perniciosi Tower was captured on synthetic pheromone traps of the San Jose scale (SJS), Quadraspidiotus perniciosus Comstock, in scale-infested insecticide treated and untreated orchards of Central and Western Macedonia (Northern Greece). It has expanded especially near the sites where it had been released, but also in areas 50-100 km from the point of release. The parasite in untreated orchards generally appeared from April to October, while in orchards treated with insecticides it was not caught after mid June. Spring flights of the parasite occurred on almost the same dates as the first captures of the male scale. Subsequent flights of E. perniciosi were not always synchronized with those of the male scale, and after the beginning of June the parasite showed a general decline throughout the remainder of each season. The pheromone of the scale insect acts as a kairomone to the parasite and it can be used in trapping systems in scale-infested orchards for the confirmation of the presence and the dis­tribution of E. perniciosi.
Effect of Combining Food and Sex Attractants on the Capture of Dacus oleae Flies
Authors: Haniotakis G.E. , Vassiliou-Waite Α. 
Published: November 2017

Sex pheromonal compounds i.e. the most potent male attractants, and ammonia, one of the most potent female attractants available today for Dacus oleae (Gmelin), were combined on the same trap. This combination resulted in an overall increase of female captures as compared to those of ammonia alone, but a decrease of male captures as compared to those of pheromone alone. Deviations from this overall effect were observed during certain periods of the year and are caused by varying environmental and biological factors which influence insect response to pheromones. Explanations for these results based on recent findings concerning the pheromone system of D. oleae are presented here.
Some enzymatic activities registered in eggs and gut tissues of the olive fruit fly, Dacus oleae (Gmelin)
Authors: Stamopoulos C. 
Published: November 2017

Nineteen enzymatic activities of eggs, gut tissues of larvae and adults of Dacus oleae have been determined using the API-ZYM micromethod. The enzymatic activities of eggs were much weaker than those of larval or adult guts. The activities increased progressively to the L2 and L3. The lack of feeding caused a reduction of certain activities in larvae (alkaline phosphatase, esterases, aminopeptidases) but not in adults. The addition of streptomycin to the food of adults, to obtain “aposymbiotic” individuals, did not have a clear effect on the activities of the insect’s various stages. Although the enzymes studied were not the only ones that occur in the insect’s gut tissues, it seems that there are few similarities between the enzymatic system of larvae and that of adults, most probably because of the different content of the two diets in essential nutrients such as amino acids, proteins, and lipids.
Descriptίοn of Aceria creticα new species from olive trees in Greece (Acari: Εriophyidae)
Authors: Hatzinikolis Ε. Ν. 
Published: November 2017

The female of Aceria cretica, new species, is described and illustrated. This species was found and collected from an isolated group of olive trees (Olea europaea L.) in Crete, Greece. It causes subcircular, greenish patches under leaf surface, similar to those caused by Aceria oleae (Nalepa 1900).

Α New Host Plant for Scobicia cheνrieri (Villa) (Coleoptera: Bostrychidae)
Authors: Buchelos C.TH. 
Published: November 2017

Bostrychidae is primarily a family of wood-boring beetles, distributed mainly in the tropics and subtropics. Many species are serious pests of growing trees and felled timber. One species, Rhysopertha dominica (F.), is a grain borer and the most frequently met among beetles infesting stored wheat in Greece (Buchelos 1981). Two other bostrychids, Dinoderus minutia (F.) and Dinoderus brevis Horn, have been recently found in Greece infesting bamboo articles imported from Hong-Kong and the Philippines respectively. Wooden parts (branches of 3 to 18 cm in diameter) of Brachychiton acerifolium Mull. and Brachychiton diversifolium G. Don. (Sterculiaceae) trees, widely used as ornamentals in alleys and parks in Attika, Greece, that have been cut and stored for one at least year in the open, were found heavily infested by bostrychid bee­tles and their larvae; the exterior of these branches was densely perforated by tunnel openings about 1,5 mm in diameter, while the interior presented an almost complete deterioration due to numerous galleries caused by the insects. Due to the fact that the living Brachychiton trees of the region examined were found infestation free, one is lead to the conclusion that the infestation occurred after felling; furthermore, the infestation on B. acerifolium seemed more severe than on B. diversifolium wooden parts. The identification of the adults, based on taxonomic keys of Lesne 1900, Renter 1911, Por to 1929, Portevin 1931 and Fisher 1950, lead to Scobicia chevrieri (Villa) and was confirmed by the identification group of the Bayerische Staatsamlung, Munich. The species belongs to the subfamily Bostrychinae, tribe Xyloperthini, genus Scobicia Lesne; it has also been found under the synonyms: Apate chevrieri Villa, Apate capilata Dejean, Xylopertha chevrieri J. Duval, Xylopertha foveicollis Allard, Xylopertha pustulate Kiesenwetter and Scobicia pustulate Jacobson. The adults found in the region of Attika, near Athens, are 3.3-4.5 mm long and 1.2 to 1.5 wide. S. chevrieri is reported being distributed in many regions of Italy from the Alpes and Tyrol to Sardinia and Sicily, across the French Mediterranean coast and Corsica, Spain (Malaga, Seville, Cordoba), Morocco, Tunisia, Algeria, Israel, Libanon, Syria, Caucasus, Crimea and Cyprus. In the relevant literature, S. chevrieri is recorded attacking mainly dead branches of the following plants: fig (Ficus sp.), mulberry (Maras sp.), green oak (Quercus ilex L.), English oak (Quercus robur L.), evergreen oak (Quercus coccifera L.), laurel (Laurus nobilis L.), mastic-tree (Pistacia lentiscus L.), birch (Betula sp.), fox grape (Nibs lahrusca L.), pomegranate (Punica granatani), chestnut (Castanea sp.) and gem-tree (Eucalyptus spp.). Brachychiton spp. is recorded here for the first time as host of the insect.
Distribution of Population of Immature Stages of Pear Psylla, Cαcopsyllα pyri, within the Tree and Development of Sampling Strategy
Authors: Stratopoulou E. T. , Capatos E.T. 
Published: November 2017

The distribution of Cacopsylla pyri (L.) (Homoptera-Psyllidae) infestation within the tree canopy and in the varions organs of the tree was investigated in the region of Magnesia (Greece) during 1988 and 1989. The upper parts of the tree canopy and the sections ori­entated to South and west were infested heavier during winter and spring. Later in the scason the infestation was diffused within the tree canopy and at the end of the season a rather uniform pattern of distribution was observed. During the first oviposition period (February-March), the preferred oviposition sites were flower buds white during spring (second generation) they were the leaves of flower buds and young shoots. Sampling strategy for the study of populations of immature stages of pear psylla is discussed on the oasis of these findings.
Phenology of Population of Immature Stages of Pear Psylla, Cαcopsyllα pyri, in the Region of Magnesia (Greece)
Authors: Stratopoulou E. T. , Capatos E.T. 
Published: November 2017

The phenology of the population of immature stages of pear psylla, Cacopsylla pyri (L.), was studied in Greece (region of Magnesia), during the period 1988-1991 and it was found to follow a basic pattern. Pear psylla produces 5-6 gencrations per year. The first generation develops during the period February-middle April and it is quite discrets. Three overlapping generations are developed during the period front middle April until middle August but the amount of overlapping varies front year to year. Front middle August until the end of the season pear psylla produces 1-2 generations, i.e. only a part of the firth generation complotes the sixth one. Population density is generally low during the first generation but during May-June reaches verty high levels. During sommer, strong environmental pressure, supresses the population of pear psylla to low levels but it recovers again during September-October.
Control of Synanthedon (Aegeria) myopaeformis by Mating Disruption Using Sex Pheromone Dispensers in Northern Greece
Authors: Kyparissoudas D.S. , Tsourgianni Α. 
Published: November 2017

In 3 successive years (1990-1992) polyethylene tube dispensers, each containing 50.5 mg synthetic sex pheromone of the apple clearwing moth, Synanthedon (Aegeria) myopaeformis Borkh., were placed at a density of 680 per ha, once a year, in two adjacent commercial apple orchards each I ha in size. The degree of confusion reached almost 100% by releasing about 6 mg/ha/h, whereas the number of mated females decreased by 72.86%, compared with the untreated orchard. In 1993, after 3 years of experiments, a reduction of up to 91% of empty pupal skins per tree was attained. The encouraging results, especially when taking into account the relatively small size of the orchards, opens opportunities for the integrated control of this apple insect pest under the conditions of Northern Greece.
Comparative Field Studies of Various Traps and Attractants for the Olive Fruit fly, Bαctrocerα oleαe
Authors: Haniotakis G.E. , Broumas ΤΗ. , Liaropoulos C. 
Published: November 2017

In the framework of an ongoing effort for development of an effective trap for the control of the olive fruit fly, Bactrocera oleae (Gmelin) (Diptera, Tephrifidae), by mass trapping, four trap types (wood, cloth, laminate, McPhail), seven different colors of laminate traps, different food attractants, attractant combinations or formulations (total of ten cases), and two insecticides (deltamethrin, b-cyfluthrin) used as killing agents on the traps, were compared under field conditions. The following conclusions may be drawn: Laminate traps (paper envelopes with a polyethylene lining inside, 15×20 cm in size, containing 70 g of ammonium bicarbonate salt and impregnated with 15 mg (a.i.) of an insecticide), were more effective than wood traps. Effectiveness of laminate traps can be enhanced by using an attracting color or in the case of the food attractant ammonium bicarbonate, by incorporating copper oxychloride. Combinations of two protein hydrolysates were more effective than one hydrolysate alone. Effectiveness of protein hydrolysates is not constantly higher than that of ammonium bicarbonate, the use of which is more economic and convenient. The insecticide b-cyfluthrin may be used on traps instead of deltamethrin, which is known to have a repellent effect on the olive fly, especially Linder high concentrations, and is unstable under natural UV light.
The Effects of Νatural Enemies on Aphid Populations on Processing Tomato in Central Greece
Authors: Lykouressis Ρ. , Perdikis D. CH. , Chalkia CH. Α. 
Published: November 2017

Two species of aphids, Macrosiphion euphorbiae (Thomas) and Myzus persicae cae (Sulzer) (Homoptera: Aphididae) were the only ones which developed populations on processing tomato in a two year study conducted in central Greece. The aphid population structure showed that M. euphorbiae was much more abundant than M. persicae in both years. The former species peaked in August whilst the latter did not show any particular peak over the two successive years. Some species of natural enemies were recorded. Orius niger Wolff was found in low numbers scattered over a long period but mainly towards the end of the growing season, and it did not correlate with the aphid population. The rate of parasitism of M. euphorbiae by Aphelinus abdominalis Dalman and Praon volucre (Haliday) was very low and it seemed that these two parasitoid species did not have any particular effect on the aphid population suppression. Macrolophus pygmaeus Rambur was the key natural enemy and the most abundant and effective among the predators found. Its highest numbers occurred towards the end of the growing season following the aphid population peak, suggesting a numerical response of this species to its prey. A proportion of the population of M. pygmaeus occurring on tomato plants after fruit harvesting, might he collected and subsequently released in crops such as tomato, pepper and eggplant to biologically control pests in greenhouses, like aphids and whiteflies, thus contributing to the production of healthy vegetable products.
Seasonal development and ovipositing behavior of Marchalina hellenica (Hemiptera: Margarodidae)
Authors: Gounari Sofia 
Published: November 2017

Marchalina hellenica, Gennadius (Hemiptera: Margarodidae) is the main honeydew producing insect of pine trees ίη Greece. Its behavior during oviposition, the reproductive capacity, oviposition period, pre-hatching period, and life span of the οviposited female and other aspects of its reproductive behavior in the field and in the laboratory, have been recorded in a three-year research. Μ. hellenica completes one generation per year. It is mainly parthenogenetic. The adult female appears on the trees, looking for an oviposition site from late March to late April. Its oviposition period in the field lasts about 20 days, while the hatching period lasts about 30 days. Live females can be found on the trees until the end of May, so there is a coexistence of three stages of Μ. hellenica, adult, eggs and 151 stage nymphs, in the field for about one month. Μ. hellenica is able to oviposit in the laboratory in room conditions. Its ovipositing period is as long as 16 days, while the total number of eggs laid is on average 262. Body weight was significantly correlated with the total number of eggs laid.

Published: November 2017

To clarify questions regarding the effectiveness of the many different types of traps and semiochemicals used for the monitoring and the control of the Mediterranean Fruit Fly, Ceratitis capitata (Wiedemann) (Diptera: Τephrititae), seven trap types, four food attractants, one sex attractant and a combination of food and sex attractant, were evaluated under field conditions in orange orchards in fall. No major differences were observed between trap designs resembling the original McPhail glass trap. The plastic bottle trap of 1,5L volume, with four side openings for one-way fly entrance, proved very efficient when filled with a proteinaceous food attractant Ζ1. From the attractants, two of them, Ζ1 and Entomela showed the best performance. The combination of food and a sex attractant showed no significant synergistic effects on trap efficiency. The findings allow a better choice among trap types and attractants, available today in the market, for Medfly monitoring and control.
Prehire Screening and Subjective Performance Evaluations
Authors: Chen Bin R. , Li Sanxi 
Published: November 2017

We study a two-stage model in which the agent’s ability is initially unknown to any party, but the principal can choose a prehire screening scheme to discover the agent’s ability before offering a contract. Perfect screening enables the principal to fine-tune the contract to the agent’s ability, but it also prevents her from enforcing a contract that is contingent on subjective interim performance measures. Given that interim performance measures are critical for motivating first-stage effort, the principal may benefit from adopting no screening or partial screening. When partial screening is employed, the halo effect—a commonly observed bias in subjective evaluation practices—emerges in the equilibrium. This paper was accepted by Shivaram Rajgopal, accounting.
Incentives and Ratcheting in a Multiproduct Firm: A Field Experiment
Authors: Brahm Francisco , Poblete Joaquin 
Published: November 2017

We develop a model and derive behavioral predictions for a multiproduct sales force subject to goals set based on past performance. We test these predictions using a field experiment in which 53 salespersons from a Chilean beverage company face exogenous variations in monthly sales goals. Confirming our predictions, we found that (1) absent strategic considerations—no goal ratcheting—salespersons increase (decrease) sales in the product category for which the return to effort increases (decreases), (2) including strategic considerations behavior reverses: salespersons who expect high goal ratcheting decrease (increase) sales in the category for which the return to effort increases (decreases), (3) sales did not change for the average salespersons, reflecting heterogeneity in the expectations of goal ratcheting rather than unresponsiveness to incentives. Our study points at the importance of the dynamics of incentive design, in particular, the importance of understanding the dynamics of goal setting in firms.

Exploring Phonological Awareness Skills in Children With Intellectual Disability
Authors: Sermier Dessemontet Rachel , de Chambrier Anne-Françoise , Martinet Catherine , Moser Urs , Bayer Nicole 
Published: November 2017

Abstract
The phonological awareness skills of 7- to 8-year-old children with intellectual disability (ID) were compared to those of 4- to 5-year-old typically developing children who were matched for early reading skills, vocabulary, and gender. Globally, children with ID displayed a marked weakness in phonological awareness. Syllable blending, syllable segmentation, and first phoneme detection appeared to be preserved. In contrast, children with ID showed a marked weakness in rhyme detection and a slight weakness in phoneme blending. Two school years later, these deficits no longer remained. Marked weaknesses appeared in phoneme segmentation and first/last phoneme detection. The findings suggest that children with ID display an atypical pattern in phonological awareness that changes with age. The implications for practice and research are discussed.

Abstract
Data from 949 children and adolescents with intellectual disability ages 5 to 16 for whom the Supports Intensity Scale–Children's Version–Catalan Translation was completed was used, in combination with data from the U.S. standardization sample, to examine measurement invariance and latent differences in the Catalonian sample. Results suggest that the same set of items can be used to measure support needs across U.S. and Catalonia samples and that there are age-related differences in support needs in the Catalonia sample, particularly between children ages 5 to 10 and 11 to 16 years of age. This differs from findings with the U.S. sample, where differences were found in a greater number of age cohorts. Implications for future research and practice are discussed.
Wearables for Promoting Physical Activity
Authors: Strath Scott J , Rowley Taylor W 
Published: November 2017

Abstract

BACKGROUND
The rapid expansion and popularity of consumer-wearable physical activity monitors (WPAMs) has enabled the integration of technology into physical activity (PA) intervention, deployment, and evaluation. This brief review reports on the accuracy of consumer-WPAMs, considers the intervention effects of using consumer-WPAMs, and offers future considerations as the proliferation of this area of product development and consumer use continues to escalate.

CONTENT
The studies reviewed document the utility for consumer-WPAMs to objectively assess PA, with output metrics similar to research-grade activity monitors. Early intervention efficacy for the use of consumer-WPAMs to increase PA holds considerable promise. Substantial increases in moderate- to vigorous-intensity PA (MVPA) have been reported across different research study designs and populations in which consumer-WPAMs have been used in isolation or in conjunction with other behavioral change strategies. The utility of consumer-WPAMs is currently being investigated in clinical populations, notably showing increases in PA in individuals at risk for cancer or post cancer survivors, in those with chronic obstructive pulmonary disease, and in postsurgical patients. There has been a proliferation of registered trials at clinicaltrials.gov, and an increase of disseminated works regarding the use of consumer-WPAMs is expected.

SUMMARY
There are many research studies documenting the validity and intervention effectiveness of consumer-WPAMs; evidence is emerging on the health benefits linked to use of such devices. Future work on the long-term effects of consumer-WPAMs on behavior and health is warranted, and prospects appear exciting as wearable technology advances and adoption increases.
Aesthetic perception, attention, and non-genericity: How artists exploit the automatisms of perception to construct meaning in vision
Authors: Bundgaard Peer F. , Heath Jacob , Østergaard Svend 
Published: November 2017

AbstractThe present work is an attempt to bring meaning to the fore of not only empirical aesthetics but also experimental aesthetics. We have addressed meaning in terms of attention-grabbing perceptual structure, doing so in the strong sense of structure; i.e., structure understood as a pure spatial relation between shapes, independently of what objects these shapes represent. The structures we investigate are the so-called non-generic configurations that obtain between objects seen from a unique vantage point. In the paper, we first introduce the notion of non-genericity, in general, and its use in visual art in particular, where it is claimed to affect the visual brain as an attention grabber. We then present an experiment we have designed to test the effect of such a relation on the visual brain, and we give evidence to the effect that non-generic configurations in pictures do attract attention significantly more than their generic counterparts. Non-genericity can therefore be considered as one among other pictorial techniques artists dispose of to construct perceptual meaning in vision.
