P o n t Summary Information about the Fanniidae and Muscidae Houseflies of the south Atlantic island group of Tristan da Cunha, from the earliest records to the most recent findings, is presented and discussed. In total, five species belonging to four genera are recorded. This includes the finding for the first time of Fannia albitarsis St e in , 1911 in the archipelago and Muscina stabulans (Fa ll e n , 1817) on Nightingale Island. Based on material collected in 2005 from the two northern islands, Tristan da Cunha and Nightingale, records and notes are given on four species. A discussion of the correct taxonomic rank of Coenosia trina W ie d e m a n n , 1830 is given. The apparent proliferation of this species, and the possible implications that this may have on endemics, is noted. -

Changes in vegetation structure can alter the physical habitat structure, thermal environment, and food available to arthropods, which play an important role in the structure and functioning of Arctic ecosystems. Not only do they provide key ecosystem services such as pollination and nutrient cycling, they are an essential food source for migratory birds. In this study I examined the relationships between the abundance, diversity, and community composition of arthropods and the height and cover of several shrub species across a tundra-shrub gradient in northwestern Alaska. To characterize nestling diet of common passerines that occupy this gradient, I used next-generation sequencing of fecal matter. Willow cover was strongly and consistently associated with abundance and biomass of arthropods and significant shifts in arthropod community composition and diversity. -
ELIZABETH LOCKARD SKILLEN Diversity of Parasitic Hymenoptera
ELIZABETH LOCKARD SKILLEN Diversity of Parasitic Hymenoptera (Ichneumonidae: Campopleginae and Ichneumoninae) in Great Smoky Mountains National Park and Eastern North American Forests (Under the direction of JOHN PICKERING) I examined species richness and composition of Campopleginae and Ichneumoninae (Hymenoptera: Ichneumonidae) parasitoids in cut and uncut forests and before and after fire in Great Smoky Mountains National Park, Tennessee (GSMNP). I also compared alpha and beta diversity along a latitudinal gradient in Eastern North America with sites in Ontario, Maryland, Georgia, and Florida. Between 1997- 2000, I ran insect Malaise traps at 6 sites in two habitats in GSMNP. Sites include 2 old-growth mesic coves (Porters Creek and Ramsay Cascades), 2 second-growth mesic coves (Meigs Post Prong and Fish Camp Prong) and 2 xeric ridges (Lynn Hollow East and West) in GSMNP. I identified 307 species (9,716 individuals): 165 campoplegine species (3,273 individuals) and a minimum of 142 ichneumonine species (6,443 individuals) from 6 sites in GSMNP. The results show the importance of habitat differences when examining ichneumonid species richness at landscape scales. I report higher richness for both subfamilies combined in the xeric ridge sites (Lynn Hollow West (114) and Lynn Hollow East (112)) than previously reported peaks at mid-latitudes, in Maryland (103), and lower than Maryland for the two cove sites (Porters Creek, 90 and Ramsay Cascades, 88). These subfamilies appear to have largely recovered 70+ years after clear-cutting, yet Campopleginae may be more susceptible to logging disturbance. Campopleginae had higher species richness in old-growth coves and a 66% overlap in species composition between previously cut and uncut coves. -
Population Dynamics of Tomato Russet Mite, Aculops Lycopersici (Massee) and Its Natural Enemy, Homeopronematus Anconai (Baker)
JARQ 38 (3), 161 – 166 (2004) http://www.jircas.affrc.go.jp REVIEW Population Dynamics of Tomato Russet Mite, Aculops lycopersici (Massee) and Its Natural Enemy, Homeopronematus anconai (Baker) Akira KAWAI1* and Mohd. Mainul HAQUE2 Department of Fruit Vegetables, National Institute of Vegetables and Tea Science (Ano, Mie 514–2392, Japan) Abstract Developmental rates of Aculops lycopersici increased linearly as rearing temperature increased. A total of 81.2 degree-days above a developmental zero of 10.5°C were required to complete develop- ment from egg to adult emergence. Adult longevity decreased with increasing temperature. The high- est intrinsic rate of natural increase was observed at 25°C as 0.253 per day. The population increased exponentially on greenhouse tomato plants and the intrinsic rate of natural increase was estimated to be 0.175 per day. A. lycopersici first reproduced on the released leaves then moved upward. The infesta- tion caused great injury to the plants, with a large number of leaves turning brown and then drying up. The number of leaves, the plant height and the diameter of the main stem of the plants all decreased. Homeopronematus anconai naturally occurred on tomato plants. After the rapid population increase of H. anconai, the A. lycopersici population decreased sharply. An adult H. anconai consumed an aver- age of 69.3 A. lycopersici deutonymphs per day in the laboratory. H. anconai was thought to be a pro- spective natural enemy of A. lycopersici.

Final Report 1
Sand pit for Biodiversity at Cep II quarry Researcher: Klára Řehounková Research group: Petr Bogusch, David Boukal, Milan Boukal, Lukáš Čížek, František Grycz, Petr Hesoun, Kamila Lencová, Anna Lepšová, Jan Máca, Pavel Marhoul, Klára Řehounková, Jiří Řehounek, Lenka Schmidtmayerová, Robert Tropek Březen – září 2012 Abstract We compared the effect of restoration status (technical reclamation, spontaneous succession, disturbed succession) on the communities of vascular plants and assemblages of arthropods in CEP II sand pit (T řebo ňsko region, SW part of the Czech Republic) to evaluate their biodiversity and conservation potential. We also studied the experimental restoration of psammophytic grasslands to compare the impact of two near-natural restoration methods (spontaneous and assisted succession) to establishment of target species. The sand pit comprises stages of 2 to 30 years since site abandonment with moisture gradient from wet to dry habitats. In all studied groups, i.e. vascular pants and arthropods, open spontaneously revegetated sites continuously disturbed by intensive recreation activities hosted the largest proportion of target and endangered species which occurred less in the more closed spontaneously revegetated sites and which were nearly absent in technically reclaimed sites. Out results provide clear evidence that the mosaics of spontaneously established forests habitats and open sand habitats are the most valuable stands from the conservation point of view. It has been documented that no expensive technical reclamations are needed to restore post-mining sites which can serve as secondary habitats for many endangered and declining species. The experimental restoration of rare and endangered plant communities seems to be efficient and promising method for a future large-scale restoration projects in abandoned sand pits. -

The grub incidence was reported from 28-39th SMW. Simultaneously, random samples of mined leaves were collected from the surveyed plots, brought to the laboratory, examined for field parasitism symptoms, maintained and reared for further investigations, re- covered the association of hispa grubs or pupae with a gregarious parasitoid, which was identified as Chrysonotomyia sp. (Hymenoptera: Eulophidae: Entedoninae). Also, the maximum parasitization rates for this vary species of parasitoid were recorded during 34-39th SMW, with the mean parasitization of 46.0 and 39.3 percent during kharif 2015 and 2016, respectively. The natural parasitization of grubs or pupae of rice hispa by Chrysonotomyia sp. was reported for the first time from the state and it thus could be exploited as an important biological tool under the sustainable approach for its integrated management. -

International Symposium on Biological Control of Arthropods 424 Poster Presentations ______
POSTER PRESENTATIONS ______________________________________________________________ Poster Presentations 423 IMPROVEMENT OF RELEASE METHOD FOR APHIDOLETES APHIDIMYZA (DIPTERA: CECIDOMYIIDAE) BASED ON ECOLOGICAL AND BEHAVIORAL STUDIES Junichiro Abe and Junichi Yukawa Entomological Laboratory, Kyushu University, Japan ABSTRACT. In many countries, Aphidoletes aphidimyza (Rondani) has been used effectively as a biological control agent against aphids, particularly in greenhouses. In Japan, A. aphidimyza was reg- istered as a biological control agent in April 1999, and mass-produced cocoons have been imported from The Netherlands and United Kingdom since mass-rearing methods have not yet been estab- lished. In recent years, the effect of imported A. aphidimyza on aphid populations was evaluated in greenhouses at some Agricultural Experiment Stations in Japan. However, no striking effect has been reported yet from Japan. The failure of its use in Japan seems to be caused chiefly by the lack of detailed ecological or behavioral information of A. aphidimyza. Therefore, we investigated its ecological and behavioral attributes as follows: (1) the survival of pupae in relation to the depth of pupation sites; (2) the time of adult emergence in response to photoperiod during the pupal stage; (3) the importance of a hanging substrate for successful mating; and (4) the influence of adult size and nutrient status on adult longev- ity and fecundity. (1) A commercial natural enemy importer in Japan suggests that users divide cocoons into groups and put each group into a plastic container filled with vermiculite to a depth of 100 mm. However, we believe this is too deep for A. aphidimyza pupae, since under natural conditions mature larvae spin their cocoons in the top few millimeters to a maxmum depth of 30 mm. -
