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. -

O objetivo deste estudo foi determinar as exigências térmicas de Aprostocetus hagenowii em ootecas de Periplaneta americana, bem como a influência das diferentes temperaturas na biologia do parasitoide. Ootecas com idade máxima de oito dias e peso variando entre 0,09 e 0,10 g foram individualizadas em placas de Petri com um casal de A. hagenowii, ficando expostas ao parasitismo. Parasitoides e ootecas permaneceram juntos por 24 h a 25°C; após esse período, os casais foram retirados e as placas contendo ootecas foram transferidas para câmaras às temperaturas de 15, 20, 25, 27, 30 e 35°C. Para cada temperatura foram realizadas trinta réplicas. A duração do ciclo (ovo-adulto) de A. hagenowii apresentou uma tendência inversa à temperatura. A maior viabilidade de emergência do parasitoide (70%) encontrada neste estudo foi à temperatura de 25°C e a menor viabilidade (50%) ocorreu na temperatura de 30°C. -
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. -

Abstract: This is the first report of two ectoparasitoid wasps, Elachertus inunctus (Nees, 1834) in Iran and Elachertus pulcher (Erdös, 1961) (Hym.: Eulophidae) in the world, that parasitize larvae of the tomato leaf miner, Tuta absoluta (Meyrick, 1917) (Lep.: Gelechiidae). The specimens were collected from tomato fields and greenhouses in Ahwaz, Khouzestan province (south west of Iran). Both species are new records for fauna of Iran. The knowledge about these parasitoids is still scanty. The potential of these parasitoids for biological control of T. absoluta in tomato fields and greenhouses should be investigated.

D ^browski received 18.VIII.2003 Abstract: New trophic relationships between Braconidae, Ichneumonidae, Chaleididae, Pteromalidae, Encyrtidae, Torymidae, Eulophidae (Hymenoptera) and burnets (Lepidoptera, Zygaenidae) collected in selected regions of southern Poland are considered. Introduction Over 30 species of insects from the family Zygaenidae (Lepidoptera) occur in Central Europe. The occurrence of sixteen of them was reported in Poland (D/^browski & Krzywicki , 1982; D/^browski, 1998). Most of these species are decidedly xerothermophilous, i.e. they inhabit dry, open and strongly insolated habitats. Among the species discussed in this paperZygaena (Zygaena) angelicae O chsenheimer, Z. (Agrumenia) carniolica (Scopoli) and Z (Zygaena) loti (Denis & Schiffermuller) have the greatest requirements in this respect, and they mainly live in dry, strongly insolated grasslands situated on lime and chalk subsoil. The remaining species occur in fresh and moist habitats, e. g. in forest meadows and peatbogs. Due to overgrowing of the habitats of these insects with shrubs and trees as a result of natural succession and re forestation, or other antropogenic activities (urbanization, land reclamation) their numbers decrease, and they become more and more rare and endangered. During many years of investigations concerning the family Zygaenidae their primary and secondary parasitoids belonging to several families of Hymenoptera were reared. The host species were as follows: Adscita (Adscita) statices (L.), Zygaena (Mesembrynus) brizae (Esper), Z (Mesembrynus) minos (Denis & Schiffermuller), Z. -

Large-scale deployment of Bt-transgenic crops with resistance to H. armigera may have potential consequences for the development and survival of C. chlorideae. Therefore, we studied the tritrophic interactions of C. chlorideae involving eight insect host species and six host crops under laboratory conditions. The recovery of H. armigera larvae following release was greater on pigeonpea and chickpea when compared with cotton, groundnut and pearl millet. The parasitism by C. chlorideae females was least with reduction in cocoon formation and adult emergence on H. armigera larvae released on chickpea. Host insects also had significant effect on the development and survival of C. chlorideae. The larval period of C. chlorideae was prolonged by 2–3 days on Spodoptera exigua, Mythimna separata and Achaea janata when compared with H. armigera, Helicoverpa assulta and Spodoptera litura. Maximum cocoon formation and adult emergence were recorded on H. armigera (82.4% and 70.5%, respectively) than on other insect hosts. These studies have important implications on development and survival of C. -
Attraction of Trichogramma Wasps to Brassica Nigra Plants Induced by Lepidopteran Eggs
Attraction of Trichogramma wasps to Brassica nigra plants induced by lepidopteran eggs Ilich A. Figueroa Supervisors: Nina Fatouros, Ties Huigens Examiner: Marcel Dicke MSc. Minor Thesis– ENT-80424 Report no. 010.27 MSc Plant Science Program Laboratory of Entomology Wageningen University December, 2010 Abstract Plants possess a broad spectrum of defense mechanisms against herbivore attack. The black mustard Brassica nigra, is able to display early defense mechanism against egg infestation by pierid butterflies. This plant shows induced direct defense through hypersensitive response (HR), which kills the eggs as well as indirect defense by the emission of egg-induced plant volatiles that attract egg parasitoids such as Trichogramma wasp. In this study, I investigate whether B. nigra plants infested by the small cabbage white butterfly (Pieris rapae) or the cabbage moth (Mamestra brassicae) express both kind of defense strategies, and whether plants expressing HR still attract Trichgramma wasps in the laboratory and in nature. Tests in the y-tube olfactometer showed that volatiles of plants infested with P. rapae eggs 24h after egg deposition were attractive to the egg parasitoid Trichogramma brassicae when tested against volatiles of uninfested plants. All tested P. rapae-infested plants expressed HR 24h after oviposition. In contrast, plants infested with M. brassicae eggs did not express HR. Volatiles of M. brassicae egg-infested plants were attractive to T. brassicae only when tested against clean air but not when tested against volatiles of uninfested plants. In nature, 77% of the P. rapae eggs collected from HR+ B. nigra plants died, whereby 37% because of Trichogramma parasitism. Eggs collected on HR- B. -

Thus, it is particularly important to develop alternative strategies to control this pest. Over a 4-year period, a survey was done in order to acquire knowledge about the complex of parasitoids associated with this pest. Leaves, flowers, and fruit infested with larvae and pupae of P. oleae were collected from olive groves, conditioned in vials, and kept under laboratory conditions until the emergence of P. ol e ae adults or parasitoids. The abundance and richness of parasitoids as well as the rate of parasitism was estimated. Hymenoptera parasitoids were found to be responsible for 43% of the mean mortality of the sampled individuals.
