These experiments were designed to examine short-range dispersal by the small whitefly parasitoid Eretmocerus eremicus that takes place within the confines of a specifically defined habitat. We were specifically concerned with the impacts of sex and mating status on their dispersal. We hoped to construct predictive models concerning dispersal. In a vertical flight chamber we found that female flight duration was significantly longer (11 times) than that of males and that unmated parasitoids flew approximately three times longer than mated individuals. In field studies 87% of the 4,153 parasito

Habitat fragmentation and the intensification of agricultural landscapes are among the main drivers affecting parasitoid diversity. Although many empirical and theoretical studies have elucidated the effects of these processes on populations and communities of parasitoids, the majority of the research has been focused on specialized groups of hymenopterans. In this study the highly-diverse group of tachinid parasitoids (Diptera: Tachinidae) was considered as an alternative model system to test the effects of landscape fragmentation and agricultural intensification on the third trophic level.

Bibliography: leaves 108-128. Maternal protein secretions from the parthenogenetic endoparasitoid wasp Venturia canescens Gravenhorst (Hymenoptera: Ichneumonidae) were analysed regarding their ability to protect the parasitoid egg against the host immune system. These secretions include nucleic acid-free glycoproteins, called virus-like particles (VLPs) that are produced in the ovarian calyx gland. Results found that VLP-free calyx fluid has the ability to actively suppress host defence reactions, rather than VLPs on the egg surface being solely responsible for the protection of the egg. It wa

Although they are currently effectively controlled by chemicals, sweet potato whiteflies have the potential to once again be a dominant pest in Arizona vegetables. We need to explore alternatives such as biological control so that we are not reliant solely on pesticides. We have been examining dispersal by the whitefly parasitoid Eretmocerus sp. in order to find more effective ways to deploy these agents in the field. We have learned in the laboratory that these wasps are efficient flyers since they are capable of moving into strong winds for more than 30 min. We also now know that most flight

In nature, resources are not uniformly distributed and most often occur aggregated in patches. The profitability of a patch largely depends on the density of resources, the inner composition (types of prey) and the distance from other patches in the habitat. Variability can thus arise between patches but resources may also vary within a patch. In this thesis I have investigated how foragers, such as parasitoids, estimate their resource profitability and explored the impact of variability between resources at different levels: choice of the resource and allocation of time in a patch.

Bibliography: leaves 175-191. Trissolcus basalis (Wollaston) is a solitary endoparasitoid of the eggs of many pentatomid bugs. It is a quasi-gregarious scelenoid and aggressively defends host patches. In the Adelaide (S. Aust.) region its most abundant host is the native horehound bug, Agonoscelis rutila (Fabricius). This study of patch defence draws together important areas of research in parasitoid behavioural ecology, including the theories of adaptive superparasitism, sex ratio decisions, foraging behaviour and contest resolution.

The pine processionary moth (Thaumetopoea spp.), an important defoliator of Pinus spp. in the Mediterranean area, is recently expanding its range in response to climate change and anthropogenic factors. Therefore it's important to outline the way in which this pest can colonize new areas, and to do this molecular markers seem to be the most suitable tools. In the introduction I present some of the molecular markers used in the last years to study ecological and evolutionary problems related to insects.

Consideration of the timing of events indicates that the active component(s) is most likely injected during oviposition and is not related to hatching and growing of the parasitoid larva.

One of the large lineages of parasitic wasps, the Cynipoidea, exhibits three distinctly different life modes. Slightly more than half of the about 3000 species are parasitoids in insect larvae, whereas the remaining species are associated with plants, either as gall inducers or as inquilines (guests feeding on plant tissue in galls). The main focus of this thesis has been to identify morphological changes associated with the shifts between life modes. Particular attention was paid to structures believed to be important in gall initiation. Comparative anatomical studies of the egg, larva and ve

Oilseed rape (Brassica napus (L. )), the second most important arable crop in the UK after cereals, is attacked during the summer by cabbage seed weevil Ceutorhynchus assimilis (Paykull) and brassica pod midge Dasineura =brassicae (Winnertz). In mainland Europe, these two 'pests are known to be attacked by a range of hymenopteran parasitoids but virtually nothing is known about their parasitoids in the UK. This study found that the ectoparasitic Trichomalus perfectus (Walker) (Pteromalidae) was the most abundant species attacking C. assimilis, achieving, in unsprayed crops, levels of parasitis

The behavioural responses of aphid parasitoids (Hymenoptera: Braconidae: Aphidiinae) to aphid sex pheromones were investigated in the laboratory and field. In a wind tunnel bioassay, Aphidius eadyi, Aphidius rhopalosiphi, Diaeretiella rapae, Ephedrus plagiator, Praon myzophagum and Praon volucre responded to the aphid sex pheromone components nepetalactone and nepetalactol. P. myzophagum reared on two different host aphid species showed different responses to combinations of nepetalactone and nepetalactol in the wind tunnel, indicating that long term laboratory rearing may influence parasitoid
