In surveys conducted in Coimbatore district during 2009-10, Okra fruit borers, Earias vittella Fabricius, Earias insulana Boisdual and Helicoverpa armigera (Hübner) were the serious pests causing 50 per cent loss. During the survey, three hymenopteran parasitiods viz., Bassus spp., Brachymeria lasus Walker, Goryphus spp., of the families Braconidae, Chalcididae and Ichneumonidae against Earias spp. and the dipteran parasitoid, Carcelia illota (Tachinidae ) against H. armigera were recorded with 0.00 to 10.00 per cent parasitization.

Temperature is particularly important for ectotherms, including endoparasitoid wasps that develop inside another ectotherm host. In this study, we tested the impact of three temperatures (20 °C, 25 °C and 30 °C) on the host–parasitoid immune interaction using two Drosophila host species (Drosophila melanogaster and D. yakuba) and two parasitoid lines of Leptopilina boulardi. Drosophila’s immune defense against parasitoids consists of the formation of a melanized capsule surrounding the parasitoid egg. To counteract this response, Leptopilina parasitoids rely on the injection of venom during ov

Abstract The sex ratio in the natural population of most Hymenopteran parasitoids is 1 : 1. Females of these parasitoids, however, can regulate the sex of their offspring in response to environmental and biological factors. Under certain circumstances, this may lead to an overproduction of males, which can result in a very negative impact on any control program using these parasitoids. For these reasons, understanding the effect of these factors is very important. In this study, five biological and environmental factors known to affect sex ratio in parasitic Hymenoptera were investigated for A

Herein, the interest is in determining conditions that will maximize parasitoid population productivity when superparasitism varies.

As early as 1844, it was stated that the size of the host may influence the size of parasitoid adults (Ratzeburg 1844) and that parasitoid size may affect fecundity (Salt 1941). Although positive relationships between host and parasitoid body size have been supported in the literature (Tillman and Cate 1993; Heimpel and Rosenheim 1995), this relationship is not universal to all host–parasitoid systems (King 1991; Morse 1994).

Alternative splicing (AS) is a major source of protein diversity in eukaryotes, but less is known about its evolution compared to gene duplication (GD). How AS and GD interact is also largely understudied. By constructing the evolutionary trajectory of the serpin gene PpSerpin-1 (Pteromalus puparum serpin 1) in parasitoids and other insects, we found that both AS and GD jointly contribute to serpin protein diversity. These two processes are negatively correlated and show divergent features in both protein and regulatory sequences. Parasitoid wasps exhibit higher numbers of serpin protein/domai

Insects, the most diverse group of animals, are known to benefit society for a sustainable future. By focusing on the use of natural enemies of pests, including parasitoids and predators, the need for biological pest control for the conservation of agricultural crops has been emphasized. Parasites are organisms that live in the body of another organism and feed on it without killing it, while predators hunt, kill and eat their prey. Parasitoids, on the other hand, live in or on another organism and feed on it, ultimately killing the host. Our study highlights the use of parasitoids to control

Parasitoids are important natural enemies of many agricultural pests. Preserving natural habitats around agricultural fields may support parasitoid populations. However, the success of such an approach depends on the ability of parasitoids to utilize both crop and natural habitats. While these aspects have been studied extensively in temperate regions, very little is known about parasitoid communities in desert agroecosystems. We took one step in this direction by sampling parasitoids in six vineyards and their surrounding natural desert habitat in a hyper-arid region of the Negev Desert Highl

Parasitoid wasps occur within the environment often tracking pest species for food resources to complete their lifecycle. These small wasps are also sensitive to agricultural environments including agrichemicals, habitat availability, and climate. We investigated how the structure of parasitoid communities varied between organic and conventional blueberry systems, and how the communities of these parasitoids varied within field spatial s

Although eggs were absent in the female host, likely because of consumption by parasitoids, distinct corpora lutea (present in parous females) were observed. In the male host, reproductive organs were undamaged. These observations suggest incomplete “parasitic castration” of the host beetle by the parasitoids.

In contrast to symbionts of herbivorous and hematophagous insects, parasitoid symbionts do not provide nutrients. Instead, they are involved in parasitoid reproduction, suppression of host immune responses, and manipulation of the behavior of herbivorous hosts.
