Inheritance of an oviposition behavior by an egg parasitoid [PDF]
A quantitative genetic study revealed genetic and environmental sources of variance in percentage parasitism of European corn borer egg masses and secondary sex ratios by Trichogramma nubilale. Full and half-sib groups of T. nubilale were obtained from a nested mating design, which permitted the partitioning of the variance of T. nubilale parasitism of

The effect of temperature on host patch exploitation by an egg parasitoid. [PDF]
The effect of temperature during host patch exploitation by parasitoids remains poorly understood, despite its importance on female reproductive success. Under laboratory conditions, we explored the behaviour ofAnaphes listronoti, an egg parasitoid of the carrot weevil,Listronotus oregonensis, when foraging on a host patch at five temperatures ...

The complete mitochondrial genome of an egg parasitoid (Trichogramma chilonis). [PDF]
Trichogramma chilonis Ishii is an important natural enemy of several lepidopterous pests on crops. In this study, we sequenced the complete mitochondrial genome of T. chilonis (GenBank accession number MW789210). The length of the complete mitochondrial genome was 16,147 bp, containing 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a non ...

Egg parasitoid exploitation of plant volatiles induced by single or concurrent attack of a zoophytophagous predator and an invasive phytophagous pest. [PDF]
Zoophytophagous insect predators can induce physiological responses in plants by activating defence signalling pathways, but whether plants can respond to facultative phytophagy by recruiting natural enemies remains to be investigated.

Biological control in French Guiana, Guadeloupe and Martinique [PDF]
Several biological control agents have been introduced successfully in Guyana, and / or Guadeloupe and Martinique: three tachinid dipterans and one hymenopteran for control of sugarcane borers, a ladybird and a hymenopteran parasitoid against the pink ...

Comparing and contrasting development and reproductive strategies in the pupal hyperparasitoids Lysibia nana and Gelis agilis (Hymenoptera: Ichneumonidae) [PDF]
In most animals, the optimal phenotype is determined by trade-offs in life-history traits. Here, I compare development and reproductive strategies in two species of solitary secondary hyperparasitoids, Lysibia nana and Gelis agilis, attacking pre-pupae ...

The Significance of Background Odour for an Egg Parasitoid to Detect Plants with Host Eggs [PDF]
Scots pine has been shown to produce a volatile bouquet that attracts egg parasitoids in response to oviposition of the herbivorous sawfly Diprion pini. Previous analyses of headspace volatiles of oviposition-induced pine twigs revealed only quantitative changes; in particular, the sesquiterpene (E)-beta-farnesene was emitted in significantly higher ...

Egg Collection for Nasonia (Parasitoid Wasp) [PDF]
INTRODUCTIONNasonia is a complex of four closely related species of wasps with several features that make it an excellent system for a variety of genetic studies. These include a short generation time, ease of rearing, interfertile species, visible and molecular markers, and a sequenced genome.
