The effect of temperature on host patch exploitation by an egg parasitoid. [PDF]
PLoS One, 2021 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 ...

An Egg Parasitoid Efficiently Exploits Cues From a Coevolved Host But Not Those From a Novel Host [PDF]
Frontiers in Physiology, 2019 Egg parasitoids have evolved adaptations to exploit host-associated cues, especially oviposition-induced plant volatiles and odors of gravid females, when foraging for hosts.

The remarkable biology of a new species of Gelis Thunberg, 1827 (Ichneumonidae, Phygadeuontinae), a solitary endoparasitoid of fresh eggs of Timarcha (Coleoptera, Chrysomelidae) [PDF]
Journal of Hymenoptera Research, 2021 A new species, Gelis timarchae Schwarz, Shaw & Kan, is figured and described from specimens reared as a solitary endoparasitoid of fresh eggs of Timarcha nicaeensis in the south of France.

Insects, 2022 The mass rearing of hymenopteran egg parasitoids requires an abundant supply of host eggs. The onset of reproductive diapause and subsequent decline in egg production poses a challenge for parasitoid rearing when using host colonies augmented by field ...

Chemical Cues in Tritrophic Interaction on Biocontrol of Insect Pest [PDF]
Journal of Pure and Applied Chemistry Research, 2017 Tritrophic interaction among host plant-herbivore-parasitoid involves chemical cues. The infested plant by herbivores has been reacted to produce volatiles which is a cue used by the herbivore parasitoids for host location.

Inheritance of an oviposition behavior by an egg parasitoid [PDF]
Heredity, 2002 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

Insects, 2023 Parasitoids forage for hosts in dynamic ecosystems and generally have a short period of time to access hosts. The current study examined the optimal reproductive attributes of two egg parasitoids, Paratelenomus saccharalis Dodd (Hymenoptera ...
