Molecular identification of Trichogramma Westwood, 1833 species as egg parasitoids of Ostrinia nubilalis (Hübner, 1796) in corn production areas of Sakarya province in Türkiye (Insecta: Lepidoptera, Hymenoptera)

SHILAP
The study focuses on using ITS2 sequences from rDNA for systematic studies of Trichogramma Westwood, 1833 species. ITS2 sequences have shown to be reliable in distinguishing Trichogramma species.

Biological control of fall armyworm Spodoptera frugiperda (JE Smith) using egg parasitoids, Trichogramma species (Hymenoptera: Trichogrammatidae): a review

Egyptian Journal of Biological Pest Control, 2023
Background Fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is an invasive pest that can cause serious crop loss to various important food crops and risk to global food security.

Generation cycles in experimental populations of a multivoltine insect

Journal of Animal Ecology, EarlyView.
Although theory suggests various mechanisms by which environmental and ecological factors may drive generational fluctuations, our field‐cage experiment is the first to demonstrate how internal dynamics and external disturbances jointly produce synchronised, large‐scale outbreak cycles.

Impact of Short-Term High Temperature on <i>Microplitis manilae</i> (Hymenoptera: Braconidae) Survival, Fecundity and Progeny Development. [PDF]

Ecol Evol
This study reveals the effects of short‐term high‐temperature stress on the survival, reproduction, and progeny development of M. manilae. It provides a theoretical basis for understanding the biological evolution mechanism of M. manilae in response to thermal stress and the biological control of pests by M.

Host age selection behaviour of Trichogramma aurosum Sugonjaev & Sorokina (Hymenoptera: Trichogrammatidae) [PDF]

, 2004
Host age selection in several German strains of Trichogramma aurosum Sugonjaev & Sorokina was examined in laboratory choice tests under direct observation for 90 min., in order to select candidate strains for attempts at controlling the codling moth ...

A New Experimental Setup to Study the Olfactory Behaviour of Trichogramma Egg Parasitoids

Entomologia Experimentalis et Applicata, EarlyView.
We developed an experimental setup to assess odor‐induced egg‐laying behavior in tiny egg‐parasitoid wasps. This Y‐shaped olfactometer, coupled with an AI‐based image‐recognition model, automatically quantifies egg parasitism by Trichogramma wasps. Olfactory‐driven egg‐laying preferences were analyzed using Bayesian inference.

Comparative genomics of the miniature wasp and pest control agent Trichogramma pretiosum

BMC Biology, 2018
Background Trichogrammatids are minute parasitoid wasps that develop within other insect eggs. They are less than half a millimeter long, smaller than some protozoans.

Rapid molecular identification of Trichogramma (Hymenoptera: Trichogrammatidae) parasitizing the eggs of the European corn borer, Ostrinia nubilalis (Lepidoptera: Crambidae) in Serbia

Egyptian Journal of Biological Pest Control, 2021
Background The European corn borer (ECB), Ostrinia nubilalis (Hübner, 1796) (Lepidoptera: Crambidae), is the major pest of maize (Zea mays Linnaeus, 1753) in Serbia.

Impact of Host and Food Availability on Life‐History Traits in Six Egg Parasitoid Species of the Genus Trichogramma

Entomologia Experimentalis et Applicata, EarlyView.
In this study we measured the impact of access to sugar and hosts on the longevity and fecundity of six Trichogramma species: T. cacoeciae, T. chilonis, T. minutum, T. leptoparameron, T. pintoi and T. sibericum. The impact of food differed among species, but there was a general tendency of increased life expectancy and potential fecundity with sugar ...
