Arrhythmic adult ecdysis but rhythmic emergence from the host chorion in Trichogramma embryophagum (Hymenoptera: Trichogrammatidae)

European Journal of Entomology, 2008
In many insect species with a pupa covered by various "shells" (puparium, host remains, etc.) pupal-adult ecdysis and emergence to the open air represent two discrete steps.

Design of a trichogramma balls UAV delivery system and quality analysis of delivery operation

Frontiers in Plant Science, 2023
The field boundaries in our country are complex. In attempts to control pests via trichogramma-dominated biological control, the long-term practice of manual trichogramma release has resulted in low control efficiency, thereby impeding sustainable ...

Effect of temperature on the reproduction and development of Trichogramma buesi (Hymenoptera: Trichogrammatidae)

European Journal of Entomology, 2009
At emergence females of Trichogramma had a lot of mature eggs in their ovaries, but some delayed parasitization or refused to parasitize a laboratory host.

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.

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.
