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.

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.

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 ...

Evaluation of diverse elite and landrace maize lines for testcross hybrid performance and combining ability under low and high phosphorus fertilization regimes

Crop Science, Volume 66, Issue 1, January/February 2026.
Abstract In the context of over‐fertilization, especially of phosphorus (P), the debate about the usefulness of applying starter fertilization to maize (Zea mays L.) must be revisited. One solution is to breed crops with an enhanced phosphorus use efficiency, which require less fertilizer yet are high‐yielding.

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.

Host and symbiont genetic contributions to fitness in a Trichogramma-Wolbachia symbiosis. [PDF]

, 2018
The fitness effects associated with Wolbachia infection have wide-ranging ecological and evolutionary consequences for host species. How these effects are modulated by the relative influence of host and Wolbachia genomes has been described as a balancing

Native insect species should be selected for classroom rearings

Insect Conservation and Diversity, Volume 19, Issue 1, Page 1-10, January 2026.
Rearing insects in the school classroom can build positive attitudes towards insects among schoolchildren, which is becoming increasingly important as insect populations decline. Identified frequent use of non‐native insect species, raising environmental and ethical concerns after classroom rearing ends.

Comparative Genomics of the Endosymbiont Cardinium Causing Reproductive Manipulation in Encarsia Parasitoid Wasps

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
We assembled four Cardinium hertigii draft genomes: cEina3 causes cytoplasmic incompatibility, cEhis1 induces parthenogenesis, cEper2 is associated with parthenogenesis, and cEina2 infects asymptomatically. All four strains are closely related and hosted by Encarsia parasitoid wasps, but key differences exist, including their metabolic potential and ...
