Egg parasitoids of Arboridia apicalis (Nawa, 1913) (Hemiptera, Cicadellidae), a leafhopper pest of grapevines in Japan, with description of a new species of Anagrus Haliday, 1833 (Hymenoptera, Mymaridae) [PDF]

ZooKeys, 2020
Several species of egg parasitoids (Hymenoptera: Mymaridae and Trichogrammatidae) of the leafhopper pest of grapevines in Japan, Arboridia (Arboridia) apicalis (Nawa) (Hemiptera, Cicadellidae), were reared and identified for the first time.

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

Insect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Optimisation of Drop‐Sheet Sampling in Macadamia (Macadamia integrifolia) Orchards: An Optimised Method for Monitoring Insect Ecology

Austral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT Understanding orchard arthropod populations is a critical element of making strategic decisions regarding pest management. Therefore, it is paramount for farmers and crop consultants to use appropriate survey methods that provide a representative sample of orchard insect ecology. Currently, macadamia (Macadamia integrifolia) industry arthropod

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

Entomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 968-974, August 2026.
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.

A taxonomic description of three new Ufens species (Hymenoptera: Trichogrammatidae) from India

Journal of Asia-Pacific Biodiversity
The cosmopolitan genus Ufens primarily parasitizes hemipteran eggs and is common in temperate and semi-arid regions such as Asia, the southwestern U.S., and Australia. This study describes three new species from India: U. garhwalensis, U.
