Genome-Wide Identification and Comparative Characterization of Chemosensory Gene Families in Two Phthorimaea Pests

open access: yesInsects
Insects rely on their olfactory systems for host finding, mate choice, and oviposition. These odor-guided behaviors are mediated by the peripheral chemosensory system.

Chalcosicya maya n. sp, a new Mexican species (Coleoptera: Chrysomelidae: Eumoplinae) and its implications for morphology and biogeography [PDF]

open access: yes, 2012
Chalcosicya maya, new species, (Coleoptera: Chrysomelidae: Eumolpinae) is described and the species key of Blake (1951) is modified to accommodate it. This is the first known mainland species of this previously Antillean genus.

A roadmap to key traits of invasive Drosophilidae

open access: yesBiological Reviews, EarlyView.
ABSTRACT Biological invasions have intensified in recent decades, mostly driven by international trade and travel, raising significant concerns, particularly regarding insect pests. Once non‐native species establish, they can disrupt natural ecosystem stability, undermine agroecosystem sustainability and cause substantial economic losses.

A Comparative Functional Approach to the Host Detection Behaviour of Parasitic Wasps. 1. A Qualitative Study on Eucoilidae and Alysiinae [PDF]

open access: yes, 1985
We studied host detection behaviour in Alysiinae (Braconidae; Ichneumonoidea) and Eucoilidae (Cynipoidea), the larvae of which are endoparasitoids of fly larvae and in- vestigated whether this behaviour is determined by their descent or can be considered
