Physiological Host Range of the Tachinid Istocheta aldrichi, a Potential Biological Control Agent for the Japanese Beetle in Europe

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
This study provides the first laboratory assessment of the physiological host range of Istocheta aldrichi, a candidate biological control agent for Popillia japonica in Europe. In sequential no‐choice tests with 14 European scarab beetles, the parasitoid oviposited on six species but successfully developed only in the two Rutelinae Anomala vitis and ...

open access: yesAustral Entomology, Volume 65, Issue 4, November 2026.
ABSTRACT Here, we review the generic classification of Eucanthini, resulting in the redefinition of Eucanthus Westwood, 1848 and erection of two new genera. Under this new framework, Eucanthus is restricted to six North American species, while two monotypic genera are described from the Southern Hemisphere: Antoniocanthus gen. nov.

When Resources Become Limited: Trophic Niches Shift From Generalism to Specialization in Dung Beetles (Coleoptera: Scarabaeinae)

open access: yesAustral Ecology, Volume 51, Issue 9, September 2026.
ABSTRACT Resource availability and predictability can shape trophic organization in ecological communities. In livestock pastures, cattle dung represents a highly abundant and predictable trophic subsidy for dung beetles, potentially promoting generalist foraging strategies. Here, we test how cattle exclusion affects trophic organization in dung beetle
