The revival of tribes: An analysis of Platystomatidae (Diptera, Tephritoidea) phylogeny based on external morphological traits

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
First comprehensive phylogenetic hypothesis for the fly family Platystomatidae, based on 194 morphological characters, confirming the monophyly of its four traditional subfamilies. Illustrations of the external and internal morphology of nearly all genera of Platystomatidae are presented here; in addition, a new genus, Trapheroplatystoma gen. nov., and

Experimental Disentangling of the Effects of Initial Population Size and Resource Availability on Weevil Population Dynamics

open access: yesEntomologia Experimentalis et Applicata, Volume 173, Issue 12, Page 1278-1284, December 2025.
Initial population size and resource availability are key factors regulating population dynamics, with growth rates typically declining as populations increase but rising with greater resources. In maize weevils, however, we found an unexpected negative effect of resource availability on intrinsic growth rates, contrary to conventional expectations. We
