Anomalous latitudinal gradients in parasitoid wasp diversity—Hotspots in regions with larger temperature range

open access: yesJournal of Animal Ecology, Volume 94, Issue 3, Page 410-422, March 2025.
Using the largest georeferenced molecular dataset for ichneumonoid parasitoid wasps, we implemented a macrogenetics approach to examine latitudinal patterns and predictors of intraspecific genetic diversity and explain the global distribution of genetic diversity in this group.

Cereal aphid species: their natural enemies and efficiency of Lysiphlebus testaceipes (Cresson, 1880) to control Rhopalosiphum maidis (Fitch, 1856)

open access: yesEPPO Bulletin, Volume 54, Issue 3, Page 369-380, December 2024.
Abstract Cereal grains both for human consumption and animal feed are an essential component of global food systems. However, during production they are often targeted by various pest insects, including aphids. A survey was carried out from 2017 to 2021 in six cereal production sites in Tunisia to evaluate aphid diversity and identify natural enemies ...

Density‐dependence and competition between Tranosema rostrale and Elachertus cacoeciae, two parasitoids of the spruce budworm

open access: yesEntomologia Experimentalis et Applicata, Volume 172, Issue 6, Page 533-543, June 2024.
The interactions between two common parasitoid species (Hymenoptera) of the spruce budworm, Choristoneura fumiferana (Lepidoptera: Tortricidae), were investigated during the low‐density period between outbreaks using data collected through field‐implanted larvae in two sites over a 35‐year period.

Fewer pests and more ecosystem service‐providing arthropods in shady African cocoa farms: Insights from a data integration study

open access: yesJournal of Applied Ecology, Volume 61, Issue 2, Page 304-315, February 2024.
To achieve lower pest burdens and higher abundances of potential pollinators and natural enemies, African cocoa farms should maintain a dense canopy of shade trees. The current shift towards high‐intensity cocoa farming in Africa could result in long‐term losses due to pest infestations and loss of arthropod‐mediated ecosystem services.
