Strong diel variation in the activity of insect taxa sampled by Malaise traps

open access: yesEcological Entomology, EarlyView.
Malaise traps sampled different communities during mornings (06:00–12:00), afternoons (12:00–16:00), evenings (18:00–22:00), and nights (22:00–06:00), highlighting the difference in diel rhythm between taxa. The highest diversity and abundance of insects were found during afternoons, the lowest diversity during night, and the lowest abundance during ...

Floral resource strips enhance parasitoid abundance and diversity in apple orchards and promote agroecological advances in a South African biosphere reserve

open access: yesInsect Conservation and Diversity, EarlyView.
Floral resource strips within apple orchards increased parasitoid abundance and influenced community composition, enhancing local biodiversity in the Kogelberg Biosphere Reserve's transition zone. Ruderal and natural fynbos habitats supported higher parasitoid richness and abundance, emphasising the importance of conserving semi‐natural habitats ...

A Parasitoid of Aphids Manipulates Host Mummification Site, With Effects on Survival but Not Hyperparasitism

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
Parasitoid wasps can manipulate host behavior to enhance their own survival. Here we find that a parasitoid of aphids, Aphelinus chaonia, induces aphids to move to the leaf axil or leave the plant prior to pupation. This seems to have no effect on hyperparasitism, but mummy location may nevertheless impact parasitoid survival.
