Ants do not prey upon an extrafloral‐nectar‐feeding predatory mite

open access: yesEcological Entomology, EarlyView.
The predatory mite Amblyseius herbicolus is an important natural enemy of various crop pests and occurs in agroforestry coffee systems, where it feeds on the extrafloral nectar of Inga trees. Because extrafloral nectaries are often vigorously defended by ants, we tested whether ants would attack and kill the mites near nectaries.

Salicylate plant defences reduce aphid nutritional quality and increase predator consumption

open access: yesEcological Entomology, EarlyView.
Salicylic acid‐induced defences diminish Macrosiphum euphorbiae performance and nutritional quality by reducing body protein and lipid content. Ladybird beetle predators (Hippodamia convergens) consumed more low‐quality aphids compared to high‐quality aphids, exhibiting compensatory feeding response to nutrient‐deficient p prey.

No genetic differentiation among populations up to 300 km apart in three species of carrion beetles

open access: yesEcological Entomology, EarlyView.
Habitat fragmentation threatens biodiversity by disrupting gene flow; understanding species' dispersal abilities is key to determining whether they are limited by habitat or mobility. Carrion beetles show no significant population genetic structure across up to 320 km, indicating high dispersal ability and unrestricted gene flow.
