A Fly in the Ointment? Non‐Target Fly Pest Benefits From Reduction in Ivermectin During Targeted Selective Treatment

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Targeted Selective Treatment (TST) can reduce the rate of resistance development in livestock gastrointestinal nematodes but can also reduce the effects of anthelmintics on non‐target organisms. Most studies of non‐target anthelmintic effects focus on beneficial species.

The effects of Bacillus thuringiensis var. israelensis (Bti) on tropical stream food webs vary between two consecutive dry seasons

open access: yesInsect Conservation and Diversity, EarlyView.
Bti application altered tropical stream food‐web structure through changes in macroinvertebrate functional feeding groups. Collector‐filterers and predators showed context‐dependent responses, with clearer direct and indirect effects detected in 2016, the year with higher rainfall.
