Preventative insecticides reduce seedling injury, but do not increase yield in Bt and non‐Bt corn grown in the mid‐Atlantic

open access: yesPest Management Science, Volume 81, Issue 6, Page 3220-3231, June 2025.
Bacillus thuringiensis (Bt) traits, neonicotinoid seed treatments (NSTs), and in‐furrow pyrethroids (IFPs) can control insect pests of corn, but their target spectrum may be redundant and/or mismatch Mid‐Atlantic pest pressure. Across 9 site‐years insecticide treatments reduced pest damage and sometimes increased plant stand, but never improved yield ...

Cover crops dismantle keystone ant/aphid mutualisms to enhance insect pest suppression and weed biocontrol

open access: yesAgricultural and Forest Entomology, Volume 27, Issue 2, Page 294-303, May 2025.
Abstract Cover crops are multifunctional tools that mitigate environmental impacts of agriculture, enhance resilience to weather extremes and suppress weeds and arthropod pests. Cover crops provide non‐crop food and habitat resources that attract natural enemies of pests, but their outcomes for pest management are less clear in regions where keystone ...

Tomato Defenses Under Stress: The Impact of Salinity on Direct Defenses Against Insect Herbivores

open access: yesPlant, Cell &Environment, Volume 48, Issue 5, Page 3647-3659, May 2025.
ABSTRACT Abiotic stressors, such as salt stress, can reduce crop productivity, and when combined with biotic pressures, such as insect herbivory, can exacerbate yield losses. However, salinity‐induced changes to plant quality and defenses can in turn affect insect herbivores feeding on plants.
