Entomologia Experimentalis et Applicata, EarlyView.Developmental photoperiodic exposure (photoacclimation) from egg to adult emergence alters thermal tolerance in Ceratitis capitata. Flies reared under contrasting photoperiods (0:24, 8:16, 14:10, and 24:0 L:D) showed significant shifts in both CTmin and CTmax, whereas adult‐only photoacclimation affected CTmax but not CTmin.

Entomologia Experimentalis et Applicata, EarlyView.Temperature is an important factor to determine the activity of insects. We tested the performance of the non‐native larval parasitoid Leptopilina japonica (Hymenoptera: Figitidae) under realistic climatic conditions to improve understanding about its ongoing spread and seasonal abundance.

Ecological Entomology, EarlyView.Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

Trend analysis of pests and diseases complex in Bt cotton
Journal of Crop Protection, 2015 The significant reduction of bollworm infestation by the implementation of Integrated Pest Management (IPM) in Bt Cotton as a component of IPM led to reduction in bollworm infestation and increase in yield. However, these alterations have brought in many

Journal of Applied Entomology, EarlyView.ABSTRACT Biological control in high tunnel systems can be optimised by matching predator species to seasonal environmental conditions. We evaluated the predatory efficacy of syrphid flies (Toxomerus marginatus (Say), Eupeodes americanus (Fabricius)) and lacewings (Chrysoperla carnea (Stephens), Chrysoperla rufilabris (Burmeister)) across laboratory ...

Responses of Fruit Flies (Diptera: Tephritidae) to Protein Bait Applied at Different Densities
Journal of Applied Entomology, EarlyView.ABSTRACT The effectiveness of odour‐based lures for insects is related to their active space, the air volume around an odour source in which an insect will detect and move towards it. This principle applies to protein baits laced with toxicants that are used as either sprays or stations to suppress pest fruit fly populations.

DIFFUSION OF BT COTTON AND INSECTICIDE USE [PDF]
This study estimated a dynamic logistic model to explain the diffusion Bt cotton in the United States. Regional differences in the speed and extent of Bt cotton adoption were explained by differences in availability of Bt seed adapted to local conditions,
