Cross-resistance responses of Cry1Ac-selected Heliothis virescens (Lepidoptera : Noctuidae) to the Bacillus thuringiensis protein Vip3A
JOURNAL OF ECONOMIC ENTOMOLOGY, 100(1), 180–186.
author keywords: Bacillus thuringiensis; Vip3A; Heliothis virescens; cross-resistance; resistance management
TL;DR:
Results of these experiments demonstrate that cross-resistance is nonexistent between Cry1Ac and Vip3A in H. virescens, and the introduction of VIP3A-producing lines could delayCry1Ac-res resistance evolution in H., if these lines gain a significant share of the market.

Influence of cotton microhabitat on temperature and survival of Trichogramma (Hymenoptera : Trichogrammatidae) within cardboard capsules
ENVIRONMENTAL ENTOMOLOGY, 31(2), 361–366.
author keywords: cotton; microclimate; microhabitat; Trichogramma augmentation; augmentative biological control
TL;DR:
Suitability of the soil surface as a release site for Trichogramma capsules depended significantly on the level of canopy closure, location of capsules relative to the center of rows, and length of time capsules remained in the field before parasitoid emergence, and these factors should be considered when implementing augmentative releases of Trichogramsma wasps in cotton.
