Novel adult feeding disruption test (FDT) to detect insecticide resistance of lepidopteran pests in cotton
Autor: Ana R. Cabrera, R. Michael Roe, J. R. Bradley, B van Kretschmar
Publikováno v: Pest Management Science. 69:652-660
BACKGROUND Resistance monitoring is an important aspect of insect resistance management and the preservation of insecticide efficacy. The adult vial test (AVT) is most often used for resistance monitoring for a variety of insects. A potential alterna

Effects of Vegetated Field Borders on Arthropods in Cotton Fields in Eastern North Carolina
Autor: Clyde E. Sorenson, Randy Outward, J. R. Bradley
Publikováno v: Journal of Insect Science
The influence, if any, of 5m wide, feral, herbaceous field borders on pest and beneficial arthropods in commercial cotton, Gossypium hirsutum (L.) (Malvales: Malvaceae), fields was measured through a variety of sampling techniques over three years. I
