Studies were conducted in 1989 and 1990 at Lane, Oklahoma, to evaluate the economic benefits of managing lepidopterous pests of fresh-market cabbage using Bacillus thuringiensis Berliner var. kurstaki, or a pyrethroid insecticide in combination with an economic threshold based on larval density. Marketable cabbage yield and percent head damage were not significantly different among plots spraye...

Cerotoma trifurcata Förster (Coleoptera: Chrysomelidae) and Bean pod mottle virus (Comoviridae) (BPMV) both can reduce yield and seed quality of soybean, Glycine max (L.) Merr. Field experiments were conducted to evaluate the effects of systemic, seed-applied, and foliar-applied insecticides for the management of this pest complex at three locations in central, northeastern, and northwestern Io...

BACKGROUND AND AIMS Integrated vector control especially use of insecticide-treated bed nets have been reported as effective malaria preventive strategies. This study aimed at documenting factors that influence regular use of insecticide-treated nets in under-fives and impact of vector control methods on malaria outcome (severe malaria prevalence and mortality) in under-fives presenting in a te...

Impact of insecticide resistance in Anopheles arabiensis on effectiveness of malaria vector control in Sudan – Hmooda Kafy, National Malaria Control Programme, Sudan The objective of the trial was to assess the impact of insecticide resistance on the effectiveness of malaria vector control in Sudan and to determine the effects of different combinations of vector control intervention combination...

Various insecticide use strategies including rotations, sequential use, and mixtures were evaluated experimentally on Bemisia tabaci (Gennadius) in California and Arizona (U.S.A.) cotton fields. Toxicological responses of adult B. tabaci were measured along with preimaginal densities and cotton yields from plots subjected to different insecticide regimens. Weekly monitoring for susceptibility c...
