Activity of spinosad against adults of Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae) is not affected by wheat temperature and moisture
Journal of the Kansas Entomological Society 76 (3), 529-532
Abstract: Spinosad, a commercial bacterial pesticide, was evaluated against adults of the lesser grain borer, Rhyzopertha dominica (F.), on 12.5 or 14.5% moisture wheat stored at 22, 28, and 34°C. Adults of R. dominica were exposed for 14 days to untreated wheat and wheat treated with spinosad at 0.1 and 1 mg (AI)/kg every month for four months. Mortality of adults exposed to untreated wheat ranged from 0 to 39%. All R. dominica adults exposed to spinosad-treated wheat were killed. The activity of spinosad during the four-month test period was not affected by the three temperatures and two moisture levels tested.
