Abstract:Laboratory tests were conducted to evaluate the effect of simultaneous and sequential treatments of cytoplasmic or nuclear polyhedrosis viruses and a synthetic pyrethroid, permethrin (Ambush),on the larvae of Euxoa scandens (Riley). A significant increase in total mortality occurred when permethrin was applied to larvae previously infected for a period of 4 to 7 days with virus. Comparisons of infected and noninfected larvae indicated that the toxicity of permethrin increased by l.51-fold for CPV-infected larvae after 6 days of infection and 4.18-fold for NPV infected larvae.
