Pernethrin has been recommended for use im predator exclusion studies of Amblyseius limonicus Garman & McGregor (formerly in Typholodromalus), an important predator of tetranychid cassava(Manihot esculenta Crantz) pests: green mite, Mononychellus progresivus Doreste, and twospotted spider mite, Tentrancychus urticae Koch. Among criteria for a chemical exclusion agebt are selective toxicity and lack of side effects such enhanced pest fecundity, stimluation of plant growth, or improvement of host plant nutritional quality. Laboratory and field test providd no evidence for phytostimulation, change in cassava nutritional quality, or increased spider mite fecundity; however, abundance of nontarget arthropods was significantly reduced in permethrin-treated field plots. A possible repelleney effect of permethrin on M. progresivus was suggested under laboratory conditions. Implications of repellency and lowered abundance of nontarget species for field use of permethrin as a predator exclusion agent are discussed. |
