Residual Activity of Abamectin Against Liriomyza Trifolii (Diptera: Agromyzidae)
AbstractAbamectin was applied to tomato in the field and treated foliage was bioassayed in the laboratory 0, 1, 3, 5 and 7 days after treatment for affects on Liriomyza trifolii (Burgess). Surface residues on leaflets increased mortality of adults only when bioassayed on the day of treatment. Oviposition and larval abundance were reduced even when leaflets were bioassayed 7 days after treatment. Leaf puncturing (stippling) by females was reduced for 3 days after treatment.
