The toxicity of abamectin to Liriamyza trifalii (Burgess)was determined with a leaf-dip technique using infested cowpea leaves. The LC50, and LC90 for the larval stage were 0.377 and 1.473 ppm, respectively. The LC50 and LC90 for the larval and pupal stages combined were 0.202 and 0.724 ppm, respectively. The relationship of concentration (x) to percentage of aberrant puparial forms (y) was linear through 0.65 ppm (y = 96.34x + 5.55, R2 = 0.90). Very few (0.5%) adults emerged from the aberrant puparial forms.
