Abstract

The relative toxicity of different compounds against the seychellarum mealybug, Icerya seychellarum (Westwood) (Hemiptera: Monophlebidae) and the vedalia beetle, Rodalia cardinalis (Mulsant) (Coleoptera: Coccinellidae) were studied on mango leaves under laboratory conditions. The obtained data indicated that different compounds (Biofly, NeemAzal and Super Mesrona oil) gave medium effects on nymphs, and adult females of I. seychellarum and immature and mature stages of their predator R.cardinalis, compared with Malathion which gave highly effects on the mealybug and its predator using direct exposure technique.
