This study was carried out under laboratory conditions to determine some parameters related to the selectivity of avermectin-B1 (MK-936) to Trichogramma demoraesi, parasite of eggs of several especies of agricultural pests. This compound at 1.8% EC formulation and rates of 0.1; 0.2; 0.4 and 0.8 ml/l have not affected the pre-imaginal development of the parasite before its emergence from the parasited eggs. The same situation have occured when high rates of the insecticides such as 8.0 ml/l was applied. No significant mortality was observed when the adult parasites oviposited in insecticide previously treated eggs of Anagasta kuehniella (Zeller, 1879) (Lep., Pyralidae). Contact action of avermectin-B1 applied inside the rearing vials was not...
