SELECTIVITY OF SOME INSECTICIDES ACARICID ES TO ADULTS OF CERAEOCHRYSA-CUBANA (HAGEN, 1861) (NEUROPTERA, CHRYSOPIDAE) IN THE LABORATORY/

Adults of the predator Ceraeochrysa cubana (Hagen, 1861) were sprayed with the fenpropathrin, fenvalerate, fenitrothion and with the acarici de fenbutatin-oxide, at the rates usually recommended for crop protect ion in the field. Adults mortality were evaluated after 96 hours to de termine the selectivity of these compounds to the predator. The effect s on the fecundity of the adults and viability of the eggs were evalua ted until 30 days after the treatments. The results showed that fenitr othion, fenvalerate and fenpropathrin at the higher rate were highly t oxic, with a very high mortality. Fenbutatin-oxide was not toxic to ad ults of the predator.
