Selectivity of some insecticides/acaricides 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 acaricide fenbutatin-oxide, at the rates usually recommended for crop protection in the field. Adults mortality were evaluated after 96 hours to determine the selectivity of these compounds to the predator. The effects on the fecundity of the adults and viability of the eggs were evaluated until 30 days after the treatments. The results showed that fenitrothion, fenvalerate and fenpropathrin at the higher rate were highly toxic, with a very high mortality. Fenbutatin-oxide was not toxic to adults of the predator.
