C. de  aSusceptibility of non-target invertebrates to Brazilian microbial pest control agents.h[electronic resource]  c2011  aAbstract: Microbial pest control agents or entomopathogens have been considered an interesting alternative to use instead of chemical insecticides. Knowledge of ecotoxicity data is very important to predict the hazard of any product released in the environment and subsidize the regulation of these products by governmental agencies. In the present study four new Brazilian strains of Bacillus and one fungus were tested to evaluate their acute toxicity to the microcrustacean Daphnia similis, the snail Biomphalaria glabrata and the dung beetle Digitonthophagus gazella. The microcrustaceans and the snails were exposed to entomopathogens in synthetic softwater and the beetles were exposed directly in cattle dung. Obtained data reveal low susceptibility of the non-target species to tested microorganisms, with lethal concentrations being observed only at much higher concentrations than that effective against target insects. These results show that the tested strains are selective in their action mode and seem to be non-hazardous to non-target species.  aBacillus sphaericus  aBiological control agents  aDaphnia magna  aToxicity  aBacillus thuringiensis  aBiomphalaria glabrata  aControle biológico  aToxidez  aDiginthontophagus gazella  aSporothrix insectorum1 aMUNIZ, D.
