Description:
A chemical toxicity/teratogenicity test was adapted to assess potential adverse affect of a microbial pest control agent on a nontarget fish. eveloping embryos of inland silverside, Menidia beryllina, were exposed to conidiospores or the insect-pathogenic fungus, Beauveria bassiana. dherence of spores to the chorion relate by germination and penetration by the germ tube caused the embryos to rupture, sometimes resulting in death. onidiospores treated with a biological detergent showed significantly less binding (p .01) to embryos than did untreated spores. oth detergent-treated and heat-killed spores failed to cause significant pathogenic responses.
