The ecotoxicological impact of the insecticide cartap, extracted from
the marine polychaete Lumbrinereis spp., was evaluated on
three representative organisms of the animal community. The
microcrustaceans Moina macrocopa (Sars) (freshwater
environment) and Porcellio laevis Latreille (terrestrial
environment), and also the parasitoid microhymenopterans Muscidifurax
raptorrellus Kogan & Legner (aerial environment) were used
as side effect organisms on different models of acute bioassays at 24
and 48 h of exposure to determine the toxicological impact of cartap.
The LD 50 (mean lethal dose) of P. laevis and the LC 50 (mean lethal
concentration) of M. macrocopa and M. raptorrellus , allowed the
calculation of the risk quotients (RQs) for the environmental risk
assessment (ERA) of this product in the ecosystem. The analysis of ERA
and LT 50 (mean lethal time) indicated a moderate impact for cartap on
the environment
