Abstract

JARAMILLO R, GLORIA ISABEL  and  GONZALEZ O, RANULPO. Secoridary kill of Periplaneta americana (Blattodea: blattidae) adults through cannibalism of specimens Rilled by imidacloprid . Rev. Colomb. Entomol. [online]. 2005, vol.31, n.1, pp.05-08. ISSN 0120-0488.

Adults of Periplaneta americana L. were evaluated under laboratory conditions to verify indirect poisoning (by cannibalism) through action of a toxic bait base on imidacloprid (2,15%). The mortality caused by direct and indirect ingestion (througfl cannibalism) of the bait varied between 97-IOO%. The average lethal time of specimens that consumed the bait directly was less (11,012 h) and significantly different than those that consumed it indirectly (65,88-96,70 h). Sirnilarly, the average lethal knock down time of specimens that directly ingested the bait was less (0,07 h) and significantly different from average knocK down times of those that acquired it indirectly, 7,98 h for those that ingested the toxin of an individual poisoned 4 h before the tests and 10,23 h from those that ingested the toxin of an individual poisoned 24 h before the tests. The results obtained support the hypothesis that the imidacloprid molecule is able to affect specimens in an indirect way (through cannibalism).
