Neemseed powder, as a protectant for dried Tilapia Fish against Dermestes maculatus Degeer infestation
Published online by Cambridge University Press: 19 September 2011
Abstract
Various stages of Dermestes maculatus DeGeer were placed in specimen jars in contact with dried Tilapia fish treated separately with 0.25, 0.50, 1 and 2 g of neemseed powder per 25 g of fish. Neem powder significantly inhibited oviposition and killed the adults. Neem has no ovicidal action, but incubation period was prolonged. In treated fish, larvae did not develop beyond the second instar and 93 % of larvae died by day 30. Minimal frass was produced in treated fish. The aesthetic attractiveness of the fish was high.
Résumé
Plusieur stades de Dermestes maculatus DeGeer furent mis dans un recipient echantillon en contact avec du-poisson Tilapia seche et separement traite avec 0.25, 0.50, 1 et 2 grames de la pouder de “graine de neem” par 25 g de-poisson. Il fut observeque i'oviposition etait inhibee et que les adultes furent tue. La poudre de “graine de neem” n'avait acun action ovicide sur les insectes main la periode d'incubation fut prolongé. Les larves ne gran-dirent pas au delà dudeuxie-me instar 95% des larves furent tue au 30 jours. Le traitement posterieur de poisson “frass” de production etait minimal chez les poissons traite. L'attirance esthetique du poisson était éleve.
