Biologia de Supella longipalpa (Fabricius, 1798) (Dyctioptera: Blateilidae) e Potencial de Contaminação por Fungos e Bactérias em três Bairros na Cidade de Manaus-AM.

Abstract

The blological parameters of the oothecae, nymph and adult stages of Supella longipalpa (Fabricius, 1798) as well as thelr potential for being contaminated by fungi and bactéria, were assessed. Collections were carried out In premises located In three neighborhoods: N.Sra. das Graças, Betânia e Alvorada of the city of Manaus-AM. We obtained 13.6 nymphs per ootheca, with a retentíon period of 39.2 hours and release gap from an ootheca to the other of 5.6 days. Fíve nymph Instars with 70% viability were obtained in the nymph stage. The sex ratio was of 49.6% with a pre-reproductive period of6 days and an average of 6.7 oothecae per female. The whole deveioping cycle lasted 280.29 dias. In the immature and adult stages (male and female) we recorded a higher prevalence of association between the fungi of the genera Penicillium and Aspergilius: gram-negative bactéria with Enterobacter and Klebsiella genera prevailing in the three neighborhoods.
