| Blattella germanica (Dictyoptera: Blattellidae) es la especie más importante de las cucarachas sinantrópicas en el mundo. En este trabajo se evaluó la patogenicidad de aislamientos de Metarhizium anisopliae, M. pingshaense y Beauveria bassiana en ninfas y adultos de B. germanica. Para ofrecer una alternativa al uso de insecticidas en el manejo de B germanica, se desarrolló una formulación de cebo en polvo y pellet. Se determinó la preferencia de adultos de esta cucaracha, a diferentes dosis de azúcar glas (0.125, 0.25, 0.5, 0.75M) como fagoestimulante y se evaluó la compatibilidad del ácido bórico con los hongos M anisopliae y B bassiana en estos cebos. Finalmente, se evaluó vía oral, la virulencia de cebos formulados con azúcar glas 0.5 M, ácido bórico... |

| Microbial insecticides for cockroach control, such as those containing entomopathogenic fungi, may be an alternative to reduce contamination by chemicals in housing and food storage environments. Virulence of isolate ESALQ1037 belonging to the Metarhizium anisopliae complex against nymphs and adults of Blattella germanica (L.), and its infectivity following exposure of insects to a contaminated surface or to M. anisopliae-bait were determined under laboratory conditions. Estimated LD50 15 d following topical inoculation was 2.69 x 10(5) conidia per adult, whereas for nymphs the maximum mortality was lower than 50%. Baits amended with M. anisopliae conidia had no repellent effect on targets; adult mortality was inferior to 25%, and nymphs were not... |
