| Stability during storage is a limiting factor in the development and use of bioinsecticides. This study aims to evaluate the compatibility of the entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana with components used in encapsulated formulations and to evaluate shelf-life in formulations with B. bassiana. Sodium alginate and maltodextrin, hemicellulose, and dimethyl sulfoxide solvents were evaluated. Compatibility was evaluated by mixing the components with PDA, and the parameters evaluated were vegetative growth, sporulation and viability. The formulations of fungi were prepared in various concentrations of sodium alginate and then added drop-wise to calcium chloride. To evaluate the stability, formulations were stored at 26.5, 4.0, and... |

| The yellowjacket wasp, Vespula germanica F., is considered a serious pest of productive and recreational activities worldwide. A pathogenicity study was carried out with 29 strains of Metarhizium anisopliae and 30 of Beauveria bassiana against worker and male wasps. Wasps of the same age were fed with liquid sugar baits containing 1 x 10(8) conidia mL-1 suspensions of each strain. The highest mortality and sporulation were obtained with the strains Qu-B941 and Qu-B933 of Beauveria bassiana, reaching 79 and 95% mortality for workers and 66 and 73% for males, respectively. The strains were tested on workers of V. germanica with increasing amounts of bait from 0 to 1 x 10(8) conidia mL-1. The results also showed that 1 x 10(8) conidia mL-1 increased up to 90... |
