BEHAVIOR AND CYTOLOGICAL ASPECTS OF BEAUVERIA BASSIANA AFTER PASSAGE IN THE EGG, LARVAE AND ADULT PHASE OF CHRYSOMYA ALBICEPS

ABSTRACT

The objective this research was to evaluate the behavior of Beuveria bassiana Balsamo Vuillemin fungus reisolated from different phases of development of Chrysomya albiceps. The fungus B. bassiana was isolated originally from Castnia licus Drury (Lepidoptera: Castniidae), and kept at the Culture Collection (Micoteca-URM) of the Department of Mycology of the Universidade Federal de Pernambuco, under the access number 3,447. The experiment was carried out under artificial conditions at 60 ± 10% relative humidity and 27 ± 1^o C. The percentile of germination was elevated, with the largest index observed in the reisolate from the larval phase; the radial growth in the interval of stipulated time was satisfactory, the conidia number on the 12th day for the reisolate from the adult phase was larger than that for the reisolate from the egg phase. The number of colonies of all the reisolates was higher than that of the control. Differences were not observed in the cytological aspects of the life cycle of B. bassiana after passage in eggs, larvae and adults.
