Abstract:
... The total of 22 Baculovirus isolates surveyed in different corn producing regions in Brazil were used against fall armyworm, Spodoptera frugiperda (J.E. Smith). The viruses were purified and their suspensions were used to feed fall armyworm larvae from 4th and 5th instar. The mortality rate was checked daily and the infected larvae were frost after death, what generally occurred between the 5th an ...

Abstract:
... The action of Metarhizium anisopliae var. anisopliae and Metarhizium anisopliae var. acridum on the mound termite Nasutitermes coxipoensis (Holmgren) and the conidia production on dead insects were studied in laboratory. Infective doses were determined through direct contact of the insects with the fungi cultures with 12 days of growth followed by conidia quantification in Neubauer camera. The dos ...

Beauveria bassiana; entomopathogenic fungi; virulence; provenance; biological control agents; fungal spores; sporulation; insect control; biological control; integrated pest management; Hypothenemus hampei; insect pests; plant pests; mortality
Abstract:
... Hypothenemus hampei (Ferrari) (Coffee Berry Borer) is one of the most important coffee pests. Its control is carried out mainly using synthetic chemical products, which contaminate the environment, food and farmers. The entomopathogenic fungus Beauveria bassiana is a natural enemy of coffee berry borer and presents potential for biological control. With the objective to select strains of B. bassia ...

Abstract:
... The influence of temperature on the development rate of the entomopathogenic fungus Nomuraea rileyi (Farlow) Samson in Anticarsia gemmatalis (Hubner) 3rd-instar larvae was studied under constant temperature regimes. A non linear model was used to describe temperature-dependent vegetative and reproductive development rates of the fungus. The temperature required to reach the highest vegetative deve ...
