Several insect viruses, specially those belonging to the family Baculoviridae, have been developed as microbial insecticides in different countries of the world in lieu of chemical insecticides, due to their virulence to their hosts, specificity, and safety to vertebrates, including man. The largest program, in terms of treated area, is probably the one developed in Brazil by Embrapa-CNPSo for control of the velvetbean caterpillar, Anticarsia gemmatalis, the most serious defoliator of soybeans in the country. The program, initiated in 1979, was based on research related to virus specifity, persistence on leaves and the soil, establishment of thresholds for virus application (in terms of number and age composition of larvae), field dosages, interaction with predators (virus dissemination) and the naturally ocUrring entomogenous fungus Nomuraea rileyi, and establishment of methodology for virus mass production on laboratory reared A. gemmatalis larvae. Laboratories for virus mass production were implemented in different soybean producing regions, in some research institutions, as well as farmer cooperatives, with the purpose of distributing the virus to farmers, who were instructed to multiply it at field level for treatment of larger areas with crude preparations of the pathogen. A simple monitoring program was developed to check quality of virus collected at field level by farmers, especially in Parana and Rio Grande do Sul states. Virus use reached over 300,000 hectares in the season 1985/86, and is expected to reach 2.0 million hectares in next three years. A simple wettable-powder formulation of the virus has been developed at EMBRAPA-CNPSo and is already in use by farmers. An interinstitutional project aiming at developing methodology for large scale purification and formulation of the virus is underway and is expected to bring about industry exploitation of the enormous potencial for use of insect viruses in different brazilian agroecosystems.
