The velvetbean caterpillar, Anticarsia gemmatalis, is the key defoliating insect of soybean from northern Argentina to Southeastern USA. In Brazil it is abundant in all soybean growing regions, and demands an average of two insecticide applications per season. In the early 1980's a program for use of a nuclear polyhedrosis virus of A. gemmatalis (AgMNPV) was launched by Embrapa Soja and the official extension service of the state of Paraná (Emater-Pr), in the context of a soybean integrated pest management (IPM) program started in the mid 1970's. Currently the biological product based on the AgMNPV is produced by four private companies, through contracts with Embrapa Soja, and used in approximately 2.0 million hectares of soybean in Brazil (ca. 12% of the soybean cultivated area in the country), being the largest program worldwide regarding the use of a microbial insecticide in a single crop. Production of the AgMNPV has been effected mainly in the field, by applying the virus in farmer's fields and collecting dead larvae for further processing as a biological insecticide, with quality control of the final product batches being performed at Embrapa Soja. However, this method of virus production is dependent of biotic and abiotic factors, which influence abundance of the host insect and thus the yield of AgMNPV each season. In the last three seasons the demand for the biological insecticide was 20-30% over of its availability in the market. Previous attempts by private companies to produce the virus under laboratory conditions were not successful due to the high costs involved, mainly insect diet ingredients, insect-rearing recipients and labor, making the final AgMNPV product not cost competitive with chemical insecticides. In this paper, we report a new procedure for commercial production and processing of the AgMNPV under laboratory conditions that results in a final product with lower cost than that of chemical insecticides, which will be a breakthrough to attend the increasing demand for the biological insecticide. One of the companies (Coodetec) is currently implementing successfully the new procedures at commercial level. Furthermore, data on fluorescent brighteners mixed with the AgMNPV indicate that these products may improve the virus formulation by potentializing viral activity against susceptible A. gemmatalis larvae and breaking resistance in insects that were selected in the laboratory to high levels of resistance to the AgMNPV. Other important recent developments to improve the program will be discussed.
