Notizen:
Several baculvirusus of nuclear polyhedrosis virus (NPV) have been produced and tested for microbial control of various Lepidoptera spp. To date, there are three registered preparations of NPV that are exempt from the requirement of tolerance by the Environmental Protection Agency (EPA) in the United States (US). The first and only commercially available viral preparation used in agriculture was developed by Sandoz, Inc. under the name of Elcar® for control of Heliothis spp. on cotton. The other two baculovirus preparations were developed and registered by the US Department of Agriculture (USDA) for control of Douglas-fir tussock moth and gypsy moth on forests. Several methods are being used for production of NPV viruses: (1) field collection of diseased larvae, (2) laboratory rearing of insects followed by infection with viral inoculum, (3) tissue culture. and (4) tissue culture and mass rearing larvae. Recent progress in mass production of insect virus points toward the adoption of tissue culture with the whole organism technology for production of a standardized viral product. The practical usefulness of various baculovirus preparations has been demonstrated for protection of forests from defoliation by various lepidopterous species. In agriculture, Elcar® has been successfully marketed and has been very well received for use in integrated pest management on cotton. Recent development also demonstrated that use of adjuvants further increase the efficacy of Elcar® against Heliothis spp. on cotton.
