Wuhan Institute of Virology,wuhan 430071
Jianghu Farm,Tianmen Hubei Province
It is the first time in china that the study of an insect virus gains commercial successes.This is owlng to the development of a new formulation──emulsifiable suspension, the im-provement of tectinology and facilities,which resulted in raising production efficiency and re-ducing cost. In this paper the establishment of Heliothisarmigera colony,the large-scale rear-ing, the NPV replication,processing of viral emulsifiable suspension, product inspection andfield effectiveness are reported. The effectiveness of Heliothis viral emulsifiable suspensionwas at least equivalent to that of the recommended chemical insecticides,and superior to thatof viral wettable powder. By using 1.2-2.4×10(12)PIB/ha,the pest population was reducedby an average of 9 1.7%,while is was reduccd by an average of 83.7%when using the wet-table powder at the same dosage.
