英文摘要	Helicoverpa armigera single nucleocapsid nucleopolyhedrovirus (hasnpv) has been developed as a commercial biopesticide to control the cotton bollworm, h. armigera, in china. the major limitation to a broader application of this virus has been the relative long time to incapacitate the target insect. two hasnpv recombinants with improved insecticidal properties were released in bollworm-infested cotton. one recombinant (hacxw1) lacked the ecdysteroid udp-glucosyltransferase (egt) gene and in another recombinant (hacxw2), an insect-selective scorpion toxin (aait) gene replaced the egt gene. in a cotton field situation h. armigera larvae treated with either hacxw1 or hacxw2 were killed faster than larvae in hasnpv-wt treated plots. second instar h. armigera larvae, which were collected from hacxw1 and hacxw2 treated plots and further reared on artificial diet, showed reduced st50 values of 15.3 and 26.3%, respectively, as compared to larvae collected from hasnpv-wt treated plots. the reduction in consumed leaf area of field collected larvae infected with hacxw1 and hacxw2 was approximated 50 and 63%, respectively, as compared to hasnpv-wt infected larvae at 108 h after treatment. these results suggest that in a cotton field situation the recombinants will be more effective control agents of the cotton bollworm than wild-type hasnpv.
