| 摘要 |
The present invention relates to compositions and methods of their use for the management or biocontrol on insect pests. The compositions comprise an entomopathogen and a chitin synthetase inhibitor alone or in combination with a UV protectant. Alternatively, compositions are disclosed comprising an entomopathogen and a fluorescent brightener of the stilbene type which may have chitin synthetase inhibitory properties. Specifically, entomopathogens such as Nuclear polyhedrosis viruses (NPV), Cytoplasmic polyhedrosis viruses (CPV), Entomopox viruses (EPV) and Granulosis viruses (GV) and iridescent virus (IV) are protected from UV radiation and their biological activity enhanced using fluorescent brighteners analogs, particularly, 4, 4'-diamino-2, 2'-stilbene disulfonic acid.
