Compatibility of Host-Plant Resistance and Biological Control of Heliothis spp. (Lep.: Noctuidae)

Thc available litcraturc concerning the compatibility of host-plant mittance and biological control, with particular reference to Heliofhisspp., is rcvicwed. There has been a large amount of successful research on host-plant resistance and biological control as individual components for the management of Heliofhis spp., and it has often been postulated that these cornponcnts are compatible, or even synergistic. However, there ue few reports of experimentation to test their compatibility. Research done at ICRISAT on the effects of host-plant resistance on parasitism in Heliothis armigera Hubner larvae on pigeonpea and chickpea is reviewed. It is suggested that the effect of host-plant resistance, on the hiocontrol elements must be tested in large plot field trials before thew components are used in integrated pest management projects
