The Role of Host Plant Resistance in Lygus Management

William R. Meredith, Jr.


This review covers reasons why more attention should be given to Lygus spp. HPR. Two changes have occurred in growing cotton that places a higher priority on developing cotton varieties with resistance to Lygus spp. than in previous years. The use of transgenic Bt has at present, greatly reduced the need for the use of insecticides to control the budworm-bollworm complex. Insecticides applied for these insects also reduced Lygus populations. Second, insecticides that once were effective in controlling Lygus are no longer effective. A third reason for using (HPR) is that use of another control method increases the effectiveness and longevity of use of other insect control measures.
