Interpretive Summary: Lygus bugs cause a condition on lentil known as Chalky Spot' which is a physical abnomality of the seeds. That abnormality is a general discoloration of the seeds to varying degrees and a chalky condition of the cotyledons of the seeds. It is a serious quality problem and reduces the grades on which growers are paid for their crops. In this report we describe the cause of chalky spot and the resultant degradation of crop quality. Control methods including insecticides and cultural practices are reviewed and discussed.
Technical Abstract: A multidisciplinary, collaborative research effort generated complementary data lending substantial support for the hypothesis that: "Feeding of Lygus spp. on immature pods can lead to reductions in quality and losses in the quantity of seeds harvested from crops of lentil (Lens culinaris)". Knowledge of research findings on food legumes other than lentil was an important contributory factor in formulating the hypothesis tested. Use wa made of the experience and expertise of : farmers, industry administrators, extension specialists, seed graders, food scientists, plant breeders, entomologists, pathologists, botanists, chemists, and physiologists. The element of "novelty" and perceptions of prospects for "success: were important factors in the collaborative research effort. Clearly, specialists cooperating in research directed towards carefully formulated and agreed objectives can make rapid and important advances towards the solving of practical problems in food legume crop production.
