Abstract
The bug, Lygus disponsi LINNAVUORI (Hemiptera : Miridae), could not grow to adult on a control diet (containing no carbohydrates), whereas it grew to adult on sucrose and starch diets. The rate of growth of the bugs on the starch diet was about equal to that on the sucrose diet. These facts indicate that carbohydrates are essential for their growth and that soluble starch has the same nutritive value as sucrose. It is probable that the bug fully utilized starch or polysaccharides in soluble form which may be contained abundantly in its host plant tissue, on which it is fond of feeding.
