Summary. The capsid bug Lygus pabulinus has become a serious pest of currants, gooseberries, strawberries, potatoes and dahlias, and is also present on apples, pears, plums, cherries and peaches, and a large number of cultivated plants and weeds. A detailed account is given of the characteristics and measurements of the various stages which will serve the purpose of identification, and also of the genitalia. Diagnostic characters are given for the purposes of distinguishing it from the P. rugicollis which causes similar damage on currants and apples. There are two generations per annum. Eggs are laid in the autumn in woody plants such as currants, gooseberries, apples and roses and then migration to herbaceous hosts usually takes place where the summer eggs are laid, the second generation returning to the woody host to lay their eggs. In the first generation a secondary migration from strawberries to other herbaceous hosts takes place. Details are given of the damage done to the more important host plants and of the habits of the bug in its various stages. Control measures are given.
