Beneficial insects; Insect pests. 523 INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES APPLE CAPSID (Plesiocorls rugicollis (Fallen)) Economic Importance: This mirid is a pest of several fruit and ornamental trees in the paiearctic regions of Europe and Asia. It has been considered the most serious pest of apples in Britain. Entire crops of apples have been made ,, unsalable due to deformed fruit. On apple, infestations produce deformed, ragged and undersized leaves. The shoots are also killed. This encourages formation of excessive side shoots, resulting in a badly shaped, stunted tree. The most obvious damage is on the fruit. The skin is rough and russeted with scattered pits and pimples. Severely damaged fruits often have deep cracks. In addition to apples, black currants are often severely damaged, the foliage being almost totally destroyed on occasions. Distribution: Apple capsid has been generally recorded throughout northern and central Europe and through the paiearctic region of Siberia. It has also been recorded in Algeria and Italy in the Mediterranean area and in parts of Alaska on the North American Damage to Apple.
