Economic Importance: This tingid causes damage to apple and pear in North Africa. It is also injurious to almonds, apricots, cherries, pears and plums in Italy and Spain. Feeding causes yellow spotting of leaves and in heavy infestations the foliage becomes coated with excreta. Severe attacks lead to defoliation, heavy losses of crop, and abnormal second growth. Monosteira unicostata has been intercepted occasionally at U. S. ports of entry. Distribution: Recorded in Albania, Czechoslovakia, Cyprus, France, Greece, Hungary, Italy (including Sicily), Portugal, Spain, Romania, Turkey, United Arab Republic (Syria), (Caucasus, Turkestan), Yugoslavia and North General Distribution of Monosteira unicostata Hosts: Almond, apricot, cherry, pear, apple, plum, peach, hawthorn, willow and poplar. Life History and Habits: Adults overwinter in cracks in tree trunks or in debris in the soil. Eggs are inserted into the leaf tissue along the veins on the underside of the leaves. The eggs hatch in 13-15 days. The nymphs undergo 5 molts and complete development in 25-30 days. There are as many as 3 or 4 generations annually with considerable overlapping late in the season so that all stages may be found at one time. Injury is reported to be more serious in late summer.
