In 1959 the flat red mite was widespread on apples and pears in Turkey where it caused much concern. Considerable damage to apple trees occurred in Cyprus where extremely high populations were noted at 2,000-4,000 feet elevation. An average of 100 mites per leaf has been observed on a heavily infested tree. In some areas C. pulcher is found only on neglected apple trees. Damage to buds and flowers of~quince has been reported from Libya. Distribution: Afghanistan, Austria, Bulgaria, Cyprus, Egypt, Germany, Iran, Israel, Lebanon, Libya, Netherlands, Syria, Switzerland, Turkey, and USSR (known only in parts of Crimea, Transcaucasia and Soviet Central Asia where it is widely distributed). Hosts: Apple, pear, quince, loquat, poplar, willow, damson, walnut, and dogwood. \ \ \ \ \ \ \ \ \ I I I I I, I L L i t L t 4_/ /,—L. General Distribution of Cenopalpus pulcher (Canestrini and Fanzago) Life History and Habits: Under conditions in England females overwinter in cracks in the bark but are active early in the spring Although they wander around on the leaves in April, they do not completely move there until May. Egg laying begins late in April on the bark. Later, eggs are deposited on the midrib or leaf veins, usually underneath the leaf hairs. Oviposition continues until the middle of July when the overwintered females die. Hatching occurs at the end of June and nymphs mature in late July For a time males outnumber females but after mating in August and September, the males gradually die off. Only one gener- ation a year is recorded in England but two are known in Bulgaria. Acarina: Tenuipalpidae No. 179 of Series.
