. Cooperative economic insect report. Beneficial insects; Insect pests. 64 Life History and Habits: Life history of H. brevis in the Crimea of USSR is as follows: Larvae overwinter in cocoons in The soil, some just below the surface and some at depths down to 8 inches. Pupation occurs in mid-March. The adults appear when pear buds are separating, being present for 8 to 10 days. Reproduc- tion is parthenogenetic. The females contain fully developed eggs upon emergence. Each female deposits from 37 to 40 eggs, singly, on the lower halves of the flower buds. There are usually 4 eggs per bud. Larv

Beneficial insects; Insect pests. 64 Life History and Habits: Life history of H. brevis in the Crimea of USSR is as follows: Larvae overwinter in cocoons in The soil, some just below the surface and some at depths down to 8 inches. Pupation occurs in mid-March. The adults appear when pear buds are separating, being present for 8 to 10 days. Reproduc- tion is parthenogenetic. The females contain fully developed eggs upon emergence. Each female deposits from 37 to 40 eggs, singly, on the lower halves of the flower buds. There are usually 4 eggs per bud. Larvae hatch in 6 to 8 days and feed within developing fruits, destroying seeds and migrating from one fruit to another until full-fed. Feeding lasts from 21 to 23 days during which each larva will damage up to 4 fruitlets and pass through five larval instars. In mid-May, the mature larvae drop to the ground, usually in the infested fruitlets, and then enter the soil to overwinter. Some larvae will not pupate the , but will remain dormant until the succeeding year. Description: Adult is 4-5 mm. in length. Mesonotum brown, spotted black. Stigma light yellow, base brownish. Head and antennae brownish-yellow without black coloring apart from the eyes. Thorax reddish-yellow, mesonotum somewhat darker with dark streaks on the individual sclerites and on the base of the scutum. Metanotum black. Mesonotum densely punctured. Legs yellow, wings hyaline with yellow veins. Dorsal surface of abdomen black, ventral surface yellow. Egg is white and translucent, measuring by mm. Fifth-instar larva is about 7 to 9 mm. long; head with brown spot on irons, otherwise tan; no conspicuous caudal tergites. The body and legs are pale green and claws brown. There is a slight darkening of the dorsal surface of the anal segment, somewhat less on ninth seg- ment and slightly noticeable on eighth segment. The cocoons are dark brown and rough-coated due to sand particles adhering to su
