Beneficial insects; Insect pests. 1078 - Life History and Habits: The biology under conditions In southern West Pakistan is as follows: Larvae overwinter In the ends of galleries In tree trunks or limbs. Pupation takes place in the early spring with adults emerging from the trees 10 to 15 days later. Mating occurs in 2-3 days in pairing chambers prepared by the males in the tree bark. After fertilization, the female makes an egg gallery. One male may fertilize two or more females. A female lays 50-70 eggs singly in pocket-like depressions along the 50-70 m

Beneficial insects; Insect pests. 1078 - Life History and Habits: The biology under conditions In southern West Pakistan is as follows: Larvae overwinter In the ends of galleries In tree trunks or limbs. Pupation takes place in the early spring with adults emerging from the trees 10 to 15 days later. Mating occurs in 2-3 days in pairing chambers prepared by the males in the tree bark. After fertilization, the female makes an egg gallery. One male may fertilize two or more females. A female lays 50-70 eggs singly in pocket-like depressions along the 50-70 mm. long egg gallery. Hatching takes place in 1 to 3 days. Larvae then excavate galleries at right angles to the egg gallery and parallel to each other. Larval galleries average 12-73 mm. in length, curve irregularly, and gradually Increase in size during the 4 weeks of larval development. Pupation occurs in cells made at the ends of the larval galleries. There are 4 generations a year with an average adult life span of days. Description: EGG - Diameter mm. Extremely small, shiny, spherical, and creamy, LSRVA (full-grown) - Length 6 mm. Oblong and cylindrical, legless, wrinkled, curved, and creamy white. Head small, brown, and partly concealed in the enlarged anterior portion of the body. PUPA - Length 4 mm. Soft, white or creamy white; head hidden beneath prothorax; legs and wing cases pressed close to the thorax, ADULT - Length 4-4,5 mm. Elongate oval, light yellow and brown, somewhat shiny with sparse white hairs. Elytra longer than thorax; punctations ranging from coarse at base to small at apex. Thorax darker than elytra coarsely punctate with sparse hairs. Antenna, tip of femur, tibia, tarsus, and apical elytral margin Adult (Dorsal and Ventral Views).
