Abstract

The biological characters of Scolytus nitidus were investigated both in the field and in the laboratory as well. This common shot-hole borer overwinters in larval stage on apple trees in Kashmir. After emergence the adults fly to suitable trees and undergo maturation feeding for 4-6 days. The copulation takes place at the entrance hole. The maternal gallery is one armed longitudinal, in average 4.6 cm long. The female lays 52 eggs on an average. The eggs hatch in 5 to 7 days. The larvae have 5 instars and complete their development in 38 to 50 days constructing larval galleries 5-8 cm in length. The larvae pupate for 6-18 days and finally the adults emerge to attack new suitable trees. The adults live for 45-60 days and the total life-span of this species ranges from 97 to 124 days. The seasonal distribution of various life stages and the number of generations were also recorded.
