| Abstract | ||||
| Biology of the powder post beetles, Lyctus linearis Goeze (Lyctidea: Coleoptera) was investigated under laboratory conditions. The female of beetles lay its eggs in the pores on the wood surface. The insect undergoes had four annual generations. The incubation period of 1st, 2nd, 3rd and 4th generations was 7.2, 6.8, 7.9 and 10.7 days, respectively. Rate of hatchability ranged between 66 % and 100 %. The duration of the larval stage ranged between 28 and 103 days during four annual generations. The pre- pupa, pupa, adult hardness and adult longevity durations were averaged 1-5, 6-15, 1-5 and 11-29 days, respectively | ||||
