Abstract
The study was conducted in Al-Jabel Al–Khder area located north east of Libya. This area in the last few decads experienced extensive apple tree cultivation. The aim of this study was to investigate the life cycle of the apple stem borer Z. Pyrina L. under the local climatic conditions, and identitfy its hosts, percent infesfation and its distribution. The data showed that the emergence of adults started from end of May to mid August. It has one generation per year with exception of few larvae (10-20%) that can stay in a quiescent stage until the next season. After egg-hatching the larvae stayed without feeding for 3 to 4 days, then started boring in the stem. It has six larval instars and lived about 9 months inside the tunels. The pupa lived from 4 to 6 weeks. The data revealed that the pest appeared to infest many plants in Al-gabal Al-Akhder and the most prefered hosts infested were apples, pears and nuts.
