| Abstract | ||
| The shot-hole bark-beetle, scolytus amygdali Guer. is a major polyphagous pest in Egypt attacking fruit, wood and ornamental trees. Peach orchards however are liable to attack by this pest. Hosts and rates of infestation in each governorate were recorded. The seasonal fluctuation in the population was monitored on peach trees in Alexandria and Giza governorates throughout the three successive years 1987, 1988 and 1989. Beetle emergence started during February - March and continued until December. Beetle emergence is affected with the temperature and relative humidity at the time of emergence as well as during 0.5 - 1.5 months before emergence. Periods of occurrence and peaks of annual broods were approximated. | ||
