| Abstract | ||
| The results of the current work showed that Lyctus brunneus Steph. beetles )Coleoptera : Bostrichidae) emerge from storage wood in closed places during different occurrence periods and consider as renewal source for infestation. Three occurrence periods were observed during storage period of about 24months. The 1st occurrence periods recoded 6 months of beetles emergence and appeared the highest percentage of emerged beetles (74.8%), followed by the 2nd occurrence which its duration 4 months and detected 17.48% emergence then 3rd occurrence which recorded the least percentage of emergence (7.72% emergence) through four successive months. The effect of temperature showed positive significant correlation with number of emerged beetles during 1st occurrence period, and the correlation was positive and highly significant during 3rd occurrence period. Whereas, the both of relative humidity and moisture content of wood gave highly negative significant correlation during the 1st and the 3rd occurrence periods, while the correlation was highly positive significant during the 2nd occurrence period for both relative humidity and wood of moister content. | ||
