| Abstract | ||||
| Population fluctuation of Chlorophorus varius (Coleoptera: Cerambycidae), attacking mango trees was monitored at Ismailia governorate during the two successive years of 2010 and 2011. C. varius prevailed from early / late April to early November. Summer recorded the maximum flight (1.16 - 1.36 beetles), followed by spring (0.51 - 0.70 beetle), then autumn (0.15 – 0.18 beetle) /tree, and stopped during winter. The total numbers per year were 1.82 – 2.24 beetles / tree. It had two brood and the beetles' activity averaged 7 – 7.5 months. Effect of weather factors on the borers' activity was mostly positively significant with daily maximum, daily minimum and daily mean temperatures but negatively and insignificantly with daily mean relative humidity. Infestation was almost doubled during only one year, thus urgently need to apply integrated approaches for control. | ||||
