Population dynamics of macrotoma palmata f. (Col.: Cerambycidae)on casuarina trees in Alexandria, Egypt [electronic resource].

Includes references.

Population dynamics of Acacia stem borer, Macrotoma palmata F. (Col., Cerambycidae) was performed on casuarina trees in Alexandria, Egypt during 2009 and 2010. Results showed that older trees were highly infested especially those on the east side of the garden, as well as no preferred part of tree - trunk for occupation by this insect. Emergence of adult - beetles begins from the 1st half of June to late September in 2009 and 2010. The maximum mean number of emerged beetles ranged between 17.5- 19.5 beetles/ tree during the period from late July to early August under environmental conditions of 19.5 - 26.0 °C & 68.7 - 76.4% R. H. One peak of adult emergence was recorded per year in both seasons of study. The combined effect of day - maximum temp., day - minimum temp. and daily- mean relative humidity on the rate of beetles emergence were recorded. Repetition of infestation after two years later increased the infestation rate by 92.3%.
