The red palm weevil Rhynchophorus ferrugineus is the most serious and destructive insect pest for date palm trees in Egypt . this work was undertaken in Ismailia region at district contained highly infested date palm trees with the insect . the aim of this work was to study the of using the aggregation pheromone as monitor to the insect infestation and the role of certain intervening factors
The results indicated the following :
1-Five to six peaks were recorded for in the insect during the period from March to November
2-The numbers of captured females were about twice that of males
3- Significant positive correlation was found between temperature sun shine, and wind velocity in one and number s of captured adults in other side .Relative humidity showed negative correlation.
4-four generation per year were recorded for the adults
5- Significant positive correlation was found between number of damaged trees and the captured adults.
6-The combined effect of both sugarcane stem or sugarcane honey were more attractive capturing than pheromone alone .
7- pheromone release was increased by increasing and wind velocity while decreased humidity.
8- The maximum potenional of cogenesis in ovaries of captured females was recorded during August .
