Abstract
Field trials were carried oul at Meet EI.Deeb, Kalr E)-Sheikh Governorate during couorr growing seasons 2001 and ZQ()2 to predIct the infeslation level by Ihe spiny bollworms carias ;nS'Jlana 0(1 two cotton varieties usin!] sex pheromone traps, Protective treatments using aircraft according to the national programm on bollworm were conducted coincided. The possible correlation between the recorded caught males and both of cotton variety and some weather factors were statistically analyzed, fO\Jr generations were recorded on Giza 89 and Giza 86 during 2001 season. On the other hand, the same number of generations was recorded wilh Giza 86 in the second season whUe five generations were recorded with Giza 89 variety.
Slatistical analysis of the mean number of male moths and Rercentage of boll infestation by larvae showed highly signifICant correlation in 2001 season with the two tested varieues, Where it was positively insignificant with Giza 89 a d negatively insignificant with Giza 86 during 2002.
The relationship between the maXimum, ml"imum temperature and relative humidity on the fluctUation of the spiny bollworm male moths was found to be negative with Giza 89 while it was positive with Giza 86.
