Abstract
The present study was carried out in Zagazig district, Sharkia Governorate, Egypt in cotton fields (Gossypium barbadens) Giza 86 during 2014 and 2015 seasons to study investigate the population fluctuation of pink bollworm, (PBW) Pectinophora gossypiella (Saund.), spiny bollworm, (SBW) Earias insulana (Boisd.), and cotton leafworm, (CLW) Spodoptera littoralis (Boisd.). Results indicated that the population of the (PBW) male mothshad five peaks in the two investigated seasons. The highest peak of male moths was recorded during the 4th week of September through the aforementioned seasons with 180 and 176 male moths/trap/week in both seasons, respectively. In case of (SBW) male moths had four and three peaks in the two seasons. The highest peak of moths was recorded during the 2nd week of September during two seasons. The population occurred with 48 and 51 male moths/trap/week in both seasons, respectively. Cotton leaf worm male moths had four peaks in the two seasons. The highest peak of moths was recorded at the 1st and 2nd week of May during two seasons, respectively, with 420 and 630 male moths/trap/week in both seasons, respectively. Statistical analysis showed that the relationship insignificant during the two seasons of study, between weekly mean numbers of PBW and SBW male moths caught in pheromone traps and maximum, minimum temperature and mean RH (%). In case of CLW, the relationship between weekly mean numbers and maximum temperature and mean RH (%) was insignificant in the two seasons of study, but it was significant between male moths and minimum temperature in the season of 2014.We conclude from the foregoing that it can use three types of traps sexual attraction for each of the pink, spiny bollworms and cotton leafworm in forcast census male moths for use in Integrated Pest Management program.
