| Abstract | ||||
| . The effect of certain. weather factors (daily maximum and minimum temperature, relative humidity and wind velocity) on the seasonal abundance of Earls insulana (Boisd.) adult males' during 2002, 2003, and 2004 cotton growing seasons was studied. The obtained data showed that E. insuJana males exhibited 3-4 peaks of flight activity 'in .response to sex pheromone traps. The highest occurence was observed July - August. . E. insulana males showed positive response to the increase of temperature and relative humidity. The amount of variability attributed to combined effect of weather factors on E. insulana male populations was different from year to year. Maximum temperature and relative humidity were the most effective factors on E. insulana populations ... | ||||
