. 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 ...
