Influence of weather factors on the trapped population of pink bollworm (Pectinophora gossypiella) under Multan Agro-ecosystem

Studies were carried out to evaluate the impact of weather factors on the population dynamics of pink bollworm for three consecutive years from 2009 to 2011 at Entomological Research Sub-station, Multan. Pheromone traps charged with Gossyplure [(Z, Z) and (Z, E) 7, 11 hexadecadienyl acetate] were installed and data for moth catches was recorded regularly at fortnightly basis. Simple correlation and regression coefficients were also computed to know the relationship between weather factors and moth catches. The results indicated that highest peaks of pink bollworm appeared during April having 1.1 and 1.13 moths/trap at 37.78 and 36.78 oC (maximum temperature), 22.00 and 20.12 oC (minimum temperature), 29.89 and 28.46 oC (average temperature) and 67% (RH) during 2009 and 2011 respectively whereas peak appeared in November and December during 2010. Out of weather factors, maximum temperature and rainfall showed positive response while minimum temperature, average temperature and relative humidity had a negative impact on the population fluctuation of pink bollworm. Regression coefficient showed 8.92% impact of weather factors in population fluctuation.
