Field study of pheromone trap catches of codling moth Cydia pomonella (L) (Lepidoptera; Tortricidae) in relation to weather parameters at Madyan Swat Pakistan

Abstract

Study was carried out to investigate population dynamics and impact of abiotic factors (Temperature, relative humidity and rainfall) on trap catches of apple codling moth (Cydia pomonella) at Madyan Swat in an unmanaged orchard during the year 2012-13. Results revealed that the first peak population (11.0±1.03 moths/trap) of C. pomonella was observed in 27th standard meteorological week (SMW), whilst the second peak population 10.25±0.9 moths/trap was in 33rd SMW. During the year 2013, the first and second peak population at Madyan was 10.25±0.81 &9.00±0.70 moths/trap in 29th and 35th SMW respectively. Correlation matrix revealed that C. pomonella showed statistically highly significant (p
