“…As the larva bores inside the boll, the lint is cut and tied, resulting in a significant loss of cotton quality. The pest completes four generations on cotton crop and the fifth-generation rests on the left-over bolls on the cotton sticks and the bolls in the ginning factories (Hussain et al, 2021). Unlu and Bilgic (2004) reported that 1% increase in the infestation rate of PBW caused a 2.5-6.0% yield loss of cotton.…”

The present study was carried out in the farmers’ fields of Bhadradri Kothagudem, Telangana, India during Kharif (June–December) seasons of 2018, 2019 and 2020 to demonstrate the integrated pest management strategies for the management of pink bollworm and to know its rate of adoption among the farming community. The treatments consisted of technology demonstration and farmers’ practice. During three years of study, the population of pink bollworm has showed increasing trends. More than 10% of the rosette flowers were observed during the crop period starting from 36th SMW and continued up to 48th SMW. The green boll damage caused by PBW ranged between 2.1–19.2 in the demo plot, while the range was 2.2–20.6 in the control. Average population in pheromone traps was 4.48, 5.31 and 5.34 trap-1 during 2018, 2019 and 2020 respectively. Standard weeks 36–38 (3rd September–23rd September) 51–3 (17th December–21st January) were minimum or no activity periods due to low temperature, while standard weeks, 40–44 (1st October–4th November) were high activity periods during these study years. The population of pheromone traps correlated with temperature and rainfall had shown negative and non-significant correlation during 2018 and 2020, while positive and non-significant correlation during 2019. Cotton seed yield in the technology demonstrated plot was higher (1965, 2055 and 2095 kg ha-1) compared to farmers practice (1607, 1708 and 1725 kg ha-1) during 2018, 2019 and 2020 respectively. By adopting the IPM strategies against this pest, farmers’ can avoid the yield losses up to 22.3%. Nearly 65% of the respondents had medium level of adoption on management practices for the control of PBW.

“…As the larva bores inside the boll, the lint is cut and tied, resulting in a significant loss of cotton quality. Four generations completes its development on the cotton crop and the fifth generation rests on the leftover bolls on the cotton sticks and the bolls in the ginning factories (Hussain et al, 2021). Under dry conditions, the number of larvae in the bolls is directly related to the loss in the yield and quality of the produce.…”

Pink bollworm (Pectinophora gossypiella) is a destructive pest of agricultural crops especially cotton crop in Pakistan. It has ability to form rosette flowers, bolls and makes them unable to open. Thus it deteriorates cotton seed quality which has significant impact on yield reduction. Increasing trend of insecticides has resulted in insecticide resistance, environmental pollution and risks of human health. Integrated pest management has key role to reduce negative impacts. Besides of several other components, pheromone traps are best monitoring and mass capturing tool for bollworms in agricultural crops. The study was conducted to check relation of pink bollworm mass trapping in pheromone traps relating to environmental factors during three years study 2018 to 2020. Results indicated that pink bollworm has two peak activity periods during study years. Standard weeks (SW) 11 to 15 and 31-35 were highly active while SW 20 to 26 was inactive periods of pink bollworm. Adult moth population captures in pheromone traps was 3.14, 4.41 and 6.75/ trap during 2018, 2019 and 2020, respectively. Highest peaks were 11.12, 11.85, 15.94 /trap with maximum, minimum, average temperatures, relative humidity and rainfall of 29.43: 36.59: 35.28°C, 11.31: 21.36: 22.80°C, 20.37: 28.96: 29.04°C, 54.66: 61.23:58. 36% and 0.00, 0.00, 0.00 mm, during 2018, 2019 and 2020, respectively. Temperature 20- 30°C had significant impacts to speed activities of pink bollworm. Minimum (r= -0.165, -0.144, -0.582) and maximum (r= -0.078, -0.045, -0.192) temperatures had negative and non- significant correlation with population in pheromone traps while average temperature had positive and significant correlation (r= 0.112, 0.290, 0.486) during study years. Average temperature had maximum impact of 20.9 (0.01), 20.7 (0.03) and 9.3 (0.07) % on population variability during 2018, 2019 and 2020, respectively. Population trends of pink bollworm had shown increasing trends during the subsequent years. Pheromone traps proved best monitoring tool of pink bollworm to integrate into integrated pest management strategy.
