Cotton is most important fiber crop of Pakistan. Cotton contributes 1.6% in GDP of Pakistan. The sucking and chewing insect pests attack on the cotton and cause yield reduction. Among sucking pests, Thrips tabaci is the major one. The study was conducted to observe the ecological impacts of PB ropes on population dynamics of T. tabaci as well as beneficial fauna on cotton. The study was conducted at MNS University of Agriculture Multan at experimental farm Multan on an area of 27 acres. The experimental plot was divided into 3 blocks and each block consisted of 3 acres. Cotton variety NIAB-878 was cultivated as test crop and data was recorded on weekly bases from 20 random selected plants in each sub-plot for sucking insect pests and 10 plants for beneficial insects. The results revealed that population of T. tabaci remained significantly lower in double application of PB-ropes in a season treated plots as compared to treatment i.e., one application of PB-ropes + insecticides, while higher population was recorded in untreated block, managed through use of pesticides. The study resulted that all recorded green lacewing and Geocoris were showed negative correlation with T. tabaci and kept its population at minimum level as compared with control.

“…Our findings are similar with findings of early researchers (Solangi et al, 2005). PB-ropes were installed against Pectinophora gossypiella to check mating disruption on population its densities (Lykouressis et al, 2004). Population of pest was less in treated plot as compared to control.…”

“…Sufficient gossyplure for reducing moth catches in traps was present in pheromone dispensers even after 90 days. Our findings are also similar to the study of Lykouressis et al (2004) who observed the mating disruption effects on population dynamics and percentage of damage caused by pink bollworm. The results revealed that moth catches were highly reduced in the treated fields and mid-season installation of dispensers was successful.…”

Pink bollworm, Pectinophora gossypiella (Saunders), (Lepidoptera: Gelechidae) is considered as a notorious and destructive pest in the world and can reduce cotton yield up to 30% if not managed properly. Insect pest management through mating disruption technique offers practically an ideal approach to combat the pests. In the present study, the efficacy of mating disruption dispensers (PB rope L) for the management of pink bollworm was evaluated and the percent infestation in bolls and leftover bolls was determined in the cotton growing areas of Punjab, Pakistan during 2017. The PB ropes @100 per acre were used for each treated field of approximately 50 acres with a block of 10 acres as a control plot in the same union council of the treated plot. Calculation was made by comparing infestation and cotton yield in treated field with that of control field. The PB rope significantly reduced both the number of males in the sex pheromone traps and cotton bolls damage. Results revealed that PB rope during the first pin square period (45 days after sowing) effectively minimized the damage even in leftover bolls. The yield of treated field was enhanced compared with control field by 31% in 2017. Infestation in leftover bolls was estimated by comparing cotton bolls collected from control field with bolls from the treated field. The results reflected 1.56% damage in control field and 0.30% damage in treated field with a difference of 1.26 (80% reduction in damage in treated plots). Result indicated that PB rope disrupted the pest mating effectively during July to October.

“…Only the Ulala, Ulala+buprofezin and Polo were applied during the whole cropping season of cotton for sucking pests. Our results agreed with Lykouressis et al (2004) who applied PB rope dispensers in cotton field and observed that population of pink bollworm reduced effectively and populations of other cotton pests, such as whiteflies and aphids, were also reduced in those experiment areas. Similar observations were recorded by Lykouressis et al (2005) who conducted experiment and the one field was applied with PB ropes and in the other insecticide was applied.…”

Excessive amount of insecticides destroys natural enemies of cotton pests and consequently the population of whitefly flares up. The present research focused on the use of PB ropes to reduce application of insecticides and to investigate the ecological impact on Bemisia tabaci and beneficial fauna in cotton fields. Two cotton varieties (BS-15 and NIAB-878) were sown in research area of MNS University of Agriculture, Multan during 2018 on 30 acres. PB ropes dispensers (PB-ropes L®) were installed at 120/acre at pin head square stage of cotton. It was observed that application of PB ropes reduced need for insecticide applications, thus helped conservation of beneficial fauna in cotton fields throughout the season, which kept whitefly populations below EIL. Population of whitefly nymph was reduced after application (0.9/leaf-seasonal average) in PB ropes treated fields as compared to untreated check (8.1/leaf-seasonal average). Furthermore, higher population of green lacewing (4.00/plant) was observed in PB ropes treated field. It was concluded that populations of whiteflies were kept below EIL due to conservation of green lacewing. This positive effect of PB ropes is presumably due to increasing the number of cotton insect pest biological agents. This indirect effect of mating disruption (PB ropes) is of great value within the framework of IPM in cotton.
