“…The population of natural enemies was increased with increase in hosts. 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).…”

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.

The research work was carried out in different agro-eco-zones of Sindh, Pakistan at the experimental field area of Cotton Agriculture Research Station at Tandojam, Sakrand, Kotdiji and Sarhad, 2019. The peak population of the Dusky cotton bug (DCB) was recorded at Tandojam. The high population of natural enemies like Chrysoperla, Orius, and Mirid bug was observed from July to September. The peak pest of pest observed averagely at Tandojam and Sakrand (49 to 23%). The abiotic factors like temperature and humidity averagely at Tandojam and Sakrand (32 to 50%) followed by Kotdiji and Sarhad (41 to 18%) recorded ideal for Chrysoperla, Orius, and Mirid bug. The abiotic factors were recorded as favorable for natural population multiplication like temperature and respectively. The weather factors noted optimum for spider population at Tandojam. It was concluded that the peak population of the pest was observed in different agro-eco-zones from September and October.
