For abiotic factors, the spiders showed strong positive correlation with humidity and temperature. Surrounding habitats showed non-significant effect on population densities of insect pests and predators. Spiders’ population was encouraging at both vegetative and flowering stage and also the same trend of jassid and whitefly were observed at both stages of the crop. Fluctuated populations of predatory arthropods, spiders and green lacewings were also recorded during whole cropping season however, the densities of pests and predators varied with crop phenology. Whitefly was the most dominant sucking pest found on the vegetative stage of cotton, followed by jassid and thrips.

For sampling and survey of insects, the visual counting was found to be the most efficient method for recording the abundance of insects, trailed by net sweeping and tapping. The effects of surrounding field crops on pests’ density and predatory efficiency of predators were also recorded. green lacewings and spiders in cotton field plots.

Aim of the current study was to record seasonal dynamics of major sucking insect pests including whitefly, jassid, thrips and their natural arthropod predators i.e.

Sucking pests are major threat to cotton field crop which cause unbearable losses to the crop yield.
