Abstract
In biological control program Predators are exploited to manage pest population. The objective of present study was to find relationships between predator's Coccinellid septempunctata, Lynx spider and preys Helicoverpa armigera, Pectinophora gossypiella, Earias vitella populations found on cultivated cotton crops (government approved varieties) in Southern Punjab, Pakistan. Data was collected after ten days of interval during crop season from 2014 to 2016 randomly. Significant Correlations coefficients were observed which can be used for effective pest control program to predict predator prey ratio.
