The study was conducted in Field No. 42 of the Students’ Instructional Farm (SIF) under the Department of Agronomy, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, during the kharif season of 2019.The farm is situated at left side of the Grant truck road about one kilo meter away from the campus in gangetic plain of Utter Pradesh. The experiment was laid out in a Randomized Block Design (RBD) with six treatments and three replications. Each plot measured 4 × 4 meters, with a 1-meter spacing maintained between plots and between replications.Six insecticides were taken during trail, like are Chlorpyriphose 20EC, imidaclopride 17.8SC, Fipronil 5% SC, Dipel Bt, Quinalphose 25 EC and neem oil. Their common name, chemical name and sources from which they were obtained are given in table-1. The GLH population was observed during fourth week of July i.e. 24 day after transplanting and its reached peak level during first week of (20 t0 26) August at 34 standered week. The correlation (table 2) revealed that GLH population showed non significant positive correlation with morning RH (r 0.3172) and evening RH (r 0.3073), non significant negative correlation with maximum temperature (r-0.1302), and non significant positive correlation with minimum temperature (r 0.3888), evaporation (r-0.4361) further a non significant negative correlation was observed. The BSS (r-0.1708) show non significant negative correlation and positive non significant correlation with rainfall (0.1611) was observed with studied insect population.
