Study on the population densities of grass hopper and armyworm on different maize cultivars at Peshawar

Abstract

The present study aimed to record Population densities of Grass hopper and Armyworm on different maize cultivars at Peshawar was conducted at Agronomy Research Farm (ARF), The University of Agriculture, Peshawar (UAP), Pakistan during 2015. Seven maize cultivars, namely Azam, Jalal, Babar, Pahari, Iqbal, Climax 3055 and Climax 30M62 were tested. The overall mean density of grass hopper and armyworm were found statistically non-significant on the seven tested maize cultivars. However, highest overall mean density of grasshoppers of 0.48 grass hoppers plant-1 was found on Azam while lower of 0.42 grass hoppers plant-1 on each of C-3055 and C-30M62. Overall mean density of worms was recorded higher of 0.77 worms plant-1 on Pahari while lower of 0.66 worms plant-1 on C-30M62. On the basis of lower incidence of insect pests, all of the seven tested maize cultivars are recommended for cultivation during spring season at Peshawar.
