Population dynamics of corn flea beetle and four- spotted leaf beetle on different maize cultivars at Peshawar

Abstract

The present study aimed to record population dynamics of corn flea beetle and four-spotted leaf beetle 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 corn flea beetle and four-spotted leaf beetle were found statistically non-significant on the seven tested maize cultivars. However, the overall mean density of corn flea beetle was recorded higher (2.26 beetle leaf -1 ) on Pahari cultivar and lower (2.10 beetle leaf -1 ) on Climax 30M62. Overall mean density of four-spotted leaf beetle was found maximum (1.23 beetle plant -1 ) each on Pahari and Azam and lower (0.99 beetles plant -1 ) on C-3055. 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.
