Muhammad Aslam, R. B. Chalfant and G. A. Herzog

Abstract

Anthonomus grandis grandis (Boheman), the boll weevil (BWVL), in a field experiment with 20 cotton strains planted in 3 levels [A (intense pesticide use), B (intermediate use of pesticides) and C (low pesticide use)] of pest management at the University of Georgia, Department of Entomology, Coastal Plain Experiment Station, Tifton, USA, showed low to equal oviposition and feeding preferences on GATIR 84-664 and PD-0786 (a frego bract strain), while on the other lines either intermediate or equal oviposition and feeding preferences were found compared with Stoneville 213 (a susceptible check). It showed equal oviposition and feeding preferences in the averages of level B and C and less in level A.
