Every year, entomologists from the National Cotton States Arthropod Pest Management Working Group are polled on insecticide efficacy. This group consists of university Extension entomologists across the Cotton Belt. The ratings are based on experience of those in the group and, from my perspective, are relatively accurate. Each entomologist is asked to rate the insecticide from 0 to 10, with 0 = not effective and 10 = completely effective.
Responses are also broken out by region (MS= Midsouth, SE= Southeast, W= West). Insect abbreviations are as follows:
BW= bollworm
TBW= tobacco budworm
BAW= beet armyworm
FAW= fall armyworm
SL= soybean looper
CL= cabbage looper
ECB= European corn borer
PBW= pink bollworm
SAW= southern armyworm
SMC= saltmarsh caterpillar
CW= cutworm
G/SG stink bug= green/southern green stink bug
