Refuge crops are used in the cotton industry to dampen the expression of resistance in Helicoverpa moths, and are an integral part in the use of transgenic cotton varieties; as such it is important to confirm refuge assumptions. This experiment sampled 11 Conventional Cotton and 11 Pigeon Pea fields in January and February to compare the survivorship of Helicoverpa spp. It was found that both the attractiveness and productivity of Pigeon Pea and Conventional Cotton refuges were highly variable. Pigeon pea was more attractive for egg lays when flowering, but this attractiveness did not translate into more moths. Conventional Cotton Fields which were attractive in January, remained attractive throughout the sampling period, and were more reliable at producing moths than other fields; however there were many fields that were consistently unattractive. Overall there was no difference in Helicoverpa productivity between Conventional Cotton and Pigeon Pea refuges, contrary to the established notion that Pigeon Pea is twice as effective as unsprayed conventional cotton.
