Dow AgroSciences, LLC has developed transgenic Bt-cotton expressing insecticidal crystal proteins of Bacillus thuringiensis (Bt). Genes for the expression of two proteins (Cry 1Ac and Cry 1F) have been inserted into cotton varieties and together, the trait is known as WideStrike*. Field and bioassay studies since 2001 have shown that WideStrike has excellent efficacy against a broad spectrum of lepidopterans attacking cotton, i.e., Heliothine and non-Heliothine. This presentation addresses efficacy against non-Heliothine insects. The studies reported here demonstrate that WideStrike provided very good or excellent control of the following non-Heliothine insects: Pectinophora gossypiella, Spodoptera frugiperda, Pseudoplusia includens, Estigmene acrea, and Ostrania nubilalis. In addition, WideStrike provided moderately good control of Agrotis ipsilon. [ABSTRACT FROM AUTHOR] |
