lepidopteranAny of the more than 155,000 species constituting the order Lepidoptera (Greek: “scaly wing”): butterflies, moths, and skippers. The name refers to the dusting of minute scales that covers the wings and bodies of these insects. A slender proboscis is used for sucking. Nearly all lepidopterans are plant eaters, and species are found on every continent except Antarctica. Females may lay from a few to a thousand or more eggs at a time. All lepidopterans undergo complete metamorphosis. Many types move from one region to another, sometimes crossing thousands of miles of ocean, but the only species that truly migrates—the same individuals making a two-way flight—is the monarch butterfly. |

Gore is currently researching resistance management plans for lepidopteran pests on genetically engineered Bt cotton and the timing of cotton bollworm adults emerging from corn, soybean, grain sorghum and conventional cotton. In cotton, we've launched WideStrike[TM] Insect Protection--a two gene Bt trait--for season-long, broadspectrum lepidopteran control. Preparations of whole Bt have been used by farmers as an insecticidal spray for control of lepidopteran and coleopteran insects for at least 30 years (2). |
