Bayer distributes earworm traps in Brazil
Bayer CropScience has distributed some 5,200 traps for the capture and monitoring of earworm (Helicoverpa armigera) infestation levels in Brazil, national media report. The traps are designed to monitor egg laying by earworm moths, allowing estimates of new earworm populations in cotton, maize and soybeans. They employ a pheromone used to attract earworms and other pests, such as tobacco budworms (Heliothis virescens), and soybean loopers (Pseudoplusia includens). The major goal of the company's "Bayer Against Earworms" project is to create a data network interactively aiding growers to make decisions on the efficient use of pesticides and promoting appropriate practices. The authorities are concerned at heavy use of insecticides to control earworms.
