摘要
根据调查,转Bt基因棉大面积种植后,棉铃虫、红铃虫发生减轻;棉叶螨发生加重,为害时间延长;甜菜夜蛾、斜纹夜蛾发生面积扩大,为害程度加重。据此初步提出了当地转Bt基因棉害虫防治中应注意的问题和管理对策。
According to the investigation, after transgenic Bt cotton was planted in a large area in Anqing city, the occurring amounts of Heliothis armigera and Pectinophora gossypiella reduced; the occurring amount of Tetranychus telarius increased and its damage (injury) time was extended; the occurring areas of Laphygma exigua and Spodoptera litura were expanded and the occurrence became more serious than before. Management strategies in addressing to the second pest resurgence in transgenic Bt cotton in Anqing were proposed.
