棉花收成高取决于许多因素,其中棉花害虫及时和适当地防治是一个重要的因子。有三类棉铃虫即:实蛾类、棉铃虫和棉红铃虫为害棉花作物,并造成籽棉明显损失。据报道,有机氯类、有机磷类和氨基甲酸酯类杀虫剂,防治棉铃虫是相当有效的,后有报道,许多拟除虫菊酯防治棉铃虫高效。除了化学农药外,苏云金杆菌(B.t.)在棉铃虫综合治理中也发挥着重要的作用。本研究旨在评价防治棉铃虫新药剂(包括苏云金芽孢杆菌肯尼亚变种)的相对药效。
The high cotton yield depends on many factors, including the timely and proper control of cotton pests is an important factor. There are three types of cotton bollworm: real moth, cotton bollworm and cotton bollworm damage cotton crops, and caused significant loss of seed cotton. It is reported that organochlorides, organophosphorus and carbamate insecticides are very effective in controlling cotton bollworm. It has been reported since then that many pyrethroids are effective in controlling cotton bollworm. In addition to chemical pesticides, Bacillus thuringiensis (B.t.) also plays an important role in the integrated management of cotton bollworms. The aim of this study was to evaluate the relative efficacy of new agents against Helicoverpa armigera (including the Bacillus thuringiensis variant of Kenya).
