苏云金芽孢杆菌和白僵菌混配对酒曲害虫大谷盗的毒杀效果研究

利用苏云金芽孢杆菌与白僵菌混配杀灭酒曲害虫大谷盗。研究结果表明：在温度30℃、相对湿度为60%～69%条件下,苏云金芽孢杆菌与白僵菌液体制剂按1∶1比例混配后,使用量为4.5mL时,在杀虫第24d可使大谷盗的死亡率达96.0%,校正死亡率达94.7%。与试验前相比,酒曲的糖化力、液化力、发酵力分别下降了19.4%、19.8%、7.4%;而空白对照组则明显下降,分别下降37.5%、45.2%、29.7%。

Study on Insecticidal Effectivity of Bacillus Thuringiensis Pesticide with Beauveria Bassiana to Starter Insect Tenebroides Mauritanicus Panzer

The insecticidal effectivity of mixture of Bacillus thuringiensis pesticide with Beauveria bassiana to starter insect Tenebroides mauritanicus Panzer was studied.The research indicates that when the temperature is 30℃ ,the Relative Humidity is 60% -69%, the mixture which the ratio of Bacillus thuringiensis and Beauveria bassiana is 1：1 ,the treated volume is 4.5ml, it can kill the insect Tenebroides mauritanicus Panzer efficiency. The mortality and the corrected mortality can reach up 96.0% and 94.7% in the 24th day.The glucoamylase activity, the liquefying power, and the fermentive activity compared with the previous tests ,decrease by 19.4%,19.8%,7.4%. Comparing with the previous tests, the acoerast groups decrease markedly by 37.5%, 45.2%,29.7%, respectively. While the microorganism is changed little.
