生物配方农药防治竹瘿广肩小蜂药效研究OACSTPCD
Study on the Efficacy of Biologically Formulated Pesticide in Con-trolling Aiolomorphus Rhopaloides Walker
为找出防治竹瘿广肩小蜂的最佳有效药剂.本研究将球孢白僵菌(Beauveria bassiana)、苏云金杆菌(Bacillus thuringiensis)、吡虫啉混配成不同的复配农药,在桂林市兴安县华江瑶族乡锐炜村毛竹林进行竹瘿广肩小蜂(Aiolomorphus rhopaloides)的田间药效比较试验.结果表明:150亿孢子/g球孢白僵菌和32 000 IU/mg苏云金杆菌(质量比例1∶3,浓度3.3 g/L)配方是防治竹瘿广肩小蜂的最佳配方药剂;施药8 d后,死亡率达到99.3％.4月下旬至5月上旬是使用该复配农药的最佳时期.白僵菌与苏云金杆菌混合的生物配方农药防治竹瘿广肩小蜂效果高于化学防治,且害虫不易产生抗药性,并满足竹笋绿色生产的需要.本研究的生物配方农药是一种环保、高效的绿色农药.
In order to find out the best and effective fungicide to prevent and cure the Aiolomorphus Rhopaloides.In this study,Beauveria bassiana,Bacillus thuringiensis and imidacloprid were mixed into different compound pesticides.Afterward,their field efficacies in Aiolom-orphus rhopaloides was compared in a Phyllostachyspubescens forest in Ruiwei Village,Huajiang Yao Ethnic Township,Xing'an County,Guilin City.The results showed that B.bassiana and B.thuringiensis(mass ratio 1∶3,concentration 3.3g/L)composed the optimal formul-ation for controlling A.rhopaloides.Eight days after the application,the pest mortality reached 99.3％.Moreover,it was also found that late April to early May are the optimal control interval for this biologically formulated pesticide.The biocontrol effect of this biologically for-mulated B.bassiana-B.thuringiensis pesticide formula on A.rhopaloides was higher than chemical control,and the pests don't develop pes-ticide resistance,hence meeting the needs of environmentally-friendly bamboo shoot production.All in all,don't the proposed biologically formulated pesticide in this study is an environmentally-friendly and efficacious green pesticide.
