摘要
明确乙基多杀菌素悬浮剂、短稳杆菌悬浮剂和甲维盐水分散粒剂3种新型杀虫剂对樱桃果蝇的最佳使用剂量和防治效果,为生产应用提高科学依据。采用常规喷雾法进行试验。结果表明,24、30和40 mg/L的60 g/L乙基多杀菌素悬浮剂,5.00、6.25和8.33 mg/L的5%甲维盐水分散粒剂,以及1.00×107、1.11×107和1.25×107孢子/mL的100亿孢子/mL短稳杆菌悬浮剂对果蝇的防治效果分别为89.02%95.53%、86.99%91.87%和87.40%92.28%。综合试验结果和生态安全等因素,3种杀虫剂是防治樱桃果蝇的理想药剂。在樱桃果实膨大期及果实转色期,建议交替使用3040 mg/L的60 g/L乙基多杀菌素悬浮剂、6.258.33 mg/L的5%甲氨基阿维菌素苯甲酸、1.11×1071.25×107孢子/mL的100亿孢子/mL的短稳杆菌悬浮剂进行防治,以延缓其抗药性的产生。
This paper aims to study the optimum dosage and control effect of 3 insecticides, spinetoram suspension concentrate, Empedobacter brevis suspension concentrate and emamectin benzoate water dispersible granule against cherry drosophila, and to provide a scientific basis for the production and application. The field trial was conducted by routine spraying. 60 g/L of spinetoram suspension concentrate(24, 30 and 40 mg/L), 5%of emamectin benzoate water dispersible granule(5.00, 6.25 and 8.33 mg/L) and 10 billion spores/mL of Empedobacter brevis suspension concentrate(1.00×107, 1.11×10~7 and 1.25×10~7 spores/mL) could effectively control cherry drosophila, the field efficacy was 89.02%-95.53%, 86.99%-91.87% and 87.40%-92.28%,respectively. Based on the experiment results and the ecological safety, the 3 insecticides are ideal agents to control cherry drosophila, it is recommended that 60 g/L of spinetoram SC at 30-40 mg/L, 5% of emamectin benzoate WG at 6.25-8.33 mg/L and 10 billion spores/mL of empedobacter brevis SC at 1.11×10~7-1.25×10~7 spores/mL are sprayed alternately in the period of cherry fruit expansion and fruit color change to delay the onset of resistance.
