【摘要】 进行白蜡外齿茎蜂Stenocephus fraxini成虫和幼虫防治试验,结果表明:在成虫羽化高峰期喷药防治成虫,2.5%高效氯氟氰菊酯2500倍液,1.8%阿维菌素1500倍液,3%噻虫啉1500倍液速效性好。在幼虫孵化初期灌根防治幼虫,25%噻虫嗪1000倍液和20%呋虫胺2000倍液防效最好;打孔注药防治幼虫,5%和10%吡虫啉原液、5%啶虫脒原液防效最好;毒死蜱不适宜于打孔注药使用。更多还原

【Abstract】 Experiments on adult and larval control of Stenocephus fraxini were carried out in the field. The results showed that 2500 times 2.5% beta-cyhalothrin EC, 1 500 times 1.8% avermectin EC and 1 500 times 3% thiamethoxazole microcapsule suspension had good control effect on adults by spraying at the peak stage of adult emergence. In the early stage of larval hatching, the best control effects were obtained by root irrigation with 1 000 times 25% thiamethoxazine water dispersible granules and 2 000 times 20%furosemide soluble granules. The control effect of trunk injection of 5% imidacloprid emulsifiable oil, 10% imidacloprid emulsifiable oil and 5% acetamiprid emulsifiable oil on larvae was very good. 40% chlorpyrifos EC was not suitable for trunk injection.更多还原
