摘要
近年来,桑虎天牛在桑园的危害日趋严重,为搞好桑虎天牛的综合防治,进行了室外小区防治试验。结果表明,施药方法以蛀孔中注射药剂后用黏土堵塞蛀孔效果较好,以塞入醮药棉球次之;药剂中以辛硫磷、毒死蜱较为敏感;施药浓度以200倍稀释液较为适宜,稀释倍数过大,防治效果下降,过小则影响新植苗木生长。配合农业防治措施,在约7 hm2桑园中,有效地控制了桑虎天牛的危害。
Xylotrechus chinensis Chevrolat caused increasing damage to mulberry trees in recent years.A field test was conducted to study the integrated control method on Xylotrechus chinensis chevrolat.The result showed that the best method was blocking every hole with mud after injecting medicaments into the pest holes,then inserting cotton pellet into the pest holes with medicaments.Phoxim and chlorpyrifos were found to be more effective.The suitable ratio of applying pesticide was 200.The control effect would be reduced if the ratio was too high,while the growth of new plants would be affected if the ratio was too low.Together with agricultural control method,Xylotrechus chinensis Chevrolat in 7 hm2 mulberry garden was controlled effectively.
