2018年,于江苏句容研究了释放花绒寄甲卵对桃园桃红颈天牛的防治效果。结果表明:释放比例为20:1~25:1、25:1~30:1的花绒寄甲释放处理对桃园桃红颈天牛均有明显抑制作用,释放初期湿度是影响其防效的主要气象因子。防治后20d,花绒寄甲释放区释放比例25:1~30:1的处理防效达87.8%。从防治效果和经济成本角度综合考虑,建议加强春秋两季虫情监测,通过分阶段多次释放来提升防效,春季发现少量桃红颈天牛排粪孔时按照20:1~25:1比例释放花绒寄甲,桃红颈天牛虫量较多时按照25:1~30:1的比例释放花绒寄甲;秋季排粪孔有少许虫粪可进行人工捕杀,排粪孔虫粪较多时按照20:1~25:1比例释放花绒寄甲。 |

In 2018, a study was conducted in Jurong, Jiangsu province, on the control effect of the release of Dastarcus helophoroides on Aromia bungii in peach orchard. The results showed that the initial release humidity was the main meteorological factor that affected the control effect, and the release treatment with the release ratio of 20:1~25:1, 25:1~30:1 had significant inhibitory effect on Aromia bungii in peach orchard. After 20 days of control, 87.8% of the control effects were achieved by the treatment with the releasing ratio of 25:1 to 30:1 in the releasing area. From the perspective of control effect and economic cost, it is suggested to strengthen the monitoring of insect situation in spring and autumn, and enhance the control effect by releasing several times in stages. In spring, when a small amount of red necked steaks dung hole is found, the Dastarcus helophoroides is released in a ratio of 20:1~25:1; when the amount of peach aphid is large, the Dastarcus helophoroides is released in a ratio of 25:1~30:1. In autumn, a little insect feces in the defecation hole can be caught and killed manually, and when there is a large amount of feces in the defecation hole, it can release the Dastarcus helophoroides according to the ratio of 20:1 to 25:1. |
