摘要
利用管氏肿腿蜂进行了防治锈色粒肩天牛幼虫的试验,结果表明：锈色粒肩天牛幼虫的寄生死亡率可达40%-70%,而且幼虫的寄生死亡率随着放蜂量的增加而提高,按虫蜂比1∶1、1∶5和1∶10分别放蜂,寄生死亡率依次为35.4%、48.3%和68.9%;最佳放蜂时间为8月中旬,此时放蜂的校正寄生率为55.67%,明显地高于7月份和9月份。
The experiment of controlling Apriona swmnsoni using Scleroderma guani was studied. The results showed that the control effect was 40% -70% ,the parasitical death rate of Scleroderma guani on Apriona swmnsoni rose with the increasing of touching Scleroderma guan,and touched with 1： 1,1： 5 and 1： 10,the parastizing infecting death rates were 35. 4% ,48. 3% and 68- 9% respectively. The optimum release wasp time is in the second ten days of August, its parasitic rate of Sderoderma guani to Apriona swmnsoni can reach 55.67% ,which is higher than that in July or September.
