摘要:

利用白蜡吉丁肿腿蜂和管氏肿腿蜂对锈色粒肩天牛低龄幼虫(1~3龄)、花绒寄甲对中老龄幼虫(3龄末—老熟幼虫)和蛹进行防治试验。结果表明:林间释放白蜡吉丁肿腿蜂和管氏肿腿蜂在蜂虫数量比为5:1时,释放25天后锈色粒肩天牛低龄幼虫的平均虫口退减率分别为14.84%和12.57%;锈色粒肩天牛中老龄幼虫和蛹期按天敌与害虫数量3:1和10:1的比例分别释放花绒寄甲成虫和卵,释放30天后锈色粒肩天牛的平均虫口退减率分别为46.50%和38.63%;释放花绒寄甲60天后平均虫口退减率分别为60.00%和52.67%。根据解剖释放花绒寄甲成虫的样木所得到的防治效果调查数据,得出4种估测实际寄生率的回归方程,以一元二次函数方程相关系数最高。在天敌释放后连续3年的防治效果调查表明,花绒寄甲对锈色粒肩天牛具有良好的持续防治作用,表明利用肿腿蜂和花绒寄甲可有效防治锈色粒肩天牛这一重大园林害虫。

Abstract:

In this study, three parasitoid insect species were applied for controlling Apriona swainsoni (Longhorn beetle). Sclerodermus pupariae and S. guani (Hymenoptera: Bethylidae) were released to A.swainsoni young larvae (1st-3rd instar) with a 5 :1 ratio, and Dastarcus helophoroides (Coleoptera: Bothrideridae) in A.swainsoni middle-aged to mature larval and pupal stages. The results showed that the average decline of the young larvae population was by 14.84% and 12.57% respectively after releasing S. pupariae and S. guani in 25 days. When releasing adults and eggs of D. helophoroides with parasitoid-host numbers ratio 3 :1 and 10 :1 respectively, the mean decline rate of the longhorn beetle larvae population was by 46.50% and 38.63% in 30 days; and the average decline rate was 60.00% and 52.67% respectively in 60 days. Based on the data of the controlling effects by cutting and splitting the tested trees, four equations were built to evaluate the actual parasitism rate of D. helophoroides, and among them the quadratic function showed the highest correlation coefficient. Additionally, an investigation on the sustainable control impact was carried out for three years after the parasitoids were released and the result showed that D. helophoroides exerted a sustainable control effect on A. swainsoni. The present study indicates that the three parasitoids could be used to effectively control the longhorn beetle.
