Exploration of new natural enemies of the asian longhorned beetle (Coleoptera: Cerambycidae) in China using sentinel host eggs and larvae
Asian longhorned beetle (ALB), Anoplophora glabripennis (Motschulsky) is a polyphagous wood boring pest that attacks many economically important orchard, roadside, ornamental and forest trees (>100 species). Due to the widespread planting of poplars and willows, it has become one of the most serious forest pests in China and the Korean Peninsula. This cerambycid has also invaded North America and Europe. In order to control ALB in China, many techniques have been employed such as forest management, traps, insecticides, and biological control. Prior to this study, two native polyphagous parasitoids, Sclerodermus guani and Dastarcus helophoroides are currently being used throughout China to control ALB, and few other parasitoids have been reported parasitizing ALB. In order to find specialist parasitoids of ALB, the Chinese Academy of Forestry and USDA-APHIS have carried out a biocontrol program in China since 2015 by applying the technique of deploying ALB-infested sentinel logs to attract parasitoids in three different sites of China (Beijing, Shanghai, and Jilin). From 2015 to 2020, our survey detected 12 species of hymenopteran parasitoids attacking sentinel Asian longhorned beetle larvae or eggs, namely, Bracon planitibiae Yang, Cao et Gould, Iphiaulax impostor (Scopoli), Spathius glabripennis sp.nov. (Unpublished), Zombrus bicolor (Enderlein) (Braconinae), Callocleonymus beijingensis Yang, Oxysychus scolyti Yang, Zolotarewskya robusta glabripennis ssp. nov. (unpublished), Zolotarewskya anoplophora sp.nov. (unpublished) (Pteromalidae), Eurytoma morio Boheman (Eurytomidae), Eupelmus urozonus Dalman (Eupelmidae), Sclerodermus guani Xiao et Wu (Bethylidae) and Xorides sp. (Ichneumonidae). Total parasitism by all these parasitoids was 7–16% in Beijing, 4–11% in Shanghai, and 0–0.2% in Jilin Province, among which, Spathius glabripennis sp.nov and Oxysychus scolyti with rates of parasitism are 1-4% and 2-10% respectively.
