To understand the diversity of the gut microbes of Chinese white wax scale Ericerus pela, 16S rDNA clone library was constructed to analyze the gut microbes of the female E. pela adults. The results showed that, the gut of E. pela contained abundant of Rickettsia. Gut microbes Arsenophonus and Variovorax were also been identified. And Rickettsia was the main bacteria in gut of E. pela. The phylogenetic analysis of the 16S rDNA showed that, the Rickettsia from E.pela has close relationship with that of pea aphid Acyrthosiphon pisum. PCR amplification was performed using the specific primers for Rickettsia to detect infection in 30 male and 30 female individuals. The result showed that, the infected male and female were 24 and 12 respectively.

白蜡虫脂酰辅酶A还原酶（FAR1）参与了体表蜡泌物的形成过程，为了进一步研究FAR1的功能，通过预测分析基因 far1 编码的蛋白结构，选取亲水性强、特异性好的一段合成多肽作为抗原肽，免疫新西兰大白兔制备多克隆抗体，并以BCA蛋白浓度试剂盒测定抗体浓度，通过SDS-PAGE考马斯亮蓝染色观察纯化抗体的纯度，以ELISA检测抗体效价。结果表明，纯化所得的多克隆抗体纯度高，抗体浓度0.7 mg·mL-1，抗体效价为 1：512 000，为后续FAR基因功能的研究奠定基础。
