我们研究了与小蠹树皮甲虫（Cryphalus rhusi）相关的真菌，这种小蠹虫侵染了漆树毒漆树（Toxicodendron vernicifluum）。还评估了真菌在 T 中的致病性。 vernicifluuma 是朝着阐明甲虫对树木造成损害的可能性迈出的一步。从从树枝上长出的成虫中分离出三种真菌，即山田酶菌（Yamadazymasp.）、镰刀菌（Fusariumsp.）和嗜松青霉（Penicillium pinophilum）。其中，Yamadazymasp。似乎是甲虫的亲密伙伴，因为它与研究中使用的所有个体隔离，而其他甲虫的出现频率要低得多。致病性测试表明镰刀菌。造成比阴性对照稍大的病变（2毫米），而Yamadazymasp。没有引起任何症状。我们的结论是C.漆树及其相关真菌不太可能成为严重的害虫。漆树。
We have examined the fungi associated with the scolytid bark beetle,Cryphalus rhusi, which infests the lacquer treeToxicodendron vernicifluum. The fungi were also evaluated for pathogenicity inT. vernicifluumas a step toward clarifying the potential of the beetle for tree damage. Three fungal species, aYamadazymasp., aFusariumsp., andPenicillium pinophilumwere isolated from adult beetles that had emerged from branches. Of these, theYamadazymasp. appeared to be a close associate of the beetle, since it was isolated from all individuals used in the study, while the others were much less frequent. Pathogenicity tests revealed that theFusariumsp. caused slightly larger lesions (by 2 mm) than the negative controls, whereas theYamadazymasp. did not cause any symptoms. We conclude thatC. rhusi, with its associated fungi, is not likely to be a serious pest forT. vernicifluum.
