Like other members of the tribe Xyleborini, Eichhoff can cause economic damage in the Neotropics. has been found to acquire the laurel wilt pathogen (T. C. Harr., Fraedrich & Aghayeva) when breeding in a host affected by the pathogen. Its role as a potential vector of is under investigation. The main objective of this study was to evaluate three artificial media, containing sawdust of avocado ( Mill.) and silkbay ( Nash.), for rearing under laboratory conditions. In addition, the media were inoculated with to evaluate its effect on the biology of . There was a significant interaction between sawdust species and for all media. Two of the media supported the prolific reproduction of , but the avocado-based medium was generally more effective than the silkbay-based medium, regardless whether or not it was inoculated with . had a neutral or positive effect on beetle reproduction. The pathogen was frequently recovered from beetle galleries, but only from a few individuals which were reared on inoculated media, and showed limited colonization of the beetle's mycangia. Two media with lower water content were most effective for rearing .
与小蠹族的其他成员一样，艾氏小蠹会在新热带区造成经济损失。人们发现，当在受该病原菌影响的寄主中繁殖时，艾氏小蠹会感染月桂枯萎病原菌（T.C. 哈尔、弗雷德里克 & 阿加耶娃）。其作为该病原菌潜在传播媒介的作用正在研究中。本研究的主要目的是评估三种人工培养基，这些培养基含有鳄梨（米勒）和润楠（纳什）的锯末，用于在实验室条件下饲养艾氏小蠹。此外，在培养基中接种该病原菌以评估其对艾氏小蠹生物学特性的影响。对于所有培养基而言，锯末种类与该病原菌之间存在显著的相互作用。其中两种培养基支持艾氏小蠹大量繁殖，但无论是否接种该病原菌，以鳄梨为基础的培养基总体上比以润楠为基础的培养基更有效。该病原菌对甲虫繁殖具有中性或积极影响。病原菌经常从甲虫蛀道中分离出来，但仅从少数在接种培养基上饲养的个体中分离出来，并且在甲虫的菌囊中有有限的定殖。两种含水量较低的培养基对饲养艾氏小蠹最为有效。
