与几种真菌一起，植物寄生线虫Ditylenchus destructor是对日本大蒜产区造成严重损害的病原体之一。因为D.除此之外，由于毁灭者是植物和真菌的饲养者，其侵染可能受到大蒜植物相关真菌的影响，并通过控制这些真菌来抑制。然而，目前还没有关于线虫和真菌之间相互作用的信息。麦长管蚜是一种非寄生性食菌线虫，对植物病原真菌具有潜在的控制作用。假设大蒜伴生真菌与D. destructor，A. avenae可能有助于抑制D.破坏者通过真菌控制。研究了大蒜真菌与D.析构函数以及D. destructor和A.对这些真菌进行了防治试验，并对麦长管蚜D.析构函数使用A.燕麦大多数分离自大蒜的真菌对D. destructor和A.燕麦，允许其繁殖。同时接种D. destructor和A.燕麦在菌垫上的繁殖效果较好。avenae比D. destructor对几种真菌的抑制作用以及D.自毁程序传播速率同样，盆栽试验涉及同时接种A。avenae对D.析构函数传播D. destructor被大蒜伴生真菌吸引、取食和繁殖，表明这些真菌可能是D.在大蒜田线虫的为害中起着重要作用。此外，A.燕麦在真菌上的繁殖能力以及对D.析构函数表明A.麦长管蚜是一种很有潜力的防治大蒜伴生真菌和D.析构函数
Together with several fungi, the plant parasitic nematode Ditylenchus destructor is among the pathogens that cause serious damage to garlic production areas in Japan. Because D. destructor is a plant and fungal feeder, its infestation may be influenced by the garlic plant-associated fungi and suppressed through control of those fungi. However, no information is currently available regarding the interaction between the nematode and the fungi. Aphelenchus avenae is a non-parasitic fungivorous nematode, which can potentially control plant-pathogenic fungi. Assuming an interaction between the garlic-associated fungi and D. destructor, A. avenae may contribute to suppress D. destructor through fungal control. The present study investigated the interaction between the fungi isolated from garlic and D. destructor as well as the preference of D. destructor and A. avenae for those fungi, aiming to control the fungi and D. destructor using A. avenae. Most fungi isolated from garlic attracted both D. destructor and A. avenae, allowing their propagation. In vitro experiments involving the simultaneous inoculation of D. destructor and A. avenae on a fungus mat showed a better propagation of A. avenae than D. destructor on several fungi as well as the suppression of the D. destructor propagation rate. Similarly, pot experiments involving the simultaneous inoculation of A. avenae showed suppression of D. destructor propagation. The fact that D. destructor is attracted to, feeds on, and propagates on garlic-associated fungi suggests that those fungi can be a host for D. destructor, playing an important role for the nematode's infestation of garlic fields. Further, A. avenae propagation on the fungi and its ability to suppress the propagation of D. destructor suggest that A. avenae is a potential biological agent to control both the garlic-associated fungi and D. destructor.
