Experimental infections were produced with the host-specific nematode Heterotylenchus autumnalis, which sterilizes its host, the face fly (Musca autumnalis). The high infection rate achieved (means = 82.5%) was similar for male and female flies. The pupal emergence rate was significantly lower for fly larvae exposed to the nematodes than for unexposed controls. Heterotylenchus-exposed flies had a sex ratio skewed in favor of males. This indicates that in addition to sterilization, H. autumnalis has other deleterious effects on its host. Heterotylenchus autumnalis is therefore a candidate for use as a potential biological control agent of the face fly.
利用宿主特异性线虫秋季异小杆线虫（Heterotylenchus autumnalis）进行了实验性感染，该线虫会使宿主秋家蝇（Musca autumnalis）绝育。所达到的高感染率（平均 = 82.5%）在雄性和雌性家蝇中相似。暴露于线虫的蝇幼虫的羽化率显著低于未暴露的对照组。暴露于秋季异小杆线虫的家蝇的性别比例偏向雄性。这表明除了绝育外，秋季异小杆线虫对其宿主还有其他有害影响。因此，秋季异小杆线虫是用作秋家蝇潜在生物防治剂的候选物种。
