From 1998 to 2003, beetles and crickets infected with hairworms were collected from 4 localities within the Hanford Nuclear Site and the Hanford Reach National Monument, located in a shrub-steppe region of Washington State along the Columbia River. Infected hosts comprised 6 species of carabid beetles within 5 genera and 2 camel crickets within 1 genus; all are newly documented insect-nematomorph associations. A large proportion of the infected hosts (48%) were collected from a single site during a single collecting period. Of the 38 infected hosts, 32 contained a single worm, 4 hosts contained 2 worms, and 2 hosts contained 3 worms. Five of the hosts with multiple infections contained at least 1 male and 1 female worm. Camel crickets were infected with Neochordodes occidentalis while carabids were infected with an undescribed species of Gordionus . As the majority of hairworms are collected in the post-parasitic adult phase, host data and hairworm-arthropod associations remain poorly documented and our work adds new data to this area of nematomorph biology.
1998年至2003年期间，在位于华盛顿州哥伦比亚河沿岸灌木草原地区的汉福德核设施和汉福德河段国家纪念区内的4个地点，采集了感染铁线虫的甲虫和蟋蟀。受感染的宿主包括5个属的6种步甲科甲虫和1个属的2种穴居蟋蟀；所有这些都是新记录的昆虫与线虫形态生物的关联。很大一部分受感染的宿主（48%）是在一个采集期内从一个地点采集到的。在38只受感染的宿主中，32只体内有1条线虫，4只宿主体内有2条线虫，2只宿主体内有3条线虫。5只多重感染的宿主中至少有1条雄虫和1条雌虫。穴居蟋蟀感染了西方新索线虫，而步甲则感染了一种未描述的戈尔迪线虫属物种。由于大多数铁线虫是在寄生后的成虫阶段采集到的，宿主数据和铁线虫与节肢动物的关联仍然记录不足，我们的工作为线虫形态生物学这一领域增添了新的数据。
