The postparasitic stage of Romanomermis culicivorax, applied at dosage rates of 0.025 and 0.05 g/m2, was able to establish, recycle and overwinter in a riceland habit in southern Louisiana. Percent parasitism ranged from 0 to 54.1% during the 22-month study. Parasitism of Psorophora columbiae larvae was significantly greater (P less than 0.05) along levee ditches than in the central portions of the fallow riceland plots on 3 of 4 sampling dates in 1983. As percent parasitism increased within the population of Ps. columbiae located in bioassay containers, the degree of superparasitism also increased.
以0.025克/平方米和0.05克/平方米的剂量施用的嗜蚊罗索线虫寄生后阶段，能够在路易斯安那州南部的稻田环境中定殖、循环和越冬。在为期22个月的研究中，寄生率在0%至54.1%之间。1983年4次采样中的3次，哥伦比亚骚蚊幼虫在堤岸沟渠处的寄生率显著高于休耕稻田地块的中部（P小于0.05）。随着生物测定容器中哥伦比亚骚蚊种群内寄生率的增加，多重寄生的程度也增加。
