三叶斑潜蝇Neochrysocharis Formosa(Westwood)幼虫是三叶斑潜蝇的重要天敌。福尔摩沙中华按蚊的受精品系主要产生雌性后代。经四环素处理的雌性产生雄性后代，这表明在福尔摩沙北部是由微生物诱导的。16S rRNA基因的核苷酸序列测定结果表明，该寄生蜂感染了一种立克次体细菌，这似乎是引起该寄生蜂的原因。虽然类似贝氏立克次体的细菌已被发现与各种生殖障碍有关，但这是首次在昆虫中发现诱导孤雌生殖的立克次体。
The larval endoparasitoid, Neochrysocharis formosa (Westwood), is an important natural enemy of the leafminer Liriomyza trifolii (Burgess) in Japan. The thelytokous strain of N. formosa mostly produces female progeny. Male progeny were produced by females treated with tetracycline, suggesting that microorganisms induce thelytoky in N. formosa. The result of nucleotide sequencing of the 16S rRNA gene indicated that the parasitoid is infected with a Rickettsia bacterium, which appears to be causative of the thelytoky. Although Rickettsia-bellii-like bacteria have been found to be associated with various reproductive disorders, this is the first finding of a parthenogenesis-inducing Rickettsia among insects.
