The oriental microhymenopteran wasp, Gryon triatomae Masner, 1975 was reared in eggs of triatomine bugs, including vectors of Chagas' disease. In particular, G. triatomae was maintained for 31 generations in eggs of Triatoma maculata (Erichson). Only one parasite develops in each bug egg and 30 to 40 days are required for completion of development at 24 +/- 1 degrees C. Mean parasitization rate of 7484 eggs of T. maculata, in 54 rearings, was 34.7% with a range from zero to the highest rate of 86.7%. Mated females produce predominantly female progeny (mean sex ratio, 1 male:6.7 females). Unmated females produce parthenogenetic males. The wasp reproduces in fertile eggs, from those recently laid to those with well-advanced bug embryos. Infertile eggs are not usually parasitized. Both sexes survive for one to two weeks unfed, but for several weeks (up to 16 for females) if fed (on honey). Frequent ovipositions may reduce survival. Successful parasitization by females persisted for about three weeks but declined subsequently. Abortions of developing Gryon were usually 10% or less. Brief comparison with other neotropical triatomine species indicates that eggs of Triatoma spp. are susceptible to G. triatomae; Panstrongylus spp. seem relatively poor hosts, and there is little or no parasitization of Rhodnius spp.
东方小型膜翅目黄蜂，格氏锥蝽寄蝇（Gryon triatomae Masner，1975）在锥蝽的卵中饲养，锥蝽包括恰加斯病的传播媒介。特别地，格氏锥蝽寄蝇在黄斑锥蝽（Triatoma maculata，Erichson）的卵中维持了31代。每个锥蝽卵中仅发育出一只寄生虫，在24±1℃下完成发育需要30至40天。在54次饲养中，对7484枚黄斑锥蝽卵的平均寄生率为34.7%，范围从零到最高86.7%。交配过的雌虫主要产生雌性后代（平均性别比为1雄:6.7雌）。未交配的雌虫产生孤雌生殖的雄虫。这种黄蜂在可育卵中繁殖，从刚产下的卵到发育良好的锥蝽胚胎的卵。不育卵通常不会被寄生。雌雄两性在未喂食的情况下可存活一到两周，但如果喂食（蜂蜜）则可存活数周（雌虫可达16周）。频繁产卵可能会降低存活率。雌虫成功寄生可持续约三周，但随后会下降。发育中的格氏锥蝽寄蝇的流产率通常为10%或更低。与其他新热带锥蝽物种的简要比较表明，锥蝽属的卵易受格氏锥蝽寄蝇感染；潘氏锥蝽属似乎是相对较差的宿主，而红猎蝽属几乎没有或完全没有被寄生。
