Drosophila paulistorum is a complex of five incipient species which when crossed produce sterile hybrid males and fertile females. Sterility of the male progeny can sometimes be induced by injecting females of one strain (Mesitas) with a homogenate of males of another strain (Santa Marta) or of hybrids between these strains, and then crossing the recipient females to Mesitas males. Filamentous structures have been found in cytoplasmic vacuoles in paragonial cells in males of these and other similar strains and their hybrids. These structures, which contain RNA, possess a helical substructure and resemble certain viruses. Large filamentous structures found in the lumen of the paragonia are also described.
圣保罗果蝇是一个由五个初始物种组成的复合体，这些物种杂交时会产生不育的杂交雄性和可育的雌性。有时，通过给一个品系（梅西塔斯）的雌性注射另一个品系（圣玛尔塔）雄性或这些品系之间杂种的匀浆，然后让接受注射的雌性与梅西塔斯雄性杂交，可以诱导雄性后代的不育。在这些及其他类似品系及其杂种的雄性副生殖腺细胞的细胞质液泡中发现了丝状结构。这些含有RNA的结构具有螺旋亚结构，类似于某些病毒。还描述了在副生殖腺管腔中发现的大型丝状结构。
