Paranosema locustae, an entomopathogen of grasshoppers and locusts, remains the only microsporidium registered as a biocontrol agent. After introductions from North America, it became established in grasshopper communities of Argentina. We measured the infection intensity of field collected, heavily infected male and female adults of individuals belonging to six grasshopper species, five melanoplines (Melanoplinae) (Baeacris pseudopunctulatus, Dichroplus maculipennis, Dichroplus vittatus, Neopedies brunneri, Scotussa lemniscata), and one gomphocerine (Gomphocerinae) (Staurorhectus longicornis). Average spore load among heavily infected grasshoppers ranged from 8.7±0.5×10(7) to 1.1±0.7×10(9). Only females of B. pseudopunctulatus and S. longicornis showed significantly higher spore loads than the males.
东亚飞蝗微孢子虫是一种对蝗虫和蚱蜢具有致病性的昆虫病原体，是唯一一种被注册为生物防治剂的微孢子虫。它从北美引入后，就在阿根廷的蝗虫群落中定殖下来。我们测量了来自野外的、受严重感染的雄性和雌性个体的感染强度，这些个体属于六个蚱蜢物种，五个黑蝗科（Melanoplinae）物种（Baeacris pseudopunctulatus、Dichroplus maculipennis、Dichroplus vittatus、Neopedies brunneri、Scotussa lemniscata）和一个斑腿蝗科（Gomphocerinae）物种（Staurorhectus longicornis）。受严重感染的蝗虫的平均孢子负荷量范围从 8.7±0.5×10(7)到 1.1±0.7×10(9)。只有 B. pseudopunctulatus 和 S. longicornis 的雌性个体的孢子负荷量明显高于雄性个体。
