Nosema montanae n.sp. (Microsporida: Nosematidae), a parasite from the grasshopper Melanoplus packardii (Orthoptera: Acrididae)



Nosema montanae n.sp. (Microsporida: Nosematidae), a parasite from the grasshopper Melanoplus packardii (Orthoptera: Acrididae)



Journal of Invertebrate Pathology 58(2): 211-218



A new species of Nosema was described from the grasshopper Melanoplus packardii (Orthoptera: Acrididae). Infections appeared to be confined to the fat body. Merogonial stages included uni-, bi-, quadri-, and multinucleate forms. Filaments or chains of meronts or early sporonts appeared to develop from the uncoiling of the multinucleate (usually octonucleate) meronts. Apansporoblastic sporonts were diplokaryotic and disporous. Binucleate sporoblasts were ovocylindrical and measured 2.7 +/- 0.5 micromole by 1.6 +/- 0.3 micromole in fixed. Giemsa-stained preparations. Spores were ovocylindric and measured 3.06 +/- 0.47 micromole by 1.47 +/- 0.16 micromole in fresh preparations and 2.8 +/- 0.5 micromole by 1.4 +/- 0.2 micromole in fixed, Giemsa-stained preparations. Polar tubes occurred in five to seven coils.
