SCANNING ELECTRON-MICROSCOPY OF ENTOMOPHTHORA-(TRIPLOSPORIUM)-FLORIDANA (ZYGOMYCETES, ENTOMOPHTHORALES) ATTACKING THE SUGI SPIDER-MITE, OLIGONYCHUS-HONDOENSIS (ACARINA, TETRANYCHIDAE)

The surface structure and the function of conidium and anadhesive spore of Entomophthora (Triplosporium) floridana attacking Sugi spider mite were studied by scanning electron microscopy (SEM). Anadhesive spore showed corrugated surface and attaching sac which adhered to body surface of the mite. The conidium had textured surface which differed from smooth surface of Carner's E. sp. near floridana. Flattened conidium supported vertically anadhesive spore on slender capillary tube. Anadhesive spore was considered as an aerial organ for attachment. Resting spores which filled mites had smooth surface. © 1979, JAPANESE SOCIETY OF APPLIED ENTOMOLOGY AND ZOOLOGY.
