Survey of insects associated with sweet potato, Ipomoea batatas, with water traps, in Ituporanga, Santa Catarina

Insects associated with sweet potato, Ipomoea batatas were surveyed at Ituporanga Experimental Station, EPAGRI S.A., Santa Catarina State, Brazil, from 1991 to 1994. Astylus variegatus Germ. (Coleoptera: Dasytidae) and Chaetocnema apricaria Suffr. (Coleoptera: Chrysomelidae) were abundant throughout the crop cycle. The complex of Homoptera (Aphididae: Pemphigida e and Cicadellidae), Diabrotica speciosa Germ., and Typophorus nigritus versutus Lef. (Coleoptera: Chrysomelidae) were constantly present but at lower levels than A. variegatus and C. apricaria. Systena sp. (Coleoptera: Chrysomeliadae) and Lagria villosa Fabr. (Coleoptera: Lagriidae), were casual and occurred at low frequency.
