Abstract

NAULT, L. R., W. E. STYER, M. E. COFFEY, D. T. GORDON, L. S. NEGI, and C. L. NIBLETT. 1978. Transmission of maize chlorotic mottle virus by chrysomelid beetles. Phytopathology 68: 1071-1074. Maize chlorotic mottle virus (MCMV) is transmitted by after acquisition. Crushed adult D. virgifera collected from six species of beetles belonging to the family Chrysomelidae: infected fields in Kansas reacted positively with MCMV the cereal leaf beetle (Oulema melanopa), the corn flea beetle antiserum. Two other insects with mandibulate mouth parts, (Chaetocnema pulicaria), the flea beetle (Systenafrontalis), the Japanese beetle (Popillia japonica) and larvae of the the southern corn rootworm (Diabrotica undecimpunctata), black cutworm (Agrotis ipsilon), failed to transmit MCMV the northern corn rootworm (D. longicornis), and the as did three aphid species, and a leafhopper, a planthopper, western corn rootworm (D. virgifera). Both larvae and adults and a whitefly species. of 0. melanopa are vectors; adults transmit virus for 6 days
