Abstract

Transmission of maize chlorotic mottle virus by chrysomelid beetles.

Abstract

In studies in the USA on the transmission of maize chlorotic mottle virus (MCMV), 14 insect species were tested as potential vectors and it is reported that successful transmission was obtained with 6 of them, namely Oulema melanopus (L.), Chaetocnema pulicaria (Melsh.), Systena frontalis (F.), Diabrotica undecimpunctata Mannh., D. longicornis (Say) and D. virgifera Lec. Both the larvae and the adults of O. melanopus are vectors; adults transmitted virus for 6 days after acquisition. Crushed adults of D. virgifera collected from infected fields in Kansas reacted positively with MCMV antiserum. Two other insects with mandibulate mouthparts (Popillia japonica Newm. and larvae of Agrotis ipsilon (Hfn.)) failed to transmit MCMV, as did 3 species of aphids (Rhopalosiphum padi (L.), Schizaphis graminum (Rond.) and Myzus persicae (Sulz.)), and also Graminella nigrifrons (Forbes), Peregrinus maidis (Ashm.) and Trialeurodes vaporariorum (Westw.).
