| dc.description | Nymphs of Myndus crudus Van Duzee (Homoptera : Cixiidae), a vector of Lethal Yellowing (LY) of palms, develop in the root zones of grasses. Management of grasses under coconuts is a potential method of suppressing population of this insect vector. To identify grasses unfavorable as hosts of M. crudus, six species of grasses grown in containers were exposed to field collected adult M. crudus. Hosts suitability was measured by the relative degree of colonization of the roots of these grasses by immatures, compared to roots of Stenotaphrum secundatum (Walt.) Kuntze, a know host of M. crudus immatures. Of the grasses tested, Hyparrhenia rufa (Nees) Stapf. proved to be the poorest breeding host of this insect, and may prove useful as a potential ground cover in coconut plantations to reduce the incidence of the vector and thus the spread of LY. | |
