S. Naranjo ; H. Flint ; T. Henneberry | 1996We used an empirical relationship to develop models for estimating and for classifying the population density of adult Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) in cotton based on the proportion of infested leaves. We examined models b[...]article/chapitre/communication
1. Datura wrightii Regel (Solanaceae) is polymorphic with regard to trichome type. Some plants are densely covered with short, non-glandular trichomes, whereas other plants in the same populations possess glandular trichomes that excrete a stick[...]article/chapitre/communication
L. Nault | 1997This review focuses on the more important arthropod vectors of plant viruses, 4 families of homopterans (aphids, whiteflies, leafhoppers, and delphacid planthoppers), thrips, chrysomellid beetles, and, among the acarines, the eriophyid mites. Mo[...]article/chapitre/communication
A. Tonhasca ; J. Palumbo ; D. Byrne | 1994Early season infestations of the sweet potato whitefly, Bemisia tabaci (Gennadius), on cantaloupes, Cucumis melo L., were determined by counts of the number of adults per leaf in fields near Yuma, Arizona. We used these data to develop binomial [...]ouvrage
