Modeling temporal trends in aphid vector dispersal and cucumber mosaic virus epidemics in snap bean.
Cucumber mosaic virus (CMV) has become a major limiting factor in snap bean production in the Great Lakes region of North America, and epidemics have occurred more frequently since the soybean aphid, Aphis glycines Matsumura, was introduced. Major aphid vectors of CMV epidemics were identified by statistically relating their temporal dispersal trends to the incidence of CMV. Alates were monitor...
Life history parameters of the ladybird populations, Propylea quatuordecimpunctata (L.) (Coleoptera: Coccinellidae), collected at two locations in Iran (Karaj and Sari) were recorded on two prey species, Aphis fabae Scopoli, 1763 and Aphis gossypii Glover, 1877 (Homoptera: Aphididae). The duration of most developmental stages (egg, first, second and third instar larva...
Factors Influencing Hatchability of Hibernated Eggs of Aphis gossypii GLOVER (Homoptera: Aphididae).
Abstract Aphis gossypii Glover (Hemiptera: Aphididae) is a polyphagous species frequently associated with the presence of sooty mold and viruses lethal to plants. The purpose this work was characterize possible resistance categories cotton genotypes against A. gossypii. Initially, preliminary test carried out 78 genotypes, 15 which were selected for infestation ability assays determination cumu...
