The main objective of this work was to investigate the ability of Aphis gossypii and Myzus persicae to transmit Cucumber mosaic virus (CMV) singly and mixed with two potyviruses (Papaya ringspot virus – type W, PRSV-W and Zucchini yellow mosaic virus, ZYMV), Pinto, Z.V.; Rezende, J.A.M.;Yuki,V.A.; Piedade, S.M.S.Ability ofAphis gossypii andMyzus persicae to transmitCucumbermosaic virus in singl...
The use of synthetic insecticides may cause failures in the biological control insect pests due to undesired side effects on natural enemies and rapid evolution insecticide resistance agroecosystems. Residues neurotoxic can interfere with recognition chemical cues used by find pests. We investigated sub-lethal concentrations pyrethroid lambda-cyhalothrin interaction between aphid parasitoid was...
Plants suffer multiple, simultaneous assaults from above and below ground. In the laboratory, pests and/or pathogen attack are commonly studied on an individual basis. The molecular response of the plant to attack from multiple organisms and the interaction of different defense pathways is unclear. The inducible systemic responses of the potato (Solanum tuberosum L.) host plant were analyzed to...
Invasive ant species can have dramatic impacts on native ants, through direct predation and by usurping common resources. Most invasive ants and many native ants use honeydew, produced by phloem-sucking hemipterans. Because colonies of invasive ants can become very large after establishment, these ants may facilitate greater hemipteran trophobiont population growth compared with their sympatri...
Transmission experiments of different isolates of Cucumber mosaic virus (CMV), Watermelon mosaic virus (WMV) and Zucchini yellow mosaic virus (ZYMV) were conducted using established colonies of Aphis gossypii Glover, Myzus persicae (Sulzer), A. fabae Scopoli and A. craccivora Koch as vectors. The transmission procedure used provided an estimate of the virus transmission efficiency for each aphi...
A filamentous 750 to 800 nm long virus was isolated from a fig tree with conspicuous symptoms in Yugoslavia. The virus has a very narrow host range; it was transmitted mechanically only to some Nicotiana species including N. megalosiphon and N. sylvestris. It causes the formation of cylindrical cytoplasmic inclusions in infected Nicotiana cells. The inclusions consist of pin-wheels, scrolls and...
