Cotton produces insecticidal terpenoids that are induced by tissue-feeding herbivores. Damage by Heliothis virescens caterpillars increases the terpenoid content, which reduces the abundance of aphids. This effect is not evident in Bt-transgenic cotton, which is resistant to H. virescens. We determined whether induction of terpenoids by caterpillars influences the host quality of Aphis gossypii...

Finding a new source of resistance is important to reduce the use synthetic pesticides, which can meet global need suppressing pollution. In this study, eight eggplant cultivars Aphis gossypii was evaluated. Results current study highlighted that cultivar Long-Green has very strong after 14 days post infestation whereas Pearl-Round and White-Casper were susceptible. The rest tested (Green-oblon...

Diaphorina citri Kuwayama (Psyllidae: Hemiptera) and Aphis gossypii Glover (Aphididae; are destructive sap-feeding pests of citrus cotton, respectively. This study assessed the toxicity potential indigenous flora Soon valley surrounding salt range (Punjab, Pakistan) against D. A. gossypii. Among acetone extracts 40 plant species, Mentha longifolia (L.) Huds., Melilotus officinalis Pall., Nerium...

pepper plant capsicum annuum l. has great nutritional value and many pharmaceutical properties but its sensitivity to pests such as aphis gossypii glover, especially in drought stress conditions, has limited its production. to evaluate the effect of drought stress on the population and damage rate of this pest in greenhouse condition, four moisture treatments including; full irrigation, 15, 30 ...

life table gives the most comprehensive explanation of the survivorship, development, and reproduction of a population. the life table parameters of an aphidophagous midge, aphidoletes aphidimyza were studied on different densities (5, 10, 20, 40, 60, 80) of third instar nymphs of aphis gossypii as prey in a growth chamber (25 ± 1 °c, 70 ± 5% rh and a photoperiod of 16l: 8d h). the pre-oviposit...

Aphids (Hemiptera: Aphididae) have been the focus of several studies with respect to their interactions with inherited symbionts, but bacterial communities of most aphid species are still poorly characterized. In this research, we used bar-coded pyrosequencing to characterize bacterial communities in aphids. Specifically, we examined the diversity of bacteria in two obligately parthenogenetic a...

Aphidius transcaspicus Telenga, a mealy plum aphid (Hyalopterus pruni Geoffroy) parasitoid from the Mediterranean, was recently introduced into Hawaii for control of invasive aphids. Under laboratory conditions the parasitoid successfully attacked several important aphid pests in Hawaii, including the melon aphid Aphis gossypii Glover, the banana aphid Pentalonia nigronervosa (Coquerel), the gr...

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...
