Melon aphid (<i>Aphis gossypii</i>) resistance to pesticides

Response of the melon aphid, Aphis gossypii, to host- plant resistance: evidence for high adaptive potential despite low genetic variability

In agrosystems, pests are submitted to strong human-imposed selective pressures to which they sometimes adapt rapidly, either through selection of genotypes resulting from mutation and ⁄or recombination events, or through phenotypic plasticity. Understanding how insects respond to such selective pressures is of great importance for sustainable pest management strategies, such as the use of resi...

Evaluation of wheat (triticum SPP.) resistance to the russian wheat aphid (diuraphis noxia mordvilko)

the toxicity of acetamiprid, dicholorvos and azadirachtin pesticides on melon aphid, aphis gossypii glover and lysiphlebus fabarum marshall

cotton aphid, aphis frangulae gossypii glover, is a major pest of cucumber in iran. one of the important parasitoids playing role in population control of this pest in the fields and greenhouses is lysiphlebus fabarum marshall. in this study, we investigated sensitivity of different instars of cotton aphids and pupal stage of l. fabarum to field recommended and half-recommended concentration of...

Categorizing sugarcane cultivar resistance to the sugarcane aphid and yellow sugarcane aphid (Hemiptera: Aphididae).

Sugarcane (Saccharum spp.) in Louisiana is colonized by two aphid species, the sugarcane aphid, Melanaphis sacchari (Zehntner), and the yellow sugarcane aphid, Sipha flava (Forbes) (Hemiptera: Aphididae). The main problem associated with M. sacchari is transmission of sugarcane yellow leaf virus, a casual agent of yellow leaf disease whose absence has been added to certification standards for m...

yellow, and even drop. Other symptoms of direct feeding damage include plant stunting, poor pod fill, reduced Since 2000, the soybean aphid (Aphis glycines Matsumura) has pod and seed counts, smaller seed size, and nutrient become a major pest of soybean [Glycine max (L.) Merr.] in North America. In the USA, there are currently no commercial soybean deficiencies resulting in overall yield and q...
