The properties of a carboxylesterase from the peach-potato aphid, Myzus persicae (Sulz.), and its role in conferring insecticide resistance.
Carboxylesterases from different strains of Myzus persicae were examined to try to understand their contribution to insecticide resistance. Preliminary evidence that they are involved comes from the good correlation between the degree of resistance and the carboxylesterase and paraoxon-degrading activity in aphid homogenates. Furthermore the carboxylesterase associated with resistance could not...
متن کاملMolecular evidence that insecticide resistance in peach-potato aphids (Myzus persicae Sulz.) results from amplification of an esterase gene.
cDNA clones for the esterase (E4) responsible for broad insecticide resistance in peach-potato aphids (Myzus persicae Sulz.) were isolated and used to study the molecular basis of resistance. Increased esterase synthesis by resistant aphids was found to be associated with amplification of the structural gene for the esterase (E4 or its closely related variant, FE4), the degree of amplification ...
متن کاملMyzus persicae Sulzer aphid contains oxylipins that
Oxylipins are oxygenated fatty acids and their derivatives that play key roles in response to stress. They are widespread in many organisms including mammals or plants but are unknown in arthropods. In this study, we identified oxylipins in Myzys persicae Sulzer aphids reared on Vicia faba L. plants. Further experiments based on: (i) Radiolabelled substrate incubation with aphid extracts, and (...
متن کاملIsolation and Characterization of Novel Cyclotides from Viola hederaceae
Based on a newly established sequencing strategy featured by its efficiency, simplicity, and easy manipulation, the sequences of four novel cyclotides (macrocyclic knotted proteins) isolated from an Australian plant Viola hederaceae were determined. The three-dimensional solution structure of V. hederaceae leaf cyclotide-1 (vhl1), a leaf-specific expressed 31-residue cyclotide, has been determi...
متن کاملIntegrated Field Management of Aphids (myzus Persicae Sulz. and Aphis Gossypii Glov. Together) on Potato (solanum Tuberosum L.) Using Bio-pesticides
Potato (Solanum tuberosum L.) is cultivated in India in a commercial scale and this crop is susceptible to various insect pests of which aphids (both Myzus persicae Sulzer and Aphis gossypii Glover) cause heavy damage especially by spreading virus diseases. Studies were made to evaluate efficacy of extracts from plants such as Pongamia pinnata L. and Nicotiana tabacum L. and Polygonum hydropipe...
