| reproductive performance of asexual clones of the peach-potato aphid, ( myzus persicae, homoptera: aphididae), colonising scotland in relation to host plant and field ecology. | the population of peach-potato aphid, myzus persicae (sulzer), in scotland comprises large numbers of a few superclones with much smaller numbers of other clones, and the reason for their differential success has yet to be elucidated. in the current study, the reproduction of lineages derived from these clones was measured by counting the numbers of offspring produced by a one-day-old nymph after 15 days. this was measured on four plant species, including local agricultural hosts and at two diff ... | 2010 | 19941675 |
| the attack of the clones: tracking the movement of insecticide-resistant peach-potato aphids myzus persicae (hemiptera: aphididae). | myzus persicae (sulzer) collected in scotland were characterized for four microsatellite loci, intergenic spacer fingerprints and the resistance mechanisms modified acetylcholinesterase (mace), overproduced carboxylesterase and knockdown resistance (kdr). microsatellite polymorphisms were used to define a limited number of clones that were either fully susceptible to insecticides or possessed characteristic combinations of resistance mechanisms. within these clones, intergenic spacer fingerprint ... | 2005 | 16197569 |
