Effects of extended and repeated exposures to low temperature on mortality of the peach-potato aphid Myzus persicae

, 1994
1. The survival of adult and first-instar Myzus persicae reared at 20-degrees-C and 10-degrees-C was investigated after brief (1 min) exposure in the absence of plant material to temperatures between -5-degrees-C and -25-degrees-C, and extended exposures

Field-simulator studies of insecticide resistance to dimethylcarbamates and pyrethroids conferred by metabolic- and target site-based mechanisms in peach-potato aphids, Myzus persicae (Hemiptera: Aphididae)

, 2002
A range of insecticides was applied at recommended application rates against populations of Myzus persicae (Sulzer) carrying various combinations of three insecticide resistance mechanisms (carboxylesterase-based metabolic resistance and two target-site ...

(E) -beta-Farnesene synthase genes affect aphid (Myzus persicae) infestation in tobacco (Nicotiana tabacum)

, 2012
Aphids are major agricultural pests which cause significant yield losses of the crop plants each year. (E)-β-farnesene (EβF) is the alarm pheromone involved in the chemical communication between aphids and particularly in the avoidance of predation.

The effects of the repellents dodecanoic acid and polygodial on the acquisition of non-persistent, semi-persistent and persistent plant-viruses by the aphid myzus-persicae

, 1982
Few Myzus persicae settled on polygodial (1 g litre-1) or dodecanoic acid (5 g litre-1)-treated leaves and few nymphs were deposited. Polygodial decreased acquisition of the semi-persistent beet yellows virus and the non-persistent potato virus Y and ...

El rol de tres especies acompañantes en el cultivo de lechuga a campo y su efecto sobre la presencia de insectos perjudiciales y beneficos

Semiárida, 2018
Los agroecosistemas modernos son inestables y sus quiebres se manifiestan como rebrotes recurrentes de plagas en muchos sistemas de cultivo. La producción hortícola, no es ajena a esta situación.

The thermal macrophysiology of core and marginal populations of the aphid Myzus persicae in Europe

, 2010
Insects are ectotherms and have limited ability to regulate body temperature above or below ambient and are consequently greatly affected by temperature. The aphid \(Myzus\) \(persicae\) has an extensive distribution throughout Europe from Scandinavia to

Laboratory Evaluation of Some Mineral Oils against Myzus persicae

Bioassays were conducted to determine the impact of mineral oil on the mortality of Myzus persicae (Sulzer) (Hemiptera: Aphididae). Three concentrations of mineral oil i.e., 0.1, 0.5 and 1.0% v/v were used in the studies.

Resistance mechanisms of Solanum species to Myzus persicae

The aphidMyzuspersicae(Sulzer) constitute a threat to potato crops because of their efficiency to transmit viruses. Many wildSolanumspecies have been reported to have resistance to M.persicae . These species represent an important potential source of resistance, which can be used to enhance resistance in crops.
