Chromosomal location of the amplified esterase genes conferring resistance to insecticides in Myzus persicae (Homoptera: Aphididae)

, 1995
A genomic probe encompassing most of an esterase gene (E4) that is amplified in insecticide-resistant Myzus persicae was hybridized in situ to mitotic and meiotic chromosome preparations of aphid clones of known esterase type and resistance level ...

Micro-evolutionary change in relation to insecticide resistance in the peach-potato aphid, Myzus persicae [PDF]

, 2010
2. Asexual organisms rely on mutation whereas sexual organisms combine mutation with recombination. 3. Few organisms provide examples of species that are both sexual and asexual, but aphids do. 4.

Behavioural responses of peach potato aphid, Myzus persicae Sulzer (Hemiptera: Aphididae), to entomopathogenic fungi infected conspecifics

Agricultural and Forest Entomology, EarlyView.
Myzus persicae showed no detectable behavioural response to Beauveria bassiana‐colonised agar alone. Aphids spent significantly more time in odour fields containing EPF‐infected conspecifics than healthy aphids, agar or blank air. EPF infection may alter host‐associated odours, suggesting pathogen‐mediated cues could influence aphid behaviour and ...

Volatile organic compounds released from cabbage plants infested with wingless green peach aphid (Myzus persicae) attracts more conspecifics

BACKGROUND: Plants release a diverse array of volatile organic compounds (VOCs) that play a role in interactions with other plants and arthropod herbivores.

Laboratory Evaluation of Some Mineral Oils against Myzus persicae [PDF]

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.

Impact of food scarcity on the foraging dynamics of Eriopis connexa (Germar, 1824) (Coleoptera: Coccinellidae) Impacto da escassez de alimentos na dinâmica de forrageamento de Eriopis connexa (Germar, 1824) (Coleoptera: Coccinellidae)

Agricultural and Forest Entomology, EarlyView.
Starvation duration alters predatory behaviour of Eriopis connexa, affecting aphid consumption and survival dynamics. Increased starvation enhances attack rate, accelerating prey depletion without substantially affecting handling time. Functional response remains type II, with stronger predation under prolonged food deprivation.

Bioassay and field-simulator studies of the efficacy of pymetrozine against peach-potato aphids, Myzus persicae (Hemiptera: Aphididae), possessing different mechanisms of insecticide resistance

, 2002
Twenty-one clones of the peach-potato aphid, Myzus persicae (Sulzer), carrying various combinations of known mechanisms of insecticide resistance were assessed for their response to the new pyridine azomethine compound, pymetrozine, in leaf-dip bioassays.
