Matrine–Tea Saponin Synergism Involves Suppressed Detoxification and Digestion in a Leaf Beetle

Integrative Zoology, EarlyView.
Tea saponin and matrine showed synergistic toxicity against Plagiodera versicolora. Combined exposure suppressed digestion‐ and detoxification‐related processes, while silencing the trypsin gene Pver105950 and chitinase gene Pver001190 increased larval susceptibility to tea saponin and matrine, respectively.

Antimetabolic effects of plant proteins on homopteran insect pests [PDF]

, 1993
Homopteran insect pests can cause severe economical damage to crop plants by both direct physical means and as vectors of plant viral diseases. They are notoriously difficult insects to control by conventional methods, primarily due to their ability to ...

Evolution of imidacloprid resistance in Myzus persicae in Greece and susceptibility data for spirotetramat

, 2017
BACKGROUND: Myzus persicae s.l. is a major crop pest globally and has evolved resistance to a range of insecticide classes making it increasingly difficult to control in some areas.

Assessing the host plants of the invasive apricot aphid, Myzus mumecola (Hemiptera: Aphididae)

Agricultural and Forest Entomology, EarlyView.
We investigated the host plants of the invasive apricot aphid Myzus mumecola (Hemiptera: Aphididae), an emerging pest species in Europe, by combining molecular and ecological approaches. The winter host plant was confirmed as apricot by both methods.

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 ...

Comparison of the biology of Myzus persicae Sulz. resistant and susceptible to dimethoate

, 1970
SUMMARY Apterous Myzus persicae resistant to dimethoate reproduce for the same length of time as susceptible aphids, but the resistant ones reproduce significantly faster during the first 10 days of adult life (especially during the first 5 days ...
