Combined effects of canola plant density and insecticide management strategies on flea beetle abundance, canola defoliation, and yield across the Canadian prairies

Pest Management Science, EarlyView.
Increasing canola plant density reduced flea beetle abundance per plant and increased yield, independent of region or insecticide use, highlighting its potential as a component of integrated pest management. Abstract The crucifer flea beetle, Phyllotreta cruciferae (Goeze), and the striped flea beetle, Phyllotreta striolata (Fabricius) (Coleoptera ...

Intercropping Broccoli‐Basil Reduces Aphid Growth: Spatio‐Temporal Modelling Across Scales and Lab Experiments

Journal of Sustainable Agriculture and Environment
Shifting from conventional to sustainable agriculture demands well‐designed experiments and robust analytical models to evaluate agroecological system performance and resilience. We modelled aphid population dynamics in broccoli monocultures and broccoli‐

Mating success and mating behaviour of the aphid, Myzus persicae (Hemiptera: Aphididae)

European Journal of Entomology, 2002
In this study, aspects of the reproductive performance and behaviour of male Myzus persicae (Sulzer) (Hemiptera: Aphididae) were investigated. We report that males of clones possessing an autosomal 1,3 translocation conferring insecticide resistance show

Transport engineering as a strategy to realize rapeseed's potential as a protein‐rich food

Pest Management Science, EarlyView.
The heavily pesticide‐dependent rapeseed is an under‐utilized protein source for food owing to anti‐nutritional glucosinolates. Transport engineering technology may reduce glucosinolates in seeds while increasing defense in vegetative parts. Abstract Rapeseed is the world's second‐largest oilseed crop, and the low‐value press cake that remains after ...

Efficacy of aqueous extracts from three plants in controlling cabbage aphid [Brevicoryne brassicae L. (Hemiptera: Aphididae)] on field-grown cabbage (Brassica oleraceae L.)

Technology in Horticulture
Cabbage (Brassica oleracea var. capitata L.) crops are frequently attacked by aphids (Brevicoryne brassicae L.) which severely damage cabbage production.

Chemical cues mediating aphid location by natural enemies

European Journal of Entomology, 2008
There is increasing evidence that chemical cues play a pivotal role in host selection by the natural enemies of aphids. We use Vinson's (1976) division of the host selection process into habitat location, host location and host acceptance for both ...

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

Pest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Evaluating astigmatid mites as supplemental food for Macrolophus pygmaeus: contrasting responses between commercial and wild populations

Pest Management Science, EarlyView.
Astigmatid mites provide low‐cost supplemental food for Macrolophus pygmaeus, supporting survival and development, with population‐specific responses and Acarus siro and Carpoglyphus lactis as the most promising alternatives. Abstract BACKGROUND Early establishment of Macrolophus pygmaeus in crops depends on the availability of supplemental food ...
