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

open access: yesPest 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 ...

Breeding cold‐tolerant Orius laevigatus lines improves thermal tolerance and body size: implications for biological control

open access: yesPest Management Science, EarlyView.
Biological control agents performance is influenced by temperature. Two cold‐tolerant lines of O. loevigatus were developed, improving their fitness at both low and high temperatures, offering advantages far augmentative biological control. Abstract BACKGROUND The performance of biological control agents (BCAs) is strongly influenced by environmental ...

How effective are entomopathogenic nematodes for vine weevil (Coleoptera: Curculionidae) biological control? A meta‐analysis

open access: yesPest Management Science, EarlyView.
Entomopathogenic nematodes provide reliable biological control of vine weevil larvae, reducing populations by 63% on average. All five tested species are effective, with temperature (18–30 °C) being the strongest predictor of success. Abstract BACKGROUND Vine weevil (Otiorhynchus sulcatus) is a globally important pest of soft fruit and ornamental crops

Potential of endophytic Beauveria bassiana against Coraebus (Coleoptera: Buprestidae) oak borers

open access: yesPest Management Science, EarlyView.
This study demonstrates that an endophytic, oak‐associated strain of Beauveria bassiana exhibits adaptations to Quercus plants and potential against Coraebus boring beetles, supported by distinctive biological traits. Abstract BACKGROUND Oak borers in the genus Coraebus, including the bark‐ and the wood‐boring beetles C. florentinus and C. undatus, are
