Intercropping mitigates incidence of the oilseed rape insect pest complex

Pest Management Science, EarlyView.
Intercropping reduces the incidence of the oilseed rape insect pest complex with a significant impact of the direct visual and physical disruption provided by the companion plant. Abstract BACKGROUND Oilseed rape (OSR, Brassica napus) is a major crop requiring numerous phytosanitary treatments.

Root Deformation Reduces Tolerance of Lodgepole Pine to Attack by Warren Root Collar Weevil [PDF]

Environmental Entomology, 2010
Surveys were conducted on regenerating stands of lodgepole pine to determine the relationship between root deformation and susceptibility to attack by the Warren root collar weevil, Hylobius warreni Wood. The total number of trees attacked by H. warreni did not differ between planted and natural trees.

Host plant recognition by the root feeding clover weevil, Sitona lepidus (Coleoptera : Curculionidae) [PDF]

, 2004
This study investigated the ability of neonatal larvae of the root-feeding weevil, Sitona lepidus Gyllenhal, to locate white clover Trifolium repens L. (Fabaceae) roots growing in soil and to distinguish them from the roots of other species of clover and

Edges as ecological filters: Asymmetrical orientation‐specific arthropod activity across forest boundaries

Insect Science, EarlyView.
Moderate retention forestry creates structurally sharp forest edges that act as ecological filters, shaping orientation‐specific activity of ground‐dwelling arthropods. Using drift‐fence pitfall traps, we show that activity aligned with ecotones is more frequent than activity across forest–clearcut boundaries, particularly among detritivores.

Biological role of Nardonella endosymbiont in its weevil host. [PDF]

PLoS ONE, 2010
Weevils constitute the most species-rich animal group with over 60,000 described species, many of which possess specialized symbiotic organs and harbor bacterial endosymbionts. Among the diverse microbial associates of weevils, Nardonella spp.

Effects of soil conditions and drought on egg hatching and larval survival of the clover root weevil (Sitona lepidus)

, 2010
Soil-dwelling insect herbivores are significant pests in many managed ecosystems. Because eggs and larvae are difficult to observe, mathematical models have been developed to predict life-cycle events occurring in the soil.

Refuge by day, forage by night: Diel activity of vine weevil as characterised by smart monitoring

Agricultural and Forest Entomology, EarlyView.
Vine weevil activity was monitored using a Smart trap, which recorded diel refuge‐seeking behaviour. Increasing light intensity triggered refuge seeking behaviour, while lower light intensity induced forage seeking activity. Understanding vine weevil diel activity can enhance early detection, which can improve the effectiveness of integrated pest ...

Tri-party underground symbiosis between a weevil, bacteria and a desert plant. [PDF]

PLoS ONE, 2013
Inhabitants of arid ecosystems face severe nitrogen and water limitations. Inventive adaptations by organisms occupying such habitats are essential for survival.

Root Weevil Control on Red Raspberry, 1996A [PDF]

Arthropod Management Tests, 1997
Abstract Four insecticides were evaluated for control of preovipositional adult BVW in two fields of mature ‘Willamette’ red raspberries in Lynden, WA. Treatments were replicated 4 times on 9 X 30 ft plots arranged in a RCB design. Sprays were applied on 11 Jun along the lower 3 feet of canes with a 2-ft hand-held boom sprayer (100 psi ...

Annual flower strips under the ‘Sweden Blossom’ initiative – how do they perform for pollinators, natural enemies and herbivores?

Agricultural and Forest Entomology, EarlyView.
Pollinator‐targeted annual flower strips increase abundances of pollinators but also natural enemies and herbivores. Natural enemies and herbivores disperse in a taxon‐specific manner into nearby crops. Pest control by ground‐dwellers slightly increases in crop areas near the flower strips.
