Abundance and Seasonal Activity of Weevils (Coleoptera: Curculionidae) in a Raspberry Plantation and Adjacent Sites in Southern Quebec (Canada). [PDF]
In a raspberry plantation and adjacent sites in southern Quebec, we collected weevils with unbaited pitfall traps and flight interception traps from early May througb late October in 1987-1989. We captured a total of 1592 weevils representing 65 species,

Intercropping mitigates incidence of the oilseed rape insect pest complex
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.

Relationship between water quality, watermilfoil frequency, and weevil distribution in the State of Washington [PDF]
During the summer of 1997, we surveyed 50 waterbodies in Washington State to determine the distribution of the aquatic weevil Euhrychiopsis lecontei Dietz.

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.

Do tissue carbon and nitrogen limit population growth of weevils introduced to control waterhyacinth at a site in the Sacramento-San Joaquin Delta, California? [PDF]
Waterhyacinth (Eichhornia crassipes(Mart.) Solms), is a serious problem in the Sacramento Delta. Two weevil species (Neochetina bruchi Hustache and N. eichhorniae Warner) have been introduced as biological control agents. The purpose of this study was

This Finnish registry study shows that concomitant occupational asthma and rhinitis are common in patients with occupational contact urticaria or protein contact dermatitis, often sharing the same exposure. When evaluating occupational immediate allergy, both skin and airway symptoms should be considered.
