Citrus Root Weevil Control on Citrus, 1988
Insecticide and Acaricide Tests, 1989Abstract The experiment was conducted with a completely randomized block design of 2 trees/plot and was replicated 4 times. All treatments were applied with a John Bean sprayer at 300 psi to run-off. Wild adult weevils collected from the adjacent plantings were placed in screen limb bags (5 weevils/bag) which were attached to treated ...

Control of Root Weevils in Strawberry Plantings
Journal of Economic Entomology, 1959Lindane, aldrin, heptachlor, and chlordane were tested for the control of three species of Brachyrhinus strawberry root weevil. Each insecticide was mixed with soil low in organic matter before setting the plants. Each of the first three was applied at the rates of 2½, 5, and 10 pounds actual per acre; the chlordane at 5, 10 and 20 pounds.

Elevated CO2 and aboveground–belowground herbivory by the clover root weevil
Oecologia, 2009Predicted increases in atmospheric carbon dioxide (CO(2)) concentrations are expected to increase primary productivity in many terrestrial ecosystems, which could lead to plants becoming N limited. Studies suggest that legumes may partially overcome this by increasing biological nitrogen fixation.

Recent Developments in Strawberry Root Weevil Control
Journal of Economic Entomology, 1927The Strawberry Root Weevil (Brachyrinus ovatus L.) is the most serious pest of strawberries on the Pacific Coast. The history of past efforts to arrive at a satisfactory method of control is reviewed. Previous methods suggested by different workers have been cultural methods, including suitable crop rotation and the use of weevil proof barriers.
