Pesticide-induced mite outbreaks: pyrethroids and spider mites

Experimental & Applied Acarology, 1988
Factors inducing outbreaks of spider mites (Acari: Tetranychidae) following use of pyrethroid insecticides are reviewed. Differentials in direct toxicity between spider mites and phytoseiid (Acari: Phytoseiidae) predators provide one explanation. Wide variation exists between pyrethroids in their direct toxicity toTetranychus urticae.

Mite Vaccinations for Sustainable Management of Spider Mites in Vineyards

Ecological Applications, 1997
We have successfully released phytophagous Willamette mites into Zinfandel vineyards that have had chronic problems with the economically more damaging Pacific spider mites. These releases induced resistance in the grapevines, causing smaller populations of Pacific mites and higher berry sugar concentrations.

Spider Mite and Predator Mite Test, Michigan, 1990

Insecticide and Acaricide Tests, 1991
Abstract Fifteen rose plants, 3 ft tall, were moated to restrict movement to and from the test plants. Rose plants potted in 3 gal containers were grown in a research greenhouse at MSU. On 5 Sep precounts were made by sampling 10 leaflets from each rose plant. Leaves were collected randomly from each plant.

Twospotted Spider Mite Control, 1976

Insecticide and Acaricide Tests, 1977
Abstract 'U & I Hybrid 8' sugarbeers were planted March 23 at Sunnyside, WA, in Warden silt loam and on April 1 at Quincy, WA, in Timmerman sandy loam. All beets were furrow irrigated. The Quincy plots were 200 ft wide and 600 ft long, and the Sunnyside plots were 150 ft wide and 600 ft long. All treatments were applied by air.

Control of Spider Mites, 1988

Insecticide and Acaricide Tests, 1989
Abstract Acaricides were applied to cotton planted 31 Mar in individual plots 8 (40 inch) rows wide by 150 ft long and replicated 4 times in a randomized complete block design. Application was by high-clearance ground sprayer equipped with drop booms using 3 or 5 hollow-cone TX-6 nozzles/row, depending on plant size, delivering 15 or 25 ...
