Abstract Insects are often a major obstacle to the successful production of cucurbits. They can severely reduce yield, injure or kill plants, spread disease and adversely affect fruit quality. Spider mites can also be a problem, particularly with glasshouse cucumbers.

Spider Mites Avoid Plants with Predators
Experimental & Applied Acarology, 1999While searching for food, prey can use cues associated with their predators to select patches with a reduced predation risk. In many cases, odours indicate the presence of both food and predators. Spider mites are known to use odours to locate food and mates, but also to avoid interspecific competitors. We studied the response of the two-spotted spider

Pesticide-induced mite outbreaks: pyrethroids and spider mites
Experimental & Applied Acarology, 1988Factors 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.

Acaricide Efficacy on Spider Mite and Spider Mite Predators on Almonds, 1986
Insecticide and Acaricide Tests, 1988Abstract Trees were drip-irrigated, 6-yr-old ‘Nonpareil’ or ‘Carmel’ almond trees, and were located in a commercial orchard near Shatter, Calif. Treatments were assigned according to a randomized complete block design consisting of 8 single-tree replicates that were blocked by almond variety and location. Treatments were applied on 1 and

Mite Vaccinations for Sustainable Management of Spider Mites in Vineyards
Ecological Applications, 1997We 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, 1991Abstract 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.

Insecticide and Acaricide Tests, 1989
Abstract Two acaricide tests were applied to cotton, planted 6 Apr (Shafter, Calif.) and 15 Apr (Five Points, Calif.) with individual plots 16 (Shafter) or 8 (Five Points) rows wide by 150 ft long and replicated 4 times in a randomized complete block design.
