Insecticide and Acaricide Tests, 1989
Abstract This test was designed to compare new strains of Bacillus thuringiensis with Di-Beta and standard miticides for control of TSSM. Cotton was planted 28 Apr in plots 8 rows wide and 40 ft long in a randomized complete block design with 4 replicates.

Control of Spider Mites on Cotton1
Journal of Economic Entomology, 1964Experiments were conducted on the chemical control of a field population of Tetranychus telarius (L.) on cotton, suspected of being resistant to organophosphorous miticides. Varying degrees of resistance by this spider mite were exhibited to demeton, ethion, carbophenothion, Bidrin® (3 - hydroxy - N, N - dimethyl- cis -croton-amide dimethyl phosphate),

Control of Spider Mites on Cotton, 1981
Insecticide and Acaricide Tests, 1982Abstract Acaracides were applied to Acala SJ-2 cotton planted Apr 5 near Five Points, CA in rows spaced at 40 inches. Individual plots were 8 rows wide and 100 ft long. Treatments were replicated 6 times in a randomized complete block design and applied Jul 14.

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.

Water Spiders and Mites – Chelicerata [PDF]
, 2013 Freshwater mites (Hydrachnidae) (Fig. 117/1) are chelicerates, often of vivid red, yellow or green colour and with an unsegmented body up to 8 mm. Species inhabiting stagnant or slow-streaming waters are round or oval, while those living in fast-flowing waters are more or less flattened. Due to the mucus of unpleasant flavour, secreted by the glands of

Spider mite control and resistance management: does a genome help?
Pest Management Science, 2013The complete genome of the two-spotted spider mite, Tetranychus urticae, has been reported. This is the first sequenced genome of a highly polyphagous and resistant agricultural pest.

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.

Four spider species and the predacious mitePhytoseiulus persimilis (Athias-Henriot) were examined in the laboratory for their capacity to feed on the carmine spider mite,Tetranychus cinnabarinus (Boisduval). The adult females ofChiracanthium mildei L. Koch showed the highest capacity for feeding onT.

Journal of Economic Entomology, 1990
Tetranychus pacificus McGregor, the mode of inheritance of propargite resistance is consistent with the model of control by one major, nearly completely recessive, gene. No extranuclear effects were found, but minor modifying genes appeared to be involved. Some incompatibility between the susceptible (S)and resistant (R) strains of T.
