Spider Mites of Japan: Their Biology and Control
Experimental & Applied Acarology, 2000Spider mite biology and control in Japan were reviewed. Seventy-eight spider mite species of 16 genera (Family Tetranychidae) have been recorded in Japan. Several of the species recently described were separated from a species complex comprising strains with different ecological performance such as host range.

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

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.

Spider-Mite Problems and Control in Taiwan
Experimental & Applied Acarology, 2000Problems with spider mites first appeared in Taiwan in 1958, eight years after the importation of synthetic pesticides, and the mites evolved into major pests on many crops during the 1980s. Of the 74 spider mite species recorded from Taiwan 10 are major pests, with Tetranychus kanzawai most important, followed by T.

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 ...

Photoperiodic termination of diapause in spider mites
Nature, 1977TERMINATION of diapause in the spider mite Tetranychus urticae is considered to depend solely on a period of chilling, the so-called cold rest1–3. The minimal period of chilling required to reactivate a certain percentage of the overwintering population may vary between populations of different geographic origin4.

Insecticide and Acaricide Tests, 1989
Abstract Test plots were established south of Twin Falls, Idaho. The soil type was Portneuf silt loam and the field was surface irrigated. Two tests were conducted using foliar sprays to control TSSM. In both tests the insecticides were sprayed with a CO2 pressurized backpack sprayer at 30 psi and hollow-cone nozzles to apply a broadcast
