Maria Riga et al.
Scientific reports, 7(1), 9202-9202 (2017-08-25)
The mechanisms underlying insecticide and acaricide resistance in insects and mites are often complex, including additive effects of target-site insensitivity, increased metabolism and transport. The extent to which target-site resistance mutations contribute to the resistance phenotype is, however, not well

Experimental & applied acarology, 27(3), 181-193 (2003-02-21)
Resistance to clofentezine was identified in four populations of the European red mite, Panonychus ulmi (Koch), from apple orchards in Ontario after ca. 5 years use. Resistance was expressed at high levels (> 2000-fold at the LC 50) to clofentezine

Method-performance studies were conducted for the notified revised analytical method of clofentezine. Clofentezine spiked in azuki beans, apple, orange, banana, grape, tea powder and tea extract at the level of 0.2 microgram/g (2 micrograms/g for tea) was analyzed in replicate

Sublethal effects of the growth inhibitor, clofentezine, on life-table parameters of Tetranychus urticae Koch females treated at different developmental stages with a concentration causing >90% mortality were investigated. Females which survived treatment as 'early' (0-24 h old) eggs produced 12%

Food additives and contaminants, 6 Suppl 1, S33-S39 (1989-01-01)
Metabolic and kinetic data on pesticides are now becoming an important part of the toxicological dossier required for product registration. In this paper the approach by one agrochemical company to generating such data is discussed. Metabolic data for the acaricide
