“…OPs and carbamates target acetylcholinesterase (AChE) (EC 3.1.1.7), a key enzyme in the nervous system of both vertebrates and invertebrates. Metabolic OP resistance has been detected directly in some cases by measuring OP metabolism (Voss and Matsumura, 1964) or indirectly by revealing the discrepancies between in vivo resistance and in vitro AChE insensitivity (Zahavi and Tahori, 1970). However, target-site insensitivity seems to be the most common OP resistance mechanism in T. urticae.…”

The two-spotted spider mite Tetranychus urticae Koch is one of the economically most important pests in a wide range of outdoor and protected crops worldwide. Its control has been and still is largely based on the use of insecticides and acaricides. However, due to its short life cycle, abundant progeny and arrhenotokous reproduction, it is able to develop resistance to these compounds very rapidly. As a consequence, it has the dubious reputation to be the"most resistant species" in terms of the total number of pesticides to which populations have become resistant, and its control has become problematic in many areas worldwide. Insecticide and acaricide resistance has also been reported in the ectoparasite Sarcoptes scabiei, the causative organism of scabies, and other economically important Acari, such as the Southern cattle tick Rhipicephalus microplus, one of the biggest arthropod threats to livestock, and the parasitic mite Varroa destructor, a major economic burden for beekeepers worldwide. Although resistance research in Acari has not kept pace with that in insects, a number of studies on the molecular mechanisms responsible for the resistant phenotype has been conducted recently. In this review, state-of-the-art information on T. urticae resistance, supplemented with data on other important Acari has been brought together. Considerable attention is given to the underlying resistance mechanisms that have been elucidated at the molecular level. The incidence of bifenazate resistance in T. urticae is expanded as an insecticide resistance evolutionary paradigm in arthropods.

“…Organophosphates such as chlorpyrifos and dimethoate are still available as acaricides, and although they have proven to be efficient in controlling eriophyid mites like the tomato russet mite A. lycopersici and the litchi gall mite Aceria litchii (Keifer) in the past, their activity was doubtful on economically important species such as citrus rust mite P. oleivora and apple rust mite A. schlechtendali (Childers et al 1996). Resistance to organophosphates in spider mites was one of the first characterised cases of arthropod resistance (Smissaert 1964;Voss and Matsumura 1964). Since then, numerous reports have investigated resistance of spider mites to this group of chemicals, and Tetranychus urticae Koch has developed resistance to more than 30 organophosphates in more than 40 countries (Georghiou and Lagunes-Tejeda 1991, Arthropod Pesticide Resistance Database).…”

The superfamily of the Eriophyoidea is a large and diverse group of mites, including a number of species of economic importance, mainly on perennial plants in agriculture and forestry. This review focuses on the economic importance and pest status of this group of mites, with emphasis on some genera. The available acaricide portfolio is reviewed and the influence of EU legislation policy on the sustainable control of Eriophyoidea is investigated. Possible generic guidelines for sustainable control and resistance management with special reference to the European situation are discussed. Recent advances in biological and integrated control of eriophyid mite pests and the implementation of these techniques in crops are explored. Furthermore, the relevance of studies on behaviour, epidemiology and diagnostics in general terms and as a strategic necessity is pointed out.

“…A causal relationship between insensitive AChE and OP-resistance has been found in one other acarine species, T. urticae, by Smissaert (1964) and Voss and Matsumura (1964). Stone (1968b) has found that the low brain AChE level in the Ridgelands strain is controlled by a single, incompletely recessive gene.…”
