Abstract

Two spotted spider mite (Tetranychus urticae) is a pest that causes damage to 250 plants and over 1,400 species. It rapidly develops resistance to acaricides due to its high reproductive capacity, inbreeding, asexual reproduction, and short life cycle, resulting in frequent occurrences per year. Resistance mechanisms include inhibition of AChE, sodium channel modulator, glutamate-gated chloride channels allosteric, mite growth inhibitors, inhibitors of acetyl CoA carboxylase, inhibition of mitochondrial ATP synthase, inhibition of mitochondrial complex I, II, III, and electron transport. The mechanism of action varies depending on acaricides used. making it necessary to confirm the appropriate treatment when spraying chemicals. Toxicity bioassay methods to evaluate the development of acaricide resistance include slide dip, leaf dip, leaf disc, topical application, vial leaf dip, and spray potter tower. Recently, molecular diagnostic methods have also been developed, but these methods do not depend on the pest species or developmental stage. Since accuracy varies depending on acaricide, it is essential to find the method that best suits your field. To effectively manage resistant two spotted spider mites, acaricides with a low risk of resistance development can be used. Additionally, biological control methods utilizing natural enemies like Phytoseiulus persimilis and Neoseiulus californicus are suggested. Eco-friendly approaches, including the use of plant extracts and essential oils such as neem and pyrethrum, are also recommended. It is essential to explore various factors for integrated management to reduce the reliance on chemical applications.
