점박이응애(Tetranychus urticae)는 250과 1400여종의 식물에 피해를 주고 있는 해충으로 높은 번식력, 근친 교배, 무성생식, 짧은 수명주기 로 년간 발생회수가 많기 때문에 약제에 대한 저항성이 빠르게 발달하는 종이다. 저항성 기작은 AChE 저해, sodium channel modulator, glutamate gated chloride channels allosteric, mite growth inhibitors, inhibitors of acetyl CoA carboxylase, mitochondrial ATP synthase 저 해, mitochondrial complex I, II, III, 그리고 electron transport 저해 등이 있으며 약제에 따라 작용기작이 다르므로 약제살포 시 확인이 필요하 다. 약제저항성 발달을 평가하는 독성시험방법으로 slide dip, leaf dip, leaf disc, topical application, vial leaf dip, spray potter tower, leaf vial dipping 등이 있으며 최근에는 분자학적 진단법 등도 개발되어 있으나 이들 방법은 해충 종이나 발육상태에 약제에 따라 정확도가 달라지므로 현장 에 가장 맞는 방법을 찾아야 할 것이다. 저항성 점박이응애를 효과적으로 관리하기 위한 방법으로 저항성 위험이 낮은 살응애제(chemical acaricide) 약제 선발, 천적인 칠레이리응애, 사막이리응애를 이용한 생물적 방제, 님, 제충국, 등 식물추출물이나 정유를 활용한 친환경적인 방법 등이 제시되 고 있으며 종합관리를 위한 다양한 요인을 찾아 약제 사용을 줄여 나가야 할 것이다.
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.
