Mite Growth Inhibitors (Clofentezine, Hexythiazox, Etoxazole) 

Pliytopliagous mites are important pests in many cropping systems worldwide, e.g., fruits, vegetables, grapes, and ornamentals. A major problem in their control is their high reproductive potential and the extremely short life cycle, both of which facilitate rapid resistance development to many acaricides, often after only a few applications. Therefore, the history of spider mite control is a head-to-head 

Many different biochemical targets in mites have been addressed in recent decades for the development of new acaricides [1, 2]. One group of acaricides are known as mite growth inhibitors and are classified in group 10 of the IRAC (Insecticide Resistance Action Committee) mode of action classification scheme (www.irac-online.org). Mite growth regulators such as clofentezine (1), diflovidazin (2) hexythiazox (3) and etoxazole (4) are presented in this chapter, because they share some common characteristics (Fig. 26.2.1). 

The compounds interfere with mite development and show activity against all juvenile stages of mites (eggs, larvae, nymphs) except adults. Cross-resistance occurs between some of these compounds and, therefore, they have been grouped together in the group 10 of the IRAC Mode of action classification scheme mentioned above [3].
