Survey was conducted in mid-hills of Himachal Pradesh during 2011-2012 to study the mite diversity in 16 different vegetables and ornamental crops. These ecosystems were surveyed to collect the prey and predatory mites at different locations. A total of 32 species in 15 genera and 7 families were observed during this study, out of which 6 species were of phytophagous mites belonging to 2 genera and 2 families, whereas 26 species were of the predatory mites belonging to 13 genera and 5 families. Among phytophagous mites, three species viz. Tetranychus urticae Koch, T. ludeni Zacher, T. hypogeae Gupta were most commonly found and recorded on different crops. Among predatory mites, 4 genera viz. Amblyseius, Euseius, Neoseiulus and Amblydromella were most common. Maximum numbers of predatory mite species were recorded on rose, cucumber and brinjal. Five genera of predatory mites viz. Paraphytoseius, Pennaceius, Typhlodromips, Typhlodromalus and Lasioseius were the new record in the state.
