چکیده
Mites family Cheyletidae Leach, 1815 (Acari: trombidiformes) have a worldwide distribution. They occupy a great variety of habitats including nests of birds, mammals or insect colonies as nidicolous predators and some are parasites of wild and domestic animals. Moreover, they can act as predators in stored products and some are free-living mites too. A colony of predatory mites belongs to family Cheyletidae was observed in a survey of Trogoderma granarium Everts, 1898 on ×Triticosecale Wittmack and Triticum aestivum L. in the entomology lab of Razi University, Kermanshah, Iran, in 2018. These mites were identified as Chelacaropsis moorei Baker, 1949 by the second author. They were reared on the stored wheat to collect their different stages. This is the first record of this genus and species from Iran. This genus can be distinguished from other cheyletid genera by the palpal tarsus possessing only one fan like seta and having setae similar to the two sickle like setae. Palpal claws of this cheyletid have three teeth. This genus contains seven different species that C. moorei is first described and is type species. This species can be recognized from other species of this genus by the absence of ahysterosomal shield and having hair like h setae. Males are polymorphic and emerge in two different shapes. The predatory behavior of the mite was observed on T. granarium and Acarus siro L. eggs in the colony during current survey and it was proved with some experiments under laboratory conditions. Feeding on broken seeds of wheat was observed in the absence of prey eggs in the colony. C. moorei was previously recorded from United States, Egypt, Thailand, India, West Bengal, and Japan, mostly from tropical and subtropical regions and as the predator of acarid and eriophyid mites as well as small insects on different stored products or in relation with nests. This cheyletid mite is known as a biological control agent on storage pests in the grains or onion and garlic bulbs.There are reports of skin lesions of man caused by C. moorei in Japan. More studies are needed to use C. moorei in the management programs of stored products.
