Carpoglyphus lactis (L.) (Astigmata: Carpoglyphidae) is a cosmopolitan mite that is usually found on stored products (dried fruits, dairy ingredients especially cheese, and even processed grains). This causes both direct and indirect damage, As a result of its activity, a suitable substrate for the activity of microorganisms will be provided, which causes unwanted taste and smell. It is also known as alternative prey to produce biological agents (phytoseidae family predator mites).The study examined the impact of the size of dried fruit and their composition as diets on the growth rate of the C. lactis population. To ensure that the dried fruits and objects were free from other factors, all objects and samples were sterilized by autoclave before the exam. The primary population of C. lactis was obtained from Hekmatane Biocontrol Control Company. In this research, a Petri dish was used to raring C. lactis mites, which had a hole in the center for placing the wick (moisture supply). The diets included powdered Apricot (10 micrometer square), crushed Apricot (less than 1 millimeter), a one-piece and dried Apricot compound, a one-piece, broken Apricot mixture, and one-piece Apricot (temperature witness). Each container containing 5 grams of food was placed in the possession of a 100-digit clone, and the containers were placed inside the incubator (1 ± 25 ° C and 5 ± 80 % relative humidity). The weight of each treatment was measured over 10 periods of 12 hours. In this study, Apricot (less than 1 mm) had the highest and lowest growth rate of C. lactis at 250% and powdered Apricot (less than 10 micrometers) at 72% in order. Other growth rates were achieved in the following order: the one-piece and crushed Apricot compound was 208.4%, the saw 192%, and the powdered and one-piece Apricot Compound 148%. The findings of the study emphasize the importance of the size of parts and the health of commodity products in the level of pollution and showed that the Size of Commodity parts influences the rate of damage growth.
