- Abstract
The study aimed to record prostigmatid and mesostigmatid non-phytoseiid predatory mites and their association with plants (cultivated and wild) in GKVK campus from Feb. 2022 to Jan. 2023. Mite specimens collected belonged to 12 predatory families (six each from Mesostigmata and Prostigmata) under 26 genera and 39 species. The prostigmatid mite family, Stigmaeidae was more abundant with 54.90 per cent relative abundance and also collected frequently in 10 months period in one year. Among 26 genera recorded, Agistemus genus was more abundant (53.82% relative abundance) and was active almost throughout the year (except April & May). Among 39 species recorded, Agistemus sp. nr. industani was more abundant (32.29% relative abundance). Shannon-Weiner diversity index value for mite families, mite genera and mite species were 1.588, 1.854 and 2.412, respectively. Diversity of mites across 61 host plants of 38 botanical families revealed that family Fabaceae harboured maximum number of mites (174 specimens and 18.13% relative abundance), while family Moraceae harboured seven different mite families with the highest Shannon-Weiner diversity index value of 1.88. Ecological significance of occurrence of non-phytoseiid predatory mites in cropping cum natural forest ecosystem in GKVK is discussed.
