abstract
The biology of T. putrescentiae was carried out on ten different types of broken grains, i.e. groundnut, wheat, rice, bajra, sorghum, black gram, pigeon pea, kabuli gram, green gram and white urd dal. The total developmental period was shortest when acarid mite fed on broken groundnut (14.98 ± 1.42 days) and the oviposition period was highest (18.77 ± 1.78 days), when reared on broken groundnut and it was followed by broken grains of wheat (15.36 ± 1.19 days). The life span of female acarid mite was maximum when fed on broken groundnut (41.50 ± 2.94 days) whereas the highest number of eggs was laid by the females reared on broken groundnut (106.71 ± 5.49 eggs /female).
