Comparative evaluation of population dynamics of Tyrophagus putrescentiae Schrank (Acari: Acaridae) on fruiting body of Pleurotus sajor caju at different composition

Abstract

T. putrescentiae population on fruiting body arises from wheat straw based compost revealed that mite number decreased significantly at 36th day. No mites were recorded after 36 days on fruiting body at level of 10, 20 and 30 T. putrescentiae pairs. Similarly, on wheat straw plus calcium sulphate based fruiting body, no mites were recorded after 24, 30 and 36 days. Observations on the average population of T. putrescentiae on fruiting bodies raised from wheat straw based compost revealed that mite number increased significantly at each observation period till 10 days (41.66, 59.00, 83.00 mites/10g ) was recorded at level of 10, 20 and 30 T. putrescentiae pairs. Likewise, observations on the population of T. putrescentiae on fruiting bodies raised from wheat straw plus calcium sulphate based compost recorded a peak in population (45.00, 51.00, 84.00 mites/10g) was recorded at level of 10, 20 and 30 T. putrescentiae pairs.
