Author(s): BL Naga, Ashok Sharma, SK Khinchi and KC Kumawat
Abstract: The study on seasonal incidence of mite, Tetranychus cinnabarinus (Boisduval) was carried out under field conditions on okra cv. Pusa Sawani in two consecutive years, i.e. kharif, 2004 and 2005. The incidence of mite started in the second week of August in both the years. The population increased gradually and reached to peak in the third week of September with population of 18.78 and18.60 mites/3 leaves in 2004 and 2005, respectively. The population of this pest started to be declined from fourth week of September (10.98 mites /3 leaves) and decreased to the level of 2.66 mites/3 leaves in the second week of October and latter it disappeared from the field in first year. A similar trend of population dynamics was recorded in the second year. The mite population after attaining peak in September gradually decreased with fall in the temperature.
