Abstract
Present experiment was carried out on biology and life studies of red spider mite, Tetranychus macfarlanei on okra under laboratory conditions at 30.8-35.10C temperature and 64.5-74% relative humidity at Dr. P. D. K. V., Akola. The total developmental period of T. macfarlanei from egg to adult emergence is recorded less in male (9.0 ± 0.17 days) than female (10.32 ± 0.19 days). T. macfarlanei showed a sexual and arrhenotokous parthenogenesis. Mated female produced a progeny in the ratio 1 male: 4.14 females; whereas, unmated female produced only males. Egg viability was recorded as 93.2 ± 1.17 percent. Adult longevity for male, mated female and unmated female was 11.05 ± 0.99 days, 11.68 ± 1.68 days and 12.45 ± 1.48 days respectively.
