Abstract:

The biology and morphometrics of Steneotarsonemus spinki Smiley on alternate hosts of rice: Jungle rice (Echinochloa colonum L.) and Nut grass (Cyperus rotundus L.) were studied in laboratory conditions. The average incubation period of S. spinki was 2.75 ± 0.679 days and 2.4 ± 0.476 days on E. colonum and C. rotundus, respectively. The total larval period of S. spinki was 2.5 ± 0.513 and 3.45 ± 0.626 days on E. colonum and C. rotundus. The quiescent period was 0.591 ± 0.202 day and 0.688 ± 0.372 day on E. colonum and C. rotundus, respectively. The male and female longevity of S. spinki was 3.15 ± 1.203 days and 4.05 ± 0.643 days on E. colonum, whereas it was 2.8 ± 0.715 days and 3.7 ± 0.888 days on C. rotundus. The pre-oviposition period was 1 to 2.5 days on E. colonum and C. rotundus. The oviposition periods of S. spinki varied from 0.5 to 2.5 days and 1 to 2 days on E. colonum and C. rotundus, respectively. The post oviposition period of S. spinki was 1 to 2 on E. colonum and C. rotundus. Total life cycle of S. spinki male occupied 8.70 ± 1.316 days and 8.95 ± 1.342 days in case of E. colonum and C. rotundus. Female required 9.60 ± 1.486 days and 9.85 ± 1.313 days on E. colonum and C. rotundus, respectively.
