Biology of aphid, Myzus persicae (Sulzer) [Homoptera: Aphididae] on cumin (Cuminum cyminum L.) under net-house condition
Italiya LM and Sisodiya DB
An experiment was conducted under net house condition to study the biology of aphid, Myzus persicae (Sulzer) [Homoptera: Aphididae] on cumin(Cuminum cyminum L.) during January, 2016 to February, 2016. It was indicative from the studies on biology of M. persicae on cumin that the average first, second, third and fourth instar nymphal period were 1.68 ± 0.58, 1.84 ± 0.62, 1.56 ± 0.8 and 1.48 ± 0.51 days, respectively. The total nymphal period was varied from 4 to 13 days with an average of 6.56 ± 1.29 days. The pre-reproduction, reproductive and post reproductive periods of M. persicae on cumin were 1.48 ± 0.51, 5.16 ± 1.46 and 1.72 ± 0.61 days, respectively. The female aphid throughout its entire reproductive period produced 18.52 ± 4.27 nymphs at the rate of 4.00 ± 2.23 nymphs/day. The longevity of adult and entire life period was 8.36 ± 1.82 and 14.92 ± 2.00 days, respectively on cumin. During the study period, the average minimum temperature, maximum temperature and relative humidity were recorded as 14.2 °C and 26.95 °C and 59.77 per cent, respectively. The aphid passed two stages i.e., nymph and adult during entire life cycle.
