Abstract:
The biology of coriander aphid, H. coriandri was studies on two varieties of coriander viz. least susceptible coriander variety RCr-436 and most susceptible coriander variety RCr-20 in the Department of Entomology, S.K.N. College of Agriculture, Jobner (SKNAU, Jobner) during Rabi, 2022-23. The first, second, third and fourth instar nymphal period were recorded 1.60±0.42 and 2.25±0.38; 1.75±0.38 and 2.39±0.46; 1.42±0.45 and 2,41±0.38; 1.85±0.29 and 2.41±0.38 days on most susceptible and least susceptible coriander varieties, respectively. The pre reproductive, reproductive and post reproductive periods of adult female were 0.94±0.35 and 1.41±0.38; 6.71±0.99 and 5.81±0.93; 4.29±0.44 and 3.72±0.52 days on most susceptible coriander variety RCr-20 and least susceptible coriander variety RCr-436, respectively. The reproductive potential of adult female was 6.06±0.97 and 4.94±1.29 nymphs per day per adult on most susceptible and least susceptible coriander varieties, respectively. However, during the life span, the reproductive potential of female was 40.65±8.55 and 28.63±8.38 nymphs per adult on most susceptible coriander variety RCr-20 and least susceptible coriander variety RCr-436, respectively. The adult longevity was observed 11.94±1.04 and 10.94±0.98 days on most susceptible coriander variety RCr-20 and least susceptible coriander variety RCr-436, respectively.
