Abstract:
Chrysoperla carnea Stephens (Green lacewing) also known as Aphid lion belongs to family Chrysopidae, order Neuroptera. It is found in most of the environments throughout the world. Experiment was conducted to study the biological parameters of green lacewing Chrysoperla carnea to evaluate the optimum temperature regime under the laboratory conditions. The results showed that maximum mean hatching percentage of Chrysoperla carnea eggs (98.22±0.79) was noted under T6: 290C and minimum mean hatching percentage of Chrysoperla carnea eggs (84.89±0.97) was noted under T7: 310C. Maximum mean newly hatched larvae of Chrysoperla carnea (147.33±1.20) was noted under T6: 290C and minimum mean newly hatched larvae of Chrysoperla carnea (127.33±1.45) was noted under T7: 310C. Maximum mean larval period of Chrysoperla carnea (18.66±0.88 days) was noted under T1: 190C and minimum mean larval period of Chrysoperla carnea (10.00±1.15 days) was noted under T7: 310C. Maximum mean number of Chrysoperla carnea pupa (72.00±1.52) was noted under T6: 290C and minimum mean number of Chrysoperla carnea pupa (49.00±2.08) was noted under T7: 310C. Maximum mean pupation timing of Chrysoperla carnea (11.00±1.15 days) was noted under T1: 190C and minimum mean pupation timing of Chrysoperla carnea (4.66±0.88) was noted under T7: 310C. Maximum mean fecundity of Chrysoperla carnea (253.67±8.57 days) was noted under T6: 290C and minimum mean fecundity of Chrysoperla carnea (120.67±2.60 days) was noted under T1: 190C. Maximum mean oviposition rate of Chrysoperla carnea (54.33±1.76 days) was noted under T1: 190C and minimum mean oviposition rate of Chrysoperla carnea (24.33±2.02 days) was noted under T7: 310C. Maximum mean survival of Chrysoperla carnea male (24.00±1.15 days) was noted under T1: 190C and minimum mean survival of Chrysoperla carnea male (10.00±1.15 days) was noted under T7: 310C. Maximum mean survival of Chrysoperla carnea female (63.33±1.76 days) was noted under T1: 190C and minimum mean survival of Chrysoperla carnea female (38.33±3.75 days) was noted under T7: 310C.
