Life table studies of green lacewing, Chrysoperla zastrowi sillemi (Esben-Petersen) (Neuroptera: Chrysopidae), on the cabbage aphid, Brevicoryne brassicae L.
Life tables are important tools to assess the reproductive performance of predators on their target preys. Studies were conducted at the Department of Entomology, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Himachal Pradesh, India during 2019-20 to construct life fertility tables of of green lacewing predator, Chrysoperla zastrowii sillemi (Esben-Petersen) on cabbage aphid, Brevicoryne brassicae L. Through stage specific life tables, it was revealed that the net reproductive rate (Ro), approximate generation time (Tc) and innate capacity of natural increase (rc) of C. zastrowi sillemi were 80.83 female eggs per female, 42.29 days and 0.103, respectively. The true intrinsic rate of increase (rm) on B. brassicae was found to be 0.1098.
