Abstract

Biology of polyphagous predator, green lacewing (Chrysoperla zastrowi sillemi (Esben-Petersen)) on Corcyra cephalonica eggs along with its predation potential on C. cephalonica and A. gossypii was studied under laboratory conditions. Biological studies indicate that the incubation period, total larval period, pupal period, adult male and female period of C. zastrowi sillemi averaged at 3.00±0.06, 8.53±0.54, 8.03±0.26, 27.75±1.17 and 33.25±1.45 days, respectively. The average pre-oviposition, oviposition and post- oviposition period was reported as 4.70±0.76, 25.30±1.18 and 3.25±1.02 days respectively. All the three larval stages of C. zastrowi sillemi are voracious predator of insect eggs and soft bodies insects. A green lacewing grub on an average consumed 276.40±11.88 eggs of C. cephalonica and 349.00±21.19 nymphs and 179.80±9.32 adults of cotton aphids during its developmental period. This study explores the possibilities of ease of rearing of chrysopids for field release as well as its effectiveness in pest control

Conclusion

The biological studies of Chrysoperla species are crucial for advancing sustainable agricultural practices. Understanding their lifecycle, feeding habits, and functional responses aids in optimizing their use as biological control agents. These natural predators offer an eco-friendly alternative to chemical pesticides, effectively managing pest populations while minimizing environmental impact and preserving beneficial insects. Promoting such biological control strategies is essential for achieving long-term agricultural sustainability and food security
