Lethal and sublethal effects of three insecticides on green lacewing, Chrysoperla carnea (Neuroptera: Chrysopidae) under laboratory conditions
Journal Title: Journal of Entomological Society of Iran - Year 2021, Vol 41, Issue 2
Abstract
Chrysoperla carnea Stephens (Neuroptera: Chrysopidae) is an important beneficial predator in agriculture, which is easily reared in laboratory. It is widely used in augmentative biological control programs. Research on sublethal effects, aims to reveal the negative and non-lethal impacts of insecticides on pests and provide practical information for forming effective pest control strategies. The lethal and sublethal effects of tebufenozide, clothianidin, and flupyradifurone on the common green lacewing, C. carnea were investigated in laboratory conditions at 25 ± 2°C, 60 ± 5% RH and a photoperiod of 16:8 h. (L:D). The results indicated the oviposition period in insects treated with flupyradifurone (26.62 days) was significantly different from the oviposition period in insects treated with clothianidin (21.90 days) and tebufenozide (21.62 days). Total fecundity in flupyradifurone treatment was significantly higher than the total fecundity in other treatments. The life table experiment of current study showed the values of r in control and the populations treated with LC30 of clothianidin, tebufenozide and flupyradifurone were 0.15, 0.17, 0.14, 0.15 day-1, respectively. The finite rate of increase (λ) was affected with different treatments; and the values varied from 1.19 to 1.16 day-1 for C. carnea adults treated with clothianidin and tebufenozide, respectively. The highest survival rate of C. carnea was observed in control (58 days). Based on the results, it seems flupyradifurone may have less harmful effects on total lifespan, fecundity rate and bio-characteristics of green lacewing population than clothianidin and tebufenozide.
