The side effects of two insecticide, flupyradifurone and hexaflumuron on the biological parameters of the Chrysoperla carnea (Stephens) feeding on Agonoscena pistaciae Burckhardt and Lauterer

The common green lacewing, Chrysoperla carnea (Stephens) (Neu.: Chrysopidae) is a cosmopolitan polyphagous
The common green lacewing, Chrysoperla carnea is a cosmopolitan polyphagous predator, attacking various pests, including eggs and nymphs of the common pistachio psylla, Agonoscena pistaciae. In this study, side effects of two insecticides, flupyradifurone and hexaflumuron, were investigated on the biological parameters of the common green lacewing, C. carnea population by feeding method in which pistachio psylla nymphs immersed in the insecticide solution. Results has shown that there were significant differences among treatments for intrinsic rate of natural increase (r), the finite rate of increase (λ) and net reproductive rates (R0) parameters. The results of statistical analysis showed that intrinsic rate of natural increase (r) and the finite rate of increase (λ) in control (1.1411±0.0076, 0.1320±0.0066), flupyradifurone (1.1184±0.0073, 0.1119±0.0006) and hexaflumoron (0.08239±0.0094, 1.0858±0.0102) d-1 were placed in three separate groups. Also, the net reproduction rate in the two treatments of control (357.63±0.11) and flupyradifurone (247.26±43.03) (offspring) were in the same statistical group which showed a statistical difference with hexaflumoron (38.04±12.37).  According to these results, flupyradifurone, in contrast to hexaflumuron, did not have a significant negative effect on r, λ and R0 of C. carnea.
