چکیده مقاله:
The generalist predatory mite, Amblyseius swirskii Athias-Henriot (Acari: Phytoseiidae) is a widely used natural enemy of phytophagous pests in greenhouses. Among new and more environmentally friendly control tools, botanical pesticides represent a valuable alternative to synthetic ones within integrated pest management strategies. The effect of sublethal concentrations of a botanical pesticide derived from wild pistachio, Pistacia atlantica Desf. var. Kurdica (Anacardiaceae) and its nanocapsulated essential oil at LC10, LC20, and LC30 were investigated on biological parameters of A. swiriskii under laboratory condition at 25 ± 1°C, 60 ± 5% RH and 16L:8D h photoperiod. The data were analyzed based on a two-sex life table method. Our results showed that sublethal concentrations of this pesticide had no significant difference on the life table parameters of the treated mites in comparison with the control. At control, LC10, LC20 and LC30, the gross reproductive rate (GRR) was 3.47, 2.93, 2.10 and 2.96 eggs/individual, respectively. The maximum and minimum values for the net reproductive rate (R0) were recorded to be 3.44 (in control) and 1.95 (in LC20) eggs/individual for the treated mites. At above-mentioned four concentrations, the intrinsic rate of increase (r) was 0.102, 0.082, 0.057 and 0.089 day–1, respectively. The results of this study indicated that sublethal concentrations of this pesticide had no adverse impact on A. swiriskii performance and the use of this biopesticide can be recommended as a component of integrated pest management programs.
