بررسی اثرات غلظت زیرکشنده کنه‌کش اگریمک‌گلد روی پارامترهای دموگرافی‌کنه شکارگر Amblyseius Swirskii (Acari: Phytoseiidae)

Phytoseiid mites are the most important natural enemies of pest mites to be considered in integrated pest management. Amblyseius swirskii (Athias-Henriot) (Acari: Phytoseiidae) is a predatory mite widely distributed and have been used to the control of spider mites in the field and greenhouse horticultural crops. Life tables give the most comprehensive description of the development, survival, stage differentiation, reproduction and consequently population growth of a population. The experiments were performed at 16: 8 hours (dark: light) and relative humidity of 65- 75%. The objective of this research was to evaluate the life table parameters of A. swirskii, at Sub-lethal concentration of Agrimic Gold poison is in laboratory conditions. The tested poison caused a significant decrease in fertility. The net reproduction rate (R0) decreased from 8.828 to 5.971 with increasing concentration. The values of the intrinsic rate of increase (rm) also decreased significantly with the increase in concentration from 0.205 to 0.177 respectively. finite rate of increase (λ) In the concentrations (LC10 and LC20), it decreased by 1.227 and 1.194 days, respectively, which did not have a significant difference. The mean generation time (T)With the increase in concentration, it decreased from 10.60 to 10.05 days, but there is no significant difference. Based on the results obtained from the Sublethal concentration of Agrimic Gold poison on the demographic parameters of Swiriskii, the use of sublethal doses of poisons in the integrated pest management program immediately after spraying this acaricide is not recommended.
