اثرات سمیت حاد و زیرکشنده کنه‌کش اگری‌فلکس روی کنه شکارگر Amblyseius swirskii (Acari:Phytoseiidae)

The Two-Spotted Spider Mite (TSSM), Tetranychus urticae Koch (Acari: Tetranychidae), is an important pest in greenhouse and farms, also may be infested at high humid condition. Amblyseius swirskii Athias-Henriot (Acari: Phytoseiidae) as a part of predatory communities in greenhouses all over the world. In this study, we determined the sublethal effects of Agrifelex on the life history and demographic parameters of A. swirskii temperatures: 25 °C, 60 % relative humidity and a photoperiod of 16: 8 h (L: D) with the density of LC5 and LC8 . The Two-spotted spider mite, T. urticae, was used as prey. In conclusion, results showed that The net reproductive rate (R0) decreased with increasing density from 1.64 offspring/individual to 1.78 offspring/individual . The values of the intrinsic rate of increase (rm) and finite rate of increase (λ) were obtained to be highest at 25°C (0.157 day –1 and 1.170 day–1, respectively). The mean generation time (T) decreased with increasing density from 9.32 days at LC5 to 8.59 days at LC8, respectively. Based on the results of the population characteristics, Agriflex is not a suitable poison for this A. swirskii. Considering that this poison has side effects in most of the life stages of the A. swirskii tick, also based on the results obtained from the sublethal effects of the toxins on the demographic parameters of the A. swirskii tick, the use of sublethal doses of toxins during The use of A. swirskii mite in integrated pest management programs can not be a suitable choice for Tartan mite control.
