بررسی تأثیر کائولین روی فراسنجه‌های جدول زندگی کنه تارتن انجیر Eotetranychus hirsti در شرایط آزمایشگاه

The highest amount of fig production as one of the export products in Iran and Fars Province related to Estahban County. Since fig spider mite, Eotetranychus hirsti Pritchard & Baker (Acari: Tetranychidae), is one of the most important pests of fig in Estahban County, it is important to choose a suitable pesticide that is no harmful to human and nature. Using demographic toxicology method, the life table parameters of the fig spider mite were evaluated using Kaolin 3%. Experiment was carried out with two treatments, control and Kaolin treated with dipping leaf disk method in 70 replications. In this experiment, one day old eggs were used as the primary population and until the death of the last adult mite, they were kept in germinator at 28 ± 2°C, relative humidity 55 ± 5% and a photoperiod of 16:8 h (L:d). Survival rate data at each growth stage and the number of females produced per day were recorded. In this research an age-stage specific life table was used. Data were analyzed using the Age-Stage, Tow-sex life table analysis MSchart software version 2017. The results showed that the Kaolin treatment with repellant effect significantly reduced the longevity of adult mites, gross reproduction rate (GRR), net reproduction rate (R0), the intrinsic rate of increase (rm), the finite rate of increase (λ), the mean generation time (T), the oviposition period and the number of eggs per female. Significant effect on the biological parameters was also detected during the different developmental stages of fig spider mite.
