[Abstract]:In order to determine the effect of herbicides on the activity of Pardosa astrigera, the toxicity of three conventional herbicides, ethoxyflurane, carboxyflurane and paraquat, was determined by membrane method. The effect of herbicide on the activity of herbicide was studied by field test. The results showed that the LC10 of carboxyflurane was 6.75g / L and the LC10 of ethoxyflurane was 1.09 g 路L ~ (-1) 路L ~ (-1). The order of toxicity of three herbicides was ethoxyflurane, paraquat. The total walking distance and the average walking speed of male spiders treated with ethoxyflurane were significantly lower than that of the recommended concentration treatment (0.07 g / L). The total distance of female spiders after treatment with 6.75 g / L ethoxyflurane was significantly lower than that of the other concentration treatments. The maximum walking speed of male spider was significantly lower than that of 0.08 g / L treatment, but there was no significant difference between the two herbicide concentration treatments and the control. The total walking distance of male spider was 80.00 g / L paraquat treatment. The maximum walking speed and average walking speed of female spiders were significantly lower than that of the control, which were 248.48 cm / L 12.03 cm/s and 0.83 cm / s / L paraquat treatment, respectively, and the maximum walking speed of female spiders decreased significantly after treatment with paraquat at 80.00 g / L, and the number of walking areas of male spiders decreased significantly after treatment of 5.81 g / L ethoxyflurane, respectively. Compared with the control group, the number of walking areas of female spiders decreased by 4.57, and increased by 2.20 .20.83 g / L ethoxyflurane, and the male spiders stayed in the central region for the shortest time. It was 0.48 s, the proportion of the total time was only 0.16% 5.81 g / L ethoxyflurane treatment, the female spider stayed in the central area the longest, 15.94 s, the proportion of the total time was 5.31. The results showed that the high concentration herbicide had a significant effect on the activity behavior of the spider, but the recommended concentration had no significant effect on the activity of the spider, indicating that the three herbicides were relatively safe for the spider at the recommended dose.
