Second, the investigation and monitoring of brownback flat rat damage The main purpose is to investigate the density of memory rodents, predict what will happen in the winter, and decide whether or not to take preventive measures. (i) Survey of existing rat densities 1, time requirements: in the fall of the rat peak activity in September. 2. Survey method: The survey was conducted using the clip method (ie, the clip method). Clipping method is a method of capturing one day and night with a clip, and the clip date is a unit for calculating the number. (1) Determine the number of clips: Arrange the number of clips according to the size of the rodent damage within the small class. To increase the accuracy, at least 50, refer to (Table 7-8). Table 7-8 Table of Determining Days for Murder Investigation Small rats in the class Occurrence area (mu) 200 or less 200―500 500―1000 1000 or more Clipping days (a) 50 100 150 200 or more 125m long Survey Line (Article) 2 4 6 8 Representative plot area 7.50 15.00 22.50 30.00 (2) Cloth clips: The clip time can be selected in the afternoon, the clip type should be the same, and the bait used for each clip should be the same (using wheat or fried pine nuts). In the rodent sub-class, select a representative area to set up survey lines, 1 to n lines, straight line clips on the line, clip distance 5m, row spacing 20 m, 25 clips per line, line length 125 m, representative The plot area is 3.75 mu. (3) Investigation: After each visit, the animals were observed at 8 to 10 o'clock the next day and at 18 to 19 o'clock the next day. When they were found to have caught rats, they should be removed immediately. After the rat was identified as a brownbacked rat, it was recorded as a rat. The investigation of wild debts (see Table 3-2) and the replacement of new bait should be carried out. Replacement of the local bait should be carried out. The survey should pay attention to two points: First, if it is judged that the bait is lost and the folder is clamped by the brownback mouse (The mouse has hairy hairs or new mouse droppings, etc.), which should be included in the number of captures. Second, in case of severe winds, heavy rain, and Other abnormal weather, the results of the day’s rodents are not included in normal statistics. The number of captures is for reference only. (4) Statistical calculation of the capture rate: Each clip is used for 1 day and night, and the total number of traps should be counted after the clip date to be investigated. Calculate the capture rate according to the formula. Sum of the number of acquisitions for each survey line Small rodent trap rate %= ─────────────×100 25× Survey Lines × Capture Days and Nights (5) Determine the existing rat density: The mouse density is divided into high, medium and low grades, etc., which can be determined according to Table 7-10 according to the capture rate. (B) Predicting hazards in winter 1, the mouse density: the results of the autumn survey. 2, the degree of harm: According to the mouse density, refer to the table (7-11) to determine. 3. Damaged plant rate: Determined according to Table (7-11). 4. Occurrence area: Starting from the light statistics starting point, it can be determined with reference to the original small class area. (iii) Determine the area to be prevented The area predicted to be moderately above is the area to be protected.
