1. Installation of trapping time: According to the monitoring situation of Plutella xylostella, the first peak period of adult occurrence of Plutella xylostella is the ideal trap time.
2. The main techniques for installing trapping basins: Suitable for the installation of harvesting pots (cabbage, cauliflower, cabbage, vegetables, kale, radish and other cruciferous crops) Place 2 traps per acre, basin edge 5 cm from the vegetables, with A steel wire is used to hold the lure and the two sides are fixed on the edge of the basin. Fill the basin with water, and leave the lure to 1 cm. Do not dip into the water. A small amount of washing powder can be added to the pot to increase the trapping effect.
3. Note:
(1) Add water to the trap basin in time. The drop in water surface affects the trapping effect of the trap.
(2) Change the lure in time. The lures are changed every 30 to 40 days to ensure the trapping effect; the use of the lure will be shortened in the continued high temperature and high humidity weather.
(3) Adjust the height of the trapping basin in due course. The distance between the lure and the top of the crop is 10 to 20 cm, that is, the trapping basin should be kept above the crop, and the pelvic floor should not touch the crop. (Fields can use cement bricks, etc. to trap pots).
(4) Reasonably place trapping pots and adjust the location of trapping points in time. When installing the trapping pots in the field, they should be laid out rationally, arranged in a checkerboard pattern; avoiding non-cruciferous crops such as garlic and celery that have repellent effects on Plutella xylostella adults; warnings against Plutella xylostella in order to avoid prolonged fixation of the traps in the same position In order to influence the effect of booby trapping and other actions such as calling for help, you need to move the trapping point once a month in a certain direction.
