2018 citrus fruit fly control technology program

I. Key prevention and control areas

The key citrus production areas of Hunan, Hubei, Guizhou, Chongqing, Sichuan, Shaanxi and other provinces (municipalities) and other citrus fruit fly re-emergence areas are the key areas for prevention and control.

Second, the main technical measures

1. Adults return to the park to monitor the use of hanging bottles and other methods to monitor the beginning of adult return to the park, accurately determine the prevention and treatment period, do a good job of classification guidance, provide a basis for large-scale prevention and control.

2. Adult trapping According to the monitoring situation, in the beginning and end of the emergence of the citrus fruit fly, the adult is usually trapped during the middle to late May to late July.

(1) Hanging bottle (trap) trapping for orchards with a worm rate of 3% or less, it is possible to use a food attractant such as a sex attractant and a sweet and sour liquid to hang a bottle (trap) to trap the adult, 8 to 10 per acre. Change the attractant every 7 days. The glue can be sprayed on the outer wall of the trap to improve the trapping effect.

(2) Point spray to kill orchards for orchards with a rate of more than 3%, use protein poison bait spray, spray 10 points per acre, 0.5 square meters per point, or sweet and sour liquid spray one-third of citrus trees per acre, each The tree is sprayed with one third of the canopy. Spraying once every 7 days, the oranges are usually sprayed 3 to 5 times, and the citrus and oranges are sprayed 4 to 6 times.

(3) Hanging viscose ball traps to trap. 8~10 viscose ball traps per acre, each trap is about 10 meters apart.

3. Picking up the fruit and the insect fruit to pick up and treat the insect fruit has a greater effect on controlling the base of the pests in the next year.

(1) Picking up the fruit from mid-September to late November, regularly picking up the fruit in the garden, once every 2~3 days, once every day during the peak period, and removing the untreated eggs, once every 7 days. Hillside orchards dig shallow trenches under the slope to intercept the collection of insects. Waxing processing plants, scattered trading points and unmanaged orangegrass insects are collected and processed centrally.

(2) The fruit that is picked up and removed by the insects is placed in a plastic bag on the spot, and the pocket is tightly sealed and smothered. After 7~10 days of fruit decay, the rotten fruit is buried in the soil as a fertilizer, and the insect fruit processing bag can be reused. The collected insects can also be sent to the insect fruit treatment pond to soak and kill, or feed the fish and feed the pigs. (Agricultural Investment Report)
