[0003] Cydia trasias Meyrick is one of the main pests of Chinese pagoda tree. In the north, there are usually two generations per year. It is slightly damaged by larvae that bore into new ones in one year. The newly hatched larvae mostly enter from the base of the pinnate compound petiole. Hazards in the branches, causing the compound leaves or twigs to dry or break, seriously affecting the growth and yield of Sophora japonica

Embodiment 1

[0038] Embodiment 1, the investigation of the regularity of the occurrence of the national Huaihuai small tortrix

[0039] Use the sex attractant of Chinese pagoda moth to trap. From March 27, 2017, the trapping test was carried out at the Pinghuai rice base in Xishan, Beibei. Place two lures diagonally, and the traps are hung on the branches in the middle of the tree. The distance between the two traps is 30m. The number of male adults on the sticky board of the traps is counted every 7 days (postpone in case of rain), 4 weeks Replace the lure once; combined with field observation, dissect the branches with insect infestation, observe the occurrence and development degree of larvae, and infer the regularity of its occurrence.

[0040] In 2017, six consecutive months of trapping experiments and the observation of larvae in the branches showed that the larvae had two generations in one year in Chongqing Jinhuai Base, and there was generation overlap. In late October, mature la...

Embodiment 2

[0041] Embodiment 2, adopting the sex attractant of Chinese pagoda japonica torch to trap

[0042] From March 27, 2017, the trapping test was carried out at Huaimi base in Xishanping, Beibei. The trap was in the shape of a triangle (purchased from Beijing Zhongjie Sifang Biotechnology Co., Ltd.), with a lure hanging in the middle, and sticky insects pasted on both sides and the base board, the trap is hung in the middle of the tree, the distance between the two traps is 30m, the number of male adults on the sticky board of the trap is counted every 7 days (postponed in case of rain), and the lure core is replaced once every 4 weeks ( figure 2 ). Combining with field observation, dissect the branches with insect infestation, observe the occurrence and development degree of larvae, and infer the regularity of its occurrence.

[0043] Statistical results: From March 27th, the number of male adults of the petiole moth was counted, and from the beginning of April, the adults in t...

Embodiment 3

[0046] Embodiment 3, medicament control

[0047] Used medicament purchase factory is as follows: 25 grams / liter deltamethrin (Bayer Crop Science (China) Co., Ltd.); 10% beta-cypermethrin (Shanghai Yuelian Chemical Co., Ltd.); Hualing Pesticide Co., Ltd.); 0.5% matrine water agent (Beijing Sanpu Baicao Green Plant Preparation Co., Ltd.); 0.3% azadirachtin EC (Chengdu Green Gold Biotechnology Co., Ltd.); 1.5% natural pyrethrin aqueous emulsion ( Inner Mongolia Qingyuanbao Biotechnology Co., Ltd.); 22% Sulfoxaflor SC (Dow AgroSciences); 70% Imidacloprid Water Dispersible Granules (Bayer Crop Science (China) Co., Ltd.); 0.4% Fructus Cnidii Vegetarian EC (Wuhan Tianhui Biological Engineering Co., Ltd.); 16000IU / mg Bacillus thuringiensis wettable powder (Wuhan Tianhui Biological Engineering Co., Ltd.); 7.5% rotenone EC (Inner Mongolia Qingyuanbao Biotechnology Co., Ltd.); 5% methylamino Vermectin benzoate (Yinnong Technology Co., Ltd.).

Abstract

The invention discloses a preventing and treating method for eydia trasias meyrich. The method comprises the following steps: using an eydia trasias meyrich sex attractant to lure male adults at the end of April and in the beginning of May; and then preventing and treating eydia trasias meyrich with an agent from mid-to-late of May to the first ten-day period of June and from the last ten-day of June to the last ten-day of July, separately. The agent is prepared by compounding at least two of rotenone, agritol, imidacloprid, beta-cypermethrin, emamectin benzoate, sophocarpidine, azadirachtin,fluorodinitrile, cnidium lactone and deltamethrin. The method is good in preventing and treating effect to eydia trasias meyrich, can improve the output of sophora flower buds and has important meaning in preventing and treating eydia trasias meyrich.

Description

technical field [0001] The invention relates to a control method, in particular to a control method of the Chinese japonica moth. Background technique [0002] Sophora japonica Linn. is a perennial deciduous tree belonging to the Fabaceae Papilionaceae. It is one of the excellent street tree species. Its unopened flower buds are Sophora japonica Linn., which has the functions of stopping bleeding and cooling blood, clearing the liver and improving eyesight.
