[0005]The booby ball can be used in combination with the lure core to improve the use effect of the booby ball. Jiang Yingchun and others first disclosed the invention of combining the lure core and the booby ball to trap citrus fruit together. Fly adults, but because the effect of the lure is not good enough, it has not been applied and promoted. A kind of citrus fruit fly adult active ball disclosed by Mo Bocheng and others is to combine the popularized and applied trap ball with limonene invented by Zhang Hongyu and invented by Zhou Qiong. combined with undecyl alcohol, used to control adults of Bactrocera citrus, but our research group verified that the control effect of the active ball was not significantly different from that of the single-use trap ball

Embodiment example 1

[0035] In order to explore the influence of plant odors on the adult behavior of Bacterophae citrus in the orangery system, citrus leaves, flowers, and fruits were used as odor sources, and Gardenia, a common plant in orchards, was selected. In order to unify the types of odor sources, all plants were selected. essential oil, and adjust the concentration of the essential oil to 10% with liquid paraffin, and use a Y-type olfactometer to conduct olfactory responses to adults of Bactrocera citrus. In order to broaden the range of selection, we further selected plant types that have been reported to have repellent effects on insects. A total of orange essential oil, orange leaf essential oil, neroli essential oil, gardenia essential oil, lemon eucalyptus essential oil, peppermint essential oil, wormwood essential oil, Grapefruit essential oil, limonene, linalool, myrcene and other materials, the results obtained are shown in Table 1, and lemon eucalyptus essential oil with better o...

Embodiment example 2

[0046] On May 30, 2018, a piece of orange orchard in Shaoyang County with a serious occurrence of Bactrocera citrus was selected, with an area of ​​20 mu, and the variety was Newhall navel orange. 200 trees were randomly selected, and 100 trees were randomly selected to hang new trapping balls , Another 100 trees were hung with booby traps, and each tree was hung with one booby booby in the open space in the middle and upper part of the citrus tree. The results were found after 2 weeks, and the average number of male adults of Bactrocera citrus on each new booby trap was 10.0 The average number of heads and female adults was 8.6, while the average number of male adults and female adults of Bactrocera citrus on the corresponding trapping balls was 7.1, and the average number of female adults was 4.8. The trapping effect of the new trapping ball increased by 56.3%.

Embodiment example 3

[0048] On June 2, 2018, in Luxi County, an orange orchard with a serious occurrence of Bactrocera citrus was selected, with an area of ​​100 mu. Each plot adopts trapping balls, and each plot hangs 12 new trapping balls or trapping balls in the open space in the middle and upper part of the citrus tree. After 2 weeks, the results are checked, and the average number of male adults of Bactrocera citrus on each new trapping ball 9.6, the average number of female adults is 7.9, while the average number of male adults and female adults of Bactrocera citrus on the corresponding trapping ball is 6.5, and the average number of female adults is 5.2. The trapping effect of the new trapping ball has increased by 45.6%.

Abstract

The invention discloses a method for trapping and killing adult tetradacus citri. The method includes: putting a trapping and killing ball on a citrus tree, and putting a trapping core in the trappingball or around the same, wherein a yellow area and a green area are distributed on the outer surface of the trapping ball and distributed on two sides of the ball respectively, and a yellow-green gradually-changing area is arranged between the yellow area and the green area. By the method, yellow and green trapping and killing balls can be combined with the trapping core, trapping and killing effect is improved remarkably, and chemical prevention and control can be reduced or omitted; the method is pollution-free, meets environment-friendly prevention and control rules of plant diseases and insect pests and is simple and convenient in operation.

Description

technical field [0001] The invention relates to a method for trapping and killing adults of Bactrocera citrus, in particular to a method for trapping and killing adults of Bactrocera citrus by combining plant information materials and glue trapping balls. Background technique [0002] Bactrocera (Tetradacus) minax (Enderlein)), belonging to the order Diptera, Tetradacus, and the genus Bactrocera, mainly feeds on the pulp of citrus fruits with its larvae, causing the fruits to yellow before they are ripe and fall off early , Lose the edible value, cause all the fruits to fall off in severe cases, seriously affect the fruit yield and quality. The danger of Bactrocera citrus is great. After the adults lay eggs and enter the fruit, there is no remedial measure. The most effective control method is adult trapping technology, which mainly includes trapping with lures and physical trapping. [0003] At present, the most commonly used traps are the food traps that use the nutrition...
