Embodiment 1

[0022] From July 4th to 14th, 2019, the trapping effect test of synergistic agents combined with tea-winged bug aggregation pheromone lures was carried out in Dongdong Village, Langfang City, Hebei Province.

[0023] Components of the synergist: the purity of oxidized linalool, linalool, benzaldehyde and ethyl lactate is above 99%.

[0024] Benzaldehyde, linalool, linalool oxide, and ethyl lactate were dissolved in n-hexane at concentrations of 5 mg / ml, 10 mg / ml, and 20 mg / ml, respectively, and 200 microliters were added dropwise to the solution washed with n-hexane. After the n-hexane volatilized, 200 microliters of dichloromethane was dripped twice on the septum of the rubber stopper, and after the dichloromethane volatilized, the synergist lure was prepared. Put the prepared single-component synergist lure into aluminum foil, seal it, and store it at -20°C.

[0025] Mix the components according to the composition in Table 1 and dissolve them in n-hexane to make a n-hexane ...

Embodiment 2

[0034] The lure synergist of the tea wing bug in this embodiment comprises the following components in parts by weight: 5 parts of linalool oxide, 2 parts of linalool, 2 parts of benzaldehyde, and 2 parts of ethyl lactate. Mix according to the composition of tea wing bug attractant synergist and make the n-hexane solution of multi-component synergist, solution concentration is 10 mg / ml, drip 200 microliters on the septum of the rubber stopper that cleans with n-hexane, wait After the n-hexane volatilized, 200 microliters of dichloromethane was dripped twice on the septum of the rubber stopper, and the synergist lure was prepared after the dichloromethane volatilized. Put the prepared multi-component synergist lure into aluminum foil, seal it, and store it at -20°C.

[0035] This synergist lure was carried out in the field trapping test according to the method of Example 1, and it was found that after using the synergist lure containing the tea winged bug attractant of the pres...

Embodiment 3

[0037] The lure synergist of the tea wing bug in this embodiment comprises the following components in parts by weight: 8 parts of linalool oxide, 5 parts of linalool, 1.5 parts of benzaldehyde, and 1 part of ethyl lactate. Mix according to the composition of tea wing bug attractant synergist and make the n-hexane solution of multi-component synergist, solution concentration is 10 mg / ml, drip 200 microliters on the septum of the rubber stopper that cleans with n-hexane, wait After the n-hexane volatilized, 200 microliters of dichloromethane was dripped twice on the septum of the rubber stopper, and the synergist lure was prepared after the dichloromethane volatilized. Put the prepared multi-component synergist lure into aluminum foil, seal it, and store it at -20°C.

[0038] This synergist lure was carried out in the field trapping test according to the method of Example 1, and it was found that after using the lure of the synergist containing the tea-winged stink bug attracta...

Abstract

The invention discloses an attractant composition using an attractant synergist of the tea-winged stinkbug, its application and a lure core. The tea stink bug attractant composition comprises the tea wing bug aggregation pheromone and a synergist, and the weight ratio of the tea wing bug aggregation pheromone to the synergist is 0.25-4:1. The synergist is selected from three kinds of benzaldehyde, linalool and linalool oxide in different proportions. The attractant composition provided by the invention can be made into a lure core to be used in conjunction with the existing aggregation pheromone of the stinkbug. The invention provides a lure core containing the components of the tea-winged bug attractant composition, which is used for preventing and detecting the occurrence of the tea-winged bug. The invention solves the disadvantages of high cost and difficult popularization of imported and domestic tea wing bug aggregation pheromone lures in the prior art, and has low cost, flexible use and higher trapping efficiency.

Description

technical field [0001] The invention relates to the technical field of pest monitoring and trapping, in particular to an attractant composition using a synergistic agent for a tea winged bug attractant, an application thereof and a lure core. Background technique [0002] The tea-winged bug (Halyomorpha halys) is a polyphagous pest originating in East Asia. It has become an important worldwide pest because of its wide range of host plants and has invaded many countries in North America, Europe, South America and Africa. Agricultural and forestry pests. The feeding method of adults and nymphs of the stinkbug is mainly by piercing the sucking mouthparts into the plants and fruits to absorb nutrients. The sucked fruits will have insect spots and cause lignification inside the fruits, becoming The malformed fruit is inedible, seriously reduces the fruit grade and thus greatly reduces the economic benefits of the fruit, and the young shoots of the plant after being sucked cannot...
