Embodiment 1

[0024] Hang the lure at 1 to 2 cm above the middle of the upper edge of the white sticky insect plate, which constitutes the trapping and killing device for the groin groin beetle. Hang the trapping device on the outer edge of the side branches of the Camellia oleifera tree with a height of about 2.0m. The height is about 1.5m, which is just equal to the crown width. A total of 5 booby traps are installed, and another blank booby trap without lure core is installed; the distance between each booby trap is about 40m. The data is counted every 5 days, and the 20-day total amount of the groin-groined crocodile beetle is counted. The trapping results are shown in Table 1.

Embodiment 2

[0026] The difference with embodiment 1 is that the place where the trapping and killing device of the groin groin and the leaf beetle consisting of the lure core and the white sticky insect board is set is different, and in embodiment 2 it is suspended on the lower side branches of the camellia tree canopy with a tree height of about 3.0m The outer edge is about 1.5m in height, and the others are the same. The trapping results are shown in Table 2.

[0027] (2) Yellow sticky board experiment group

Embodiment 3

[0029] The difference from Example 1 is that the color of the sticky insect board is different. In the embodiment 3, the trapping and killing device of the groin crocodile beetle composed of a yellow sticky insect board and a lure core is adopted. Similarly, the trapping device is suspended at a tree height of about The outer edge of the side branches of Camellia oleifera is 2.0m. The height of the sticky insect board is about 1.5m, just equal to the crown width. It is advisable to set the direction of the yellow sticky insect board to avoid the shade of leaves. The trapping results are shown in Table 3.

Abstract

The invention discloses a Colaspoides opaca Jacoby attractant, a method for making an attractant core and a trapping and killing device. The attractant is composed of linalool, geraniol, methyl salicylate, cis-3-hexene-l-ol and nonanal. The attractant is dissolved in dichloromethane and the solution is added on a latex plug drop by drop so that an attractant core is prepared after natural volatilization. Through combination of the attractant core and a sticky coloured card, the trapping and killing device using the Colaspoides opaca Jacoby attractant is formed. The attractant is prepared fromplant volatiles and has strong attraction to the Colaspoides opaca Jacoby.

Description

technical field [0001] The present invention relates to the deworming technology in commercial forests, in particular to an attractant, a method for making a lure core and a trapping and killing device. Background technique [0002] Colaspoides opaca Jacoby belongs to the genus Colaspoides opaca Jacoby of the family Eumolpidae in the order Coleoptera, and is also called camellia oleifera. C. chinensis is widely distributed in Yunnan, Guangdong, Guangxi, Taiwan, Hainan, Fujian, Guizhou, Sichuan and other places in China. It feeds on Camellia oleifera, Camellia sinensis, Vernicia fordii, Various plants such as Bauhinia purpurea and Schima sp. The insects gather on the twigs and young leaves of camellia oleifera and feed, making the leaves appear notched or window spots, and in severe cases, the whole leaf can be eaten. When the insect population density is too high, it will reduce the photosynthesis of the leaves, resulting in poor growth of the tree; the damage to the branc...
