Embodiment 1

[0017] 1. Using the headspace dynamic adsorption method, Super Q is used as the adsorbent to absorb the volatiles of healthy tea shoots, rinsed with organic solvents, and identified by gas-mass spectrometry with standard samples figure 1 and many ingredients in Table 1. In Table 1, the content of trans-2-hexenal is less, and the content of 1-penten-3-ol, 2-penten-1-ol and trans-2-pentenal is less than that of trans-2-hexenal Less, the relative content of the four is all set as 1, and it can be calculated from Table 1 that the content of cis-3-hexen-1-ol is about 5 times that of trans-2-hexenal, and the content of cis-3-hexene acetic acid The ester content is about 25 times that of trans-2-hexenal, so these six semiotic substances are formulated into a mixture at a ratio of 1 : 1 : 1 : 1 : 5:25, which is called an attractant for adult black thorn whitefly.

[0026] Example 2 Differences in the Effects of Two Attractants for Adult Whitefly Blackthorn

[0027] 1. Materials and methods

[0028]In 2006, our research group was granted the authorization of a national invention patent, the title is "Trapping method for adult nymphs of green leafhoppers with false eyes and adults of black-thorn whitefly in tea garden", the patent number is "ZL200410018062.1", among which black-thorn whitefly The adult attractant is composed of cis-3-hexen-1-ol, trans-2-hexenal and linalool, and the optimal ratio of the three is 1 : 1 : 1; the size of the jasmine yellow sticky board used is 40 cm × 20 cm. The adult black thorn whitefly attractant of the present invention consists of trans-2-hexenal, 1-penten-3-alcohol, 2-penten-1-alcohol, trans-2-pentenal, cis-3-hexenal En-1-ol and cis-3-hexene acetate, the optimal ratio is 1: 1 : 1: 1 : 5: 25, and the size of the jasmine yellow sticky board used is 25 cm × 25 cm.

Embodiment 3

[0033] Example 3 Comparison of the attracting effect of two kinds of specifications of jasmine yellow sticky board

[0034] 1. Materials and methods

[0035] One type of jasmine yellow sticky board measures 40 cm × 20 cm, and the other kind of jasmine yellow sticky board measures 28.3 cm × 28.3 cm. They have the same area and the same color indicators such as brightness and chroma.

[0036] On May 25, 2012, a large piece of pollution-free tea garden was selected in Gushi Town, Songyang County, Zhejiang Province. 50 pieces of jasmine yellow sticky boards with a size of 40cm × 20 cm and 50 pieces of jasmine yellow sticky boards with a size of 28.3 cm × 28.3 cm were selected and mixed. Placed in the tea garden with a spacing of 8 m × 8 m. After 24 hours, investigate the number of blackthorn whitefly adults trapped on each board, and calculate the mean number and standard deviation of the average trapping of each board on the two color boards. On May 25, 2013 and May 25, 2014, a...

Abstract

The invention provides a blackthorn whitefly adult attractant, which is composed of tea tree kaimin trans-2-hexenal, 1-pentene-3-alcohol, 2-pentene-1-alcohol, trans-2-pentene Aldehyde, cis-3-hexene-1-ol and cis-3-hexene acetate in a ratio of 1:1:1:1:5:25. The present invention uses the main compound in the smell of green leaves of tea trees as a basic component to make an attractant for black thorn whitefly in tea gardens, which is loaded on a rubber head to make a lure core, and attached to a jasmine yellow sticky board to trap adult black thorn whitefly , and greatly reduce the population density of whitefly larvae of the next generation, so as to reduce the use of chemical pesticides, thereby reducing pesticide residues in tea. The method of the invention is beneficial to the environmental protection of the tea garden, the protection and effective utilization of the biological diversity of the tea garden, and the method is convenient, efficient and low in cost.

Description

technical field [0001] The invention belongs to the field of plant protection, and relates to a blackthorn whitefly adult attractant and its application in trapping blackthorn whitefly in tea gardens. Background technique [0002] my country's tea garden area accounts for slightly more than half of the world's tea garden area. black thorn whitefly Aleurocanthus spiniferus (Quaintance) is widely distributed in my country's tea areas, and it seriously harms tea trees, citrus and palms, and also harms a variety of economic trees and ornamental plants. In the early 1960s, early 1970s, early 1980s, and late 1980s to early 1990s, it broke out intermittently in the middle and lower reaches of the Yangtze River in my country, South China and Hainan.
