preparation example Construction

[0042] The present invention also provides a method for preparing the lure described in the above scheme, comprising the following steps:

[0043] The attractant is dissolved in a solvent to obtain an attractant solution, and the carrier is used to adsorb the attractant solution to obtain the lure core of the firefly beetle.

[0044] The present invention has no special requirements on the preparation method of the attractant solution, as long as hexanal, cis-3-hexenal and cis-3-hexenol are dissolved in a solvent according to the ratio described in the above scheme.

[0045] The present invention has no special requirements on the adsorption method, and the carrier can naturally adsorb the attractant solution. In a specific embodiment of the present invention, it is preferable to put 10 blank rubber tips into a conical flask as a group, and add 250 μL of attractant solution to the conical flask, and stir with a glass rod while dripping to make the rubber tip evenly adsorbed. ...

Embodiment 1

[0048] (1) GC-EAD analysis of volatiles in the host of Phyllostachys tarsus

[0049] The headspace adsorption method was used to extract the volatiles from the aboveground part of the host plant, Glycyrrhiza uralensis, and to detect the GC-EAD reaction of the antennae of the beetle, and the results were as follows figure 1 shown, according to figure 1 It can be seen that the antennae have electrophysiological responses to 9 separated components, which appeared at 7.17min, 8.20min, 9.97min, 12.15min, 13.20min, 14.00min, 14.35min, 15.53min and 15.98min, and appeared in multiple can be repeated on each antennae.

[0050](2) GC-MS identification of licorice tarsus volatiles

[0051] GC-MS analysis of the volatile extracts from the aerial parts of the host Glycyrrhiza uralensis showed the following results: figure 2 as shown, figure 2 It shows that 9 kinds of separated components were detected successively at 6.73min, 8.44min, 10.95min, 14.91min, 16.74min, 17.81min, 18.57min,...

Embodiment 2

[0063] According to the mass ratio of hexanal, cis-3-hexenal and cis-3-hexenol as the ratio of 10.80:18.78:70.42, the attractant was prepared, and the attractant was dissolved in dichloromethane to obtain a concentration of 100 μg / μL of lure, take the blank rubber-tipped lure out of the package, put 10 pieces into 100ml conical flasks, add 250 μL of lure to each conical flask, and stir with a glass rod while dripping to make the absorption even. Lure cores loaded with 2500ug of active ingredients are sealed and packaged with 10 pieces / bag of aluminum film, and stored at 4°C.

Abstract

The invention relates to the technical field of insect luring, and provides a schizophrassica juncea attractant, a luring core and a preparation method of the luring core. The attractant provided by the invention is prepared from the following components: hexanal, cis-3-hexenal and cis-3-hexenol; the mass ratio of the hexanal to the cis-3-hexenal to the cis-3-hexenol is (10 to 15) to (15 to 20) to (65 to 75). The attractant provided by the invention is specially prepared for the olfactory system of the schizophrassica juncea, has the characteristics of specific target, good attraction effect and high efficiency, is prepared into an attraction core, is used for monitoring and preventing adults of the schizophrassica juncea, and has the characteristics of environment friendliness, investment saving and simplicity in operation.

Description

technical field [0001] The invention relates to the technical field of insect lures, in particular to an attractant for the firefly beetle, a lure core and a preparation method thereof. Background technique [0002] Diorhdba tarsalis Wise., also known as licorice firefly beetle, only eats licorice, and eats licorice leaves with adults and larvae. It can eat up the mesophyll of licorice in 3-5 days, leaving only the reticulate stems stems and veins, causing a large loss of licorice yield every year. At present, the prevention and control of the firefly beetle still relies on chemical pesticides, resulting in "3R" problems such as pesticide residues in medicinal materials and excessive levels of toxic heavy metals, seriously affecting the competitiveness and sustainable development of the licorice planting industry. Control measures are imperative. [0003] Lure control technology is one of the feasible ways for the green control of firefly beetle. Herbivorous insects eat by...
