preparation example Construction

[0045] The present invention also provides a preparation method of the above-mentioned attractant for tardigrade gnats, comprising:

[0046]Get volatile solvent, dilute allyl methyl disulfide and diallyl disulfide respectively, obtain allyl methyl disulfide dilution and diallyl disulfide dilution, allyl Methyl disulfide dilution and diallyl disulfide dilution are mixed until the mass ratio of allyl methyl disulfide to diallyl disulfide is 20:1-1:2 or 15: 1-2:3 or 10:1-1:1 to prepare the attractant.

[0047] Among them, the volatile solvent is methanol, dichloromethane, n-heptane, toluene, n-hexane, pentane, benzene, styrene, butyl toluene, vinyl toluene, trichloroethylene, carbon disulfide, tri-o-cresol phosphate One or more than two.

[0048] In a preferred embodiment, the volatile solvent is n-hexane.

[0049] In a preferred embodiment, the concentration of the allyl methyl disulfide dilution is 0.1-1.0 mg / μL, and the concentration of the diallyl disulfide dilution is 0.0...

Embodiment 1

[0060] The raising of embodiment 1 Chive tardigrade

[0061] The feeding conditions are temperature 25°C and relative humidity 70%±5. Select 80 to 100 male and female adults with normal development and active behavior, place them in a plastic box with air-permeable gauze, pair freely, mate and lay eggs on wet filter paper, and then transfer the filter paper to a petri dish (9 cm in diameter). After the larvae hatched, fresh pseudostems of chives were selected as food.

Embodiment 2

[0062] Embodiment 2 The main volatile matter of Chinese chives and the attractant of different ratios thereof to the attracting effect of Chinese chive maggot adults

[0063] Lure preparation:

[0064] Using n-hexane as solvent, allyl methyl disulfide (AMD) was formulated into a solution with a solution concentration of 0.5 mg / μL, and diallyl disulfide (DD) was formulated into a solution with a concentration of 0.5 mg / μL, respectively. μL and 0.05mg / μL solutions.

[0065] Add 100 μL of 0.5 mg / μL allyl methyl disulfide (AMD) and 0.05 mg / μL diallyl disulfide (DD) to the lure respectively to make the first AMD:DD=50:5 an attractant lure;

[0066] Add 100 μL of 0.5 mg / μL allyl methyl disulfide (AMD) and 0.5 mg / μL diallyl disulfide (DD) to the lure respectively to make the second phase of AMD:DD=50:50. attractant lure;

[0067] Add 100 μL of 0.5 mg / μL allyl methyl disulfide (AMD) to the lure to make the third attractant lure of AMD=50;

[0068] Add 100 μL of 0.05 mg / μL diallyl...

Abstract

The invention provides a Bradysia odoriphaga attractant and a preparation method and application thereof and relates to the technical field of biological attraction. The Bradysia odoriphaga attractant provided herein comprises allyl methyl disulfide and diallyl disulfide, has significant attracting effect for Bradysia odoriphaga, is nontoxic and harmless and causes no environmental pollution; the preparation method of the Bradysia odoriphaga attractant provided herein is simple to perform and low in cost; an attracting core provided herein comprises the attractant provided herein, is efficient in attracting adults of Bradysia odoriphaga, and is capable of monitoring, trapping or killing the adults of Bradysia odoriphaga, thereby decreasing population density and damage of Bradysia odoriphaga to Chinese chives.

Description

technical field [0001] The invention relates to the technical field of biological lures, in particular to an attractant for tardigrade mosquitoes, a preparation method and application thereof. Background technique [0002] Bradysiaodoriphaga Yang et Zhang, also known as chive maggot, belongs to Diptera (Diptera), Sciaridae (Sciaridae), genus Bradysiaodoriphaga, and is serious in Northeast, Northwest, North and East China. Occurrence and harm, and there are sporadic reports in Central China, South China and Southwest China. According to statistics, Chive tardigrade can harm more than 30 kinds of vegetables in 7 families including Liliaceae, Compositae, Chenopodiaceae, Cruciferae, Cucurbitaceae and Umbelliferae. Among them, leeks in the northern protected area suffered the most, followed by garlic, onions, melons and lettuce, which can also harm edible fungi. Chive tardigrades have strong reproductive ability and serious generation overlap. The larvae gather and eat the unde...
