Embodiment 1

[0061] Embodiment one: the preparation of sugarcane bar borer sex attractant

[0062] 0. Preparation of Hexyne-1

[0063] (0.1) Preparation of n-bromobutane

[0064] Put 2.335kg of n-butanol, 7.5kg of hydrobromic acid, and 1L of concentrated sulfuric acid into the reaction kettle, heat and reflux for 4 hours, distill the crude product, wash it with concentrated sulfuric acid, water, and dilute alkali water, and then wash it with anhydrous Calcium chloride is dried and the product is distilled off. Repeat twice to obtain 3.31 kg of n-bromobutane on average, the content is greater than 99%, and the yield is 75.9%. spare.

[0065] (0.2) Preparation of Hexyne-1

[0066] Pass about 8L of liquid ammonia into the reaction kettle, add an appropriate amount of ferric nitrate as a catalyst under stirring, add 280g of sodium metal piece by piece under the flow of acetylene, and continue to pass acetylene for 2 hours after the addition, add dropwise 1370g of n-bromobutane, 2.5 At the...

Embodiment 2

[0090] Embodiment two, the sugarcane bar borer sex attractant is used for forecasting:

[0091] The moth comparison test was carried out on live female moths at the same time with the sugarcane bark borer sex attractant and light, and the sugarcane bark borer sex attractant was formulated into a film dosage form with the following formula (weight percentage):

[0092] components

[0093] Dilute cis-11-hexadecenyl acetate, cis-13-octadecenyl alcohol, and cis-13-octadecenyl acetate with solvent acetone, stir well, and mix 2000 films (about 3cm 2 / piece) is put into soaking, and is prepared into a film dosage form for forecasting.

[0094] Test method and effect:

[0095] (1) Select a contiguous sugarcane field with the same sugarcane variety, growth, fertilizer and water management conditions, and an area of ​​more than 30 mu as the experimental field, and evenly set up three sexual attractant traps, one light trap and three live female moth traps , as one repetitio...

Embodiment 3

[0101] Example 3. Using the sugarcane barworm sex attractant to prevent and control the sugarcane barborer - "fascination method" control

[0102] Be formulated with following formula (percentage by weight) the sex attractant " lure tube " tube of sugarcane stalk borer:

[0103] components

[0104] Dissolve cis-11-hexadecenyl acetate, cis-13-octadecenol and cis-13-octadecenyl acetate in n-heptane as a solvent, stir evenly, then pour them into plastic raw materials and mix them until After the sex attractant is basically infiltrated, it is poured into an extruder for processing, drawn into a hollow plastic tube, and cut into a two-pointed oblique tube.

[0105] Test method and effect:

[0106] (1) Select the sugarcane field with consistent sugarcane variety, growth, fertilizer and water management conditions, good isolation conditions, and large-scale contiguous areas (more than 100 mu) as the experimental field; In the control field, 9 monitoring pots were set up f...

Abstract

A sexual attractant for the cane borer is prepared from cis-11-hexadeceneol acetate, cis-13-octadecaneol and cis-13-octadeceneol acetate through proportional mixing. An adhesive sheet for forecasting cane borer and a tube for preventing and eliminating cane borer are also disclosed.

Description

technical field [0001] The invention relates to the technical field of insect sex pheromone synthesis. Background technique [0002] Sugarcane borer is one of the main pests that damage sugarcane. It eats sugarcane with larvae and causes dead shoots or borer damage, which seriously reduces sugarcane yield and sugar content. In addition to the use of agricultural control and physical control, Trichogramma control is also used in production at present, but chemical pesticides are mainly used for control. [0003] Due to the strong resistance of pests to pesticides, the use of chemical pesticides to control sugarcane borer is increasingly ineffective. According to the principle that the sex pheromone released by live female moths has a strong ability to attract male moths of the same species, currently The most reliable control measure is to block the mating by using the sex pheromone secreted by the female moth of the sugarcane borer, that is, the sex attractant.
