Abstract
An environmentally friendly type insecticide is prepared from d-limonene (C10H16) (2-6 wt.%) and diluent (93-98 wt.%). Said d-limonene is extracted from tangerinin peel oil. Its advantages are high effect, preventing rot of dead insects, and natural fragrance.
Description
The present invention relates to a kind of composition, especially a kind of is the insecticide of key component with mandarin oil purification thing citrene and edibility mineral white oil.
The method of traditional kill harmful insect mostly is the stomach poisoning agent of chemical type, neural poisoning agent or respiratory tract poisoning agent, and these insecticides all can have a negative impact to environmental factor and health.
The purpose of this invention is to provide a kind of stable, to insect knock down and kill the environmental protection type plant source sanitary insecticide composition that speed can reach the chemical insecticide index, environment protection type insecticide for sanitary purpose of the present invention can be avoided in the desinsection process environmental factor and health being had a negative impact.
The present invention is achieved in that a kind of environment protection type insecticide for sanitary purpose, by d-citrene (C10 H16, its LD50＞5000mg/kg) form with thinner, wherein the d-citrene accounts for the 2-6% of gross weight, thinner accounts for the 98-93% of gross weight, and described d-citrene can be obtained from mandarin oil in purification; Described thinner can adopt the solvent in the prior art, as mineral white oil, deodorized kerosine or ethanol, citrene is distributed in the thinner, can form the dispersion liquid that transparent appearance is arranged that insect is had killing action.
Have now found that the carbon molecular number is that (molecular formula is: CnH2n+2, n=10-18 for the mineral white oil of 10-18, initial boiling point: 80 ℃, flash-point is 87 ℃, arene content＜0.5%, be the transparency liquid of no color or smell) can be used as the carrier that dilutes citrene, and it dissolves characteristic of wax fast.Just can be used for generally having all kinds of insects of wax watertight composition.Adopt the low boiling white oil as one of key component among the present invention, can increase the evaporation rate of insecticide.D-citrene in the insecticide dissolves the wax watertight composition on the respiratory of insect device rapidly, and then its respirator is stopped up, and is choked to death fast.The worm corpse that loses wax waterproof top layer at room temperature further dewaters shrivelled, the antibacterial action of citrene and natural flavor, and certain bacteriostasis of white oil, prevented the worm corpse rot go mouldy and eliminated the off-odor of some insect such as cockroach, reached purpose of the present invention.
In order to increase the speed of knocking down to insect, can also add the knock down agent of weight among the present invention less than insecticidal total weight 1%, described knock down agent is made up of tetramethrin and rich d-trans Allethrin 93.
The present invention is further illustrated below in conjunction with embodiment.
A kind of environment protection type insecticide for sanitary purpose of the present invention, (wherein the d-citrene accounts for the 2-6% of gross weight for C10 H16, its LD50＞5000mg/kg) form with thinner by the d-citrene, thinner accounts for the 98-93% of gross weight, and described d-citrene can be obtained from mandarin oil in purification; Described thinner can adopt the solvent in the prior art, in a better embodiment of the present invention, it is the mineral white oil of 10-18 that thinner has adopted the carbon molecular number, and citrene is distributed in the thinner, can form the dispersion liquid that transparent appearance is arranged that insect is had killing action.In order to increase the speed of knocking down to insect, can also add the knock down agent of weight among the present invention less than insecticidal total weight 1%, described knock down agent is made up of tetramethrin and rich d-trans Allethrin 93.
Have now found that the carbon molecular number is that (molecular formula is: CnH2n+2, n=10-18 for the mineral white oil of 10-18, initial boiling point: 80 ℃, flash-point is 87 ℃, arene content＜0.5%, be the transparency liquid of no color or smell) can be used as the carrier that dilutes citrene, and it dissolves characteristic of wax fast.Just can be used for generally having all kinds of insects of wax watertight composition.Adopt the low boiling white oil as one of key component in the embodiments of the invention, can increase the evaporation rate of insecticide.D-citrene in the insecticide dissolves the wax watertight composition on the respiratory of insect device rapidly, and then its respirator is stopped up, and is choked to death fast.The worm corpse that loses wax waterproof top layer at room temperature further dewaters shrivelled, the antibacterial action of citrene and natural flavor, and certain bacteriostasis of white oil, prevented the worm corpse rot go mouldy and eliminated the off-odor of some insect such as cockroach, reached purpose of the present invention.
According to experiment, the included ratio of active ingredient citrene in composition among the above-mentioned insecticides, be respectively 1. 2% at 1., 2. and 3. three assembly Fang Zhongke, 2. 4% and 3. 6%, with the most representative aquatic insect predacious diving beetle is experimental subjects, its on average the speed of knocking down be respectively about 3 minutes 30 seconds, 2 minutes and 18 seconds and 1 minute and 35 seconds, final all dead.
Be that experimental subjects averages and kills speed trial with the cockroach, per 10 of medium sized cockroach is a control group, totally 3 groups, 1., 2., 3. sprays respectively with composition by prescription, with little wet be the degree of cockroach body surface, it is on average knocked down and kills the time and can see the following form to witness observation:
| On average knock down the time (second) | On average kill the time (branch) | ||
| The 1st control group | ????12 | ????30 | Prescription 1. |
| The 2nd control group | ????8 | ????11 | Prescription 2. |
| The 3rd control group | ????5 | ????5 | Prescription 3. |
Therefore, 2. preferred version for filling a prescription.
For the odor characteristics of improving composition and the smell of eliminating the worm corpse, can also add gamma lactone (γ-lactone, C9 H16 O2) and peach aldehyde (Peach-Aldehyde, C11 H20O) in the prescription composition 2..The 2. middle percentage by weight of all components in composition of prescription is respectively:
Citrene--------------------4.00%
Gamma lactone-------------------0.02%
Peach aldehyde----------------------0.05%
Tetramethrin--------------------0.20%
Rich d-trans Allethrin 93--------0.10%
Mineral white oil--------------all the other
Said components stirred for several at normal temperatures minute can obtain having the composition that natural lemon fragrance is arranged of transparent appearance.
2. mosquito and fly are sprayed with prescription, almost knock down immediately and death in 5 seconds.
2. the soup of preparing by prescription carries out the test of pesticide effectiveness in Chinese Military Medical Science Institute, its result such as following table:
