Problems solved by technology

The existing black beetle attractant lure (ZL201120387584.4) uses the active ingredients of its sex attractant to be adsorbed on absorbent cotton, hung in the field, and traps male adults who come to mate. This method is efficient and targeted , has a very broad market prospect, but the use of absorbent cotton absorbing lures, the volatilization rate is extremely fast and the release is uneven, and it is necessary to replace the lures in the field every day, which artificially increases the amount of labor and restricts the further promotion of this technology among farmers.
There are currently no commercially available slow-release scarab attractants for long-term release

Embodiment

[0023] Example: Preparation of the paste-like slow-release preparation (30 parts) of the black-branched beetle sex attractant

[0024] Step (1)—preparation of the solid content of the sustained-release agent: weigh 448g of L-isoleucine methyl ester, 300g of β-cyclodextrin, 60g of PEG, and 60g of microcrystalline cellulose (6000), and pass through a 0.4mm aperture sieve respectively;

[0025] Step (2)—preparation of the liquid components of the sustained-release preparation: measure (R)-(-)-linalool 75g, 90% ethanol 10ml, and mix well;

[0026] Step (3) - mixing of solid components: mixing the solid components obtained in step (2) in a mixing mixer according to the method of equal addition;

[0027] Step (4) - mixing of solid and liquid components: add the liquid components obtained in step (2) into the mixing mixer according to the method of equal addition and fully mix with the mixture obtained in step (3) until a uniform paste mixture is formed, That is, the pasty sustained...

experiment example 1

[0030] Experimental Example 1: Research on the slow-release effect of the pasty black beetle sex attractant slow-release preparation in the laboratory

[0031] The sustained-release preparation prepared in the example was released under natural conditions, and the samples were recovered regularly to measure the residual amount of the sex attractant, and the release curve of the residual amount versus time was obtained. Depend on figure 1 , 2 It can be obtained that the residual amount and time have a quadratic trinomial relationship.

[0032] The natural conditions: condition 1—temperature 12±6℃, humidity 15~35%; condition 2—temperature 20±5℃, humidity 20~45%

experiment example 2

[0033] Experimental example 2: Field trapping effect of this pasty black beetle sex attractant slow-release preparation

[0034] The test site is located in the peanut test field in Xiangyang, Hubei, and the test time is from July to August 2013 (excluding rainy days). The conventional absorbent cotton-type lure was used as a control, and the experiment was repeated 4 times. The distance between the traps is 60 meters. During the experiment, the absorbent cotton lures were replaced once every unearthed day, and placed in the collection bag of each trap before 7:00 in the evening, and the slow-release dosage forms were not replaced. Investigate and record the number of insects lured in each trap every night.

[0035] Depend on image 3 It can be obtained that the slow-release preparation of the pasty black beetle sex attractant has a good effect on attracting insects, and the duration of the effect can reach 30 days.

Abstract

The invention relates to the preparation field of sustained-release preparations, in particular to a pasty Holotrichia parallela sex attractant sustained-release preparation and a preparation method thereof. The pasty Holotrichia parallela sex attractant sustained-release preparation is prepared from sex attractant effective constituent, an auxiliary material A, an auxiliary material B, an auxiliary material C and an auxiliary material D in certain proportion, wherein the sex attractant effective constituent and the auxiliary materials A, B and C are solid, and the auxiliary material D is liquid. Compared with an existing sex attractant preparation, the sustained-release preparation has the advantages of simple preparation process, reliability in dosage preservation, and obvious release rule, and environment-friendly effect; the release curve of the sustained-release preparation meets the quadratic trinomial rule, and the pasty Holotrichia parallela sex attractant sustained-release preparation has trapping effect up to 30 days on Holotrichia parallela, overcomes the disadvantages of short lasting period and wasted labor cost of an existing dosage form, has feasibility for large-scale production, facilitates large-scale promotion in farmers and has obvious economic significance and ecological significance.

Description

technical field [0001] The invention relates to the field of preparation of sustained-release preparations, in particular to a paste-like slow-release preparation of a black beetle sex attractant and a preparation method thereof. Background technique [0002] Diablo beetle is one of the most harmful pests in peanuts, soybeans, sweet potatoes, corn and other crops. Its adults feed on the leaves of crops and forest trees and have the characteristics of gluttony, while larvae grubs do damage underground and are highly concealed. Strong adaptability, so it has always been the focus and difficulty of pest control. In recent years, with the development of agricultural production in our country, its occurrence area has increased rapidly, especially in peanut fields, when the number of insects per hectare is as high as hundreds of thousands or even millions, often resulting in large-scale failure of peanuts. According to five consecutive years of follow-up investigations in Shandon...
