Embodiment 5
[0039] Example 5 Laboratory slow-release effect research of the gel-like black beetle slow-release attractant:
[0040] The sustained-release preparation prepared in Example 2 is released under natural conditions, and the samples are recovered every 5 days, and the residual amount of the active ingredient of the sex attractant is measured by ultraviolet spectrophotometry, and the release curve of the relationship between the residual amount and time is obtained ( image 3 ). Depend on image 3It can be obtained that within 65 days, the residual amount and time are in a quadratic trinomial relationship, and the release curve is y=0.0086x 2 -1.4182x+77.969, R 2 = 0.9955. And on the 65th day, the residual amount of the active ingredient of the sex attractant is still 20%, about 5g, which is enough to meet the demand of attracting insects.
