Problems solved by technology

It can be seen that the above two types of lures are in direct contact with the operator when they are used. Due to the sensitivity of pheromone attractant products, this process is very easy to contaminate the attractant lures, resulting in no or poor lure effect. The hole and groove mode used for fixing also has the disadvantage that the lure will fall off during use, and there is a risk of stabbing the user when the iron wire penetrates the rubber stopper

Embodiment 1

[0044] Cis-8-dodecene acetate, trans-8-dodecene acetate, and cis-8-dodecenol weight composition ratio are 86:6:2, and it is combined with antioxidant, anti The ultraviolet agent is fully mixed according to the mass ratio of 5:0.5:0.01:0.4; then added to the inorganic filler, the mass ratio is 1:500; it is fully stirred to make the liquid evenly adhere to the inorganic filler; On this basis, add viscose with an equal mass ratio, and fully stir in a constant temperature oil bath at 40°C, so that the inorganic filler particles carrying the active ingredient of the sex pheromone of the pear borer worm are fully contacted and wrapped with the viscose; A paste-like finished product can be obtained; if the stirring resistance is relatively large, an appropriate amount of ethanol can be added.

Embodiment 2

[0046] Other conditions are the same as in Example 1, the pheromone active ingredient is changed to cis-8-dodecene acetate, trans-8-dodecene acetate, cis-8-dodecenol weight composition ratio It is 85:8:2; a pasty finished product is obtained;

Embodiment 3

[0048] Other conditions are the same as in Example 1, the pheromone active ingredient is changed to cis-8-dodecene acetate, trans-8-dodecene acetate, cis-8-dodecenol weight composition ratio It is 102:9:1; a pasty finished product is obtained;

[0049] The distribution ratio of each group of embodiment is shown in the table below:

[0050]

[0051] The above experiments, among them, the experimental period is from June 5, 2018 to July 1, 2018, and the experimental location is the experimental site of Shaanxi Yangling Vocational and Technical College.

Abstract

The invention discloses novel grapholitha molesta adult sex pheromone attractantpaste and a preparation method and an application method thereof. The paste is prepared from cis-8-dodecenyl acetate, trans-8-dodecenyl acetate, cis-8-dodecenol, an auxiliary agent, a matrix and the like in a mass ratio of (0-10): (0-1): (0-0.1): (0-1): (0-100), and the field lasting period of the paste prepared by themethod is not less than 4 weeks. The paste attractant prepared by the method is matched with a special trap for use, can achieve the same attractive effect as a traditional attractant paste, and is convenient to use; the attractant paste of the invention can replace an existing rubber plug and an existing grapholitha molesta sex pheromone lure made of plastic capillary materials.

Description

technical field [0001] The invention relates to the technical field of fruit tree pest control, and more specifically relates to a novel sex pheromone attractant ointment, a preparation method and a use method of the pear borer moth. Background technique [0002] Pear small borer, Grapholitha molesta (Busck), a kind of insect of the genus small borer in the family Tortridoidae, is a kind of. It is a worldwide fruit tree pest. The larvae damage the fruit and mostly enter from the calyx and stalk depression. In the early stage, there is insect excrement outside the bore hole, and in the late stage, there is no insect excrement. The larvae penetrate directly into the fruit core, and under high humidity, the surrounding holes often turn black and rot and gradually expand, commonly known as "black plaster". Most of the larvae damage the young shoots from the base of the upper petiole to the pith, and then move downward to the lignified part. The holes flow glue and there are ins...
