Problems solved by technology

Due to the lack of an effective monitoring method, the insect situation cannot be grasped in a timely manner, which sometimes causes a large number of outbreaks and causes the death of pine trees in patches.
Despite efforts, no sex attractants or pheromones have been found for this insect

Effect test

Embodiment 1

[0038]This example is a control experiment. From June 19 to July 2, 2001, a test was carried out in Zhenyuan County, Yunnan Province on the moth-attracting effect of different components of lure cores on Simao pine caterpillars. Most of the pine forest in the experimental area is composed of Simao pine with a height of about 20 meters, and also contains a small amount of other short broad-leaved trees. Make the following test substances into hexane solution (20 mg / ml): cis 5, trans 7-dodecadienol (Z5, E7-12: OH), cis 5, trans 7-dodecadienol Acetyl acetate (Z5, E7-12: OAc); Then these ingredients are either individually or mixed and dripped on the cuff rubber stopper with a micro syringe according to the proportioning and dosage of each ingredient shown in Table 1. After the hexane volatilizes, add 100 microliters of heptane dropwise, so that the attractant components can penetrate into the inside of the rubber septum. The prepared lures are stored in a freezer at -20°C for f...

Embodiment 2

[0043] The test site and time were the same as in Example 1. In order to measure a kind of Simao pine caterpillar sex pheromone analogue, whether Z5, E7-12:OPr has synergistic effect to two kinds of pheromone components, Z5, E7-12:OAc and Z5, E7-12:OH, the following The test substance is made into hexane solution (20 mg / ml): Z5, E7-12: OH), Z5, E7-12: OAc, cis 5, trans 7-dodecadielyl acrylate (Z5, E7-12:OPr). Then by the dosage of each composition shown in Table 2, these compositions are mixed and dripped on the cuff type rubber stopper with a micro-syringe, and the lure core A does not add any composition, as a contrast. After the hexane volatilizes, add 100 microliters of heptane dropwise, so that the attractant components can penetrate into the inside of the rubber septum. The prepared lures are stored in a freezer at -20°C for future use. The mode and method of the field test are the same as in Example 1. It can be seen from Table 2 that Z5, E7-12:OPr is added to a cer...

Embodiment 3

[0047] The purpose of this embodiment is to further optimize the Simao pine caterpillar sex attractant:

[0048] A field experiment was conducted in Zhenyuan County, Yunnan. The first purpose was to determine how much Z5 should be added to the two basic attractant components. E7-12:OPr had the best moth-attracting activity. Whether cis-5, trans-7-dodecadienal (Z5, E7-12: Ald) and cis-5-dodecene acetate (Z5-12: OAc) have similar chemical structure to Simao pine caterpillar Sex attractants have a synergistic effect. Make the following test substances into hexane solution (20 mg / ml): Z5, E7-12: OH, Z5, E7-12: OAc, Z5, E7-12: OPr, Z5, E7-12: Ald, Z5-12: OAc; Then these components are mixed and dripped on the cuff type rubber stopper with a micro syringe according to the dosage of each component shown in Table 3. After the hexane volatilizes, add 100 microliters of heptane dropwise, so that the attractant components can penetrate into the inside of the rubber septum. The prepare...

Abstract

The invention discloses a Premna Dendrolimus attractant and induced core and making method, which comprises the following parts corresponding to the weight percentage of attractant: 40%-80% cis-5, trans-7-dodecadiene acetate, 35%-10% cis-5, trans-7-dodecadienol, 12. 5%-5% cis-5, trans-7-dodecadiene propionic ester and 12. 5%-5% cis-5-dodecadiene acetate, wherein the Dendrolimus attractant can be dissolved in the hexane or heptane solution to make the density at 20-60mg / ml, which is added on the diaphragm of cuff-typed composite rubber carrier; the attractant can induce male moth during the entire adult stage, which makes female moth loss mating opportunity. The invention can predict and forecast the occurrence of pest, which reduces quantity of the next generation quantity with simple method to be spreaded widely.

Description

technical field [0001] The invention relates to an attractant for the monitoring and control of pine caterpillars, in particular to an attractant and lure core for monitoring and control of simao pine caterpillars with applied pheromones and a preparation method thereof. Background technique [0002] Population monitoring and forecasting of forest pests is an extremely important part of pest control. Due to the large distribution area of ​​the forest and the changeable topography and topography, manual direct investigation is often limited, so it is often impossible to grasp the insect situation in time, resulting in a large outbreak of pests. Many insects secrete sex pheromones and use them to lure individuals of the opposite sex of the same species for mating purposes. Sex pheromones are usually composed of more than one chemical substance with a specific structure in a certain proportion. Because of their importance in pest monitoring and control, many insect sex pherom...
