Problems solved by technology

[0011]The existing traps are easy to climb out through the inner wall after catching the longhorn beetle, which affects the effect statistics, and due to rain and other reasons, there will be water in the middle, which will affect the beetle's performance. Survival rate, insect sources in the same area are affected, and the correctness of the results is directly compared

Embodiment 1

[0032] The method for monitoring and preventing Beetleus glabrata using the improved intercepting baffle trap described in Example 1, the male pheromone of Beetleus glabridis is composed of alcohols: 4-(n-heptyloxy)butanyl-1 -Alcohols and aldehydes: 4-(n-heptyloxy)-1-butyraldehyde mixed in a volume ratio of 1:1; the plant volatiles: Z-3-hexen-1-ol, 1-butanol, 1-pentanol, 2-pentanol, ethyl acetate, 3-hexenyl acetate, S-β-pinene, phellandrene; 1 of the androgen pheromone and the plant volatiles: A mixture of 10 (10 μg: 100 μg) was used as a pheromone blend.

Embodiment 2

[0034] The method for monitoring and preventing Beetle glabrata using the improved interception baffle trap described in embodiment 1 or 2, the method for preparing the male pheromone lure core: taking 1 μl concentration is 10 μg / μl and the volume ratio is 1 : 1 pheromone blend, that is, 10 μg male pheromone, put this 10 μg pheromone in the large mouth rubber slow-release pad, then drop 2 drops of hexane, soak the pheromone in the rubber pad for 10 minutes, and wait for hexane After evaporation, tap the rubber slow-release pad with aluminum foil, then put the rubber slow-release pad into a polyvinyl fluoride plastic bag, store it at low temperature, and set aside.

Embodiment 3

[0036] Embodiment 1 or 2 or the method for monitoring and controlling Beetleus glabrata using the improved interception baffle type trap described in embodiment 1 or 2 or 3, the preparation method of the described pheromone and plant volatile composition lure: take 1 μl concentration to be 10 μg / μl and the pheromone blend with a volume ratio of 1:1, that is, after mixing 10μg of male pheromone with 100μg of each plant volatile, the mixture was placed in a large-mouth rubber slow-release pad, and then dropped into 1-10 Drops of hexane, dip this composition into a rubber pad. After 10 minutes, after the hexane has evaporated, tap the rubber slow-release pad with aluminum foil, then put the rubber slow-release pad into a polyvinyl fluoride plastic bag, store it at low temperature, and use it for later use.

Abstract

An improved intercepting baffle type longicorn trap and methods for monitoring and preventing longicorns. After the existing trap catches the longhorn beetle, it is easy to climb out through the inner wall, which affects the effect statistics, and due to rain and other reasons, there will be water in the middle, which will affect the survival rate of the longhorn beetle, and the insect source in the same area will be affected. The results of direct comparison correctness. Using the improved interceptor baffle trap to monitor and control the longhorn beetle, first test the sample plot, and select the male pheromone of the longhorn beetle as the attractant. Select plant volatiles, prepare male pheromone lures, prepare pheromone and plant volatile composition lures, install new ones on traps, hang traps, and perform inspection and maintenance. The present invention provides a Methods for monitoring and controlling long beetles.

Description

[0001] Technical field: The present invention relates to an improved trap for monitoring and preventing forest pests, in particular to an improved trap for monitoring and preventing longhorn beetles, and methods for monitoring and preventing longhorn beetles. The technology belongs to the technical field of forest science and forest protection. Background technique [0002] The existing technology confirms that there are about 30,000 kinds of volatile organic compounds (Volatile organic compounds, VOCs) synthesized by plants through secondary metabolic pathways in the body, which are composed of some organic compounds with a molecular weight of 100-200, such as hydrocarbons, alcohols, ketones A mixture of species, organic acids, nitrogen-containing compounds, and organic sulfur. Plant volatiles are not only signal substances for information exchange between plants, but also important information substances that guide herbivorous insects to identify and locate their hosts.
