Problems solved by technology

[0004] Due to the concealment of the living environment of pests, the effect of conventional agricultural and forestry monitoring and prevention and control measures is not ideal, and the population dynamics of pests cannot be discovered in time, and effective measures can be taken in time. At the same time, the large-scale use of chemical pesticides will bring serious "3R" problems, and also greatly endanger food safety, and the residues will increase
Although many studies on sex attractants have been reported, the exact ratio and ratio of the sex attractant components of Litchi dimorphus is not yet clear

Embodiment 1

[0015] The test site is located in Nanning Forestry Research Institute, Guangxi, and the test forest is pure Gemu forest with an area of ​​60 mu. The annual cycle trapping of Litchi dimorpha moth by using the main component of sex attractant Z8-12AC.

[0016] The main component of single attractant Z8-12AC is used to make traps. The trap was hung from January 25, 2018, and data collection for the experiment ended on January 30, 2019. A total of 10 repetitions of the traps were hung, and the distance between the traps was controlled at 15 meters. The amount of insects caught was observed and recorded every 10 days, and the position of each repeated trap was changed one by one, and new sticky traps were used to replace the traps one by one. All the boards were replaced with old sticky boards, and the sex attractant lure core was replaced every 30 days. Count the number of adults trapped on each sticky board, summarize and make the amount of adults trapped every month.

[0017...

Embodiment 2

[0019] Four sex pheromone components are used: ① Z8-12AC ② E8-12AC ③ Z8-12OH ④ Z7-12AC to form 9 sex pheromone attractants with Z8-12AC as the main component.

[0020] Table 1 Combinations of 9 sex attractants

[0021] Table 1 Combination of 9 sex attractants

[0022]

[0023] Note: The same dose of antioxidant was added to the 9 combinations, and the same amount of n-hexane was added to No. 9 lure as CK.

Embodiment 3

[0025] The electrophysiological net response value (mV) of the antennae to each group of compounds was calculated by detecting the antenna potential response (EAG detection) of 9 sex pheromone attractant combinations.

[0026] Table 2 EAG responses of 9 sex attractants

[0027] Table 2 EAG responses of adult antennae to 9 sex pheromone multi-component attractants

[0028]

[0029]

[0030] The data in the table are the mean ± standard error. Those with the same letter after the data have no significant difference after the Duncan multiple range test. Different lowercase letters in the same column indicate significant differences at the 0.05 level, and different uppercase letters indicate extremely significant differences at the 0.01 level. . The same below.

[0031] It can be seen from Table 2 that the EAG net response value of female adults to No. 8 lure reached 0.437mV, and the minimum EAG net response value of the lure was No. 7 lure (0.107mV). is 0.143mV. The EAG...

Abstract

The invention discloses a high-efficiency sex attractant for Cryptophlebia ombrodelta (Lower). According to the sex attractant, Z8-12AC is used as a main component; the sex attractant taking Z8-12OH and Z7-12AC as synergistic auxiliary components is prepared from the following components in percentage by volume: 60 to 90 percent of the main component Z8-12AC, 10 to 40 percent of the synergistic auxiliary component Z8-12OH and 5 to 20 percent of the synergistic auxiliary component Z7-12AC. The sex attractant can be used for accurately monitoring the adult population dynamic state of the Cryptophlebia ombrodelta (Lower), efficiently trapping a large number of Cryptophlebia ombrodelta (Lower), and remarkably improving the effect of comprehensively preventing and controlling pests, avoids environmental pollution, is safe and non-toxic to people and livestock, and has a wide application prospect in prevention and control of Cryptophlebia ombrodelta (Lower) pests of agricultural and forestrycrops.

Description

technical field [0001] The invention discloses a sexual attractant for borer pests, in particular to a high-efficiency attractant for the litchi-shaped toricula moth. [0002] technical background [0003] Cryptophlebia ombrodelta (Lower), belonging to the order Lepidoptera, Toriidae, and the genus Cryptophlebia, is a species that harms more than 10 kinds of timber forests and The important borer pests of economic trees mainly feed on the young shoots, shells and seeds of host plants with larvae, causing new shoots and branches, and can also cause fruit to fall off. The worm can be distributed with the host in my country from north to Henan and south to Hainan. [0004] Due to the concealment of the living environment of pests, the effect of conventional agricultural and forestry monitoring and prevention and control measures is not ideal, and the population dynamics of pests cannot be discovered in time, and effective measures can be taken in time. At the same time, the lar...
