Problems solved by technology

Dot application of a mixture of dichlorvos and diesel oil is labor-intensive and causes leakage
In the forest land where the spot borer occurs seriously, the excessive use of diesel oil also poses the risk of forest fires
However, the cost of trunk injection control is high, and the control effect is not obvious

Embodiment 1

[0037] Example 1 Extraction and identification of the sex pheromone of Pinus sylvestris sylvestris

[0038] 1. Extraction of sex pheromones

[0039] Collect the gelatinous mass containing advanced larvae and pupae in places where the spot borer occurs seriously, put them into large net cages in the forest, and wait for the larvae to pupate and emerge under natural environmental conditions. Use virgin female moths 2-3 days after eclosion, and lightly press the end of the abdomen with your fingers 5-6 hours after entering the dark period to make the sex pheromone glands protrude, then cut off the glands, and quickly put them into the moth containing 1.0ml In a pointed test tube with n-hexane, after leaching for half an hour, the nitrogen gas was concentrated to 20-50 μl, and stored at -20°C for later use.

[0040] 2. Analysis of identifying pheromones

Embodiment 2

[0044] Example 2 Production of sex pheromone lure core for Pinus sylvestris sylvestris sylvestris and moth lure test in the forest

experiment example 1

[0046] 1. Make lures (without antioxidants)

[0047] Using rubber ( Figure 5 ) as the lure slow-release carrier, and the solvent is n-hexane. Add 100 μl of the prepared sex pheromone composition solution of Pinus sylvestris sylvestris to each lure.

[0048] 2. Moth lure test in the forest

[0049] The moth trap test in the forest was carried out at the two sites of Xinjiang Experimental Forest Farm (A) and Fuyu Forest Farm (B) in Qiqihar City, Heilongjiang Province at the same time. The test date was from the beginning of July to the end of July 2020. The traps were triangular traps. Each formula of the sex pheromone composition of Pinus sylvestris sylvestris was repeated 6 times, and the traps were hung about 1.8 meters above the ground, and the distance between the traps was about 40 meters, and the traps were recorded every 3 days. moth volume. The formula of the sex pheromone composition of Pinus sylvestris sylvestris is shown in Table 1:

Abstract

The invention provides a sex pheromone composition of sylvestris sylvestris sylvestris sylvestris and its lure and application. The sex pheromone composition of the present invention comprises trans-11-hexadecenal, cis-11-hexadecene acetate and cis 3, cis 6, cis 9, cis 12, cis 15 ‑Pentacosapentaene, and based on the above-mentioned sex pheromone composition, the sex pheromone lure core of Pinus sylvestris sylvestris was developed, which can effectively trap and kill the male moth of Pinus sylvestris sylvestris. The trapping effect of the male moth is significantly higher than that of the female moth (up to 3 times), which can be applied to the forecasting of the moth and the green control of the moth, avoiding or reducing the use of chemical pesticides, thereby reducing pollution and protecting the environment , has significant economic, social and ecological comprehensive benefits.

Description

technical field [0001] The invention relates to the field of prevention and control of agricultural and forestry pests, in particular to a sex pheromone composition of sylvestris sylvestris sylvestris sylvestris and its lure and application. Background technique [0002] Pinus sylvestris moth, named Dioryctria mongolicella Wang&Sung in Latin, belongs to the genus Dioryctria Zeller of the family Pyralidae in the order Lepidoptera. my country is mainly distributed in Heilongjiang, Jilin, Inner Mongolia and other places. It damages many kinds of pine trees. The larvae invade through the wounds of the branches and feed on the phloem of the trunk and large branches. The damaged parts flow a lot of fat, and form a gelatinous mass mixed with brown insect droppings outside the borehole. When it is seriously damaged, the gelatinous group can condense into piles. The normal growth of pine trees is affected after being damaged, and the trunk and large branches are easily broken from ...
