Problems solved by technology

[0003] In terms of control, since the high-stalk crops of the sunflower genus are controlled by chemical spraying, it is difficult to operate, especially in the later period when the plants are tall and tall, chemical control can easily cause poisoning of operators
It is also possible to release natural enemies, such as releasing Trichogramma in the field, but the operation period is long, the operation is inconvenient, and it is difficult to control its effect

Embodiment 1

[0014] Example 1: 0.5 mg cis 13-octadecenal, 0.5 mg cis 11-hexadecenal, 0.1 mg cis 9, trans 12-tetradecadienal, 0.1 mg cis 9-tetradecenal Mix alkenal and 0.4 mg antioxidant to obtain the sex attractant of sunflower borer. It can be diluted with hydrocarbon organic solvent petroleum ether or n-heptane, and then inject the sexual attractant of sunflower borer into a plastic tube with an inner diameter of 0.1 mm with a syringe, and seal both ends to obtain a lure, and then put the lure into the trap.

Embodiment 2

[0015] Example 2: 0.4mg cis 13-octadecenal, 0.6mg cis 11-hexadecenal, 0.1mg cis 9, trans 12-tetradecadienal, 0.1mg cis 9-tetradecenal Mix alkenal and 0.4 mg antioxidant to obtain the sex attractant of sunflower borer. It can be diluted with hydrocarbon organic solvent petroleum ether or n-heptane, and then inject the sex attractant of sunflower borer into the sleeve-type composite rubber plug with a syringe to obtain the lure core, and then put the lure core into the trap.

Embodiment 3

[0016] Example 3: 0.4mg cis 13-octadecenal, 0.6mg cis 11-hexadecenal, 0.2mg cis 9, trans 12-tetradecadienal, 0.1mg cis 9-tetradecenal Mix alkenal and 0.4 mg antioxidant to obtain the sex attractant of sunflower borer. It can be diluted with hydrocarbon organic solvent petroleum ether or n-heptane, and then inject the sex attractant of sunflower borer into the sleeve-type composite rubber plug with a syringe to obtain the lure core, and then put the lure core into the trap.

Abstract

The invention relates to an attractive core of an insect sex attractant and discloses an attractive core for preventing and controlling homoeosoma nebulella hubner. The attractive core comprises a sustained-release carrier and a sex attractant contained in the sustained-release carrier, wherein the sustained-release carrier is a cuff-type rubber plug or a plastic tube with internal diameter of 0.1 to 3 mm; and the sex attractant comprises 0.1 to 1.0 mg of cis-13-octadecene aldehyde, 0.1 to 1.0 mg of cis-11-hexadecene aldehyde, 0.1 to 1.0 mg of cis-9-trans-12-tetradecadienoic aldehyde, 0.1 to 1.0 mg of cis-9-tetradecene aldehyde and a proper amount of antioxidant. A field moth-trapping experiment shows that the attractive core of the insect sex attractant has a strong action of attracting the males of the homoeosoma nebulella hubner in the field, and the change of the moth-trapping quantity can reflect the syngenetic succession of the homoeosoma nebulella hubner in the field timely and accurately. The attractive core for preventing and controlling the homoeosoma nebulella hubner has the advantages of safe and environmentally-friendly use, convenient operation, obvious preventing and controlling effect, no harm to human beings, livestock and environments and obvious social and ecological benefits.

Description

technical field [0001] The invention relates to an insect attractant lure core. In particular, it relates to a lure used for preventing and controlling the sunflower borer. Background technique [0002] Homoeosoma nebulella Hubner, also known as Homoeosoma nebulella Hubner, belongs to Lepidoptera and belongs to the family Lepidoptera. In my country, it is mainly distributed in Xinjiang, Heilongjiang and Jilin. In the past two years, it has also caused harm to the Hetao area of ​​Inner Mongolia, causing serious losses to farmers' economic income. It mainly eats sunflower seeds with larvae, and also bites flower discs and sepals. It often eats flower discs into many tunnels, and fills the tunnels with bitten debris and feces to cause pollution. After rain, the flower discs and seeds are moldy and rotten. Seriously affect yield and quality. The sunflower borer has two generations per year, and mainly damages sunflowers, Chrysanthemum chrysanthemums and wild Compositae plants...
