Problems solved by technology

Chinese scientific research institutes and enterprises generally use pheromone trapping technology to control diamondback moth. The number of adults trapped is considerable, but the actual control effect is not obvious
The relevant research team of the Chinese Academy of Sciences used rubber tips and microcapsules as releasers to try pheromone technology to control diamondback moth, but the duration of effect was unstable, which affected the actual control effect

Embodiment 1

[0031] The pheromone active ingredient (weight is 950mg) cis-11-hexadecenal (Z11-16CHO), cis-11-hexadecenyl acetate (Z11-16Ac) and cis-11-hexadecenol (Z11-16OH) was mixed according to the weight ratio of 50:20:5, and added into olive oil to form a solution. Wherein, the weight composition ratio of the pheromone component to the olive oil is 1:10. Then, select a polyethylene capillary with an inner diameter of 0.45 mm and a length of 50 cm, quantitatively add the pheromone solution into the capillary with a syringe, and seal it with a sealing machine. The above-mentioned liquid-filled capillary is evenly wound on the bamboo chopsticks to make the oblique silk. Place 20 oblique wires per mu of vegetable field. Three diamondback moth traps were evenly placed in an equilateral triangle in the control area and the misdirection area for monitoring. At 9 am every day, the adult insects were observed and recorded, and the number of traps for the entire generation was counted. Durin...

Embodiment 2

[0033] Other conditions were the same as in Example 1, except that the total weight of the pheromone active ingredients was changed to 3.5 grams, and the prepared Plutella xylostella xylostella was used in a field test. After continuous observation for 30 days, the calculated average tropism rate was 94%.

Embodiment 3

[0036] Other conditions are the same as in Example 1, the pheromone active ingredient is cis-11-hexadecenal (Z11-16CHO), cis-11-hexadecenyl acetate (Z11-16Ac) and cis-11-hexadecenal The weight composition ratio of enol (Z11-16OH) was changed to 50:50:10. The prepared lobed silks of diamondback moth were used in field experiments. After continuous observation for 30 days, the calculated average lobed rate was 82%.

Abstract

The invention discloses a composition of a plutella xylostella pheromone disorientation silk, belonging to the technical field of control of plutella xylostella. The plutella xylostella pheromone disorientation silk comprises effective components of: cis-11-hexadecene aldehyde (Z11-16CHO), cis-11-hexadecene enol acetate (Z11-16Ac) and cis-11-hexadecene enol (Z11-16OH) according to a weight composition proportion of (30-100):(20-80):(0-30). Pheromone components are mixed with a slow release solution to obtain a sex pheromone solution, and the sex pheromone solution is added in a release carrier, so that the plutella xylostella pheromone disorientation silk can be obtained. During the field application, the prepared plutella xylostella pheromone disorientation silk is placed in a field, and is higher than a vegetable surface in position. The plutella xylostella pheromone disorientation silk is used for preventing and controlling the brassicaceous vegetable-crop pest-insect plutella xylostella, and expresses an excellent control effect, and thus the base number of larvae in the field is greatly reduced.

Description

technical field [0001] The invention discloses a composition of diamondback moth pheromone directional silk, relates to the field application of pheromone directional technology in preventing and controlling vegetable pests diamondback moth, and belongs to the technical field of diamondback moth control. Background technique [0002] diamondback moth ( Plutella xylostella (L.)) belongs to Lepidoptera Plutella, mainly damages Brassica cabbage, purple cabbage, broccoli, mustard greens, cauliflower, cabbage, rape, radish and other cruciferous vegetables. Its larvae eat the mesophyll of vegetable leaves, leaving only the epidermis; when they damage the heart leaves of vegetables, the growth of heart buds is hindered, which seriously affects the quality and yield of vegetables. Many factors, such as high reproduction rate, high migration degree, short generation and wide range of hosts, make the control of diamondback moth very difficult. Plutella xylostella has developed serio...
