Embodiment 1

[0020] From July 5 to 15, 2021, the indoor attraction effect test of the small cutworm attractant lure was carried out at the Institute of Zoology, Guangdong Academy of Sciences.

[0021] Components of the attractant: 2-ethylhexanol, (2E,6E,11Z)-3,7,13-trimethyl-10-(2-propyl)-2,6,11-cyclotetradecyl The purity of triene-1,13-diol, undecane, styrene, dibutyl phthalate and hexadecane is above 99%.

[0022] Using n-hexane as solvent, prepare 2-ethylhexanol, (2E,6E,11Z)-3,7,13-trimethyl-10-(2-propyl)-2,6,11-cyclodeca Tetracarbatriene-1,13-diol, undecane, styrene, dibutyl phthalate and hexadecane solutions, concentrations of 5 mg / ml and 10 mg / ml were added dropwise to 200 μg Rising on the septum of the rubber stopper cleaned with n-hexane, the attractant lure is made after the n-hexane volatilizes. Put the lure core made of attractant into aluminum foil, seal it, and store it at -20°C.

[0023] Mix each component according to the composition in Table 1 and dissolve in n-hexane to...

Embodiment 2

[0032] The small cutworm attractant of this embodiment includes the following components by weight: 0.8 parts of 2-ethylhexanol, (2E,6E,11Z)-3,7,13-trimethyl-10-(2-propane 8 parts of -2,6,11-cyclotetradecatriene-1,13-diol, 0.3 parts of undecane, 3 parts of styrene, 2.5 parts of dibutyl phthalate, 0.8 parts of hexadecane Parts, mixed by weight, dissolved in n-hexane to make a n-hexane solution of multi-component attractant, the solution concentration is 20 mg / ml, drop 200 microliters on the septum of the rubber stopper cleaned with n-hexane , After the n-hexane volatilizes, the synergist lure is obtained. Put the prepared multi-component attractant core into aluminum foil, seal it, and store it at -20°C.

[0033] From May 3 to 14, 2021, in Huaning County, Yuxi City, Yunnan Province, choose a time when it is humid or just after rain, and the temperature is suitable (about 25°C) to conduct experiments in the tobacco field, and take multi-component attractants in the attraction a...

Abstract

The invention discloses an attractant composition for agrotis ypsilon larvae and an application of the attractant composition. The attractant composition comprises the following components in parts by weight: 0.1 to 0.8 part of 2-ethylhexanol, 2 to 8 parts of (2E,6E,11Z)-3,7,13-trimethyl-10-(2-propyl)-2,6,11-cyclotetradecatriene-1,13-diol, 0.08 to 0.3 part of undecane, 1 to 3 parts of styrene, 0.8 to 2.5 parts of dibutyl phthalate and 0.1 to 0.8 part of hexadecane. The synergist provided by the invention is low in component price, can reduce the cost of making a lure, and is suitable for popularization and promotion.

Description

Technical field: [0001] The invention belongs to the technical field of pest monitoring and trapping, and in particular relates to an attractant composition for small cutworm larvae and an application thereof. Background technique: [0002] Agrotis ipsilon belongs to Lepidoptera: Noctuidae. It is an important underground pest. Its host plants are very extensive. Except for aquatic plants such as rice, it can kill the seedlings of almost all plants. Food is harmful. Its larvae are the main pests at the seedling stage of tobacco. They cause the death of the whole plant of tobacco by gnawing on the stems of the seedlings, and in severe cases cause the destruction of the species. At present, chemical pesticides are still the main method of controlling underground pests, but chemical pesticides cause environmental pollution due to high toxicity and high dosage; green prevention and control using ecological methods can reduce the use of chemical pesticides and protect human healt...
