Problems solved by technology

Although the use of sex lures is one of the means of forecasting and control at the present stage, these sex lures can only lure a part of the males, and the untrapped males can make the females lay eggs through multiple matings, and the eggs laid It is the female insects that are harmful, so the sex attractant can play the role of forecasting and reducing the number of insects, but it is not very effective as a control method

Embodiment 1

[0033] Y-tube behavior response

[0034] The experiment was carried out under natural light environment conditions with a room temperature of 24±1°C and a relative humidity of 40±5%. Before the experiment, the Y-shaped olfactometer (Y-shaped tube) was cleaned with acetone and n-hexane successively. Prepare linalool oxide with n-hexane to prepare three concentration gradients of 0.1 μg / μl, 1 μg / μl and 10 μg / μl of the sample to be tested, and use n-hexane as a control, take 10 μl of the sample to be tested and n-hexane to drop in two places respectively. On different pieces of filter paper, put two filter paper strips into the odor source device bottles on both sides of the Y-shaped tube, turn on the atmospheric sampler and make the air flow rate in the Y-shaped tube 100ml / min, and then put the eclosion within 1 day Fall armyworm adults were put into the release tube and observed for 5 minutes. If fall armyworm first selected an arm of more than 5cm and lasted for more than 30s...

Embodiment 2

[0037] Y-tube behavior response

[0038] Oxidized linalool was formulated with n-hexane, natural vegetable oil, dioctyl terephthalate and dichloromethane to prepare a test sample of 1 μg / μl, and each corresponding solvent was used as a control.

[0039] Other operations are the same as in Example 1.

[0040] The behavioral response of the Y-tube results in the following image 3 , the Chi-square test results showed that several solvents dissolved linalool oxide had a significant attractive effect on female insects.

Embodiment 3

[0042] EAG relative response value

[0043] EAG (Syntech, Germany) was used to measure the electrophysiological responses of male and female adults of Spodoptera frugiperda to different concentrations of oxidized linalool. The specific operation steps are as follows: prepare the oxidized linalool with n-hexane to prepare three concentration gradients of 0.1 μg / μl, 1 μg / μl and 10 μg / μl of the samples to be tested, and use n-hexane as a control, and take 10 μl of the samples to be tested each time Or the control drops on the filter paper, and then put the filter paper into the sample tube. The antennae of adults of Spodoptera frugiperda were cut off from the base, and a small part (about 1 mm) of the end of the antennae was cut off, and the two ends of the antennae were respectively glued to the fork-type electrodes with conductive adhesive. Adjust the continuous flow of air at the antenna to 5ml / s. When testing, switch the continuous air flow of air to the stimulating air flo...

Abstract

The present invention relates to the application of oxylinalool in attracting fall armyworm and the composition containing it. The composition includes linalool oxide, a solvent, a photostabilizer and an antioxidant.

Description

technical field [0001] The invention relates to the application of oxylinalool in luring Spodoptera frugiperda. Background technique [0002] Fall armyworms originated in Central and South America and spread to North America. In January 2016, it was first discovered in Nigeria in West Africa. Due to its lack of natural enemies and strong ability to reproduce and migrate, it swept across 44 sub-Saharan African countries within two years. In 2018, fall armyworm spread into Asia and spread rapidly in India, Sri Lanka, Bangladesh, Thailand, Myanmar, Vietnam, and Laos in South and Southeast Asia. [0003] Spodoptera frugiperda has strong reproductive ability, an average female can lay about 1,000 eggs, and can produce up to 2,000 eggs; it has a wide range of hosts and can feed on 353 species of plants in 75 families; it migrates quickly, and adults can migrate overnight with the help of atmospheric circulation More than 100 kilometers; gluttony, 5-6 instar larvae eat a lot, the...
