Embodiment 1

[0013] Determination of Release Time Using Hexyl Butyrate as Tropical Agent

[0014] Put the 10% chlorinated paraffin solution containing 5 mg of hexyl butyrate in a polyethylene (PVC) vial for 3 months, and detect by gas chromatography that 50% of the hexyl butyrate remains.

Embodiment 2

[0016] Preparation of trotropic agent release device

[0017] Use a conventional PVC pipe with an inner diameter of 0.5-1mm and a wall thickness of about 0.05mm. Inject a 10% chlorinated paraffin solution containing 5-15mg of hexyl butyrate into the PVC pipe, and add 1-5mg of 2,6-di Tert-Butyl-4-Methylphenol (BHT) or Vitamin E, both ends sealed as trotropic agent release device.

Embodiment 3

[0019] The test site selects plots in which Lygus melanogaster and Lygus three-spotted stinkbug break out simultaneously, and the release device prepared in Example 2 is directly wound or fixed on the crop branches with thin wires, and the number of anti-pheromone release devices set in each hectare field is 300 -800 pieces, tested after 30 days.

[0020] Hexyl butyrate is slowly released into the field through the pipe wall. When the amount of hexyl butyrate dispersed in the air in the field reaches a certain level, it can interfere and block the intraspecific chemical communication between Lygus chinensis and Lygus trispotica, and reduce the Mating rate, for the purpose of reducing its population size.

[0021] Among them, the specific dosage and placement quantity of the nootropic agent release device were set for 3 repetitions, and the mating inhibition rate was averaged. Examples of the specific dosage and placement quantity of the nootropic agent release device and their...

Abstract

The invention discloses a method of using sex pheromone isotropic agents to prevent and cure adelphocoris suturails and adelphocoris taeniophorus and belongs to the technical field of agricultural insect prevention and cure. The method of using the sex pheromone isotropic agents to prevent and cure the adelphocoris suturails and the adelphocoris taeniophorus is a new method which can prevent and cure the adelphocoris suturails and the adelphocoris taeniophorus by using butyric acid hexylester which is the main ingredients of artificially synthesized sex pheromone of the adelphocoris suturails and the adelphocoris taeniophorus and interfering the transmission of mating information of male and female adelphocoris suturails and the adelphocoris taeniophorus. The method is suitable for the comprehensive prevention and cure of the domestic adelphocoris suturails. The mating rate can be reduced more than 80% after an isotropic agent device is provided. The isotropic agents of the method of using the sex pheromone isotropic agents to prevent and cure the adelphocoris suturails and the adelphocoris taeniophorus are strong in specificity, raw materials of a releasing device can be obtained easily and is easy to operate, influence of natural conditions is small, interference mating ability is strong and lasting period is long.

Description

technical field [0001] The invention belongs to the technical field of agricultural pest control, and in particular relates to a method for preventing and treating Lygus chinensis and Lygus three-spotted insects by using a sex pheromone misdirecting agent. Background technique [0002] Both Adelphocoris suturalis Jakovlev and Adelphocoris fasciaticollis Reuter belong to Hemiptera Hemiptera, Miridae Miridae, widely distributed from south to north in my country, and are an important pest in cotton production in my country. Its feeding habits are relatively mixed. In addition to cotton, its host plants include more than 80 species of plants such as Fabaceae, Amaranthaceae, Solanaceae, Compositae, etc., many of which are important vegetable and fruit crops in my country. Lygus meridianus and Lygus trispotata like to eat the meristems of plants, especially young leaves, flowers, and young fruits. After being sucked by them, a large number of holes are formed in the leaves, and de...
