Botanical mollusk attractant and lure and preparation method thereof

Abstract

The invention discloses a botanical mollusk attractant and a lure and a preparation method thereof, and belongs to the technical field of attractants, the botanical mollusk attractant comprises a plant extract and an auxiliary component, and the lure is prepared from the attractant and agarose gel. Wherein the plant extract is an extract of tobacco seedling leaf tissues, cabbages or lettuces. The mollusks such as slugs and snails which are harmful to the field can be effectively trapped in combination with a trap, and a new method is provided for mollusk prevention and control.

Description

technical field

[0001] The invention belongs to the technical field of attractants, and in particular relates to a plant-derived mollusk attractant, a lure core and a preparation method thereof. Background technique

[0002] Molluscs such as slugs and snails have caused great harm to cabbage, lettuce and other vegetables and tobacco cultivation in many countries and regions in the Americas and Asia. In addition, molluscs such as slugs and snails are intermediate hosts of some parasites, threatening social health and safety. The chemical pesticides used to control molluscs such as slugs and snails are mainly metaldehyde, carbaryl or the combination of the two, but these pesticides cause great environmental hazards. Therefore, there is an urgent need for a green and safe control method to prevent and control molluscs such as field slugs and snails. Attractants have been widely used in the control of agricultural pests. They are a new type of green and efficient control metho...

[0023] Adopt above-mentioned raw material that provides, carry out the preparation of the plant source lure core of mollusk, its preparation method comprises the following steps:

[0024] ① Prepare 10ml of 1%-1.5% agarose gel: weigh 0.1-0.5g of agar powder and pour it into 10-50ml of pure water, boil the mixture until it is colorless and transparent;

[0025] ② Add 1.5-2ml of attractant to the hot solution prepared in ①, shake for 10-30 seconds, pour the solution into a 50ml centrifuge tube, and get the lure after cooling.

[0027] The attractant is prepared by mixing plant volatiles and purified water.

[0028] Prepare lures according to the following steps:

[0029] ① First prepare the attractant, fully grind 1 part of tobacco leaf tissue, add 6 parts of pure water, centrifuge at 3000-4000r / min for 1-2min, and take the supernatant to obtain the attractant;

[0030] ② Prepare 10ml of 1%-1.5% agarose gel: Weigh 0.5g of agar powder and pour it into 20ml of pure water, boil the mixture until it is colorless and transparent;

[0031] ③ Add 2 ml of attractant mixture to the hot solution prepared in ②, shake for 30 seconds, pour the solution into a 50 ml centrifuge tube, and get the lure after cooling.
