Embodiment 1

[0017] A kind of preparation method of pollinator insect or natural enemy insect attractant

[0018] More than one of anisyl alcohol, anisaldehyde or its derivative 1-(4-methoxyphenyl)-5-(β-ionone ring)-1,4-dien-3-one Dissolve in dichloromethane, take the solution and add it to the rubber carrier (each rubber carrier contains 2-100mg of drug), prepare the lure, and add clean dichloromethane after the solvent evaporates, so that the drug ingredients can fully penetrate into the rubber. After the solvent evaporates again, wrap the attractant lure with tinfoil, put it in a ziplock bag and store it in a -4°C refrigerator for later use.

[0020] Experiments on Attractive Effects of Pollinating Insects or Natural Enemy Insect Attractants

[0021] From September 25, 2013 to October 5, 2013, the experiment of attracting pollinators or natural enemies was carried out in the cotton field of Langfang Base, Hebei Province (adjacent to the plot of flowering plants). A cotton field with consistent growth, consistent management conditions, and large and neat plots was selected as the experimental field. To facilitate detection of the lure effect, the lure core prepared in Example 1 is placed on the barrel trap, and the middle part of the barrel trap is placed flush with the top of the crop, and the distance between adjacent traps is 10m. Four replicates were set up for each treatment, arranged randomly, and a rubber carrier permeated with clean methylene chloride was used as a control. After setting, investigate the types and quantities of pollinator insects or natural enemy insects attracted every two days. The result...

Abstract

The invention discloses an attractant for one class of pollination insects or natural enemy insects, belonging to the technical field of the preparation of insect attractants. The attractant comprises active compositions including anisyl alcohol, anisic aldehyde or derivatives, and the structural formulas of the active compositions are shown as formulas I, II and III. The invention further provides a use method of the attractant for the pollination insects or the natural enemy insects under the action of attraction, and the attractant for the pollination insects or the natural enemy insects, disclosed by the invention, can effectively attract the pollination insects and the natural enemy insects for insect-pollination crop, and is simple in use method, cheap, innoxious for human and livestock, and environmental-friendly.

Description

technical field [0001] The invention belongs to the technical field of insect attractant preparation, and in particular relates to a class of attractant for pollinator insects or natural enemy insects. Background technique [0002] Nearly 80% of angiosperms in nature are entomophilous plants, and these plants must rely on insect pollination to complete pollination, fruiting and reproduction. Insect pollination can make plants have the opportunity to fully select fertilization, improve hybrid vigor, improve seed setting and seed yield and quality, and can increase the viability of plants. At the same time, insect pollination plays an important role in beautifying the environment and maintaining the natural ecological balance. The use of pollinators to promote the development of agriculture and forestry is an advanced bio-agricultural technology that is environmentally friendly, energy-saving and convenient, and can realize the rational development and utilization of natural ...
