Embodiment 1

[0031] (E)-β-ocimene and nerol are mixed with a ratio of 3:1 by volume to prepare a composition (composite attractant composition) for attracting Braconidus red-necked.

[0032] The composition is added to liquid paraffin oil to prepare the attractant of Braconidia erythrae, and the volume ratio of the composition to the liquid paraffin oil is 1:10.

Embodiment 2

[0034] (E)-β-ocimene and nerol are mixed with a ratio of 5:1 by volume to prepare a composition (composite attractant composition) for attracting Braconidus red-necked.

[0035] The composition is added to liquid paraffin oil to prepare the attractant of Braconidia erythrae, and the volume ratio of the composition to the liquid paraffin oil is 1:10.

[0036] Draw 1.0mL of the attractant and place it in a polyethylene slow-release vial (lure) and seal it to make a slow-release device.

Embodiment 3

[0038] After diluting the composition ((E)-beta-ocimene and nerol at a volume ratio of 5:1) prepared in Example 2 for attracting Braconids red-necked wasps with liquid paraffin oil at a volume ratio of 1:25 (that is, adding the composition to liquid paraffin oil and mixing evenly) to prepare the attractant of Brachydontia red-necked, draw 1.0 mL, put it in a polyethylene slow-release vial (lure) and seal it, and make a slow-release device.

Abstract

The invention relates to the technical field of biological control, and particularly discloses a composition and attractant for attracting Peristenus spretus as well as preparation and application ofthe composition and attractant. The invention discloses a composition for luring Peristenus spretus, which comprises (E)-beta-ocimene and nerol, and the volume ratio of the (E)-beta-ocimene to the nerol is (3-5): 1. The invention also discloses a Peristenus spretus attractant which comprises the composition for attracting Peristenus spretus and a sustained release agent, and the volume ratio of the composition to the sustained release agent is 1: (10-50). The invention further discloses a preparation method of the Peristenus spretus attractant and application of the Peristenus spretus attractant in conservation. According to the method, the cost is reduced, and meanwhile, the luring and conservation effects on the natural enemy parasitic wasp, namely the Peristenus spretus, of apolygus lucorum are improved.

Description

technical field [0001] The invention relates to the technical field of biological control. Specifically, it relates to a composition, an attractant, and its preparation and application for attracting Braconidus red-necked. Background technique [0002] The green ligus bug, Apolygus lucorum, is an important pest on a variety of commercial crops such as cotton, dates and grapes. In the Yangtze River Basin and the Yellow River Basin, as well as in the inland cotton areas of Northwest China, the degree of damage has increased year by year. Both adults and nymphs of the green Lygus can pierce and suck the terminal buds, young leaves, buds and flowers, fruits (or cotton bolls) and other tissues of harmful host plants, causing broken leaves, clusters of side branches, young buds falling off or shrinking, flowers and fruits Hazardous symptoms such as deformation. It has a huge impact on crop yield and quality, causing huge economic losses. Traditional chemical control will cause...
