Problems solved by technology

[0006] So far, great progress has been made in the research and application of plant volatile semiochemicals, but the use of active chemical components to develop attractants for the control of the two-spotted tarsus tarsus has not yet been reported. Tarsus firefly beetle damages economic crops, causing large-scale yield reduction and quality and quality decline

Embodiment 1

[0031] (1) Preparation of attractant (volume parts)

[0032] Take 0.5 part of 1-heptene, 1.5 part of citronene and 0.5 part of trans-2-hexenal and then mix them uniformly;

[0033] (2) with polyethylene slow-release bottle as slow-release carrier, and paraffin oil as solvent, carry out constant volume to obtain double-spotted long tarsus leaf beetle adult attractant lure core;

[0034] (3) The new moth trap is used as the trap, which can be directly purchased from Beijing Zhongjie Sifang Biotechnology Co., Ltd. When the trap is placed in the field, insert the end with the support tip into the soil, and adjust it according to the crop. The height of the trap, in the cotton field, is placed according to the height of the cotton plant. Generally, the bottom of the cone is about 0.55m away from the ground, so that the bottom of the trap is placed above the plant, and the slow-release lure of the attractant is fixed with one end of the wire, and the other end. Hang it on the edge ...

Embodiment 2

[0038] (1) Preparation of attractant (volume parts)

[0039] Take 1.5 parts of α-farnesene, 0.5 part of leaf alcohol and 0.5 part of trans-2-hexen-1-ol and mix them uniformly;

[0040](2) with polyethylene slow-release bottle as slow-release carrier, and paraffin oil as solvent, carry out constant volume to obtain double-spotted long tarsus leaf beetle adult attractant lure core;

[0041] (3) The sticky insect board is used as the trap, which can be directly purchased from Beijing Zhongjie Sifang Biotechnology Co., Ltd. When the trap is placed in the field, the slow-release attractant core and one end of the support rod are fixed with iron wire. Insert the other end of the support rod into the soil, adjust the height of the trap according to the crop, in the cotton field, place it according to the height of the cotton plant, generally the sticky board is about 0.55m away from the ground, so that the bottom end of the sticky board is placed above the plant, adjust The position...

Embodiment 3

[0045] (1) Preparation of attractant (volume parts)

[0046] Take 0.5 part of α-phellandrene, 0.5 part of β-pinene and 1.5 part of nerolidol and mix them evenly;

[0047] (2) with polyethylene slow-release bottle as slow-release carrier, and paraffin oil as solvent, carry out constant volume to obtain double-spotted long tarsus leaf beetle adult attractant lure core;

[0048] (3) The new moth trap is used in conjunction with the sticky board as a trap. The trap and sticky board can be purchased directly from Beijing Zhongjie Sifang Biotechnology Co., Ltd. When the trap is placed in the field, there will be Insert one end of the support tip into the soil, fix the attractant slow-release lure core with iron wire at one end, and hang the other end on the edge of the hole at the upper end of the trap cone, adjust the height of the trap according to the crop, and place it according to the height of the cotton plant, generally a trap The height of the bottom end is set at about 0.5...

Abstract

The invention belongs to the technical field of biological control of field pests, and discloses an adult attractant for the two-spotted firefly beetle. Orangene, trans-2-hexenal, α-farnesene, trans-2-hexen-1-ol, leaf alcohol, α-phellandrene, β-pinene, nerolidol; one of the above The adult attractant of the two-spotted beetle beetle is reasonable in proportion, the attractant effect is remarkable, and it has the advantages of being green, safe, effective, and long-lasting. Crops are of great significance and can be widely used in actual production of farmland and urban green belts.

Description

technical field [0001] The invention belongs to the technical field of biological control of field pests, relates to the method of trapping field pests by combining semiochemicals with traps, and in particular relates to an adult attractant for the double-spotted tarsus beetle. Background technique [0002] Monolepta hieroglyphica (Motschulsky) belongs to Coleoptera, Chrysomelidae, subfamily Galerucinae, alias double-spotted firefly, is a kind of main damage cotton, corn and some cruciferous vegetables and other varieties It is a worldwide pest of crops, mainly distributed in Russia (Siberia), North Korea, Japan, India, the Philippines and other countries and regions, and is distributed in most parts of my country. [0003] The way of harm is mainly to eat the epidermis and mesophyll of the upper leaves with the chewing mouthparts of the adults to form mosaic leaves. When the damage is serious, it will cause nicks and holes in the leaves, which will seriously affect the phot...
