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) Prepare attractant (parts by volume)

[0032] Take 0.5 parts of 1-heptene, 1.5 parts of orangerene and 0.5 parts of trans-2-hexenal and mix them uniformly;

[0033] (2) take the polyethylene slow-release bottle as the slow-release carrier, paraffin oil as the solvent, carry out constant volume and promptly make the lure core of the adult attractant of the two-spotted firefly beetle;

[0034] (3) Use a new type of moth trap as a trap, which can be purchased directly from Beijing Zhongjie Sifang Biotechnology Co., Ltd. When the trap is placed in the field, insert the end with the support point into the soil, adjust according to the crop The height of the trap is placed according to the height of the cotton plant in the cotton field. 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 at one end with an iron wire. Hang on the edge of the ho...

Embodiment 2

[0038] (1) Prepare attractant (parts by volume)

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

[0040](2) take the polyethylene slow-release bottle as the slow-release carrier, paraffin oil as the solvent, carry out constant volume and promptly make the lure core of the adult attractant of the two-spotted firefly beetle;

[0041] (3) Use a sticky insect trap as a trap, which can be purchased directly from Beijing Zhongjie Sifang Biotechnology Co., Ltd. When the trap is placed in the field, fix the attractant slow-release lure core and one end of the support rod with an iron wire. Insert the other end of the support rod into the soil, and 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 of the sticky board is placed above the plant and adj...

Embodiment 3

[0045] (1) Prepare attractant (parts by volume)

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

[0047] (2) take the polyethylene slow-release bottle as the slow-release carrier, paraffin oil as the solvent, carry out constant volume and promptly make the lure core of the adult attractant of the two-spotted firefly beetle;

[0048] (3) A new type of moth trap is used in conjunction with the sticky board as a trap. Both the trap and the sticky board can be purchased directly from Beijing Zhongjie Sifang Biotechnology Co., Ltd. When the trap is placed in the field, there will be One end of the support tip is inserted into the soil, one end of the attractant slow-release lure core is fixed with an iron wire, and the other end is hung on the edge of the hole at the upper end of the trap cone, the height of the trap is adjusted according to the crop, and the height of the cotton plant is placed, generally a trap ...

Abstract

The invention belongs to the technical field of biological prevention and control of field pests, and discloses an attractant for adults of monolepta hieroglyphica. The active components of the attractant is composed of a host plant volatile matter of the adults of monolepta hieroglyphica. The host plant volatile matter is prepared from 1-heptene, orange alkene, trans-2-hexenal, alpha-farnesene, trans-2-hexene-1-ol, leaf alcohol, alpha-phellandrene, beta-pinene and nerolidol; The attractant is reasonable in proportion and remarkable in attraction effect, has the advantages of being green, safe, effective, long in lasting period and the like, has important significance on protection of field crops such as cotton and corn which are damaged by the monolepta hieroglyphica, and can be widely applied to actually-produced farmlands and urban green belts.

Description

technical field [0001] The invention belongs to the technical field of biological control of field pests, and relates to the method of trapping semiochemicals combined with traps to prevent and control field pests, in particular to an adult attractant for the two-spotted long tarsus beetle. Background technique [0002] Monolepta hieroglyphica (Motschulsky) belongs to the Coleoptera order Coleoptera, Chrysomelidae Chrysomelidae, subfamily Galerucinae, also known as the double-spotted firefly leaf beetle. It is a species that mainly damages cotton, corn and some cruciferous vegetables. A worldwide pest of crops, mainly distributed in Russia (Siberia), North Korea, Japan, India, the Philippines and other countries and regions, and distributed in most parts of my country. [0003] The way of damage is mainly through the chewing mouthparts of adults to feed on the epidermis and mesophyll of upper leaves to form mosaic leaves. When the damage is serious, it will cause nicks and h...
