Repellent for pine wood nematode propagation vector insects

Abstract

The invention discloses a repellent for pine wood nematode propagation vector insects. The repellent is prepared from the following components in percentage by weight: 5% to 26% of active component, 13% to 26% of synergistic component, 4% to 13% of stabilizer, and 43% to 78% of solvent, wherein the sum of the percentages of the components by weight is 100%; the active component is a mixture of linalool, limonene, cineole, methyl salicylate, rosolic acid, ocimene, isoborneol, trans-caryophyllene, methyl charvicol, methyl salicylate, and verbena oil; the synergistic component comprises one or more than one of dipentene, cyclohexylamine, oxalic acid, guaiacol and alpha-phellandrene; the stabilizer comprises one or two of methyl carbonate, ethylene glycol, BHT and polyisobutylene. The repellent has the advantages that the food taking and egg laying of adult vector insects with the pine wood nematode propagation function can be effectively repelled, and the pine wood nematode propagation probability of the vector insects is reduced.

Description

technical field [0001] The invention relates to a repellent, in particular to a repellent for the vector insect of pine xylophilus. Background technique [0002] Pine wood nematode is the pathogen of pine wood nematode disease, which naturally spreads into healthy pine trees through the wounds of vector insects such as monochamus and monochamus alternatus, causing the pine trees to wilt and die. [0003] The short-distance transmission of pine xylophilus is mainly carried out by the vector insects. At present, the prevention and control of the vector insects is mainly carried out by hanging traps, setting lures or chemical pesticides in the forest stands, aiming to reduce the forest The population density of the vector insects, but the vector insects can fly and spread, the junction of the non-occurrence area and the occurrence area of ​​pine xylophilus, the prevention of pine forests and ancient and famous trees at the junction of forest stands and healthy forest stands in ...
