Problems solved by technology

However, the trapping amount of this mixture is far less than the trapping amount of the sex pheromone of the pear borer moth
[0005] The synergistic effect of these two compounds on improving the sex pheromones of pear borer worms alone or in combination has not been reported

Embodiment 1

[0052] A synergist for sex pheromone of pear borer moth, the synergist is composed of β-ocimene, (E)-β-farnesene and 2,6-di-tert-butyl-4- Composition of methyl phenol; the three compounds of β-ocimene, (E)-β-farnesene and 2,6-di-tert-butyl-4-methylphenol are mixed according to the above mass ratio, and the preparation is prepared by a peristaltic pump The solution pumps of the three compounds are added into polyvinyl chloride tubes with an inner diameter of 0.8 mm and an outer diameter of 1 mm; then, the filled polyvinyl chloride tubes are sealed and cut at intervals of 3-5 cm with a pliers-type sealing machine; Place the cut polyvinyl chloride tube in the refrigerator for later use.

[0053] Adopt field trapping test, when carrying out test, adopt pear small borer moth lure (produced by Institute of Animals, Beijing Chinese Academy of Sciences) and synergistic formula to combine, be placed in triangular trap, 2cm away from sticky insect plate below trap. At the same time, a ...

Embodiment 2

[0055] A synergist for sex pheromone of pear borer moth, the synergist is composed of β-ocimene, (E)-β-farnesene and 2,6-di-tert-butyl-4- Composition of methyl phenol; the three compounds of β-ocimene, (E)-β-farnesene and 2,6-di-tert-butyl-4-methylphenol are mixed according to the above mass ratio, and the preparation is prepared by a peristaltic pump Pump the solution of the three compounds into a polyvinyl chloride tube with an inner diameter of 0.6 mm and an outer diameter of 0.8 mm; then use a clamp-type sealing machine to seal and cut the filled polyvinyl chloride tube every 3-5 cm ; Place the cut polyvinyl chloride tube in the refrigerator for later use.

[0056] Adopt field trapping test, when carrying out test, adopt pear small borer moth lure (produced by Institute of Animals, Beijing Chinese Academy of Sciences) and synergistic formula to combine, be placed in triangular trap, 2cm away from sticky insect plate below trap. The traps are 1.5m above the ground, and are...

Embodiment 3

[0058] A synergist for sex pheromone of pear borer moth, the synergist is composed of β-ocimene, (E)-β-farnesene and 2,6-di-tert-butyl-4- Composition of methyl phenol; the three compounds of β-ocimene, (E)-β-farnesene and 2,6-di-tert-butyl-4-methylphenol are mixed according to the above mass ratio, and the preparation is prepared by a peristaltic pump The solution pumps of the three compounds are pumped into polyethylene tubes with an inner diameter of 1 mm and an outer diameter of 1.2 mm; then, the filled polyethylene tubes are sealed and cut at intervals of 3-5 cm with a pliers-type sealing machine; The cut polyethylene tubes were placed in the refrigerator for later use.

Abstract

The invention discloses a synergist for preventing and controlling sex pheromone of pear borer moth and a preparation method thereof. The synergist is composed of β-ocimene, (E)-β-farnesene and 2,6 in the ratio of 1:0.2:0.05 ‑di-tert-butyl‑4‑methylphenol. Mix the three compounds of β-ocimene, (E)-β-farnesene and 2,6-di-tert-butyl-4-methylphenol according to the above mass ratio, and use a peristaltic pump to prepare the three compounds Add the solution into the polyvinyl chloride or polyethylene tube; then use the clamp sealer to seal the filled polyvinyl chloride or polyethylene tube every 3-5 cm and cut it; cut the polyvinyl chloride or polyethylene Store the tube in the refrigerator until ready to use. The invention has the advantages that it can greatly increase the trapping amount of the sex pheromone of the small pear borer in the field, prolong the slow release time of the sex pheromone of the small pear borer, and the compound is non-toxic, does not harm natural enemies and has no residue, which is beneficial to the protection of the ecological environment.

Description

technical field [0001] The invention belongs to the field of biological pesticide preparations, and in particular relates to a synergist for preventing and controlling sex pheromone of the pear borer moth and a preparation method thereof. Background technique [0002] Pear molesta [Grapholitha molesta (Busck)], also known as pear fruit moth or Oriental fruit beetle, is a common fruit-boring pest in orchards, which can damage peaches, pears, cherries and other fruit trees. The small pear borer has not been reported in my country except Tibet, but it occurs in all pear and peach producing areas, especially in North China and Central China. In recent years, in my country's peach pear producing areas, the damage of pear borer has become more and more serious, and it has risen to be the primary pest. At present, the control of pear borer in my country mainly relies on fruit bagging and chemical control. Due to the hidden way of the insect's damage, the requirements for the prop...
