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 ...

Abstract

The invention discloses a sex pheromone synergist for preventing and controlling Grapholitha molesta, and a preparation method thereof, wherein the synergist comprises beta-ocimene, (E)-beta-farneseneand 2,6-di-tert-butyl-4-methylphenol according to a ratio of 1:0.2:0.05. The preparation method comprises: mixing beta-ocimene, (E)-beta-farnesene and 2,6-di-tert-butyl-4-methylphenol according to the mass ratio, and adding the three prepared solutions to a polyvinyl chloride or polyethylene pipe by a peristaltic pump; sealing the filled polyvinyl chloride or polyethylene pipe every 3-5 cm by a clamp type sealing machine, and cutting; and placing the cut polyvinyl chloride or polyethylene pipe in a refrigerator so as to be used for spare. According to the present invention, the synergist cangreatly increase the trapping amount of the Grapholitha molesta sex pheromone in the field, can further prolong the sustained release time of the Grapholitha molesta sex pheromone, and further has characteristics of no toxicity, no harm to natural enemies, no residue and easy ecological environment protection.

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...
