Embodiment 1

[0021] (cis 8)-dodecene-1-acetate, (trans 8)-dodecene-1-acetate, (cis 8)-dodecen-1-ol, (trans 8 , trans 10)-dodecadien-1-ol, the weight composition ratio of dodecyl-1-ol and tetradecyl-1-ol is mixed according to 20:8:10:35:15:5, and n-hexyl Alkanes dubbed sex pheromone solution. Wherein, the weight composition ratio of pheromone component to n-hexane is 1:50. Then, the natural rubber reversing plug is soaked in the sex pheromone solution overnight, and then dried to obtain the lure of the small pear borer (ie, the six-component lure). In a mixed orchard of 5 acres of peaches and pears, five sets of boat traps (each with a lure) were randomly placed, and the number of males of the small pear borer worm was observed and recorded every day at 8 o'clock in the morning. Statistics are in Table 1.

Embodiment 2

[0028] Other conditions are the same as in Example 1, the pheromone active ingredient is changed to (cis 8)-dodecene-1-acetate, (trans 8)-dodecene-1-acetate, (cis 8) -dodecen-1-ol and dodecen-1-ol, the weight composition ratio of the four components is 70:8:22:4, namely to obtain the four-component lure of pear borer as control 1. Statistics are in Table 1.

Embodiment 3

[0030] Other conditions are the same as in Example 1, the pheromone active ingredient is changed into (cis 8)-dodecene-1-acetate and (trans 8)-dodecene-1-acetate, the two components The weight composition ratio is 90:10, that is, the two-component lure of pear borer is obtained, which is used as control 2. Statistics are in Table 1.

Abstract

The invention relates to a sex attractant for fruit tree pest Grapholitha molesta Busck and belongs to the technical field of control on the fruit tree pest Grapholitha molesta Busck. Effective ingredients of sex pheromones of the Grapholitha molesta Busck comprise (Z8)-dodecen-1-acetate, (E8)-dodecen-1-acetate, (Z8)-dodecen-1-ol, (E8, E10)-dodecadien-1-ol, dodeca-1-ol and tetradeca-1-ol, the ingredients of the sex pheromones are mixed with a sustained release solution to form a sex pheromone solution, the sex pheromone solution is added to a release carrier, and a lure and an isotropic tube can be obtained. When the sex attractant is applied to peach orchards and pear orchards, the lure has very strong trapping effect on the Grapholitha molesta Busck, the isotropic tube can significantly interfere with mating activities of female Grapholitha molesta Busck and male Grapholitha molesta Busck, the sex attractant is used for controlling the fruit tree pest Grapholitha molesta Busck and shows the excellent control effect, and the pest-damaged fruit rate of the orchards is greatly reduced.

Description

Technical field: [0001] The invention relates to a sexual attractant for the fruit tree pest pear borer, and belongs to the technical field of prevention and control of the fruit tree pest pear borer. Background technique: [0002] The English scientific name of the small pear borer Grapholitha molesta Busck, referred to as pear small, also known as the oriental fruit beetle, belongs to Lepidoptera Lepidopteridae. In recent years, the small pear borer has become the main pest that endangers the main pear and peach producing areas in my country. Pear borer has many generations and complex life history. It has 5 generations a year in the south of the Yangtze River and 4 generations a year in other areas. Overwintering larvae begin to pupate and emerge in mid-to-late March of the second spring, and mid-to-late August is the period that causes the most damage to pome fruit and late peaches. The fourth-generation adults appeared from early August to early September, but the pop...
