Embodiment 1

[0013] The screening process of the attractant of the present invention is as follows: figure 1 shown.

[0014] 1. Determination of host plant volatile components

[0015] Rice leaf roller has a wide range of hosts, including rice, corn, sugarcane, wheat, sorghum and other grass crops and some grass weeds, and rice is the most suitable host. Volatile secondary substances in rice plants have obvious effects on the behavior of the rice leaf roller. By consulting a large number of literatures, we selected 42 kinds of plant volatile components (including 23 kinds of aliphatic compounds, 4 kinds of aromatic compounds, 10 kinds of monoterpenoids and 5 kinds of sesquiterpenoids) for research. These volatile substances mainly come from grasses such as rice, corn, and wheat (see Table 1 for details).

Abstract

The invention belongs to the technical field of biology, and particularly relates to an insect attractant and an application of the insect attractant. The attractant comprises trans-2-hexenal and a rice leaf roller sex pheromone at a ratio of (100-1000) micrograms:1 microgram. With the adoption of the composite attractant, an electroantennogram (EAG) reaction of rice leaf roller female and male moths to the sex pheromone can be remarkably reinforced; the quantity of the rice leaf roller female moths that reach an information source is increased; an effect of attracting the rice leaf roller female and male moths is achieved; and the attractant can be used for integrated control of rice leaf rollers.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to an insect attractant and its application, in particular to a compound attractant for attracting the female and male moths of the rice leaf roller, and to the application of the attractant. Background technique [0002] The rice leaf roller Cnaphalocrocis medinalis Güenée is a migratory pest that often occurs on rice in my country and poses a serious threat to rice production. The larvae of this insect eat and damage young leaves or flag leaves at the tillering stage or booting-heading stage of rice. Although they have a strong compensatory ability to damage rice at the splitting stage, they will still cause greater losses in the late growth period of rice. [0003] In production, the control of rice leaf roller mainly relies on chemical insecticides. Since the early 1980s, farmers have mainly used methamidophos to control rice leaf roller. Since methamidophos is a highly ...
