Abstract

The invention discloses a determination method and application of a volatile active compound with a repelling effect on dichocrocis punctiferalis, and the method comprises the following steps: step 1,respectively collecting sunflower disc volatile matters in a flowering period and a mature period by using a headspace dynamic gas sampling method, and analyzing the collected volatile matters by using a gas chromatograph-mass spectrometer, respectively identifying the types of sunflower disc volatiles in two periods; 2, comparing and analyzing sunflower disc volatile matters in a flowering period and a mature period, and selecting 12 volatile compounds which are respectively unique in the two periods and have large content change between the two periods to carry out a dichocrocis punctiferalis mated female moth behavior reaction test; and 3, testing the behavior reaction of the mated female moths of the dichocrocis punctiferalis to the selected 12 compounds by using a Y-shaped olfactometer, and determining that the [beta]-phellandrene can be used as a repellent of the dichocrocis punctiferalis when the concentration is 0.01 (v/V). According to the method, the volatile active compoundwith the repelling effect on the dichocrocis punctiferalis is accurately determined.

Description

technical field [0001] The invention relates to a botanical repellent, in particular to a method for determining and application of a volatile active compound capable of repelling the peach moth borer. Background technique [0002] The peach borer (Conogethes punctiferalis Guenée) belongs to the Lepidoptera and the Molinidae. It is an important and difficult-to-control borer pest that eats chestnuts, peaches, sunflowers and other fruits with its larvae. In recent years, with the adjustment of my country's agricultural industrial structure, the harm of peach borer has become increasingly serious. For example, in the summer corn producing areas of Huanghuaihai and Southwest Mountains, the population of the peach borer on the ear of corn increased rapidly, causing its damage degree to exceed that of the Asian corn borer (Ostrinia furnacalis), becoming the main pest of the local summer corn ear stage. Moreover, the prevention and control of the peach borer mainly relies on chem...
