Embodiment 1

[0022] like figure 1 As shown, the present embodiment adopts the method that the absorption tube 5 that contains Porapak-Q adsorbent or SPME extraction head extracts the volatile matter of citrus young green fruit (Hongjiang orange young fruit) is extracted, and adopts GC-EAD and GC-MS The components of the volatile matter are tested and identified. The volatile matter collection device includes placing the young Hongjiang orange fruit in the flavor source bottle 4, the top of the flavor source bottle 4 is connected to the adsorption tube 5, and Porapak-Q is placed in the adsorption tube 5. Adsorbent, the adsorption tube 5 is connected with the atmospheric sampler 6 through the connecting tube, and the bottom of the taste source bottle 4 is also connected with the flow meter 3, the activated carbon filter tube 2 and the air pump 1 through the connecting tube in sequence, and the air pump 1 is G-103 chromatographic The air pump is produced by Beijing Dongxi Analytical Instrumen...

Abstract

The invention provides a method for testing young-citrus-fruit-originated volatile matters having effects on adult Bactrocera minax. According to the results of the testing method, the young-citrus-fruit-originated volatile matters including limonene, 4-terpene alcohol, nonanal and citral have behavioral reaction effects on adult Bactrocera minax; limonene, 4-terpene alcohol and citral all have effects on male citrus Bactrocera minax; and limonene and nonanal both have effects on female citrus Bactrocera minax. It is confirmed for the first time that the young-citrus-fruit-originated volatilematters having effects on male and female adults of Bactrocera minax include limonene, 4-terpene alcohol, nonanal and citral, and the young-citrus-fruit-originated volatile matters can be further applied to research and development of attractants and repellents and play a positive role in pollution-free prevention and treatment in citrus production areas.

Description

technical field [0001] The invention belongs to the technical field of agricultural pest control, and in particular relates to a method for testing citrus young fruit volatiles that have behavioral responses to adults of Bactrocera citrus. Background technique [0002] Bactrocera citrus is a major pest in the citrus industry. It mainly harms Southeast Asia, including citrus producing areas in my country. It is a worldwide invasive and quarantine pest. Its control mainly relies on chemical pesticides. The use of pesticides for many years has caused serious pesticide residue problems, making China The export of citrus to developed countries such as Europe, America and Japan is restricted, and it is urgent to find new green and pollution-free pest control methods. The use of citrus plant volatiles to trap and kill citrus fruit flies is an ideal biological control method, but we know little about the citrus volatiles that citrus fruit flies can sense. In our research on citrus vo...
