Description

Citrus fruit fly attractant
Technical Field
The invention belongs to the technical field of insect attractants, and particularly relates to a citrus fruit fly attractant.
Background
The citrus fruit fly, also known as small fruit fly, oriental fruit fly, yellow fly, fruit maggot, etc., belongs to the diptera family of fruit fly, is a fatal pest in fruit and vegetable industries in southeast Asia and Pacific region, and is also a destructive pest in fruit production in south China. The insect is a parasitic insect, and adult insects like to lay eggs in the peel of carambola, guava, citrus, loquat, peach and other fruits in the color-changing period, and hatched larvae eat in the flesh of the fruits, so that the fruits are rotten and dropped, and the quality and the yield of the fruits are seriously influenced. The rapid propagation speed and the wide spread and diffusion range of the citrus fruit fly bring great obstacles to the control of the citrus fruit fly.
At present, the prevention and control means for citrus fruit flies mainly comprises spraying chemical pesticides, agricultural prevention and control and hanging attractant. Due to unreasonable use of chemical pesticides, citrus fruit fly field populations in some areas of China have generated serious drug resistance to pesticides such as organophosphorus insecticides, abamectin and beta-cypermethrin, and in addition, pesticide residues on fruits can harm human health; the agricultural prevention and control method is to cover the fruits in the plastic bags to prevent the fruits from insect damage, but the agricultural prevention and control method wastes time and labor, has high cost and poor economical efficiency; the method for trapping and killing citrus fruit flies is an environment-friendly and effective control means, the methyl eugenol attractant which is chemically synthesized is mainly used at present, but the price is high, the trapping effect is continuously weakened, and more importantly, the methyl eugenol can induce human beings to generate malignant tumors and cause harm to the human beings.
Therefore, Chinese patent document CN105815344A discloses a compound attractant for bactrocera dorsalis, which is composed of a thousand layers of gold essential oil, lemon essential oil and 25 wt.% of peptone solution, wherein the volume weight ratio of the thousand layers of gold essential oil, the lemon essential oil and the 25 wt.% of peptone solution is 1:1:2, and the thousand layers of gold essential oil and the lemon essential oil in the attractant can cause the bactrocera dorsalis to be influenced by odor at a far position so as to attract the bactrocera dorsalis; in addition, the thousand-layer gold essential oil, the lemon essential oil and the peptone are all derived from animals and plants, and the raw materials are easily available in actual production, so that the environment protection is facilitated. However, the main component of the Huperzia serrata essential oil in the technology is methyl eugenol, and the methyl eugenol causes drug resistance of the bactrocera dorsalis after long-term use, so that the attractant effect of the attractant on the bactrocera dorsalis is reduced, and the methyl eugenol has hidden danger on human health; secondly, the peptone solution is inconvenient to store and use, needs to be prepared and used at the moment, is difficult to produce in a large scale to form a mature product for popularization and sale, and has limited practicability. Therefore, it is of great significance to improve the existing citrus fruit fly attractant to overcome the defects.
