Fruit fly trapping agent containing grape terpenoids, and application thereof

Abstract

The invention discloses a fruit fly trapping agent containing grape terpenoids, and an application thereof, and belongs to the technical field of agricultural science. The fruit fly trapping agent containing grape terpenoids comprises a basal culture medium and an attractant. 100 parts of the basal culture medium comprise, by weight, 5-10 parts of corn flour, 0.5-2 parts of agar, 5-10 parts of sucrose, 1-2 parts of yeast powder, 0.5-1 part of propionic acid, and the balance of distilled water; and the attractant is one of four terpene volatile substances, namely linalool, geraniol, citral andgeranic acid, extracted from grape fruits. The fruit fly trapping agent has an obvious fruit fly trapping effect, and can be combined with other fly killing devices to effectively trap and kill fieldfruit flies and reduce the use amounts of pesticides, and so a basis is provided for developing the novel, efficient, green and safe fruit fly trapping agent.

Description

technical field [0001] The invention relates to the field of agricultural science and technology, in particular to a fruit fly trap containing grape terpenoids and an application thereof. Background technique [0002] Drosophila belongs to Diptera and Tephritidae. It has a wide range of hosts and strong reproductive ability. It harms a variety of fruits and vegetables. It is widely distributed and mainly feeds on rotten fruits. Adults have a tendency to sweet and yellow fruits. Lay eggs under the fruit skin. After hatching, the larvae absorb the nutrients of the fruit. After the larvae mature, they emerge from the damaged area to pupate. After the pupae emerge into adults, they mate and lay eggs. There are hundreds of them, and they can become adults in 1 to 2 days under a suitable growth environment. They mainly harm a variety of fruits such as bayberry, grapes, blueberries, cherries, peaches, etc., as well as melons and vegetables such as loofah and cucumber. [0003] Fru...

AI Technical Summary

Problems solved by technology

[0003] Fruit flies are particularly harmful to berries such as grapes, blueberries, and cherries, causing huge economic losses. The fruit that has been laid eggs has no obvious symptoms of damage in a short period of time, but as the eggs hatch into larvae, the surface of the damaged fruit will appear rotten Sunken, slightly darker and duller than normal fruit surface

If the fresh fruit is soaked in water, the larvae will crawl out from the damaged part and float in the water, causing a psychological shadow for consumers. In addition, the wounds of the damaged fruit are easily infected with pathogenic bacteria, rot and deteriorate, lose their edible value, and affect the quality of the fruit and marketing

[0004] At present, the control methods of fruit flies include agricultural control and chemical control. Agricultural control includes: 1. Timely removal of insect fruit, rotten fruit, and fallen fruit in the orchard, centralized treatment or burial, elimination of larvae in the fruit, and reduction of the number of adults in the next generation. The method has high labor costs and poor practicality; 2. Hanging yellow insecticidal boards for trapping, because fruit flies have a certain tendency to yellow, hanging yellow trapping boards in the orchard can trap adults and effectively reduce the amount of eggs laid, but the trapping effect Limited, it needs to be used with insect traps or fruit fly traps, but most of the insect traps on the market are not effective. In addition to agricultural control methods, chemical control measures, such as spraying pyrithione, cypermethrin insecticides, Lushi and Guoruite decoy insecticides are also common ways to kill insects. However, due to side effects such as pesticide residues, environmental pollution, and food safety caused by chemical insecticides, the acceptance of chemical insecticides by consumers is low. Therefore, it is of great significance to research and develop safe and efficient ways of killing insects.
