preparation example Construction

[0028] The preparation method of trapping agent: promptly obtain trapping agent after each component in embodiment 1 to embodiment 5 is mixed; According to the consumption of each lure core 1 gram, attractant is directly added dropwise on respectively corresponding lure core by dosage, puts into the release device. Add 1-10 g of the attractant in Examples 6 to 9 into 1 g of paraffin oil respectively to prepare an attractant solution; wherein the amount of attractant in Examples 6 to 9 is 1 gram, 3 grams, 5 grams respectively and 10 grams.

[0029] Drop the dose of 1 gram on each lure on the respective lure, and put it into the corresponding slow-release device.

[0030] The above-mentioned slow-release device is a ventilated container, and a plastic bottle can be used, and holes are punched on the plastic bottle to allow the smell in it to be released slowly.

Embodiment 1 to 9

[0031] Bioassays were performed on Examples 1 to 9:

[0032] 1) Mesh cage experiment:

[0033] In the cage of 11m×11m×2m, traps equipped with traps (respectively 5ml) were suspended according to the Latin square design, and the interval between adjacent traps was 1m, and a blank group was used as a control.

[0034] In the center of the net cage, 200 pairs of fruit fly adults were released at the same height as the trap, and the ratio of male to female was 1:1. The number of fruit flies in each trap was counted 8 hours after the insects were released. The test time is from 9:00 to 17:00 every day. The position of each trap was randomly moved every 2h to reduce the influence of the position of the trap. The trapping experiment was repeated 5 times.

[0035] 2) Field trapping experiment

[0036] During the ripening season of red bayberry, hang traps on the bayberry mountain. The traps are hung on the fruit trees about 1.5m above the ground, and the distance between adjacent...

Abstract

The invention relates to an attractant for male and female fruit flies and melon flies. The attractant is characterized in that the attractant is fructone and / or butyric acid isoamylester. Preferably, the attractant is mixture of fructone and butyric acid isoamylester in a weight ratio of 1-2: 1. That the chemical pheromone attractants for fruit flies and melon flies are butyric acid isoamylester and fructone is discovered and identified for the first time; and a dosage of 0.1 to 10 g of the attractant exerts trapping and killing effects on male and female fruit flies and melon flies, and the amount of trapped female imagoes is higher than the amount of trapped male imagoes. Thus, the attractant is of greater significance to forecasting and control.

Description

technical field [0001] The invention relates to an attractant for male and female fruit flies and fruit flies. Background technique [0002] Due to the lax law enforcement of plant quarantine in our country, some foreign fruit flies quickly entered our country. In addition, in the past 10 years, the planting area and varieties of fruits and vegetables have developed rapidly. The harm of melon fly etc. expands rapidly and increases the weight of. Fruit flies have become a particularly serious pest of fruits and some vegetables in southern my country. In some areas, fruit flies have caused devastating losses to local fruit and vegetable production. [0003] Fruit fly damage has the following characteristics. 1) The damage is serious and difficult to control; 2) The generation period is short and the reproduction speed is fast; 3) The pests have strong resistance to pesticides; 4) The pests are exclusively harmful to mature fruits, and the damage is serious at the stage when ...
