Problems solved by technology

This method has the following disadvantages: one is that the amount of methyl eugenol used is too large, which causes a lot of waste and increases the cost of prevention and control; The consumption of eugenol is too fast, and the use time of the lure is short. Third, the use of methyl eugenol alone can only trap and kill male insects but cannot trap and kill female insects.

Embodiment 1

[0023] Each treatment was formulated into mixed solution A, B, C, D according to the ratio shown in Table 1, and the control was E, F, G. Add insecticides with a content of no more than 0.5% to each prepared treatment, and then take 2 milliliters of each mixed solution and drop them into cotton cores to make lures. Traps are made from mineral water bottles. Open an opening with a diameter of 2.4 to 3 centimeters on both sides corresponding to the wall of the mineral water bottle, for the purpose of smell emission and insect entry. The distance between the two openings is about 3 to 5 cm. The volume of the trap is about 600 ml. Hang the trap in the orchard. The trap is about 1.5 meters above the ground. Each trap is 30-50 meters apart. 3 replicates per treatment. The experiment was observed continuously for 20 days. The test results are shown in Table 2.

Embodiment 2

[0031] Preparation of sweet and sour alcohol mixture Sugar, wine, vinegar and water are prepared as shown in Table 3.

[0032] Preparation of methyl eugenol lure core Add to the rubber core after dissolving methyl eugenol with dichloromethane. The lures with different contents are prepared respectively. Store the prepared lure in the refrigerator for later use.

[0033] When carrying out the Bactrocera dorsalis trapping experiment in the field, the trap is made of a plastic bottle (600ml in volume, 6cm in diameter), and two stomata with a diameter of about 2.4 to 3 centimeters are respectively opened on the side wall for odor emission and insect entry. Put the sweet and sour alcohol solution at the bottom of the bottle, and add a little insecticide to the mixture. The lure core is suspended with thin iron wire at about 0.1 to 0.5 cm above the liquid level of the sweet and sour alcohol mixture. Each trap is 20-30m apart. Using the above method, the trapping effect of differ...

Abstract

The invention relates to two kinds of Bactrocera dorsalis imago attractant that is made up from 1-20wt% methyleugenol, 4-20wt% sugar, 10-30wt% alcohol, 10-30wt% vinegar, 30-75wt% water. The attractant has good effect to Bactrocera dorsalis and male adult, especially the male adult. The invention is low cost, easy to operate, and has good persistence.

Description

technical field [0001] The invention relates to an attractant for Bactrocera dorsalis and belongs to the field of pest control. Background technique [0002] Bactrocera dorsalis is an important pest distributed in South China and Southwest China. It belongs to the second-class quarantine pest. It can damage more than 200 kinds of crops such as mango, pomegranate, citrus, peach, plum, pepper, tomato, and cucumber. [0003] The growth and development of Bactrocera dorsalis are characterized by strong flying ability, long life span and high reproductive rate of adults. Adult Bactrocera dorsalis can fly forty kilometers or more. When the temperature is around 26°C, the lifespan of adults can reach 90-120 days, and the number of eggs laid by females ranges from 200-400. Under natural conditions, the larvae of Bactrocera dorsalis eat in the fruit, mature and pupate in the soil. [0004] Bacteralis dorsalis mainly damages the mature fruit of the host plant. There are two main w...
