Problems solved by technology

Because the parasitic wasp is polyembryonic, it can complete two generations of reproduction during the eclosion period of the alfalfa leaf-cutter bee, and the parasitism rate to the alfalfa leaf-cutter bee can reach more than 75%, which has caused serious harm to the population expansion of the alfalfa leaf-cutter bee, resulting in Alfalfa Leafcutter Bee Reproduction Decrease
For trapping and killing parasitic wasps of alfalfa leafcutters, dichlorvos and incandescent lamps are commonly used at home and abroad for trapping and killing. Because dichlorvos is heated and decomposed, it releases toxic gases of phosphorus oxide and chloride. Improper use can easily poison people and cause serious harm to bees. Toxic; after use, it needs to be ventilated, and it is easy to reduce the temperature and humidity of the artificial climate chamber, which is not good for the development of alfalfa leafcutter bees with a longer eclosion period

Embodiment 1

[0023] This embodiment provides a method for trapping and killing parasitoid wasps of Alfalfa Leafcutter. The method of trapping and killing adopts the method of black light and proparthrin for the first time, the black light is used to lure the parasitic wasps, and the proparthrin is used to kill the parasitic wasps or reduce the activity of the parasitic wasps. This trapping and killing method is carried out in an artificial climate chamber, and the parasitic wasp trapping and killing is synchronized with the emergence of the alfalfa leafcutter bee, specifically including the following steps.

[0024] (1) The environmental conditions in the artificial climate chamber were set at a constant temperature of 30°C and a relative humidity of 60%, which provided suitable environmental conditions for the emergence of the cocoons of the alfalfa leafcutter bees. The cocoons of the alfalfa leafcutter bee are placed in a bee hatching tray, and the bee hatching tray is installed in an ar...

Embodiment 2

[0030] Using the trapping and killing method of the alfalfa leafcutter parasitoid described in Example 1, the emergence experiment of the alfalfa leafcutter parasitoid was carried out to verify the effectiveness of the trapping and killing method described in Example 1.

[0031] (1) Test materials and facilities

[0032] 1,500 cocoons of alfalfa leafcutter bees, 5 bee hatching trays, 5 15W black light lamps (manufactured by Philips), 5 white water trays, electric mosquito-repellent incense liquid (the active ingredient is 1.5% proparthrin), and control chemical trapping The agent uses DEET (insect repellent amine).

[0033] Artificial climate chamber, press 10m in the artificial climate chamber 2 Install a chemical trap volatilization device, and add electric mosquito coil liquid or DEET into the chemical trap volatilization device according to the experimental design. The environmental conditions in the artificial climate chamber were set at a constant temperature of 30°C a...

Abstract

The invention discloses a trap-killing method for megachile rotundata fabricius parasitic wasps. The method comprises the steps that 1, megachile rotundata fabricius bee hatching plates are placed inphytotron, water trays are arranged below the bee hatching plates, black light lamps are installed between the bee hatching plates and the water trays, the black light lamps are 10 cm away from the water trays, and water in the water trays is replaced regularly; 2, a 1.5% prallethrin attractant device which is screened out is installed in the phytotron, wherein the dosage is 3.25 ml / d / 10 m<2>; 3,on the second day when megachile rotundata fabricius bee cocoons are put in the phytotron, the black light lamps and attractant volatilization device are started, observation is conducted regularly every day, the number of the parasitic wasps in the water trays and the bee hatching plates is counted separately, when observing parasitic wasps without eclosion in two days, the black light lamps areturned off, and the attractant device is removed. Accordingly, the trap-killing effect on the parasitic wasps can reach about 95%, the method is safe to megachile rotundata fabricius bee cocoons, andnormal eclosion of megachile rotundata fabricius is not affected.

Description

technical field [0001] The invention belongs to the technical field of agricultural insect prevention and control, and relates to the artificial breeding of alfalfa leaf-cutter bees, in particular to a method for trapping and killing parasitic wasps of alfalfa leaf-cutter bees. The invention adopts the method of black light combined with chemical traps to trap and kill the parasitic wasps before or at the same time as the alfalfa leafcutter bee emerges. Background technique [0002] Alfalfa ( Medicago sativa ), also known as alfalfa or common alfalfa, is known as the king of pastures due to its richness in protein, amino acids, vitamins and various nutrients. A prominent problem encountered in the promotion of alfalfa cultivation is the lack of sufficient quantity of seeds. One of the important experience of its high yield is to use alfalfa leaf cutter bee to pollinate alfalfa. In countries with developed animal husbandry, the use of alfalfa leafcutters to pollinate alfal...
