Embodiment 1

[0019] A large-scale breeding method for aphids, comprising the following steps:

[0020] (1) Construction and cultivation of greenhouses: according to the requirements of the breeding scale, the size of the greenhouses should be reasonably set;

[0021] (2) Planting and cultivating seedlings: plant the cultivating seedlings of Aphididae in the greenhouse, soak the celery seeds in warm water at 30°C for 15 minutes, and then sow them in the greenhouse, so that the temperature in the greenhouse is maintained at 20°C-25°C, 10-15 After sprouting in the first day, continue to cultivate for 15-20 days, so that the cotyledons are expanded to have 5-7 true leaves, and the plant height is 20-30 cm. At this time, the celery is not only young and tender, but also very suitable for the growth of aphids; among them, the cultivation of celery The density is 10-20 per square meter.

[0022] (3) Connect aphids: connect the celery seedlings in the greenhouse with aphids, each plant connects 5...

Embodiment 2

[0028] A method for preventing and controlling aphids by aphids, comprising continuously releasing the above-mentioned raised aphids to the pest-infested areas of the field, releasing the bees in 3 to 4 batches, releasing 5-10 grams of aphids per square meter, The release interval is 2-3 days; the seedlings of crops (no pests and diseases) that are normally grown in the field are continuously released, and the bees are released in 2 to 3 batches, releasing 1-3 grams of aphids per square meter, and the release interval for 20-30 days.

Embodiment 3

[0030] The test shows that the final control effect of continuous release of bees on aphids is better than spraying 300 times liquid of 10% pyridoxine wettable powder.

[0031] The number of aphids decreased rapidly after spraying pyridoxine, but with the loss of efficacy and the killing of natural enemies, the number gradually recovered 10 days after spraying. By 30 days after spraying, the average number of aphids per plant reached 50, which has exceeded the population base before spraying, and it is necessary to spray again to control the damage; while the number of aphids in the bee release area has experienced a long-term decline process Later, it tends to be relatively stable under a low population density. In addition, the natural parasitism rate of aphids in the spraying area has always been maintained at a low level, while the parasitism rate in the bee release area increased with the increase in the number of aphids, which eventually led to a decline in the number of...

Abstract

The invention discloses a method for large-scale breeding of aphidiidae and a method for control of aphids. The breeding method comprises the steps of constructing a breeding greenhouse, planting seedlings, inoculating aphids, inoculating bees, culturing aphidiidae, separating mummified aphids and the like; and the method for controlling the aphids by using the aphidiidae refers to carrying out continuous release of the aphidiidae. The methods disclosed by the invention have the advantages that large-scale breeding is realized, the bee production rate is high, the methods are simple and scientific, the control effect is good, and the efficiency is high.

Description

technical field [0001] The invention relates to a method for raising and using the aphid wasp, in particular to a method for large-scale breeding of the aphid wasp and a method for preventing and controlling the aphid, belonging to the field of biological control. Background technique [0002] Aphid wasps are endoparasitic wasps of aphids, and they are an important class of natural enemy insects, which are used to control some important aphids. However, the current aphid wasps are usually small in scale, and the application for controlling aphids is also very simple, with poor effect and low efficiency. Contents of the invention [0003] In order to solve the above problems, the present invention designs a method for large-scale breeding of aphids and controlling aphids, which realizes large-scale feeding, the method is simple and scientific, and the control effect is good and the efficiency is high. [0004] Technical scheme of the present invention is: [0005] A large...
