Episyrphus balteaus breeding method and use of episyrphus balteaus in pollinating seed-production cruciferae crop

Abstract

The invention discloses an episyrphus balteaus breeding method. The episyrphus balteaus breeding method comprises the steps of 1) breeding next generation episyrphus balteaus in a breeding cage, 2) obtaining the next generation episyrphus balteaus, and 3) enabling episyrphus balteaus to collect pollen and carry out pollination. The invention also discloses a use of the episyrphus balteaus in pollinating a seed-production cruciferae crop; the adult episyrphus balteaus out of pupae flies in the cruciferae crop greenhouse, collects the pollen of the cruciferae crop and pollinates the cruciferae crop. The episyrphus balteaus breeding method is simple and easy to implement; the episyrphus balteaus highly adapts to the environment in the greenhouse, can be hardly affected by temperatures and humidity and can grow, develop and reproduce as along as sufficient light is supplied. The pollen collection and pollination efficiency of the episyrphus balteaus is obviously higher than that of bees, and the seed production yield is about 10% higher than that of bee pollination. The adults also have the habit of preying on aphids, and therefore, an obvious effect on controlling aphids on the crop in the greenhouse can be achieved.

Description

technical field [0001] The invention relates to a breeding method of hoverfly black-striped, and also relates to the use of hoverfly black-striped for pollination of cruciferous crops, and belongs to the technical field of hoverfly propagation and application. Background technique [0002] Bees pollinate flowering plants in nature, so that the plants can bear fruit, and they are also the main pollinators in cruciferous seed production greenhouses. However, honeybees have the following disadvantages in pollination in cruciferous seed production greenhouses: [0003] 1. The small space of the greenhouse restricts the flight of the bees. After the bees leave the nest, there will be a large number of bees hitting the greenhouse and dying. Every time a greenhouse is changed, about a quarter of the bees will die. [0004] 2. Due to the high humidity and small space in the greenhouse, bees are prone to diseases, especially paralysis, which will cause a large number of bees to die....

AI Technical Summary

Problems solved by technology

[0003] 1. The small space of the greenhouse restricts the flight of bees. After the bees leave the nest, there will be a large number of bees hitting the greenhouse and dying. Every time a greenhouse is changed, about a quarter of the bees will die.

[0004] 2. Due to the high humidity and small space in the greenhouse, bees are prone to diseases, especially paralysis, which will cause a large number of bees to die

In addition, pollination efficiency is relatively low
