Method for preventing and controlling waxberry orchard fruit flies by using housefly pupas to replace fruit fly pupas for breeding parasitic wasps

Abstract

The invention discloses a method for preventing and controlling waxberry orchard fruit flies by using housefly pupas to replace fruit fly pupas for breeding parasitic wasps. The method comprises the steps of (1) housefly pupa obtaining and (2) pachycrepoideus vindemmiae breeding. Through the adoption of the technical scheme, pachycrepoideus vindemmiaes bred by the housefly pupas can realize higher control efficiency on the control of fruit flies, so the prevention and control cost is greatly reduced; the pachycrepoideus vindemmiae obtained by the method has the characteristics that the reproductive capacity is obviously higher, the progeny yield is obviously higher, the individual lifetime is obviously longer, the individuals are obviously larger, and the like.

Description

technical field [0001] The invention belongs to the application field of biotechnology, and more specifically relates to a method for preventing and controlling fruit flies in red bayberry orchards and using housefly pupae instead of fruit fly pupae to breed parasitic wasps. Background technique [0002] As a specialty fruit in my country, bayberry has a long history of cultivation and has recently been welcomed by more and more consumers. It has become a pillar industry for farmers in some mountainous areas in southern my country to increase production and income. The fruit ripening period of bayberry is from mid-June to July. In the first ten days of the month, the red bayberry fruit that has entered the mature stage becomes soft and has a strong fragrance, which attracts female fruit flies to lay eggs on the red bayberry fruit, and the hatched larvae eat and damage the fruit. Among them, Drosophila melanogaster is the most important fruit fly on the red bayberry fruit. Pest...

Problems solved by technology

When adopting the disclosed method of breeding fruit flies and then utilizing the pests to breed fruit fly pupal stage parasitoids, the host used is a smaller fruit fly pupa, and the bred parasitoids are smaller in individuality and fecundity, and have a shorter lifespan. , with limited ability to control Drosophila
