Problems solved by technology

For a long time, they have been controlled by chemical pesticides. Chemical pesticides pollute the environment, increase the residual harmful pesticides in vegetables, and increase the resistance of pests such as diamondback moth and whitefly, making it more difficult to control them with pesticides.

Embodiment Construction

[0021] The present invention will be further described below in conjunction with specific examples.

[0022] 1. The morphology and biological characteristics of the strain

[0023] The bacterial strain was cultivated on different mediums, and the culture characteristics on Sabouraud plate medium, PDA plate medium and PCA plate medium were similar, and the plate medium was streaked and cultured, and the growth was slow within 48 hours, and the hyphae grew faster thereafter. , the thickness of the bacterial lawn of the strain in each medium is Sabouraud medium > PDA medium > PCA medium, the surface of the bacterial lawn is dry, no pigment, no pigment penetrates into the medium, and no special smell. On Sabouraud's medium, the mycelium is fluffy and white at the initial stage of growth. After 5 days of cultivation, the colony is light yellow and conidia are formed; on PDA medium and PCA medium, the mycelium is powdery, and the colony is white at the initial stage. , After 4 days...

Abstract

The invention discloses a Beauveria bassiana HFW-O5 bacterial strain CGMCC No.2356. The bacterial strain is separated from the Bemisia tabaci corpse in the tomato greenhouse in the suburb of Baoding city. The bacterial strain has no harmful effects for the human beings and the survival environment of the human beings and has very high toxic effects for the Bemisia tabaci, small white butterflies, aphids and other pests, the field efficacy trials for the field prevention and treatment of Bemisia tabaci, small white butterflies, aphids and other pests prove that the prevention and the treatment effects of the three pests of Bemisia tabaci, small white butterflies and aphids can achieve more than 70 percent.

Description

technical field [0001] The invention relates to a Beauveria bassiana strain and its application, in particular to a Beauveria bassiana HFW-05 strain and its application in preventing and controlling vegetable whitefly, diamondback moth and other pests. Background technique [0002] In recent years, with the development of protected vegetables, whitefly and diamondback moth have become important pests of vegetables. Whitefly has been seriously harmful since the large-scale outbreak in northern my country in 1976. In recent years, Bemisia tabaci has also broken out successively in Beijing, Hebei, Xinjiang, Tianjin, Guangzhou and other places, causing serious losses of vegetables, especially facility vegetables, and in severe cases, the yield can be reduced by more than 70%. Plutella xylostella is the most resistant vegetable pest, and its production and control are extremely difficult. Whiteflies can also transmit a variety of diseases caused by viruses. For a long time, the...
