Abstract

Provided is acremonium implicatum CQBBW8. The preservation number is CGMCC No.11440. The sequence homology between the rDNA-ITS sequence of the acremonium implicatum and the isolate LR2 of the acremonium implicatum reaches up to 98%. The acremonium implicatum CQBBW8 which is separated from citrus red mite bodies is good in production character and fast in growth, and the colony diameter can reach 5.083 cm after culture is performed for 15 days. Meanwhile, the killing activity on various pests is high, the pest killing effect is good, and the death rate of third instar larva of papilio xuthus linnaeus reaches up to 100%, the death rate of aphids reaches up to 100%, and the death rate of citrus red mites reaches up to 100% when the acremonium implicatum with 10<6> conidia / mL is used for killing the pests. An insecticidal fungus preparation produced through the acremonium implicatum effectively controls the colony quantity of various pests.

Description

technical field

[0001] The invention relates to a new microbial strain, in particular to an acremonium acremonium strain and application thereof, belonging to the field of biological pesticides. technical background

[0002] Since the invention of chemical pesticides, chemical pesticides have grown at an astonishing rate of 5% per year. Although in the past few decades, chemical pesticides have played an important role in agriculture as an increase in production and pest control, the extensive use of chemical pesticides has brought about serious "3R" problems (i.e. resistance to pesticides, residence of pesticide residues, No matter how rampant Resurgence is, it has also brought a series of ecological and environmental problems. Long-term extensive use of chemical pesticides has led to an increase in drug-resistant pests. Especially in the past 10 years, the resistance of cotton bollworms, aphids, diamondback moths, and Spodoptera litura to pyrethroids and organophosphorus ...
