Description
Technical field
The present invention relates to field of biotechnology, and in particular to a kind of Metarhizium anisopliae bacterial strain and its application.
Background technique
Gryllotalpa spp Orthoptera Gryllotalpidae insect, popular name mole cricket, ground draw mqb, and common mainly has Oriental burmeister, North China mole cricket
Mqb etc..Mole cricket mainly passes through adult and saps a gallery under soil, Plant species eaten root and tender stem, and leads to the root and soil of plant indirectly
It is detached from, causes plant seedlings withered.Mole cricket is liked in soft, tunneling in wetland.Mole cricket is omnivorous insect, several
All crops, especially crop seeding and seedling raising phase are endangered, nursery failure or the underproduction are often resulted in, are a kind of important subterranean pest-insects,
How to prevent and treat is a problem in the urgent need to address.
The method of prevention and treatment mole cricket mainly has at present: (1) light trap: mole cricket has apparent phototaxis, using black light lamp,
Larger in relative humidity, wind speed is small, no moonlight, the sultry dusk rained fastly, can trap a large amount of mole cricket;(2) horsehit is fresh
Grass trapping: the organic matters compost such as mole cricket team horsehit has very strong taxis, stacks ground or organic matter place abundant, mole cricket in muck
Mqb is just clustered in this, is also often a common method in mole cricket prevention and treatment using muck plus poison trapping, such as Lv Jie patent: one
(the patent No.: 201310583677.8) described in the formula of the organic fertilizer of kind prevention mole cricket;(3) chemical pesticide period poison bait:
Mole cricket has stronger chemotaxis, and to half-mature millet is boiled, soya-bean cake or wheat bran have very strong hobby, utilize these materials
Poison is smeared, mole cricket can be trapped and killed,;(4) Extracts from Plant Recourses is trapped and killed: as yellow big patent (patent No.:
201711094609.X;A kind of mole cricket killing agent being not likely to produce drug resistance) described in, Li Yong pivot stores, and the extracts such as borneol are mixed
Close mole cricket insecticide made of object;Biological control: currently without using bacterium, the natural pathogenic microorganism of the mole crickets such as fungi or virus
The report for preventing and treating mole cricket.Physical method prevention and treatment, not only needs to put into a large amount of black light lamp, higher cost, and effect is general.Chemistry
Pesticide poison bait, control efficiency is pretty good, but be easy to cause environmental pollution, and endangers to the health care belt of humans and animals.Separation identification
There is higher killing ability to mole cricket, and to the natural pathogenic microorganism of person poultry harmless, biological control is carried out to mole cricket, is one
Good selection.
Summary of the invention
The object of the present invention is to provide the Metarhizium anisopliae bacterial strains that a kind of pair of mole cricket class pest has stronger infection ability

Illustrate: sequence alignment result shows, all gold in the Metarhizium anisopliae and current database of this patent separation
Tortoise green muscardine fungus ITS different and most like HZ1 strains has 96.42% similitude.
Oriental burmeister killing ability measures in 3 rooms Metarhizium anisopliae bacterial strain JXAS-03
Metarhizium anisopliae bacterial strain JXAS-03 inoculation is lined on PDA plate, is placed in 27 degrees Celsius, relative humidity
It is cultivated in 80% constant temperature and humidity incubator, covers with entire plate to fungi, it, will with 0.05% Tween-80 solution washing plate
Fungal spore rinses, and is filtered to remove the fungus sporophore of bulk after collection conidium with filter paper.With cell count instrument meter
After number conidial suspension concentration, it is 1 × 10 that conidium, which is diluted to concentration with 0.05% Tween-80 solution,5, 1 × 106,
1×107Spore/mL solution.Three repetitions of each concentration, 10 mole cricket adults of each repeating groups.Spore suspension handles mole cricket
Mqb adult uses infusion method, i.e., each mole cricket adult is pressed into spore suspension liquid level or less with tweezers and maintained 3 seconds.
0.05% Tween-80 is as blank control.Treated, and mole cricket adult is put in 27 degrees Celsius, the constant temperature and humidity of relative humidity 80%
It is cultivated in incubator, takes out and record dead bombys batryticatus quantity daily, calculate the death rate of each concentration, data are as follows: chafer
Mole cricket killing ability test result is as shown in table 1 in the room Metarhizium Strains JXAS-03:
Table 1
Spore suspension concentration (spore/mL) | Death rate % (Mean Death number/10) |
1*105 | 43.3% (4.33/10) |
1*106 | 60% (6/10) |
1*107 | 83.3% (8.33/10) |
As shown in table 1, Metarhizium anisopliae bacterial strain JXAS-03 of the invention is stronger to indoor mole cricket killing ability.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, the present invention
Claimed range is delineated by the appended claims, the specification and equivalents thereof from the appended claims.
