Abstract

The invention discloses Metarhizium anisopliae and application of Metarhizium anisopliae. The Metarhizium anisopliae provided by the invention is Metarhizium anisopliae JF-6213 with CGMCC No. 5952 registered in China General Microbiological Culture Collection Center. The strain (Metarhizium anisopliae) has good production traits and strong spore production capacity, strong insecticidal activity to sugarcane moth borer, good secondary infection to sugarcane moth borer, has 7.44 days LT50 (lethal time of 50%) to 3-4 years sugarcane moth borer; the strain is used for preparing insect killing fungus preparation which can effectively control population quantity of sugarcane moth borer; moreover, Metarhizium anisopliae JF-6213 has strong pathogenicity to brontispa longissima, asiatic migratory locust, leechee stinkbug and Dysmicoccus neobrevipes Beardsley, strong secondary infection capability and high stability and is quite applicable to tropical and subtropical areas.

Description

technical field

[0001] The invention relates to a strain of Metarhizium anisopliae and its application. Background technique

[0002] Sugarcane stem borer (sugarcane stem borer), commonly known as core borer, belongs to the order Lepidoptera of the insect class Lepidoptera. Among them, there are 50 species of Mothidae insects, 12 species of Noctuidae, 1 species of Toritridae, 1 species of Pterodidae and 1 species of Pterodidae. The field density of this insect is high, and the whole growth period of sugarcane from sowing to harvesting is harmed by it. After being damaged at the seedling stage, the seedlings cannot germinate and unearth; The number and effective stems are reduced, and the dead heart rate is generally 10% to 20%, and the serious field can reach more than 60%. In the middle and late stages of sugarcane growth, larvae will damage the sugarcane stems, destroy the tissue of the sugarcane stems, and affect the growth of sugarcane. In strong winds, sugarcane stems...
