Beauveria bassiana belongs to the subcystic bacteria, the flesh-and-blood bacteria, the genus of the bacteriological bacteria, is a broad-spectrum insect pathogen fungus, mainly asexual reproduction, the production of spores; Ball spores white pyrethroids are used in the world for pest biological control, in which China uses ball spore white stiff bacteria to control horsetail pine caterpillars and corn cocoons is the largest pest control project in the world, and achieves good sustainable pest control effect.
Overview of Beauveria bassiana
Beauveria bassiana belongs to the genus beauveria bassiana in the classification of fungi, subphylum, semidiomycete, subphylum, filospora, order, plexidiaceae, order, plexidiaceae.Beauveria bassiana is one of the insecticidal fungi widely used in biological pest control at home and abroad.The highly virulent strain of beauveria bassiana forms an invasive structure when it briefly grows on the body wall of the larva of bollworm, while the low-virulent strain produces elongated creeping hyphae on the body wall of the larva, which will absorb nutrients from the body of the insect and eventually lead to the death of the insect.
Parasitic Range of Beauveria bassiana
The host insects include lepidoptera, coleoptera, hymenoptera, homoptera, diptera, hemiptera, orthoptera, isoptera, thysanoptera, hemiptera, hemiptera, orthoptera, leatherptera, zooptera, mantidales, cockroaches and spinopoda, 15 orders, 149 families, 521 genera and 707 species.In addition, beauveria bassiana can infect 13 species, 27 genera and 6 families of acaroid hosts in arthropods, such as arachnids and polypods.Production is used in the prevention and treatment of adult, more pine sawfly moth, pine, pine inchworm, pine tip quer-civorus, sawyer, privet feet moth, corn borer, sweet potato, wheat bugs like starscream, cotton, potato, soybean budworm, caterpillar like a small budworm, peach, chestnut like armour, cutworms, gold tortoise shell, mole, skipjack and plagiodera, bugs, locust, sawfly, leafhoppers, mosquitoes, ants and other pests.
Pest Control Application
Beauveria bassiana is a broad-spectrum insecticidal fungus. Researchers at home and abroad use beauveria bassiana to control agricultural and forest pests such as corn borer, pine caterpillar, cane borer, catnip, millet elephant, orange starfish and aphids.In particular, the biological control of the corn borer and pine caterpillar has been used as a routine method in China for years.Because beauveria bassiana can effectively control the insect population without harming other natural enemies and beneficial organisms, it is completely in line with the purpose of comprehensive management of harmful organisms. At the same time, it is easy to produce in large quantities and has a competitive control cost, so it has a broad application prospect.
In the 1970 s, because the beauveria bassiana has long efficacy, no pollution, not to kill predators (feed to the beetles, lacewing flies, bud fly beneficial insects such as less affected, but the impact of mulberry silkworm) wait for a characteristic, is used as agriculture and forestry pests control in our country, but until you actually attaches great importance to the ecological, the technology to fire up gradually.
