Bacillus thuringiensis, e tsejoang hape e le Bacillus thuringiensis var. popilliae, ke baktheria e bōpehileng joaloka molamu. Nakong ea ho ikatisa ha eona, ntlha e 'ngoe e etsa spore, kahoo e fetoha baktheria e etsang spore, ha ntlha e 'ngoe e hlahisa liprotheine tsa kristale. Liprotheine tsena tsa kristale li na le phello e matla ea ho bolaea likokoanyana, haholo-holo bakeng sa mefuta e fetang 100 ea likokoanyana tse senyang lijalo tse kang cotton bollworm, small cabbage moth, diamondback moth, raese budworm, silkworm, phaene caterpillar, koae budworm, corn borer, cotton bollworm, raese streaked stem borer, grass moth le ground beetle. Ke chefo e bolaeang likokoanyana e 'nileng ea etsoa lipatlisiso tse tebileng ka ho fetisisa, nts'etsopele e potlakileng ka ho fetisisa, le ts'ebeliso e pharaletseng ka ho fetisisa lilemong tsa morao tjena. Ka lebaka la chefo ea eona e tlase, botsoalle ba tikoloho, le phello e ntle ea ho bolaea likokoanyana, e ratoa haholo ke balemi.
I. Litšobotsi tse ka Sehloohong tsaBacillus thuringiensis
1. Mefuta e mengata eaTaolo ea likokoanyanal: Chefo e hlahisoang ke Bacillus thuringiensis e ka laola tse senyang lijalo tse makholo, haholo-holo e sebetsa hantle haholo khahlanong le liboko tsa lepidopteran. E sebelisoa haholo-holo ho laola liboko tsa k'habeche, liboko tsa k'hothone, liboko tsa bosiu tsa turnip, liboko tsa bosiu tse metsero, liboko tsa bosiu tsa beetroot, liboko tse nyane tsa k'habeche, liboko tsa koae, liboko tsa raese tsa moloko oa bobeli, liboko tsa poone, liboko tsa tee, liboko tsa phaene, liboko tsa tee, liboko tsa linaoa, liboko tse khomarelang poone, liboko tsa bosiu tse nang le mapheo a silevera, le liboko tsa menoang, hammoho le tse ling tse senyang lijalo tse kang bo-maleshoane, likhofu le li-slugs.
2. Khetho: Bacillus thuringiensis e hlasela haholo-holo likokoanyana tse nang le tikoloho ea alkaline ka maleng a tsona 'me e na le phello e matla ea ho bolaea. Ha e na chefo ho batho, liphoofolo tse ruuoang, linotši, litlhapi, li-shrimp, makhala le lintho tse ling tse phelang metsing.
3. Mefuta e mengata ea tšebeliso: Bacillus thuringiensis e ka sebelisoa haholo ho k'hothone, linate tsa peanut, soya, litapole, raese, rape, tamati, li-eggplant, pepere, lik'habeche, lik'habeche tsa Chaena, cauliflower, jj. meroho, hammoho le apole, lifate tsa pere, morara, linate, litholoana tsa citrus, li-lychee, kiwi, li-longan, limango, jj. lifate tsa litholoana, 'me hape le lijalong tse fapaneng tse kang lipalesa, litlama tsa meriana tsa Chaena, jj.
4. Ha e na khanyetso: Bacillus thuringiensis ke mofuta oa libaktheria tse etsang spore tse ka hlahisang liprotheine tsa kristale ea sporulation 'me tsa sebetsa ka ntle le ka hare ho likokoanyana. Likokoanyana li ke ke tsa e-ba le khanyetso. Le hoja e se e sebelisitsoe ka mashome a 'maloa a lilemo, e ntse e le chefo e ntle ea likokoana-hloko ho fihlela kajeno.
5. Ho tsamaellana hantle: Bacillus thuringiensis e tsamaellana hantle mme e ka kopanngwa le dibolaya-dikokwanyana tse sebetsang ka potlako tse kang methomyl, avermectin, le indoxacarb, e leng se fellang ka ditlamorao tse kgolo tsa tshebedisano mmoho.
6. Ha ho tšilafalo e bakoang ke chefo tse hlano: Bacillus thuringiensis ke baktheria e bōpehileng joaloka molamu e se nang chefo ho batho, litlhapi, li-shrimp, makhala, jj., 'me ha e bake tšilafalo efe kapa efe tikolohong. Ka hona, e fetohile chefo e bolaeang likokoanyana e ratoang bakeng sa tlhahiso ea lihlahisoa tsa temo tse tala le tse se nang tšilafalo.
II. Mekhoa ea Tšebeliso ea Bacillus thuringiensis
Bakeng sa taolo ea likokoanyana tse kang tšoele ea beet e tsoekere, tšoele e nyenyane ea k'habeche le seboko sa k'habeche, e ka sebelisoa nakong ea mohato oa liboko ha likokoanyana li sa le nyane. Sebelisa ligrama tse 30-40 tsa phofo e metsi ea 2% Avisept Bacillus thuringiensis ka ekare, e kopantsoe le lik'hilograma tse 30-40 tsa metsi bakeng sa ho fafatsa ka mokhoa o ts'oanang. Sena se ka bolaea likokoanyana kapele 'me se na le phello e tšoarellang nako e telele ka lebelo le letle.
Bakeng sa taolo ea likokoanyana tse kang light moth, raese budworm, phaene caterpillar, corn borer, large moth, le needle moth, sebelisa ligrama tse 25-35 tsa 1% Avisept Bacillus thuringiensis wettable powder ka ekare, e tsoakiloeng le lik'hilograma tse 30 tsa metsi bakeng sa ho fafatsa ka mokhoa o tšoanang. Sena se ka laola kapele tšenyo e eketsehileng e bakoang ke likokoanyana.
III. Litlhokomelo bakeng sa Bacillus thuringiensis
1. Sebelisa esale pele: Jwalo ka baktheria, ha e sebediswa e le nngwe, lebelo la ho bolaya le lieha haholo. Ka hona, e lokela ho sebediswa mohatong wa pele wa ho hlaha ha dikokonyana ho laola tshenyo e bakwang ke dikokonyana hamolemo.
2. Sebelisa thapama: Khanya e matla ea letsatsi e ka bolaea baktheria ena. Ka hona, ha u sebelisa chefo ena ea likokoanyana, ho molemo ho khetha ho e sebelisa pele ho 10 hoseng kapa ka mor'a 4 thapama, ka liphetho tse ntle.
3. Tšebeliso maemong a mocheso o phahameng: Bacillus thuringiensis e sebetsa maemong a mocheso o phahameng. Ha mocheso o feta 20℃, phello e ba betere.
