Gukoresha Bacillus thuringiensis

Bacillus thuringiensisni umuti wica udukoko utera udukoko duke. Ukora ubwoko bubiri bw'uburozi, ari bwo endotoxins (ibice by'ubutare) na exotoxins, bituma udukoko tureka kurya ndetse amaherezo tugapfa kubera inzara, kwangirika kw'amaraso no kurwara ubwonko.

Uburyo bwo kwica udukoko

Nyuma yaBacillus thuringiensisIyo utwo dukoko twanyoye, tugenda dutera udukoko mu nda y’umuntu. Mu butaka bukwiye bwa alkaline mu mara, turakura kandi tukororoka. Uburozi bwa kristu buterwa na poroteyine mu mara y’udukoko, bugakora utundi duto tw’uburozi. Utwo dukoko bikora ku tunyangingo tw’amara tw’udukoko, bigatera ubumuga bw’amara, gutobora, guhagarara k’umubiri w’udukoko, no guhagarika kurya. Nyuma yaho, Bacillus thuringiensis yinjira mu mwobo w’amaraso kugira ngo yororoke, bigatera sepsis kandi bigatera urupfu rw’udukoko.

Ibyiza bya Bacillus thuringiensis:

(1) Uburyo bwo gukora bukurikiza ibisabwa mu kurengera ibidukikije. Nyuma yo gutera umuti wica udukoko, hasigara ibisigazwa bike mu murima.

(2) Igiciro cyo gukora ni gito. Ibikoresho byayo fatizo biraboneka cyane kandi byose ni ibikomoka ku buhinzi n'ibikomoka ku bimera, kandi ibiciro byabyo biri hasi cyane.

(3) Iki gicuruzwa gifite ingaruka nyinshi zo kwica udukoko. Ni uburozi ku moko arenga 200 y'udukoko twa lepidopter.

(4) Gukoresha ibihingwa mu buryo buhoraho bizatuma udukoko dukwirakwira cyane, bigatuma imbuto z’udukoko zikwirakwira cyane, bityo bikagera ku ntego yo kugenzura ubucucike bw’udukoko mu buryo busanzwe.

(5) Nta cyanduza ibidukikije n'amasoko y'amazi gifite, nta ngaruka mbi ku bantu no ku matungo, kandi nta ngaruka mbi ku dukoko twinshi tw'umwanzi karemano.

(6) Ishobora kuvangwa igakoreshwa ako kanya hamwe n'indi miti itandukanye ya biyoloji, imiti igenzura ikura ry'udukoko, uburozi bwa pyrethroid spirochete, carbamate, imiti yica udukoko ya organophosphorus, hamwe n'imiti imwe n'imwe irwanya udukoko n'ifumbire mvaruganda.

(7) Guhinduranya ikoreshwa ry'imiti yica udukoko hamwe n'imiti yica udukoko bishobora kongera ubushobozi bw'udukoko bwo kurwanya imiti yica udukoko.

Amabwiriza yo gukoresha

Kurwanya udukoko twangiza amababi nka jujube caterpillars, jujube moth, jujube moth, na crisp moth. Siga Bt emulsion ku gipimo cya 500-600 mu ntangiriro z'imikurire y'udukoko. Ubu buryo butanga umusaruro mwiza mu kurwanya udukoko no kurinda amababi.

Kurwanya inzoka zo mu bwoko bwa jujube na pome codling moth, ndetse n'inzoka zo mu bwoko bwa pear codling moth. Mu gihe cy'amagi y'inyenzi nini no mu gihe cy'amabyi yo kurya imbuto, siga Bt emulsion (irimo 0.2% synthetic pyrethroid) ku kigero cya 500-600 mbere yuko inyenzi zitera imbuto. Ubu buryo butanga umusaruro mwiza mu kwica udukoko no kurinda imbuto.

Amabwiriza yo Kwirinda

① Ntibishobora kuvangwa n'imiti yica udukoko.

② Aho ubworozi bw'inyonyi bukorerwa hagomba kwirinda kuhakoresha uko bishoboka kose kugira ngo hirindwe uburozi bw'inyonyi bukorerwa.

③ Bacillus thuringiensis ikora neza iyo ubushyuhe buri hejuru (hejuru ya 20℃). Ni byiza kuyikoresha kuva muri Kamena kugeza muri Nzeri.

④ Iyi miti ikunze kwinjirwa n'ubushuhe kandi ikora uduce duto. Igomba kubikwa ahantu hafunze, humutse kandi hakonje.
