ʻO Bacillus thuringiensishe mea pepehi kanaka microbial haʻahaʻa ka ʻawahia. Hoʻopuka nui ia i ʻelua ʻano mea ʻawahia, ʻo ia hoʻi nā endotoxins (nā inclusions kristal) a me nā exotoxins, ka mea e hoʻōki ai i ka hānai ʻana o nā mea ʻino a make i ka pōloli, ka palaho o ke koko a me ka neurotoxicity.
ʻAno hana pepehi pepeke
Ma hope o kaʻO Bacillus thuringiensisKe ʻai ʻia e ka pest, hoʻopulapula ia i loko o ka ʻōpū waena o ka mea hoʻokipa. Ma ke ʻano alkaline kūpono i loko o ka ʻōpū, ulu a hoʻohua hou ia. Hoʻoheheʻe ʻia nā mea ʻawahia kristal e nā proteases i loko o ke ala ʻōpū o ke kino pepeke, e hana ana i nā subunits ʻawahia liʻiliʻi. Hana kēia mau subunits ma nā cell epithelial ʻōpū o ke kino pepeke, e hana ana i ka maʻi lolo ʻōpū, perforation, paralysis o ke kino pepeke, a me ka pau ʻana o ka hānai ʻana. Ma hope iho, komo ka Bacillus thuringiensis i loko o ke koko no ka hoʻohua hou ʻana, e hana ana i ka septicemia a alakaʻi i ka make ʻana o ka pepeke.
Nā pōmaikaʻi o Bacillus thuringiensis:
(1) Hoʻokō ke kaʻina hana i nā koi palekana o ke kaiapuni. Ma hope o ka pīpī ʻana i ka insecticide, he liʻiliʻi ke koena i koe ma ke kula.
(2) Haʻahaʻa ke kumukūʻai hana. Loaʻa nā mea maka ma nā wahi āpau a he mau huahana mahiʻai a me nā huahana ʻaoʻao a pau, me nā kumukūʻai haʻahaʻa.
(3) He nui nā hopena pepehi pepeke o ka huahana. He mea ʻawahia ia i nā ʻano mea ʻino lepidopteran he 200 a ʻoi.
(4) ʻO ka hoʻohana mau ʻana e hoʻokumu i kahi maʻi ahulau o nā mea ʻino, e hoʻoulu ai i ka laha ākea o nā hua pathogen pest, e hoʻokō ai i ke kumu o ka kaohi kūlohelohe ʻana i ka nui o ka heluna pest.
(5) ʻAʻohe ona haumia i ke kaiapuni a me nā kumu wai, ʻaʻohe mea ʻino i nā kānaka a me nā holoholona, a palekana no ka hapa nui o nā pepeke ʻenemi kūlohelohe.
(6) Hiki ke kāwili ʻia a hoʻohana koke ʻia me nā ʻano mea hoʻomākaukau olaola ʻē aʻe, nā mea hoʻoponopono ulu pepeke, nā mea ʻawahia pyrethroid spirochete, carbamate, nā pesticides organophosphorus, a me kekahi mau fungicides a me nā mea hoʻouluulu kemika.
(7) ʻO ka hoʻololi ʻana i ka hoʻohana ʻana i nā insecticides me nā pesticides kemika hiki ke hoʻomaikaʻi i ke kūpaʻa o nā mea ʻino i nā pesticides kemika.
Nā kuhikuhi hoʻohana
E kāohi i nā mea ʻino ʻai lau e like me nā anuhe jujube, ka nalo jujube, ka nalo ʻawahia, a me ka nalo prickly. E pīpī i ka Bt emulsion ma ka nui o 500-600 mau manawa i ka wā mua o ka ulu ʻana o ka larvae. Hāʻawi kēia ʻano hana i nā hopena maikaʻi i ka kāohi ʻana i nā mea ʻino a me ka pale ʻana i nā lau.
E kāohi i ka moth jujube a me ka apple codling, a me ka moth pea codling. I ka wā o ka wā hoʻomoe hua a ka moth makua a me ka wā ʻai hua a ka larvae, e pīpī i ka Bt emulsion (loaʻa ka 0.2% synthetic pyrethroid) ma ka nui o 500-600 mau manawa ma mua o ka hoʻouka ʻana o nā larvae i ka hua. Hāʻawi kēia ʻano hana i nā hopena maikaʻi i ka pepehi ʻana i nā mea ʻino a me ka pale ʻana i nā hua.
Nā Mālama
① ʻAʻole hiki ke hoʻohuihui ʻia me nā mea hoʻomaʻemaʻe.
② Pono e pale ʻia ka hoʻohana ʻana i ka wahi hānai ilo silika i mea e pale aku ai i ka make ʻana o ka ilo silika.
③ Hana maikaʻi ʻo Bacillus thuringiensis i ka wā e kiʻekiʻe ai ka mahana (ma luna o 20℃). He mea kūpono ke hoʻohana ʻia mai Iune a Kepakemapa.
④ He mea maʻalahi kēia mea i ka omo ʻana i ka wai a e hana i nā puʻupuʻu. Pono e mālama ʻia i kahi paʻa, maloʻo a me kahi anuanu.
