Biopesticides: Bacillus thuringiensis a me Spinosad

Ke ʻimi nei nā māla i nā mea pani no nā pesticides maʻamau.Ke hopohopo nei kekahi e pili ana i ka hopena o kahi kemika kūikawā i ko lākou ola kino.

Ke hoʻololi nei nā poʻe ʻē aʻe mai ka hopohopo no nā hopena ʻino i ka honua a puni lākou.No kēia mau māla, hiki i nā biopesticides ke lilo i mea ʻoi aku ka maʻalahi akā ʻoi aku ka maikaʻi.

Ua kapa ʻia ʻo biopesticides i nā pesticides kūlohelohe a olaola paha.ʻAʻohe mea ʻawaʻawa i nā mea ola ʻole a me ke kaiapuni.

ʻO Bacillus thuringiensis a me Spinosad ʻelua mau lāʻau pesticides maʻamau.ʻO ka mea kūikawā, he microbial insecticides lākou.

Ma ka laulā, ʻokoʻa nā ʻano ʻano Bacillus thuringiensis a ʻoi aku ka laulā o Spinosad.

He aha ka Microbial Insecticides?

He inoa pōkole no nā microorganism.ʻO kēia nā meaola liʻiliʻi ʻaʻole hiki iā mākou ke ʻike iā lākou me ka maka ʻōlohelohe.

I ka hihia o ka microbial insecticides, ke kamaʻilio nei mākou e pili ana i nā microbes i mea pōʻino ʻole i ka poʻe, akā make i nā pest insect.

ʻO ka mea hana i loko o kahi insecticide microbial ʻo ia ka microbe ponoʻī.ʻO ia paha he bacteria, fungi, protozoa, microbe-carrying nematodes, a i ʻole he virus.

Aia maoli ka Bacillus thuringiensis (Bt) i ka lepo, ka wai, a me ka ʻili o nā mea kanu.Noho ʻo Saccharopolyspora spinosa (Spinosad) i ka lepo.

Pehea e hana ai i ka Microbial Insecticides?

E like me nā kānaka a me kā lākou mau mea kanu māla, hiki ke hoʻopilikia ʻia nā ʻōpala i nā microbes.Hoʻohana ka microbial insecticides i kēia nāwaliwali.

Loaʻa iā lākou kahi kiʻekiʻe o kahi microorganism i ʻike ʻia ma ke ʻano a ʻike ʻia e hoʻopilikia i nā ʻōpala ʻokoʻa.ʻAi ka microbe i ka pest.

ʻO ka hopena, ua maʻi nui ka pest no ka hoʻomau ʻana i ka ʻai a ʻaʻole hiki ke hana hou.

Pili ʻo Bt i ke kaʻina larval (anuhe) o nā pūʻulu pest.I ka ʻai ʻana o nā anuhe, e like me nā hornworms, i ka Bt, hoʻomaka ia e ferment i loko o ko lākou ʻōpū.

ʻO nā mea ʻawaʻawa e hoʻopuka ai ke kumu e pau ai ka ʻai ʻana o nā enuhe a make i kekahi mau lā ma hope.

ʻO nā ʻano ʻano kikoʻī o Bt i kuhikuhi i nā pūʻulu pest kikoʻī.Bt var.ʻO kurstaki ke kiʻi i nā anuhe (butterfly and moth larvae), no ka laʻana.

Bt var.ʻO ka ʻimi ʻo israelensis i ka lele lele, me ka makika.E koho pono i ka ʻano Bt kūpono no kāu pest insect.

ʻO Spinosad kahi lāʻau insecticide microbial ākea ākea.Hoʻopilikia ia i nā anuhe, nā mea liʻiliʻi lau, nā nalo, nā thrips, nā pipi, a me nā mite spider.

Hana ʻo Spinosad ma ka hoʻouka ʻana i ka ʻōnaehana nerve i ka wā e ʻai ai ka poʻe pest.E like me Bt, pau ka ʻai ʻana o nā mea ʻino a make i kekahi mau lā ma hope.
