Bacillus thuringiensis israelensis (Bti)


Bacillus thuringiensis israelensis (Bti) is a soil bacterium that was discovered in Israel in 1977.  Bti has been used in mosquito and blackfly control for many years. The insecticide is created when the bacterium Bti is placed in unfavorable conditions it hardens and forms spores.  Within these spores is a parasporal body comprised of proteins.  These proteins have insecticidal properties.  When a mosquito larva ingests the Bti portions of the mosquito's gut rupture, killing the larva.  When we use Bti to control mosquitoes the bacteria is dead and no live organisms are released into the environment.
Bti is specific to mosquitoes, blackflies and midges. It breaks down quickly in the environment and is essentially non toxic to other insects, humans and other mammals.

Cuba baca ayat pertama sekali lagi.

Sekali lagi.

Ada yang tak kena tak?








ADA!

There is no Israel in this world !!! How come the bacterium was found in Israel?

Terkesima dengan ayat lecturer dalam kelas harini, yang part, "it was found in Israel.......... "

No, there is no Israel land.

"..........was discovered in Israel in 1977..........."

Hurmmmm..... memang la. Sebab peristiwa Nakbah tahun 1948. Sejak dari tu, mereka jadikan tanah itu sebagai tanah mereka.




Bti ni berguna sebenarnya. Dengan izin Allah ianya menjadi larvicides untuk kawal pembiakan nyamuk yang menyebabkan penyakit kepada manusia.

Tapi, saya tak boleh terima jika mengatakan ianya ditemui di Israel!

Kalaupun ianya ditemui di kawasan penuh berkah itu, nama tempat itu adalah Palestin! BUKANNYA ISRAEL. 


Diam dan mendengar tak bererti mengiyakan.
