No ke aha i kū'ē ai nā mea kanu kū'ē i nā pepeke i hoʻololi ʻia?Hoʻomaka kēia me ka loaʻa ʻana o ka "gene protein-resistant".ʻOi aku ma mua o 100 mau makahiki i hala aku nei, ma kahi hale wili ma ke kūlanakauhale liʻiliʻi o Thuringia, Kelemānia, ua ʻike nā kānaka ʻepekema i kahi huakini me nā hana insecticidal a kapa ʻia ʻo Bacillus thuringiensis ma hope o ke kaona.ʻO ke kumu e hiki ai i ka Bacillus thuringiensis ke pepehi i nā pepeke no ka mea aia kahi "Bt insect-resistant protein" kūikawā.He kikoʻī loa kēia Bt anti-insect protein a hiki ke hoʻopaʻa wale i nā "receptor specific" i loko o ka ʻōpū o kekahi mau pests (e like me nā pests "lepidopteran" e like me nā moth a me nā pepeke), e hoʻoheheʻe ʻia nā pests a make.ʻAʻole loaʻa i nā ʻōpū o ke kanaka, nā holoholona a me nā inike ʻē aʻe (non-"Lepidopteran" insects) "nā mea loaʻa kikoʻī" e hoʻopaʻa i kēia pūmua.Ma hope o ke komo ʻana i ka digestive tract, hiki ke ʻeli wale ʻia ka protein anti-insect, a ʻaʻole e hana.
No ka mea ʻaʻole ʻino ka protein anti-insect Bt i ke kaiapuni, nā kānaka a me nā holoholona, bio-insecticides me ia ʻo ka mea nui i hoʻohana pono ʻia i ka hana mahiʻai no nā makahiki he 80.Me ka hoʻomohala ʻana o ka ʻenehana transgenic, ua hoʻololi nā mea hoʻouluulu mahiʻai i ka gene "Bt insect-resistant protein" i loko o nā mea kanu, e hana ana i nā mea kanu ke kūpaʻa i nā inike.ʻAʻole e hana nā polokina kūʻē i nā pepeke e hana ana i nā pests ma luna o ke kanaka ma hope o ke komo ʻana i ka ʻāpana hoʻoheheʻe kanaka.No mākou, hoʻokahe ʻia a hoʻohaʻahaʻa ʻia e ke kino kanaka e like me ka protein i ka waiū, ka protein i ka puaʻa, a me ka protein i nā mea kanu.Wahi a kekahi poʻe, e like me ke kokoleka, i manaʻo ʻia he mea ʻono e nā kānaka, akā ua ʻona ʻia e nā ʻīlio, hoʻohana nā mea kanu kūʻokoʻa i ka genetically modified i nā ʻano like ʻole, ʻo ia hoʻi ke ʻano o ka ʻepekema.
