ʻO ka Insecticide Methoprene 95% TC me ke kumukūʻai maikaʻi loa

Wehewehe Huahana

He lāʻau pepehi kanaka biochemical ia o ka papa hormone ʻōpiopio pepeke. Hiki i ka hormone ʻōpiopio pepeke ke hoʻoponopono i kona ulu ponoʻī, ka hoʻomohala ʻana, a me ke kaʻina hana metamorphosis. ʻO ka hana nui o ka hormone ʻōpio, ʻo ia ke kāohi i ka metamorphosis o nā larvae ʻōpiopio, mālama i nā ʻano o ke kahua ʻōpiopio pepeke, a noho mau i nā larvae ma hope o ka molting.

ʻO Methoprene, ma ke ʻano he mea pale no nā lau paka, hoʻopilikia i ke kaʻina hana ʻili o nā pepeke. Hiki iā ia ke hoʻopilikia i ke kaʻina hana ulu a me ka ulu ʻana o nā ʻūpā paka a me nā ʻūpā pauka paka, e hoʻolilo ana i nā pepeke makua i ko lākou hiki ke hānau hou, a pēlā e kāohi pono ai i ka ulu ʻana o ka heluna o nā mea ʻino lau paka i mālama ʻia.

ʻAʻole hiki i nā hormones ʻōpiopio pepeke ke pepehi pololei i nā pepeke, hiki iā lākou ke hoʻomake iā lākou i ka wā o ka metamorphosis, a i ʻole e hōʻemi i ka heluna o nā keiki ma o ka hānau ʻole ʻana a i ʻole ka hua ʻole ʻana o nā hua. No laila, lohi ko lākou hopena a ʻaʻole hiki iā lākou ke kāohi koke i ka pōʻino o nā mea pahū, e kaupalena ana i kā lākou hoʻohana ʻana i ka mahiʻai. I kēia manawa, hoʻohana nui ʻia ia ma nā ʻano penei:

1. Kāohi a me ka kaohi ʻana i nā mea ʻino olakino. He hana kiʻekiʻe ko Fenpropathrin e kūʻē i nā ʻūhini Kelemania a hiki ke hoʻoulu i ka hānau ʻole ʻana i nā wāhine a me nā kāne makua. ʻO ka mālama mau ʻana me kēia lāʻau lapaʻau hiki ke hoʻopau iā ia ma muli o ka hānau ʻole ʻana ma hope o ʻeono mahina a i hoʻokahi makahiki, a he kūpono hoʻi ia i nā ʻūhini nui. ʻO ka hana ʻana i kahi mea hoʻokuʻu mau o ka methoprene he mea kūpono hoʻi ia i ka pale ʻana a me ka mālama ʻana i nā ʻuku, nā makika, a me nā nalo.

2. Kāohi i nā mea ʻino Hemiptera. He kūpono ʻo Fenvalerate i ka kāohi ʻana i nā aphids hale kōmahana a me nā whiteflies a ua kākau inoa ʻia ma ʻAmelika Hui Pū ʻIa. Akā, ʻaʻole maikaʻi ke kūpaʻa ke hoʻohana ʻia ma ke kula. He kūpono ʻo Dioxycarb i ka kāohi ʻana i nā whiteflies hale kōmahana a me nā crustaceans.

3. Kāohi a me ka kaohi ʻana i nā mea ʻino mālama. He hana kiʻekiʻe ko ka hormone ʻōpiopio e kūʻē i nā mea ʻino Lepidoptera i ka wā mālama, e like me nā palaoa, ka palaoa, a me ka paka. Ma ʻAmelika Hui Pū ʻIa, ua hoʻāʻo ʻia he pono ia e kūʻē i nā mea ʻino mālama he nui, e like me fenpropathrin a me carbendazim.

4. Kāohi a me ke kāohi ʻana i nā ʻanuʻu. Hiki i ka maunu Fenpropathrin ke keakea i ka metamorphosis maʻamau o nā larvae ʻino, hoʻolilo i ke aliʻi ʻanuʻu i sterile, a kāohi pono i nā ʻanuʻu kīhini. Aia kekahi mau hōʻike e pili ana i ka hoʻohana ʻana i nā hormones ʻōpio e mālama i nā ʻanuʻu.

5. Hoʻonui i ka hana ʻana o ka silika. ʻO ka pīpī ʻana i ka hormone ʻōpio a i ʻole ka hormone pseudojuvenile e like me ka hormone anti juvenile ma ka noho o ka silkworm (2-4 micrograms/poʻo) a i ʻole ma ke kino o ka silkworm instar 5 (1-3 micrograms/poʻo) hiki ke kāohi i ka metamorphosis, hoʻolōʻihi i ke kahua larval instar 5 ma mua o hoʻokahi lā, hoʻonui i ka ʻai ʻana, hoʻonui i ka nui o kēlā me kēia kanaka, a hoʻonui i ka hana silika. Ma keʻano laulā, hiki iā ia ke hoʻonui i ka nui o 10000 cocoons ma kahi o 15%.

Ke hoʻohana nei i nā ʻano hana

1. E mālama i nā lau paka e pale aku i nā nalo paka. E pīpī pololei i ka 41% pauka hiki ke hoʻoheheʻe ʻia he 40000 manawa o ka wai ma luna o nā lau paka. No ka hōʻoia ʻana i ka pīpī like ʻana a me ka uhi piha ʻana o nā lau paka, hiki ke hoʻohana ʻia ka dilution quantitative a i ʻole nā ​​​​lako pīpī haʻahaʻa haʻahaʻa multi-directional kūikawā.

2. ʻOkoʻa ka ʻike o nā pepeke i nā hormones ʻōpiopio i nā pae like ʻole o ka ulu ʻana a me ka ulu ʻana. ʻOi aku ka ʻike o nā larvae a i ʻole nymph i ka pae hope loa, ʻoiai ʻoi aku ka liʻiliʻi o nā pae ʻē aʻe. I ke kaʻina hana o ka ulu ʻana a me ka ulu ʻana o nā pepeke, koho ʻia ka manawa kūpono a hoʻohana ʻia nā hormones ʻōpio exogenous e hoʻopilikia i ke kaulike hormone maʻamau i loko o ke kino o nā pepeke, e hoʻoulu ai i ka metamorphosis maʻamau ʻole, ka hānau ʻole ʻana o ka pākeke, a i ʻole ka hiki ʻole ke hoʻohua i nā hua, a pēlā e hoʻokō ai i ka pahuhopu o ka kaohi ʻana a me ka hoʻopau ʻana i nā mea ʻino.

3. ʻO ka IC50 fenvalerate no ka ʻenuhe Culex pipiens he 0.48 micrograms i ka lita, a ʻo ka ID50 fenvalerate no nā pupae moth wax he 2.2 micrograms i ka pupa.
