ʻO ka spruce spider mites nā mea ʻeha nui o nā kumu Kalikimaka ʻo Michigan.ʻO ka hoʻohaʻahaʻa ʻana i ka hoʻohana ʻana i nā pesticides hiki ke kōkua i ka poʻe mahiʻai e pale i nā mite predatory maikaʻi, ma laila e kōkua ai i ke kāohi ʻana i kēia pest koʻikoʻi.
Ma Michigan, ʻo ka spruce spider mite (Oligonuchus umunguis) kekahi mea ʻino nui o nā kumu lāʻau coniferous.Hoʻopilikia kēia pepeke liʻiliʻi i nā kumulāʻau Kalikimaka i hana ʻia ma ke kūʻai ʻana a ke kumu pinepine nei i nā poho waiwai nui i ka mahi ʻana i ka spruce a me Fraser fir.Ma nā mahi kanu kuʻuna, he liʻiliʻi ka heluna o nā mite predatory ma muli o ka hoʻohana ʻana i nā insecticides.Pōmaikaʻi nā mite predatory i nā mea ulu no ka mea ʻai lākou i nā pests a kōkua i ka mālama ʻana i ka heluna kanaka.Me ka ʻole o lākou, e poha koke ka spruce spider mite, e pōʻino ai nā kumulāʻau.
Ke hoʻokokoke mai nei ka pūnāwai, pono e hoʻomākaukau nā mea kanu e hoʻonui i kā lākou mau hoʻolālā hahai holoholona.I mea e ʻike ai i nā mite spider spruce, pono nā mea kanu e hoʻāʻo i nā kumulāʻau he nui i kēlā me kēia mea kanu a koho pono i nā kumulāʻau mai nā kiʻekiʻe a me nā lālani i loko a i waho.ʻO nā kumu lāʻau nui aʻe e hoʻonui i ka pololei o nā mea ulu i ka wā e loiloi ai i ka heluna kanaka a me nā pilikia e hiki mai ana.Pono e mālama ʻia ka ʻike ʻana i ke kau, ʻaʻole wale ma hope o ka puka ʻana o nā hōʻailona, ​​​​no ka mea maʻamau ka lōʻihi no ka mālama pono ʻana.ʻO ke ala maʻalahi loa e ʻike ai i nā mite makua a me nā ʻōpio ʻo ia ka lulu a hahau i nā lālā ma ka papa kiʻi a pepa paha (kiʻi 1).
ʻO ka spruce spider mite egg he pōpō ʻulaʻula liʻiliʻi me ka lauoho ma waena.E ʻike maopopo ʻia nā hua i hāʻule (kiʻi 2).I ka wā hoʻoikaika kino, liʻiliʻi loa ka spider mite a he kino palupalu kona kino.He ʻano oval paʻa ka spruce spider mite me nā lauoho ma luna o ka ʻōpū.ʻOkoʻa ka ʻili o ka ʻili, akā ʻo Tetranychus spruce maʻamau ka ʻōmaʻomaʻo, ʻeleʻele ʻōmaʻomaʻo a ʻeleʻele paha, ʻaʻole keʻokeʻo, ʻulaʻula a ʻulaʻula paha.ʻO nā mite predatory maikaʻi he keʻokeʻo keʻokeʻo, keʻokeʻo waiu, ʻulaʻula a ʻulaʻula paha, a hiki ke hoʻokaʻawale ʻia lākou mai nā pest mites ma ka nānā ʻana i kā lākou hana.Ke hoʻopilikia ʻia, ʻoi aku ka wikiwiki o ka neʻe ʻana o nā mite predatory makua ma mua o nā mite pest, a hiki ke ʻike ʻia ke neʻe wikiwiki ʻana ma ka papa scout.Kolo mālie nā ʻāwīwī spruce ʻulaʻula.

ʻO nā hōʻailona o ka spruce spider mite pōʻino ʻo ia ka chlorosis, nā kui kui a me ka wehe ʻana a me nā ʻāpana lau ʻeleʻele, a hiki ke laha i ka lāʻau holoʻokoʻa.I ka nānā ʻana i ka ʻeha ma ke aniani lima, ʻike ʻia nā hōʻailona ma ke ʻano he wahi poʻe melemele liʻiliʻi a puni ka wahi hānai (kiʻi 3).Ma o ka nānā pono ʻana, ka hoʻokele kūʻē ʻana a me ka hoʻohana ʻana i nā pesticides i ʻoi aku ka pōʻino i nā mites predatory maoli, hiki ke pale ʻia nā spruce spider mites mai ka luku ʻia.ʻO ke ala maʻalahi e hoʻoholo ai i nā pono o ka hoʻokele ʻana, ʻo ia ka loiloi inā hōʻike ka hoʻokolokolo ʻana e ulu ana ka heluna kanaka a i ʻole i kahi pae o ka luku.He mea nui e hoʻomanaʻo i ka piʻi wikiwiki ʻana o ka nui o ka spruce spider mite, no laila, ʻo ka nānā wale ʻana i ka pōʻino o ka lāʻau, ʻaʻole ia e hōʻike pololei i ka pono o ka mālama ʻana, no ka mea, ʻo ka heluna kanaka i make mai ia manawa ke kumu o ka pōʻino, no laila, ʻaʻohe manaʻo o ka pipi ʻana. .
