Pehea e wehe ai i nā psyllids (psyllids)

Aia ma kahi o 100 mau ʻano lau i loaʻa ma ʻAmelika ʻĀkau. Eia pehea e ʻike ai iā lākou a hoʻopau iā lākou me ka hoʻohana ʻana i nā lāʻau lapaʻau i hōʻoia ʻia, kūlohelohe a kūlohelohe.

ʻO nā lice lau, i kapa ʻia i kekahi manawa ʻo ka lele lele, ʻai i nā mea kanu like ʻole, me ka hapa nui o nā kumulāʻau hua a me nā hua liʻiliʻi, a me nā tōmato a me nā ʻuala. ʻAi ʻia nā mākua a me nā nymphs ma ke ʻoki ʻana i ka ʻili o ka lau a me ka unuhi ʻana i ke kohu o ke kelepona. ʻO kēia ka mea e melemele ai ka lau (ʻoi aku ka nui o nā lau o luna) a make. Hoʻokuʻu ʻia ʻo Honeydew mai nā lau e hoʻoikaika i ka ulu ʻana o nā ʻeleʻele ʻeleʻele. Nui nā ʻano mea lawe i nā maʻi maʻi.

Kaʻike

ʻO nā mākua (1/10 ʻīniha ka lōʻihi) ʻulaʻula-ʻulaʻula ka waihoʻoluʻu, me nā ʻēheu alohilohi a me nā wāwae lele ikaika. He ʻeleu loa lākou a lele a lele paha inā pilikia. He palahalaha a elliptical ke ano o na nymphs, aneane scaly. ʻAʻole ikaika lākou ma mua o ka poʻe mākua a ʻoi aku ka nui ma ka ʻaoʻao lalo o nā lau. He melemele ka waihoʻoluʻu o nā nimfa hou, akā e lilo i ʻōmaʻomaʻo ke oʻo.

'Ōlelo Aʻo: He monophagous nā lau, ʻo ia hoʻi, he mea hoʻokipa lākou (ʻai kēlā me kēia ʻano i hoʻokahi ʻano mea kanu).

Po'ai ola

Hoʻopau nā mākua i ka hoʻoilo ma nā māwae o nā kumu lāʻau. I ka hoʻomaka ʻana o ka pūnāwai, male lākou a hoʻomaka nā wahine e hoʻomoe i nā hua ʻalani-melemele ma nā māwae a puni nā ʻōpuʻu a ma nā lau ke wehe ʻia nā lau. Hoʻomaka ka hāʻule ma hope o 4-15 mau lā. Hele nā ​​nymphs melemele-'ōmaʻomaʻo ma waena o ʻelima instars i 2-3 mau pule ma mua o ka hiki ʻana i ka pae makua. Ma muli o ke ʻano, aia mai hoʻokahi a ʻelima mau hanauna i kēlā me kēia makahiki.

Pehea e hoʻomalu ai

1. E kāpīpī i ka ʻaila horticultural i ka hoʻomaka ʻana o ka pūnāwai e pepehi i nā pākeke a me nā hua manu.
2. ʻO nā pepeke maikaʻi e like me ka ladybugs a me ka lacewings he mau mea ʻaihue maoli o kēia pest. No nā hopena maikaʻi loa, e hoʻokuʻu i ka wā haʻahaʻa a haʻahaʻa ka pae pest.
3. Inā kiʻekiʻe ka heluna kanaka, e hoʻohana i ka pesticide kūlohelohe liʻiliʻi a me ka pōkole e hoʻokumu i ka mana, a laila e hoʻokuʻu i nā iniseti predatory e mālama i ka mana.
4. ʻAʻole loaʻa i ka honua diatomaceous nā mea ʻawaʻawa a hana wikiwiki i ka pili ʻana. E kāpīpī mālie i nā mea kanu mea kanu ma nā wahi a pau e noho ai nā mākua.
5. Hana wikiwiki ʻo Safer® insecticidal soap no nā maʻi ʻino. He pesticide maoli me ka manawa pōkole o ka hana, hana ʻo ia ma ka hoʻopōʻino ʻana i ka papa waho o nā mea ʻino kino palupalu, e hoʻoulu ai i ka wai a me ka make i loko o kekahi mau hola. Inā loaʻa nā pepeke, e hoʻopili i ka 2.5 oz/galani wai, e hana hou i kēlā me kēia 7-10 mau lā e like me ka mea e pono ai.
6. Hoʻopili ʻo WP (kaolin clay) i kahi kiʻiʻoniʻoni pale pale e hana ma ke ʻano he pale mea kanu ākea ākea e pale ai i ka pōʻino mai nā mea ʻino.
7. ʻO BotaniGard ES kahi lāʻau lāʻau lāʻau lāʻau insecticide ikaika loa Boveria Bassiana, he ha'o entomopathogenic e ho'opilikia i ka papa inoa lō'ihi o nā mea 'ai, 'o ia ho'i nā mea 'ino kū'ē! Hiki i nā noi i kēlā me kēia pule ke pale i ka pahū ʻana o ka heluna kanaka a hāʻawi i ka palekana e like a ʻoi aku ka maikaʻi ma mua o nā pesticides kemika maʻamau.
8. Ua ʻae ʻia ka ʻaila neem 70% no ka hoʻohana ʻana i nā mea ola a hiki ke hoʻopuʻi ʻia ma luna o nā mea kanu, nā lāʻau huaʻai a me nā pua e pepehi i nā hua manu, nā larvae a me nā ʻenekini makua. E hoʻohui i 1 oz/galani wai a pīpī i nā ʻili lau a pau (me nā ʻaoʻao lalo o nā lau) a pulu loa.
9. Inā ʻaʻole hiki ke ʻae ʻia ka nui o nā pest, e mālama i nā wahi i kēlā me kēia 5 a 7 mau lā me kahi insecticide i ʻae ʻia no ka hoʻohana organik. Pono ka hoʻomalu maikaʻi ʻana i ka uhi piha ʻana o ka luna a me lalo o nā lau infested.

Manaʻo kōkua: Mai hoʻomoʻo nui i nā mea momona - nā mea ʻupena e like me nā mea kanu me ke kiʻekiʻe o ka nitrogen a me ka ulu hou palupalu.
