Ndeyerudzi rweLepidoptera nemhuri yeNoctidae. Ndiyo mbuyu huru panguva yekukura kwedonje neboll. Makonye aya anokuvadza misoro yakapfava, maruva, neboll dzegirini dzedonje, uye anogona kuruma pamusoro pehunde pfupi dzakapfava, zvichiita donje risina misoro. Mushure mekunge nhunzi diki yakuvara, mabracts anoshanduka kuita yero uye ovhurika, odonha mushure memazuva maviri kana matatu. Makonye anofarira kudya mukume uye kusvibiswa. Mushure mekukuvadzwa, mboro dzegirini dzinogona kuita mavanga akaora kana akaomarara, zvichikanganisa zvakanyanya goho redonje uye mhando yaro.
Kudzivirira uye kudzora makemikari:
Donje rinodzivirira zvipembenene rine simba rakanaka rekudzora gonye rechizvarwa chechipiri, uye kazhinji haridi kudzorwa. Simba rekudzora gonye rechizvarwa chechitatu nechechina rinodzikira, uye kudzora kwacho nenguva kunodiwa. Mushonga unogona kuva 35% propafenone • phoxim ka1000-1500, 52.25% chlorpyrifos • chlorpyrifos ka1000-1500, uye 20% chlorpyrifos • chlorpyrifos ka1000-1500.
Spodoptera litura
Zviratidzo zvekukuvara:
Makonye achangobva kuchekwa anoungana pamwe chete odya mesophyll, achisiya tsinga dzepamusoro dzeganda kana kuti mitsipa, zvichiita sesefu yakaita seruva nemashizha. Anobva apararira okuvadza mashizha nemabukira nemashizha, odya mashizha zvakanyanya uye okuvadza bukira nemashizha, zvichiita kuti aore kana kudonha. Kana achikuvadza mabukira edonje, pane maburi 1-3 pasi pebukira, ane maburi asina kurongeka uye akakura, uye tsvina huru yezvipembenene yakaunganidzwa kunze kwemaburi.
Kudzivirira uye kudzora makemikari:
Mishonga inofanira kupiwa panguva yekutanga kwemakonye uye kudzimwa usati wadya zvakanyanya. Sezvo makonye asingabude masikati, kupfapfaidza kunofanira kuitwa manheru. Mushonga wacho unofanira kuva 35% probromine • phoxim ka1000-1500, 52.25% chlorpyrifos • cyanogen chloride ka1000-1500, 20% chlorbell • chlorpyrifos ka1000-1500, uye kupfapfaidzwa zvakaenzana.
