Masayendisiti anobva kuCabi, iyo University of Wagkuva Institute, pamwe neyekutungamira munhoroondo yesainzi pest
Zviwanikwa zvavo zvinounza nhau dzakanaka dzezvematongerwo enyika dzekubereka, nekuti mhedzisiro inoratidza mukana wekuwedzera huwandu hwevanhu vechisikigo chevavengi vechiitiko (autumn honline). Uye nokudaro, kune nzira dzakachengeteka uye dzinoshanda dzekurwisa zvipembenene izvo varimi vadiki vanogona kushandisa pazvirimwa zvavo.
Vavengi vemamwe marudzi anowanzo kusvika mumamiriro ezvinhu matsva pasina vavengi vechisikigo pasina vavengi vepanyama uye, nekukasira kusununguka, vachigadzira kutyisidzira varimi varimi munyika dzakaderera.
Contious Corn Scoop, kutinhira kwenhamburiko kuchamhembe neSouth America, vakasvika muAfrica muna 2016 uye kwakaita kuti vakakonzera kukuvara kwakanyanya uye dzimwe tsika munzvimbo dzese. Semuenzaniso, varimi vechibage vakarasikirwa avhareji ye25.6% kukohwa kuGhana ne 35% muZambia nekuda kweiyi pest.
Ndokusaka nzwisiso ye biocontrol yakakosha. Kune izvi, boka revatsvagiri pasi pehutungamiri hweCabi rakabata basa kuitira kuti vaone maParasitoids yemuno vachirwisa "vhezheni" muZambia. Vakamhanya mazai uye mabara anopisa munguva yechibage chechienda mumwaka wekunaya wa 2018-2019 munzvimbo ina muLusaka nedunhu repakati reZambia kuti uwane parasittoids.
Muzvakazara, makumi mana nemakumi mana nemakumi mana nemakumi mana nenomwe. Kune imwe neimwe saiti uye zuva rekukohwa, mareti ekukohwa akanyorwa, huwandu hwezvirimwa zvinoratidzwa uye huwandu hwekukuvara kuongorora kuti ndezvipi zvinhu zvakanyatsotsanangura kutaridzika kwevavengi vechisikigo pane chibage. Masayendisiti akawana kuti mune general level yerarism kubva kune yemuno vavengi munzvimbo imwe neimwe inosiyana kubva 8.45% kusvika 33.11%.
Vakazvizivisa gumi nemaviri akasiyana emhando dzeparasitoids uye zvinhu zvinokanganisa kutaridzika kweparasitoids. Nekuda kweizvozvo, 4 zvakakosha zvikamu zvakapihwa:
- Nzvimbo yenzvimbo
- Chikamu chekukura chezviyo,
- Pest Darnity
- Lichwater Stage.
Kuwanikwa kusingatarisirwi kwaive shanduko muchiitiko cheparasitoids panguva yeiyo chibage chekuwedzera kutenderera. Munguva yematanho ekupedzisira ezviyo kuiera (11-12 mashizha, achisiya uye arikumonera), kuitika uye huwandu hweparasitoids inoderera.
Chidzidzo ichi chinoratidza kukosha kwekunzwisisa zvinhu nenzvimbo nekuda kwekugadzwa kwevavengi vepanyama. Zvinonyanya kuitika pakushandiswa kwekutonga kwezvinhu uye nekuvandudza kwenzira dzekurwisa nguva dzakananga dzezviputa kuitira kuti uwedzere kuwanda kwechikepe muAfrica nharaunda dzekurima muAfrica.
Tsvagurudzo inotevera ikozvino inodiwa kuti uone mhando yerudzi rwechokwadi, uye morphological neyekuzivikanwa, zvisinei, nhanho yekutanga uye yakakosha pakurwa neyenzvimbo ine njodzi zvakanyanya kutyisidzira ramangwana revarimi veAfrica.
