Chikumbu cha Njovu: Chilombo choopsa chokhala ndi mphuno zazitali
Zikumbu zambiri zimawononga ulimi. Mmodzi wa iwo ndi banja la zikumbu, zomwe zimatchedwanso njovu, chifukwa cha proboscis zawo zazitali.

Chodziwika bwino ndi chubu chomwe chimachokera kutsogolo kwa mutu. Iwo, nawonso, amagawidwa mu mitundu iwiri malinga ndi mawonekedwe a chiwalo:
- ma proboscis amfupi omwe amamera m'nthaka;
- ma proboscis aatali, omwe amamera m'magulu a zomera.
Maonekedwe ndi mthunzi wa thupi zimatengera mtundu wake. kachilomboka. Amakhala atali, ozungulira, ozungulira kapena oblong. Kukula kumasiyanasiyana kuchokera 30 mpaka 50 mm. Mithunzi ikhoza kukhala:
- yellow;
- zofiirira;
- wakuda;
- wofiira-bulauni;
- mkuwa;
- wobiriwira.
Nthawi zina thupi limatha kukwiririka ndi tsitsi, mamba, bristles, ngakhale chowoneka ngati kutumphuka.
Mapangidwe a akuluakulu
Onse oimira banja la njovu ali ndi dongosolo lomwelo.
Nthawi zambiri imakhala yozungulira, rostrum imakhala yosiyana mosiyanasiyana komanso kutalika kwake. Maso ndi ang'onoang'ono, omwe ali m'mbali. Mwa anthu ena amachepetsedwa. Nsagwada zapakamwa zimakhala zosavuta.
Scutellum imawoneka, mawonekedwe a prescutum amatha kukhala osiyanasiyana, ozungulira kapena ozungulira. Mimba imakhala ndi magawo asanu, ma sternites, omwe pamwamba pake amatha kukhala osiyana, kukhala amaliseche kapena okutidwa ndi tsitsi.
Ma elytra nthawi zambiri amakhala aatali, otambalala. Mwa anthu ena, amatha kukulira limodzi motsatira msoko ndi metathorax. Kukhalapo ndi mtundu wa mapiko kumadalira mwachindunji mtundu wa kachilomboka.
Miyendo ya kafadala imatha kukhala yayitali kapena yayifupi. Malingana ndi mitundu, amatha kukhala ndi tsitsi kapena miyendo yotambasula, kuti azitha kusambira bwino kapena kupalasa.
Nthawi zambiri zooneka ngati chikwakwa, zoyera kapena zachikasu mu mtundu, yokutidwa ndi pincers kapena tsitsi. Mutu umasonyezedwa momveka bwino, wozungulira mawonekedwe.
Zokonda zakudya
Pakati pa nyuzi pali oimira osiyanasiyana. Malinga ndi chikhalidwe cha zakudya, iwo akhoza kukhala:
- monophages;
- oligophages;
- polyphages.
Mitundu ya tizirombo ta zomera
Oimira ena a weevils angagwiritse ntchito mtundu umodzi wokha wa zomera kapena oimira banja limodzi, koma palinso ma polyphages osasamala.
Momwe mungathanirane ndi weevil
Njira yolimbana ndi kachilomboka imatha kukhala nkhondo yokhazikika komanso yayitali ngati njira zoteteza mbewu sizinayambike masika. Mtundu uliwonse umafunikira njira yoyenera, koma pali malamulo ambiri othana ndi kachilomboka.
Pali njira zingapo zotsimikiziridwa:
- Zimango. Uku ndi kusonkhanitsa kwamanja, kugwedeza, kukumba.
- Zomera ntchito. Izi zikuphatikizapo kuyeretsa zinyalala ndi zovunda, kuchotsa mbali zowonongeka, kuyeretsa makungwa, kuyeretsa mitengo.
Chikumbu cha Njovu.
- Chitetezo chokhazikika. Mutha kukopa mbalame kupita kumalo omwe amadya mbozi ndi mbozi. Gwiritsani ntchito malamba pamitengo.
- njira za anthu. Izi ndi infusions zosiyanasiyana ndi decoctions zomera chiyambi. Iwo ali ndi insecticidal zotsatira.
- Mankhwala. Izi ndi zida zankhondo zolemera, zomwe zimagwiritsidwa ntchito pa matenda ambiri. Pamafunika kulondola komanso kusamala.
Tsatirani ulalo kuti mudziwe zambiri za momwe mungamenyere. ndi nyuzi.
Njira zothandizira
Zachidziwikire, kupewa sikungatsimikizire kuti kachilomboka sikadzawonekera pamalowo. Koma chiwerengero cha weevils chikhoza kuchepetsedwa kwambiri ngati mutatsatira malamulo osavuta.
- sungani ukadaulo waulimi, malamulo osamalira;
Chikumbu.
- sankhani oyandikana nawo oyenera;
- kudulira, kukumba, kulima m'minda;
- chotsani zovunda ndi zinyalala;
- kudyetsa panthawi yake ndikuwunika thanzi la mbewu;
- kuchita njira kasupe kupopera mbewu mankhwalawa.
Kodi nsikidzi ndi zothandiza?
Kambuku ndi adani a ulimi omwe amawononga zomera zomwe zimabzalidwa. Koma pakati pawo pali zamoyo zomwe zimadya udzu basi. Njira yokayikitsa yoteteza munda ku tizirombo, koma ndi gawo lofunikira la biocenosis.
Pomaliza
Kambuku ndi banja lalikulu lomwe ndi tizirombo taulimi, tchire la zipatso, mitengo ya zipatso ndi mbewu za mabulosi. Amadziwika ndi chilakolako chawo ndipo amatha kuvulaza mbali zosiyanasiyana za zomera.
