Izibungu eziyingozi ze-Colorado potato beetle
I-Colorado potato beetle endala inzima kakhulu ukudideka nanoma yisiphi esinye isinambuzane. I-elytra yayo enemigqa egqamile ijwayelekile kubo bonke abahlala ehlobo kanye nomlimi. Kodwa izibungu zalesi zinambuzane zingafana kakhulu neziphungumangathi zesinye isiphazamisi esiwusizo, kodwa ngesikhathi esifanayo, ezinye zazo zizuzisa kakhulu izitshalo ezikusayithi, kanti ezinye zidala umonakalo omkhulu.
Okuqukethwe
Zibukeka kanjani izibungu ze-Colorado potato beetle?
I-Larva ye-Colorado potato beetle.
Izibungu zesilokazane esinemigqa mikhudlwana kunezindala. Ubude bomzimba wabo bungafinyelela ku-1,5-1,6 cm. Ezinhlangothini zomzimba wesibungu kunemigqa emibili yamachashazi amnyama ayindilinga. Ikhanda lesibungu lipendwe ngombala omnyama, futhi umbala womzimba uyashintsha lapho ukhula.
Izibungu ezincane kunazo zonke zidwetshwe ngombala omnyama, onsundu, futhi eduze ne-pupation zithola umbala opinki okhanyayo noma obomvu-wolintshi. Lokhu kungenxa yokuthi ngesikhathi sokudla izingxenye eziluhlaza zamazambane, i-pigment carotene inqwabelana emzimbeni wabo, engcolisa izibungu ngombala ogqamile.
Umjikelezo wokuthuthukiswa kwezibungu
Ukubonakala kwezibungu emhlabeni kwenzeka cishe amasonto angu-1-2 ngemva kokuba amaqanda ebekwe. Yonke inqubo yokuvuthwa kwezibungu ihlukaniswe ngezigaba ezi-4, phakathi kwazo lapho kwenzeka khona i-molting.
Izigaba zokuthuthukiswa kwe-Colorado potato beetle.
Izibungu ze-instars yokuqala neyesibili ngokuvamile azihambi phakathi kwezitshalo futhi zihlala ngamaqembu amancane. Ukudla kwabo kuqukethe izingxenye ezithambile zamaqabunga kuphela, ngoba azikakwazi ukubhekana nemithambo eqinile neziqu.
Abantu abadala besigaba sesi-3 nesi-4 baqala ukudla kakhulu futhi badle ngisho nezingxenye eziqinile zezitshalo. Kulezi zigaba, izibungu ziqala ukuhamba ngenkuthalo esitshalweni futhi zingaya nasezihlahleni ezingomakhelwane ziyofuna ukudla.
Ngemva kokuba izibungu seziqongelele imisoco eyanele, zimba ngaphansi komhlaba ukuze zithole izibungu. Ngokwesilinganiso, isikhathi sokuphila sezibungu ze-Colorado potato beetle, kusukela ngesikhathi sokuchanyuselwa kusuka eqandeni kuya ekukhuleni, yizinsuku eziyi-15-20.
Ukudla kwe-Colorado beetle izibungu
Izibungu namaqanda e-Colorado potato beetle.
Izibungu ze-Colorado potato beetle zidla izitshalo ezifanayo nezabadala. Ukudla kwabo kuqukethe izitshalo ezifana nalezi:
- amazambane;
- utamatisi;
- isitshalo seqanda
- Upelepele waseBulgaria;
- ezinye izitshalo ezivela emndenini we-nightshade.
Intsha ingaba yingozi kakhulu kunabantu abadala. Lokhu kungenxa yokulungiswa kwezibungu zokuzala, ngoba phakathi nalesi sikhathi izinambuzane zizama ukuqongelela inani eliphezulu lezakhamzimba.
Izindlela zokubhekana nezibungu ze-Colorado potato beetle
Cishe zonke izindlela zokubhekana ne-Colorado potato beetle zihloselwe ukubhujiswa kokubili abantu abadala kanye nezibungu. Ngesikhathi esifanayo, kulula ukubhekana nokugcina. Izibungu kulula ukuzisusa ngenxa yokungakwazi ukundiza nokuba sengozini enkulu ezitheni zemvelo.
Izindlela ezidume kakhulu zokubhubhisa izibungu ze-Colorado potato beetle yilezi:
- ukuqoqwa kwezinambuzane ngesandla;
- ukufafaza ngama-insecticides;
- ukucubungula amakhambi esintu;
- ukukhangwa indawo yezilwane ezidla izibungu ze "colorados".
Ukufana kwe-larva ye-Colorado potato beetle kanye ne-pupa ye-ladybug
I-Colorado larva kanye ne-ladybug.
Naphezu kweqiniso lokuthi lezi yizinhlobo ezimbili ezihluke ngokuphelele zezinambuzane ezisezigabeni ezihlukene zokukhula, zivame ukudideka komunye nomunye. Ubukhulu bazo, ukwakheka komzimba nombala kufana kakhulu futhi umehluko ubonakala kuphela lapho uhlolisisa.
Ikhono lokuhlukanisa izinambuzane "ku-solar bug" kubaluleke kakhulu kubanikazi bomhlaba. Ngokungafani ne-Colorado potato beetle, i-ladybug iletha izinzuzo ezinkulu - ibhubhisa i-aphid, nayo eyizinambuzane eziyingozi.
Ungakwazi ukubona i-pupa yesinambuzane esiwusizo ngezimpawu ezilandelayo:
- ngokungafani nesibungu, isiphungumangathi asinyakazi;
- amabala emzimbeni we-pupa atholakala ngokungahleliwe kuwo wonke umzimba futhi apendwe ngemibala ehlukene;
- ama-ladybug pupae ahlala enamathele ngokuqinile ebusweni besitshalo.
isiphetho
Abalimi abafuna ukutshala amazambane esizeni sabo kufanele bazi isitha sabo "ngokubona" futhi bazi kangcono "amaColorado" amancane. Azizona izinambuzane eziyingozi kunabantu abadala, futhi ukuba khona kwazo esizeni kungabangela umonakalo omkhulu ezitshalweni.
