Wake wazibona yini izimpawu ezingajwayelekile engadini noma ensimini yakho, njengokungathi othile ufike wadla amaqabunga ebusuku? Noma wake wabona izikhwebu zommbila noma zerayisi ezibunjwe kahle ziwela phansi ngokuzumayo? Ungase ucabange ukuthi lokhu kuyinto eyenzeka ngenxa yomoya onamandla. Kodwa imbangela yalokhu kungaba uhlobo olukhethekile lwesibungu esibizwa ngokuthi "i-Armyworm" ngoba sihlasela izitshalo ngokuzumayo njengebutho. Ake sixoxe ngalokhu ngemininingwane ethe xaxa namuhla.
Ubani lo mhlukumezi wezempi?
Kalula nje, i-armyworm iyisilokazane. Uma sikhuluma iqiniso, yisigaba sesibungu sento eyenzeka ebusuku, okusho ukuthi iyasebenza ebusuku, i-moth. Lawa mabhu yiwona alimaza izitshalo zethu, ikakhulukazi izitshalo zokusanhlamvu ezifana nelayisi, ummbila, namabele, kanye nezitshalo zotshani.
Lezi zibungu zibizwa ngokuthi “amabutho” ngesizathu esikhethekile kakhulu. Lapho ukudla kuphela endaweni eyodwa, izinkulungwane zalezi zibungu, njengebutho, ziyamasha bese “zihamba” ziye endaweni entsha lapho kunokudla khona. Lesi yisona sizathu esenza zathola igama lazo.
Umjikelezo wokuphila we-armyworm
Kunezigaba ezine eziyinhloko emjikelezweni wokuphila kwaleli bhungane.
1. Isigaba samaqanda: Ibhungane lesifazane libekela amakhulu amaqanda ngamaqoqo ngaphansi kwamaqabunga afana notshani. Iqembu ngalinye lingaqukatha amaqanda afinyelela ku-200. Ezinsukwini ezimbalwa, la maqanda achanyuselwa abe yizibungu.
2. Isigaba se-larva: Lesi yisigaba esibhubhisa kakhulu izitshalo. Ama-citrus amancane aphuma emaqandeni ayadla kakhulu. Akhula ngokushesha ngokudla njalo izingxenye zesitshalo njengamaqabunga nama-pod. Kunezigaba eziningana ezincane kulesi sigaba se-larva. Lezi zigaba zibizwa ngokuthi `(instar)`. Kusesigabeni sesithupha nesokugcina `(instar)` lapho cishe u-80% womonakalo owenziwe kulo lonke umjikelezo wokuphila wenziwa khona.
3. Isigaba se-pupa: Isibungu esikhule ngokugcwele sigubha ngaphansi komhlaba bese sakha i-cocoon esizungezile ukuze sibe yi-pupa. Kulesi sigaba, kwenzeka izinguquko zangaphakathi ezidingekayo ukuze sibe yi-nundu.
4. Isigaba sobudala: Ngemva kwesonto elilodwa kuya kwamathathu, kuvela ibhu elidala elimpunga noma elinsundu ebhukwini. La mabhu aqhubeka nomjikelezo ngokubeka amaqanda futhi.
Wazi kanjani ukuthi kubangelwa yizibungu?
Hlala uqaphile lezi zimpawu ukuze ubone ukuthi izitshalo zakho zonakaliswe yilesi sibungu. Ukuzibona kubaluleke kakhulu ukuze uthathe isinyathelo esisheshayo.
| Isici somonakalo | Incazelo |
|---|---|
| Izimpawu zokulimala kwamaqabunga | Amaphethelo namaphuzu amaqabunga kubonakala sengathi aqhekeziwe. Ngezinye izikhathi, kusala isisekelo seqabunga kuphela, bese kuthi okusele kudliwe. |
| Izindlebe zommbila eziwile | Izikhwebu zezitshalo ezifana nelayisi nommbila azikahlukani ngokuphelele, kodwa zilenga esihlahleni noma ziwela phansi. Lokhu kuhlukile kumonakalo obangelwa yimimoya enamandla. |
| Imfucuza ye-caterpillar | Izinhlayiya ezincane, eziluhlaza okotshani noma eziphuzi, eziyisilinda (1-2 mm) zitholakala emaqabunga noma phansi kwezihlahla. Lezi yizintuthwane zezibungu. |
| Ukubona izibungu | Emini, ungathola izibungu zicashe esiqwini sesitshalo, phakathi kwamaqabunga, noma phansi kwesihlahla. Zisebenza kakhulu ebusuku. |
Ingabe lokhu kuyingozi empilweni yethu?
Manje ungase uzibuze ukuthi lesi sibungu sinobuthi emizimbeni yethu noma sibangela izifo.
Ngenhlanhla, isibungu saseSena asiyona ingozi eqondile empilweni yabantu. Lokhu kusho ukuthi ukuthinta noma ukuthinta isibungu akuyona inkinga enkulu. Kodwa-ke, kunemiphumela eminingana engaqondile yezempilo kanye nezomnotho .
- Ukusetshenziswa kwezibulala-zinambuzane: Abalimi nabalimi basebenzisa izibulala-zinambuzane ukulawula lesi sinambuzane. Uma lezi zingasetshenziswa ngendlela efanele nangokuphephile , amakhemikhali aqukethwe yizo angangena emzimbeni. Lokhu kungabangela izinkinga ezahlukene zempilo.
- Ukulahlekelwa ngokwezomnotho: Lokhu ukulahlekelwa okukhulu ngokwezomnotho kubalimi. Isivuno esilinywe ngezindleko ezinkulu singabhujiswa ezinsukwini ezimbalwa. Ukucindezeleka kwengqondo okubangelwa yilokhu nakho akubalulekile.
Kubaluleke kakhulu: Uma izibulala-zinambuzane zisetshenziswa ngendlela engafanele noma zigwinywe ngephutha, zingabangela ubuthi. Uma lokhu kwenzeka kuwe noma komunye umuntu, hamba uye eMnyangweni Wezimo Eziphuthumayo wesibhedlela esiseduze (i-ETU) ngokushesha . Uma udinga ulwazi olwengeziwe noma iseluleko mayelana nalokhu, ungashayela i-National Poisons Information Centre e-Colombo National Hospital .
Lolu songo lungalawulwa kanjani?
Ukulawula ukutheleleka kwezibungu kuyinselele, kodwa isinyathelo sokuqala singanciphisa umonakalo.
1. Thola futhi uqaphe ngokushesha
Hlola isivuno njalo, ikakhulukazi ekuseni nakusihlwa. Bheka izimpawu zomonakalo okukhulunywe ngazo ngenhla. Qaphela izibungu namaqoqo amaqanda.
2. Izindlela zokulawula zemvelo
Uma umonakalo mncane, ungasusa izibungu ngesandla. Kungumqondo omuhle futhi ukudala indawo ekhuthaza izitha zemvelo zezibungu, njengezinyoni nezinye izinambuzane, ukuthi zivakashele isivuno.
3. Ukusetshenziswa kwezibulala-zinambuzane
Uma ukutheleleka kungalawuleki, kungadingeka usebenzise izibulala-zinambuzane. Kukhona izibulala-zinambuzane ze-organic (njenge-`(Bacillus thuringiensis)`, `(spinosad)`) kanye ne-chemical (njenge-`(deltamethrin)`, `(bifenthrin)`).
Isexwayiso: Ngaphambi kokukhetha nokusebenzisa isibulala-zinambuzane, hlala uthintana nesikhulu sezolimo noma isikhulu sendawo. Sebenzisa uhlobo kanye nenani abalincomayo kuphela, bese ulandela izinqubo zokuphepha ezifanele (njengokugqoka imaski yobuso namagilavu). Ungalokothi usebenzise izibulala-zinambuzane ngokubona kwakho.
4. Ukulawula ukhula
Gcina indawo elinyiwe nezindawo ezizungezile zingenalo ukhula, ikakhulukazi utshani, njengoba lezi yizindawo lapho amabhungane ethanda ukubeka amaqanda awo khona. Ukususa ukhula kunganciphisa ukubekela amaqanda.
Umlayezo Wokuya Nawe Ekhaya
- I-armyworm iyisigaba se-butber se-moth. Yilesi sibutberber esonakalisa izitshalo.
- Izimpawu eziyinhloko zalo monakalo amaqabunga aphukile, ama-pod awile, kanye nemfucumfucu yama-caterpillar.
- Ukutholwa kusenesikhathi kubaluleke kakhulu ekulawuleni izinambuzane. Qapha izitshalo zakho njalo.
- Nakuba lezi zibungu zingabangeli usongo oluqondile empilweni yabantu, ukusetshenziswa kabi kwezibulala-zinambuzane ezisetshenziswa ukuzilawula kuyingozi empilweni.
- Hlala ufuna iseluleko sochwepheshe bezolimo ngaphambi kokusebenzisa izibulala-zinambuzane bese ulandela imikhuba yokuphepha enconyiwe.
- Uma kwenzeka isimo esiphuthumayo sezempilo esihlobene nezibulala-zinambuzane, bona udokotela wakho ngokushesha noma uye esibhedlela i -ETU esiseduze.
