I-BEET BUG (i-Piesmaquadratum) iyisiphazamiso esingaba ngu-3 mm ubude, sishintshashintsha kakhulu ngombala. Imvamisa iba mpunga ngokumnyama kanye nephethini elimnyama. Amehlo abomvu. I-pronotum inezimbambo ezintathu ze-longitudinal. Izinambuzane ezindala zidlula ubusika emaphethelweni amahlathi, izihlahla, imisele, njll. Entwasahlobo, emazingeni okushisa angaphezu kuka-3 degrees C, zindiza ku-beet, lapho zimisa khona emaphethelweni ensimu. Ngemva kwesikhathi sokudla, abesifazane bazalela amaqanda (cishe amaqanda angu-15 iqabunga ngalinye lebhitrudi). Izibungu zivela phakathi noJuni. Izinambuzane ezindala zifuduka ziyolala ebusika noma ziqale ukuthuthukiswa kwesizukulwane sesibili. Isizukulwane esisodwa siyakhula ngesizini ngayinye.
Izimpawu
Izibungu kanye nezinambuzane ezindala zibhoboza amaqabunga bese zimunca ubisi, okubangela ukuguquguquka kombala kanye nokukhula kwezitshalo buthaka. Umonakalo omkhulu ukuthi isinambuzane esikhulile sisakaza igciwane le-curl yeqabunga. Izitshalo ezinegciwane ziba nokukhubazeka futhi zithathe isimo sekhanda le-ulethisi. Ukulahlekelwa ngenxa yalokhu kungaba okukhulu.
Izitshalo zokusingatha
Ngokuyisisekelo izinhlobo eziningi nezinhlobonhlobo zama-beet.
Izindlela zokulawula
Ukulawulwa kwamakhemikhali kuyatuswa ezindaweni lapho kutholwe khona izikelemu ngonyaka odlule. Le nqubo isayinwa lapho izinambuzane ezindala zingena endaweni yokutshala futhi zifutha izitshalo ze-beet.
