Kweli nqaku, uZsofia Sendre weSebe le-Entomology kwiYunivesithi yaseMichigan State ubhala ukuba le ntsholongwane intshaizibulali-zinambuzane zilawula ngempumeleloiColorado potato beetle kunye nezinye izinambuzane ezininzi zetapile, nto leyo enika abalimi isixhobo esitsha esixabisekileyo sokufaka kwiinkqubo zabo zokulawula ukumelana nezibulali-zinambuzane.
I-Colorado potato beetle isesesinye sezona zinambuzane zinengxaki kakhulu kwiitapile. Abalimi ngoku banokusebenzisa i-Zivalgo (i-fiazolin, iteknoloji ye-prazoline), isibulali-zinambuzane esitsha samagqabi esibonelela ngesixhobo esitsha esibalulekileyo sokulawula i-Colorado potato beetle.
I-Zivalgo sisibulali-zinambuzane seKlasi lama-30, oko kuthetha ukuba indlela esebenza ngayo yahlukile kwezinye izibulali-zinambuzane ezivunyiweyo ngoku ukulawula i-Colorado potato beetle. Ngenxa yokuba i-Colorado potato beetle sele ikhulele ekumelaneni nezibulali-zinambuzane ixesha elide, ukongeza indlela entsha yokusebenza kubalulekile ekulawuleni ukuxhathisa. Ukutshintshatshintsha iindidi ezahlukeneyo zezibulali-zinambuzane ngexesha lokukhula kunceda ukugcina ukusebenza kweemveliso ezikhoyo.
I-Zivalgo isebenza kakuhle kuzo zonke izigaba zeColorado potato beetle kwaye ingafakwa kulo lonke ixesha lokukhula, iqala kwiintsuku ezili-14 ngaphambi kokuvuna. Nangona kunjalo, emasimini apho kwakusetyenziswa khona izibulali-zinambuzane ngexesha lokutyala ukulawula ii-overwintering beetle, i-Zivalgo isetyenziswa kakhulu ukulawula ukuvela kwabantu abadala ehlotyeni, okuhlala kuqala ekuqaleni kukaJulayi kwiindawo ezininzi zaseMichigan.
Ukuze ukhusele le khemikhali intsha kwaye ucothise ukukhula kokumelana, kuphephe ukusebenzisa iZivalgo kwiintyatyambo ezikhula ixesha elide ebusika nakwizityalo ezikhulileyo zasehlotyeni ngexesha elinye.
