Izazi ze-EntoMologists ezivela e-University of Grand Durados eBrazil zithole ukuthi abakhangeyo obunelungelo lobunikazi lapho bexutshwe namanani amancane ezinambuzane, ngcono kakhulu ukulwa ne-corn decival scoop.
Lokhu kunciphise umonakalo odalwe ukuhlwanyela ummbila kuwo wonke amasayithi ayisishiyagalombili wokuhlola eMata Grosu-Du-Sul, esifundeni sezolimo Serrado eBrazil.
Ukulwa nokulwa ne-corn decigal scoop (Spodoptera Frugiperda) kuya ngokuya kunzima ngenxa yokwanda kokuzinza komuntu ngamunye kwezitsha kanye nezitshalo eziguqulwa ngofuzo ze-bacillus thindiliensis (BT).
Kulolu cwaningo, indlela ephelele yahlolwa ngokufafaza izinambuzane ezihehayo ze-Noctovi ®c Metomyl.
Izivivinyo zenziwa emasimini ommbila wezentengiselwano, emasikweni angenayo i-BT ne-BT, phakathi neminyaka emibili yezolimo (2018 no-2019) ngamasayithi ayisishiyagalombili asatshalaliswa emadolobheni amathathu aseningizimu ye-matu, eBrazil.
Kwasetshenziswa ukwelashwa okulandelayo kwezinambuzane: ukufafaza imivimbo eqhubekayo njalo ngonyaka 100, 50 no-25 m; Ukufafaza ngezikhathi ezithile njalo ngama-25 m; ukulawula (ngaphandle kokusebenzisa izinambuzane); nokufafaza yonke indawo yezinambuzane (ukulawula okuhle).
Ukudla kuhlazisa ne-molecule yezinambuzane kwafakwa esigcawini ezigabeni zezitshalo v1 ne-v3, kanti usayizi wabantu abadala walinganiselwa kanye nezinga lomonakalo emaqabungeni abangelwa amacimbi.
Ukusetshenziswa kwe-Peason Bait nge-strips ngesikhawu esingaphansi noma okulingana no-50 m kuncishiswe kakhulu iphesenti lomonakalo ezitshalweni, futhi umphumela waba namandla ezitshalweni BT.
Ososayensi bakholelwa ukuthi ukulawulwa kwabantu abadala be-corn scoop kungahle kube ngcono uma izindlela zokuheha nokubhubhisa zifaka ezinhlotsheni eziphelele zokulawula izinambuzane, ukuze zinciphise izinambuzane ngokuvunwa kwesibili kwe-90%.
Umhembe uhlinzekwe yinkampani yezemvelo ye-Agrotechnical Isca, Inc., i-United States, ethuthukisa isizukulwane esisha sabasebenza izinambuzane bezolimo, besebenzisa amanye ama-pheromones nezinye izinto ezihlangene ezitholakele ngokwemvelo yizitshalo nezilwane lokho khohlisa ukusebenza kwezinhlobo zezinambuzane ezihlosiwe.
I-ISCA ithuthukise futhi yenza lo mkhiqizo we-noctovi ukusabalalisa u-Exp eBrazil.
