Iinkxalabo malunga nokuvezwa kwezibulali-zinambuzane ebantwini ziye zakhuthaza ukuphuhliswa kwezinye izixhobo zokulawula iincukuthu zebhedi, kwaye kuye kwaveliswa izibulali-zinambuzane ezininzi ezisekelwe kwioyile ebalulekileyo kunye nezibulali-zinambuzane ezicoca izinambuzane kwiminyaka yakutshanje. Kodwa zisebenza njani? Ukuze bafumanise oku, abaphandi kwiYunivesithi yaseRutgers bavavanye ukusebenza kakuhle kweemveliso ezilithoba ezisekelwe kwioyile ebalulekileyo kunye nezicoci ezimbini ezibhalwe kwaye zafakwa kwimarike yokulawula iincukuthu zebhedi. Iziphumo zapapashwa kwinqaku elikwi "Journal of Economic Entomology".
Isibulali-zinambuzane esingeyomveliso sezinambuzane-sine-geraniol, ioyile yerosemary, ioyile yepeppermint, ioyile yesinamoni, ioyile yepeppermint, i-eugenol, ioyile yeclove, ioyile yelemongrass, i-sodium lauryl sulfate, i-propylene glycol 2-benzoate, i-sorbic acid Izithako ezifana ne-potassium kunye ne-sodium chloride-kuquka ezi mveliso zilandelayo:
Xa abaphandi batshiza izibulali-zinambuzane ezili-11 ezingezizo ezokwenziwa ngqo kwii-nymphs zeencukuthu zebhedi, bafumanise ukuba zimbini kuphela ii-EcoRaider (1% geraniol, 1% cedar extract kunye ne-2% sodium lauryl sulfate) kunye neBed Bug Patrol (0.003% clove oil), 1% peppermint oil kunye ne-1.3% sodium lauryl sulfate) ezibulele ngaphezulu kwama-90% azo. Ngaphandle kwe-EcoRaider eyabulala ama-87% azo, akukho ezinye izibulali-zinambuzane ezingezizo ezokwenziwa ezazinefuthe elicacileyo kumaqanda eencukuthu zebhedi.
Nangona ezi ziphumo zelebhu zibonakala zikhuthaza, ukusebenza kakuhle kwezi mveliso zimbini kusenokuba kuphantsi kakhulu kwimeko-bume yokwenyani, kuba amandla okufihla nayiphi na imveliso kwiimfanta ezincinci kunye nemingxunya kwenza kube nzima ukuyitshiza ngqo kwiincukuthu.
Ababhali babhale bathi: “Phantsi kweemeko zasemasimini, iincukuthu zifihla kwiindawo eziqhekekileyo, kwiindawo eziqhekekileyo, nakwezinye iindawo ezininzi apho kungenakwenzeka khona ukusebenzisa izibulali-zinambuzane ngqo kwizinambuzane ezifihliweyo.” “Kufuneka kwenziwe phantsi kweemeko zasemasimini. Olunye uphando lokufumanisa ukusebenza kakuhle kwe-EcoRaider kunye ne-Bed Bug Patrol kunye nendlela yokuzifaka kwiinkqubo zolawulo lweencukuthu.”
Okumangalisayo kukuba, ezinye zezithako ezisebenzayo kwi-EcoRaider kunye ne-Bed Bug Patrol nazo zivele kwezinye iimveliso ezivavanyiweyo. Ukusebenza kakuhle kwezi mveliso kuphantsi kakhulu, nto leyo ebonisa ukuba izithako ezingasebenziyo zale mveliso nazo zibalulekile.
Ababhali babhale bathi: “Ukongeza kwizithako ezisebenzayo, ezinye izinto kufuneka zibangelwe kukusebenza kakuhle kwezibulali-zinambuzane ezithile ezisekelwe kwioyile ebalulekileyo.” Ezifana nee-agents zokumanzisa, izisasazi, iziqinisi, izicoci, ii-pastes kunye nee-Adjuvants ezifana nezinyibilikisi zinokuba nefuthe elihambelanayo kwiioyile ezibalulekileyo ngokuphucula ukungena kwe-epidermis yezinambuzane kunye nokudluliselwa kwezithako ezisebenzayo kwizinambuzane.”
