Mwa zinthu zolembetsedwa, zisanu zili ndi zosakaniza zogwira ntchito zomwe zafika ku Brazil koyamba, zitatu zili ndi zosakaniza zogwira ntchito zomwe zingagwiritsidwe ntchito mu ulimi wachilengedwe ndipo ziwiri zili ndi zosakaniza zogwira ntchito zomwe zimachokera ku mankhwala.
Zinthu zitatu zatsopano zamoyo (Neoseiulus barkeri, S. chinensis, ndi N. montane) zalembedwa pansi pa Reference Specification (RE) ndipo zitha kugwiritsidwa ntchito mu njira iliyonse yobzala.
Neoseiulus barkeri ndiye mankhwala oyamba kulembedwa ku Brazil kuti athetse Raoiella indica, tizilombo toopsa kwambiri ku mitengo ya kokonati. Mankhwala omwewo ozikidwa pa kulembetsa kwa ER 45 angalimbikitsidwenso kuti athetse tizilombo toyera.
Bruno Breitenbach, wogwirizanitsa wamkulu wa mankhwala ophera tizilombo ndi zinthu zina zokhudzana nazo, anafotokoza kuti: “Ngakhale kuti tili ndi mankhwala ophera tizilombo tomwe tingasankhe, ichi ndi chinthu choyamba chamoyo chophera tizilombo.”
Mavu a parasitic a Hua Glazed Wasp anakhala chinthu choyamba chamoyo kutengera kulembetsa kwa ER 44. Asanayambe izi, alimi anali ndi mankhwala amodzi okha omwe angagwiritsidwe ntchito poletsa Liriomyza sativae (Liriomyza sativae).
Kutengera ndi Malamulo Oyendetsera Nambala 46, mankhwala olembetsedwa oletsa tizilombo toyambitsa matenda otchedwa Neoseiia mountain mite akulimbikitsidwa kuti athetse matenda a Tetranychus urticae (Tetranychus urticae). Ngakhale pali mankhwala ena achilengedwe omwe angathenso kuletsa tizilombo toyambitsa matenda, mankhwalawa ndi njira ina yosawononga kwambiri.
Chosakaniza chatsopano chogwiritsidwa ntchito ndi mankhwala ndicyclobromoximamidePofuna kulamulira mbozi za Helicoverpa armigera mu mbewu za thonje, chimanga ndi soya. Mankhwalawa amagwiritsidwanso ntchito poletsa Leucoptera coffeella mu mbewu za khofi ndi Neoleucinodes elegantalis ndi Tuta Absolute mu mbewu za phwetekere.
Chosakaniza china chatsopano chogwiritsidwa ntchito ndi mankhwala ophera fungicideisofetamid, imagwiritsidwa ntchito poletsa matenda a Sclerotinia sclerotiorum mu mbewu za soya, nyemba, mbatata, phwetekere ndi letesi. Mankhwalawa amalimbikitsidwanso poletsa matenda a Botrytis cinerea mu anyezi ndi mphesa ndi Venturia inaequalis mu mbewu za apulo.
Zinthu zina zimagwiritsa ntchito zosakaniza zomwe zalembetsedwa ku China. Kulembetsa mankhwala ophera tizilombo ndikofunikira kwambiri kuti muchepetse kuchuluka kwa anthu pamsika ndikulimbikitsa mpikisano, zomwe zimabweretsa mwayi wochita malonda wabwino komanso ndalama zochepa zopangira ulimi waku Brazil.
Zinthu zonse zolembetsedwa zimasanthulidwa ndikuvomerezedwa ndi madipatimenti omwe ali ndi udindo pa zaumoyo, chilengedwe ndi ulimi mogwirizana ndi miyezo yasayansi komanso machitidwe abwino apadziko lonse lapansi.
