1.Avermectin imakhala ndi poizoni wa m'mimba ndi kukhudza-kupha mphamvu pa nthata ndi tizilombo, ndipo sangathe kupha mazira.Limagwirira ntchito ndi wosiyana ndi mankhwala ambiri tizilombo chifukwa zimasokoneza ntchito neurophysiological ndi kumapangitsa kuti amasulidwe γ-aminobutyric asidi, amene ali chopinga kwenikweni pa mitsempha conduction mu arthropods.Akuluakulu a nsabwe, nyongolotsi ndi mphutsi za tizilombo zimasonyeza zizindikiro zakufa pambuyo pokhudzana ndi avermectin, ndipo sizisuntha kapena kudyetsa, ndipo zimafa patatha masiku awiri kapena anayi.Chifukwa sichimayambitsa kutaya madzi m'thupi mwachangu kwa tizilombo, kupha kwa abamectin kumachedwa.Ngakhale avermectin Chemicalbook imakhudza mwachindunji tizilombo tolusa komanso adani achilengedwe a parasitic, ilibe kuwonongeka pang'ono kwa tizilombo topindulitsa chifukwa pamakhala zotsalira pang'ono pamtunda.Abamectin samasunthidwa ndi kutengeka kwa dothi ndikuwola ndi tizilombo tating'onoting'ono m'nthaka, chifukwa chake alibe zotsatira zochulukirapo m'chilengedwe ndipo angagwiritsidwe ntchito ngati gawo lofunikira pakuwongolera kophatikizika.Ndizosavuta kukonzekera ndipo zingagwiritsidwe ntchito potsanulira kukonzekera m'madzi ndikugwedeza pang'ono.Ndiwotetezeka ku mbewu ndipo palibe kuwonongeka komwe kudzachitike mukagwiritsidwa ntchito molingana ndi njira yomwe idakhazikitsidwa.Mbewu zogwiritsidwa ntchito: masamba, citrus, thonje, etc
2.Avermectin ndi kalasi ya macrolide omwe ali ndi magawo khumi ndi asanu ndi limodzi omwe ali ndi tizilombo toyambitsa matenda, acaricidal ndi nematicidal zomwe zinayamba kupangidwa ndi Tomo Omura et al.ya Kitasato University, Japan ndi Merck, USA, ndipo yopangidwa ndi fermentation ya Streptomyces avermitilis mu Streptomyces griseus.Natural abamectin ili ndi zigawo 8, makamaka 4 zomwe ndi A1a, A2a, B1a ndi B2a, zomwe zili ndi ≥ 80%;ogwirizana 4 omwe ali ndi magawo ang'onoang'ono ndi A1bChemicalbook, A2b, B1b ndi B2b, omwe ali ndi ≤ 20%.Panopa malonda avermectin mankhwala ndi abamectin monga waukulu insecticidal chigawo chimodzi (AvermectinB1a + B1b, amene B1a si zosakwana 90%, B1b si upambana 5%), kuti zili B1a kuti calibrate.Kuyambira 1991, kupha tizirombo (abamectin) pamsika waku China wophera tizilombo, mankhwala ophera tizilombo ku China ali ndi udindo wofunikira kwambiri.
