Action wa biopesticide matrine ofotokoza anali imawunikidwa tizirombo anayi ulimi

The bioactivity wa biopesticide Matrine ofotokoza anali imawunikidwa ndi mitundu anayi tizilombo (Diaphorina citri, Panonychus citri, Sitophilus zeamais ndi Spodoptera frugiperda) zofunika ulimi mu njira zosiyana kupanga. Chifukwa chaichi, tinkachititsa bioassays pansi zasayansi ndi munda (ulimi malonda) zinthu. Zasayansi bioassay wathu, biopesticide Matrine ofotokoza anachititsa zotsatira woopsa ndi sublethal pa mitundu yonse anaphunzira tizilombo. Komabe, ntchito yake acaricidal ndi P. citri anali pakati ~10 ndi 100 zina kuposa zochita zake insecticidal (pa D. citri, S. zeamais ndi S. frugiperda). Mu mayesero ndi mbande kuphunzitsidwa Miphika, ntchito acaricidal wa chiphunzitso ichi unali wofanana ndi wa spirodiclofen (kulamulira zabwino). Ngakhale kugwira kwake kwambiri, biopesticide anasonyeza yochepa yotsalira zotsatira (~1 tsiku). Mu malonda zipatso famu Brazil (ndi infestation zachilengedwe a P. citri ndi Eutetranychus banksi), chiphunzitso ichi biopesticide (pa 150 ppm) anasonyeza mkulu efficacy (~90%) mu kumachepetsa anthu mite, ntchito acaricidal wofanana ndi wa spirodiclofen. Izi biopesticide Matrine ofotokoza ndi kothandiza chigawo chitetezo mbewu kumene kuphunzira mitundu tizilombo zidzachitika, makamaka mu kachitidwe zachilengedwe zakudya, amene amafunika zida imayenera kuti kasamalidwe tizilombo.
