Faatinoga o se matrine faavae biopesticide na iloiloina e faasaga i meaola faalafua faatoaga fa

O le bioactivity o se biopesticide Matrine faavae na iloiloina e faasaga i le fa ituaiga o meaola faalafua (Diaphorina citri, Panonychus citri, Sitophilus zeamais ma Spodoptera frugiperda) o taua faatoaga i faiga eseese o le gaosiga. Mo lenei faamoemoe, tatou te faia bioassays i lalo o fale suesue ma fanua (faatoaga faapisinisi) tuutuuga. I o tatou bioassay fale suesue, o le mafua biopesticide faale-Matrine aafiaga matautia ma sublethal i luga o ituaiga meaola faalafua suesue uma. Ae peitai, sa ana gaoioiga acaricidal faasaga i P. citri va ~10 ma le 100 taimi sili atu nai lo ana gaoioiga insecticidal (i D. citri, S. zeamais ma S. frugiperda). I le suega i fatu laau atiina ae i vases, sa faapena le gaoioiga acaricidal o lenei tuufaatasia i lena o spirodiclofen (o le pulea lelei). E ui lava i lona aoga maualuga, na faaalia e le biopesticide se aafiaga residual puupuu (~1 aso). I se faatoaga citrus faapisinisi i Pasila (faatasi ai ma infestation masani o P. citri ma Eutetranychus banksi), o lenei tuufaatasia biopesticide (i le 150 ppm) Na faaalia aoga maualuga (~90%) i faaitiitia le faitau aofai tupe iti, ma acaricidal gaoioiga faapena i lena o spirodiclofen. O lenei biopesticide Matrine-faavae o se vaega aoga mo le puipuiga o laau toto pe afai o le suesueina meaola faalafua tupu, e matele i le faiga ecological o le gaosiga o meaai, lea e manaomia le fesoasoani o meafaigaluega lelei mo le puleaina faalafua.
