Abstract

Total 31 samples from 21 African plant species in 13 families were tested for their insecticidal and acaricidal activities against Nilaparvata lugens (Stal) and Tetranychus urticae (Koch) adults through topical application an leaf-dipping methods, respectively. The insecticidal and acaricidal activities were both plant parts and species dependent. The methanol extracts from whole plants of Casia occidental is and Cassia tora (Caesalpinaceae), an stem of Prosopis chinensis (Mimosaceae) revealed potent insecticidal activity against N. lugens. Potnet acaricidal activity against T. urticae was obtained from the methanol extracts from whole plants of Celosia trigyna (Amaranthaceae) and Combretum micronthum (Combretaceeae), leaves of Combretm glutinotum, and leaves and fruits of prosopis chinensis.

아프리카 나이제르산 13관 21종 식물체의 부위별로 채집된 31 시료 메탄올 추출물의 벼멸구에 대한 살충활성 및 점박이이응애에 대한 살비활성을를 가각 미량국소처리법과 잎침지법으로 조사한 결고, 시료의 부위 및 종에 따라 살충 및 살비활성에 커다란 차이를 보였다. Caesalpinacras과의 Cassia occidentalis와 Cassia tora 전부위 및 Mimosaceas 과의 Prosopis chinensts줄기의 메탄올 추출물은 벼멸구에 대해서 강한 살충활성을 보인 반면, 비름과의 Celosia trigyna 전부위, Combretaceae과의 Combretum glutinotum 잎과 Combretum micronthum 전부위 및 Prosopis chinensis 잎과 열매의 메탄올 추출물은 점박이응애에 대해 강한 살비활성을 나타내었다.
