摘要
测试广西12种野生楝科(M eliaceae)植物提取物对黄曲条跳甲成虫[P hy llotreta str iolata(F abricius)]的非选择性拒食作用和毒杀作用。结果表明,供试浓度为10g/L时,海木(H eynea tr ijug a)、山楝(Aphanam ir ispoly tachya)及海南坚木(D ysoxy lum ha inanense)提取物对黄曲条跳甲有较好的毒杀效果,24h校正死亡率分别为78.17%、60.51%和59.81%;米仔兰B(Ag la ia sp.)、灰毛浆果楝枝叶(C ip ad essa cinerascens)、地黄连(M eliasin ica D iels)、米仔兰(Ag la ia od orata Lour)、麻楝(Chud rasia tabu lar is)及山楝(Aphanam ir is poly tachya)拒食效果最好,24h拒食率分别为98.70%、97.49%、90.26%、90.16%、84.14%和84.07%。
Non choice Antifeeding and contact toxic effect of crude extracts of 12 species of wild Meliaceae from Guangxi were evaluated by the laboratory bioassay against the adult of Phyllotreta striolata （Fabricius）. The results showed that when the concentration of the extracts reached 10g/ L, the extract from branches and leaves of Heynea trijuga, Aphanamiris polytachya and Dysoxylum hainanense had marked significant contact toxic effect,corrected mortality in 24h reached 78.17%、60. 51% and 59.81% respectively;the extracts from Aglaia sp. ,branches and leaves of Cipadessa cinerascens, Melia sinica Diels, Aglaia odorata Lour,Chudrasia tabularis, Aphanamiris pol ytach ya had the most antifeeding effect with antifeeding rates of 98.70%、 97. 49%、 90. 26%、 90. 16%、 84.14%、84.07% and 80. 72% in 24h respectively.
