摘要
研究了在25℃条件下,西花蓟马分别以四季豆豆荚、四季豆叶片、大豆叶片、豇豆叶片为食料时,两性生殖和孤雌生殖方式下的繁殖力。结果表明,不同豆科蔬菜对西花蓟马繁殖力有很大的影响,不论是两性生殖还是孤雌生殖,均以取食四季豆豆荚时平均产卵量和日均产卵量最高,取食豇豆时日均产卵量最低。两性生殖的后代以雌虫为主,取食四季豆豆荚时雌雄比例最高,达2.85∶1,孤雌生殖的后代皆为雄虫。
The fecundity of bisexual reproduction and parthenogenesis of Frankliniella occidentalis was studied at 25 when pods of Phaseolus vulgarion leaves of Phaseolus vulgari, Glycine max and Vigna sinensis were used as feeds. The results showed that different leguminous vegetables had different influence on the fecundity of FranklinieUa occidentalis. The average eggs and mean daily eggs of Frankliniella occidentalis feeding on pods of Phaseolus vulgarion was the highest and mean daily eggs of Frankliniella occidentalis feeding on leaves of Vigna slnensis was the lowest in both bisexual reproduction and parthenogenesis. The females were dominant in the offspring produced from the bisexual reproduction. The highest ratio of female to male was up to 2.85：1 when pods of Phaseolus vulgarion was used as feed. The offspring of parthenogenesis was all males.
