蛋白质和氨基酸对2种蚊虫产卵选择的影响

目的评价不同蛋白质和氨基酸对我国2种重要媒介蚊虫淡色库蚊和白纹伊蚊雌蚊产卵选择的影响,为新型蚊虫诱卵器的研制提供理论支持。方法在室内测定淡色库蚊和白纹伊蚊对不同种类蛋白质和氨基酸溶液的产卵趋性。结果淡色库蚊怀卵雌蚊偏好在较高浓度的鱼蛋白胨溶液(1000和100mg/L)和酵母浸膏溶液(1000mg/L)中产卵,而10mg/L浓度的鱼蛋白胨溶液能显著引诱白纹伊蚊产卵;苯丙氨酸溶液在1000、100和10mg/L3个实验浓度下均能显著引诱淡色库蚊和白纹伊蚊产卵。结论鱼蛋白胨和苯丙氨酸对淡色库蚊和白纹伊蚊在室内有较好的产卵引诱效果。

The oviposition responses of gravid Culex pipiens pallens and Aedes albopictus females to waters with protein or amino acid

Objective To evaluate the influence of different proteins and amino acids on the oviposition behavior of gravid female Culex pipiens pallens and Aedes albopictus under laboratory conditions,providing theoretical basis for the development of a highly effective ovitrap.Methods The oviposition preference of gravid female Cx.pipiens pallens and Ae.albopictus to different concentrations of protein and amino acid solutions was determined under laboratory settings.Results The gravid female Cx.pipiens pallens preferred to lay eggs in fish peptone solutions of 1000 mg/L and 100 mg/L and in yeast extraction solution of 1000 mg/L;the gravid female Ae.albopictus only preferred to lay eggs in fish peptone solution of 10 mg/L.Phenylalanine solutions of 1000,100 and 10 mg/L could produce a significant oviposition preference for both Cx.pipiens pallens and Ae.albopictus.Conclusion Gravid Cx.pipiens pallens and Ae.albopictus have a high oviposition preference to fish peptone and phenylalanine.
