Abstract: Objective To investigate the effective methods for improving hatching rates of Anopheles anthropophagus' eggs.Methods CollectingAn.anthropophagus' eggs from colony oviposition and single tube oviposition,then putting two kinds of eggs into water for hatching in groups respectively.Observing the larval amount of each group every day and calculating the hatching rates.Results The hatching rates of colony oviposition in groups:the group in agitated water(74.5%)> the group in knocked bason(73.4%) > the group in spurting water(71.9%) > the group brushed(60.9%)> the control group(35.6%);The hatching rates of single tube oviposition in groups:the group in knocked bason(92.5%) > the group in agitated water(88.0%) > the group in spurting water(83.2%)> the group brushed(81.4%)> the control group(50.7%).Conclusion The hatching rate of An.anthropophagus' eggs can be improved by the methods of knocking bason,agitating,spurting and brushing water.The method of knocking bason is the best to improve hatching rate of the mosquito.
