Abstract

Dengue Hemorrhagic Fever (DHF) is increasing every day so it is necessary to control efforts, namely by killing larvae using bay leaf plants (Syzygium polyanthum). The purpose of this study was to determine the effectiveness of the larvicidal solution of bay leaf in controlling larvae of Aedes sp. This research uses the true experiment method with Post Test Only Group Design. The concentration variations used were 0%, 15%, 20%, 25%, 30% and 35% in 100 mL of water with 4 repetitions. The population and samples used were Aedes aegypti and Aedes albopictus instar III larvae, each containing 600 larvae containing 25 larvae in each container. The results showed that the LC50 of bay leaf solution within 24 hours had the largest number of Aedes aegypti and Aedes albopictus larvae mortality at a concentration of 35% with 100% mortality. The results of the Anova Two Way test obtained a sig value. 0.000 < ɑ (0.05), meaning that there is an influence on the yield of dead larvae based on variations in concentration. It was concluded that each concentration of bay leaf solution could kill a different percentage of larvae. Suggestions for further researchers to determine the concentration variation of bay leaf larvicide solution which is more effective in killing Aedes sp.

登革出血热(DHF)每天都在增加，因此有必要采取控制措施，即使用月桂叶植物(Syzygium polyanthum)杀死其幼虫。本研究的目的是确定月桂叶灭幼虫液对伊蚊幼虫的控制效果。本研究采用纯试验后组设计的真实验方法。使用的浓度变化分别为0%、15%、20%、25%、30%和35%，在100 mL水中重复4次。使用的种群和样本为埃及伊蚊和白纹伊蚊幼虫，每只幼虫600只，每个容器25只。结果表明，月桂叶溶液24 h内LC50浓度为35%时，埃及伊蚊和白纹伊蚊幼虫死亡率最高，死亡率为100%;方差分析双向检验的结果得到一个sig值。0.000 < j(0.05)，说明在浓度变化的基础上对死亡幼虫的产量有影响。结果表明，不同浓度月桂叶溶液对幼虫的杀伤率不同。对进一步确定杀伊蚊效果更好的月桂叶杀幼虫液浓度变化的建议。
