Some limnic copepod species are predators of mosquito larvae. Seven species belonging to the order Cyclopoida, family Cyclopidae, were collected in the field in Germany and tested for the first time in laboratory bioassays for their potential to serve as biological control agents of the invasive Asian bush mosquito Aedes japonicus (Theobald), a vector of various pathogens causing disease. Females of Diacyclops bicuspidatus (Claus) did not attack 1 instar larvae of Ae. japonicus, but Macrocyclops distinctus (Richard), Cyclops divergens Lindberg, and C. heberti Einsle predated a mean of 14, 18, or 19 1 instar larvae, respectively. Acanthocyclops einslei Mirabdullayev and Defaye killed 30 larvae, and high predation rates with a mean of 39 or 46 larvae, respectively, were obtained by Megacyclops viridis (Jurine) and M. gigas (Claus). In regression analyses, predation rates by M. viridis correlated with body size, with specimens of 1.8 mm length being more effective than smaller or bigger ones. Based on the presented data, the two Megacyclops species seem to be promising candidates for use in field studies on the biological control of Ae. japonicus.
一些淡水桡足类物种是蚊子幼虫的捕食者。在德国野外采集了属于剑水蚤目、剑水蚤科的7个物种，并首次在实验室生物测定中测试了它们作为入侵性亚洲丛林蚊子日本伊蚊（Theobald）生物防治剂的潜力，日本伊蚊是多种致病病原体的传播媒介。双齿大剑水蚤（Claus）的雌虫不攻击日本伊蚊的1龄幼虫，但奇异大剑水蚤（Richard）、分歧剑水蚤Lindberg和赫氏剑水蚤Einsle分别平均捕食14、18或19只1龄幼虫。艾氏棘剑水蚤Mirabdullayev和Defaye杀死了30只幼虫，绿色大剑水蚤（Jurine）和巨型大剑水蚤（Claus）分别获得了平均39或46只幼虫的高捕食率。在回归分析中，绿色大剑水蚤的捕食率与体型相关，体长1.8毫米的标本比更小或更大的标本更有效。根据所提供的数据，这两种大剑水蚤似乎是用于日本伊蚊生物防治田间研究的有前途的候选物种。
