 note = {The distributions of the numbers of Culex tritaeniorhynchus summorosus larvae per dip in respective paddy-fields were proved to be of an aggregated type and to be fitted well to the negative binomial distributions with a common k. It was also proved that the sequential sampling method based on this distribution pattern can properly be used to classify the larval density of each of paddy-fields examined, into one of the three density levels, low, moderate, and high, at a given statistical reliability by a relatively small number of dips, and in turn to compare the breeding situation of the paddy-fields in question., 個々の水田におけるコガタアカイエカ幼虫の柄杓当りの個体数は集中分布を示し,共通のkを持つ負の2項分布に適合することを証明した.この分布型を基礎とした逐次抽出法は,個々の水田の幼虫密度を,ある一定の統計的確かさからしで,しかも比較的少ない掬いとり回数で,低,中,高の何れかに分類することができ,ひいては,個々の水田の幼虫の発生量を比較するのに役立つ., 熱帯医学 Tropical medicine 13(1). p16-25, 1971},
