Studies on the population estimation for insects of medical importance. IV. A method for the estimation of the relative density of Culex tritaeniorhynchus summorosus larvae in the whole paddy-fields of an area

, : Studies on the population estimation for insects of medical importance. IV. A method for the estimation of the relative density of Culex tritaeniorhynchus summorosus larvae in the whole paddy-fields of an area. Tropical Medicine 13(2): 86-93

An account is given of continued studies in the Nagasaki area of Japan on the estimation of populations of larvae of Culex tritaeniorhynchus summorosus Dyar by sequential sampling. The technique for estimating the relative density of larvae in the rice-fields of an area based on the variation in the numbers between rice-fields was examined and is discussed.
