Biological studies on larval development, insemination and oviposi- tion of Anopheles minimus from Ishigaki Island, the Ryukyu Archipelago, were conducted under laboratory conditions. The larval developmental period was shortened and high pupation and emergence rates were obtained when larvae were reared under the conditions of the non-aeration method, standard food volume and 200-300 larvae per container. Insemination rate was increased with adult density per cage as well as cage size. The number of eggs per fed female was dependent on the method for oviposition. The study showed the following conditions to be suitable for rearing and obtaining a large number of An. minimus originated from Ishigaki Island, the Ryu- kyus: (1) the drip method for larval rearing should be used in the early generation to estimate suitable food volume and after that, by non-aeration; (2) 200-300 larvae per pan with food volume of 25 mg for the 1st, 50 mg for the 2nd, 100 mg for the 3rd and 150 mg for the 4th-instar larvae; (3) adult cage larger than at least the medium-sized cage; and (4) individual oviposition method in small vials.
