Open ground pools, mainly in depressions made by the treads of bulldozers and other heavy equipment, were numerous but because of their small size, comprised ca. 1% or less of the total area of the deforested lands studied. The dominant mosquitoes in these pools were Anopheles vagus, Culex vishnui, Culex tritaeniorhynchus, and Culex gelidus. The 1st 2 species were dominant in clear pools, whereas the latter 2 species were dominant in turbid pools. The dominant metazoans other than mosquitoes were Crustacea, Ephemeroptera, and Chironomidae. Both aquatic and surface predators were abundant. Dominant among aquatic predators were Anisoptera and Zygoptera nymphs, Dytiscidae, and Notonectidae. These results are discussed in relation to mosquito control on deforested lands that transitionally but inevitably appear during the course of rice field development projects in Indonesia.1 aMogi, M1 aSunahara, T1 aSelomo, M  uhttps://worldodonata.myspecies.info/node/27201718nas a2200145   4500008004100000245015100041210006900192260000800261300001000269490000700279520121100286100001201497700001401509856004901523       1990                        eng d00aColonization of rice fields by mosquitoes (Diptera: Culicidae) and larvivorous predators in asynchronous rice cultivation areas in the Philippines0 aColonization of rice fields by mosquitoes Diptera Culicidae and   cJul  a530-60 v273 aColonization of rice fields by mosquitoes and larvivorous predators was studied in asynchronous rice cultivation areas in the Philippines. Dipper samples were taken from rice fields at six phases of maturity (fallow, ploughed, nursery, newly transplanted, after tillering, mature). All phases were present concurrently at each of two study sites. Abundance levels of the vishnui subgroup of Culex and of the genus Anopheles were high in ploughed fields, nurseries, and newly transplanted fields; this was primarily because of the concentration of Culex vishnui. Theobald and Anopheles vagus Doenitz in those fields with short, sparse vegetation. Dytiscidae, Anisoptera, and Zygoptera were more abundant in fallow or mature fields. The abundance of aquatic predators decreased at the onset of ploughing and then recovered slowly as rice plants grew. The abundance of surface predators showed a similar pattern, but less conspicuously. The abundance of nonpredators (other than mosquitoes) was relatively stable with regard to rice field phases. Alleviation of mortality by predation was considered to be a secondary cause of increased mosquito abundance in the fields under early phases of rice cultivation.1 aMogi, M1 aMiyagi, I  uhttps://worldodonata.myspecies.info/node/278
