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://odonatas.myspecies.info/node/7202053nas a2200169   4500008004100000245016800041210006900209260000800278300001100286490000700297520145900304100002201763700001601785700001901801700001901820856004401839       1999                        eng d00aPhylogenetic relationships of North American damselflies of the genus Ischnura (Odonata: Zygoptera: Coenagrionidae) based on sequences of three mitochondrial genes0 aPhylogenetic relationships of North American damselflies of the   cFeb  a110-210 v113 aRelationships of North American damselflies of the genus Ischnura (Odonata: Zygoptera: Coenagrionidae) were investigated using a total of 1205 bp from portions of three mitochondrial genes: cytochrome b, cytochrome oxidase II, and 12S ribosomal DNA. Parsimony and neighbor joining analyses reveal a monophyletic group consisting of I. damula, I. demorsa, I. perparva, I. posita posita, I. posita atezca, I. verticalis, and probably I. denticollis, likely reflecting a recent radiation in North America. Ischnura kellicotti, I. barberi, I. prognata, I. hastata, I. ramburii, and I. capreola appear to represent much earlier divergences in the group. Many previous hypotheses of relationships among North American species of Ischnura are not supported by the molecular-based analyses. However, there is agreement in many respects between the results of the molecular phylogenetic analyses and the morphologically based conclusions of Kennedy (1919, "The Phylogeny of the Zygoptera," Ph.D. Dissertation, Cornell University, Ithaca). Although results of single-gene phylogenetic analyses often differ, there are very few cases in which there is strong support for conflicting relationships using different partitions of the data. Combined analysis of all three genes yields trees with stronger support overall than the single-gene analyses, and the combined data trees that result from diverse data treatments are congruent with one another in most respects.1 aChippindale, P, T1 aDavé, V, K1 aWhitmore, D, H1 aRobinson, J, V  uhttps://odonatas.myspecies.info/node/7301717nas a2200133   4500008004100000245013600041210006900177300001000246490000700256520124500263100001701508700001401525856004401539       1999                        eng d00aPopulation dynamics of mosquito immatures and the succession in abundance of aquatic insects in rice fields in Madurai, South India0 aPopulation dynamics of mosquito immatures and the succession in   a19-320 v363 aStudies on the breeding pattern of mosquito immatures and the successional changes in the abundance of aquatic insects were conducted in rice fields near Madurai, south India. The population of late (III/IV) larval instars of culicines peaked on Day 28 and pupae (Culex tritaeniorhynchus, Cx. pseudovishnui and Cx. vishnui) peaked on Day 9 after transplantation, whereas the population of late (III/IV) larval instars of anophelines peaked on Day 19 and pupae of Anopheles subpictus and An. vagus on Days 7 and 9 respectively, after transplantation of paddy. A total of 14 families (consisting of 17 subfamilies) of aquatic insects belonging to six different orders, Coleoptera, Diptera, Ephemeroptera, Hemiptera, Anisoptera and Zygoptera were collected during the study period and the abundance of each group of insects is discussed in detail. The Shannon-Weaver Diversity Index, applied to study the diversity of different groups of aquatic insects, showed a clear pattern in diversity of surface predators, bottom predators and non-predators of mosquito immatures. The multiple linear regression model reveals that notonectid adults, coenagrionids, libellulids and veliids act as important predators of mosquito immatures in rice fields.1 aVictor, T, J1 aReuben, R  uhttps://odonatas.myspecies.info/node/74
