【摘要】 在1954年11月至1955年3月初步调查长沙市蚊虫越冬的基础上,又于1956年1月至3月作了第二次调查,其结果如下: 1.白纹伊蚊(Aedes(Stegomyia) albopictus)确系以卵越冬。此蚊在树洞、竹筒、小罐及瓦缸中发现了越冬卵。树、竹名为枫树Liquidambar formosana Hance,臭辣树Evodia glauca Miq,冬青树Ilex purpurea var.oldhami Loes,黄檀属Dalbergia sp.,山槐Albizzia kalkora Prain,樟树Cinnamomum camphora Nees ＆ Eberm及江南竹Phyllostachys mitis等。 2.白雪伊蚊(Aedes(Finlaya)niveus)亦以卵越冬,与初步调查结果相似。它的越冬卵在白栎Quercus fabrei Hance,青刚栎Quercus glauca Thunb.,栎树一种Quercussp.,冬青Ilex purpurca var.oldhami Loes,冬青一种Ilex sp.,枫树Liquidambar for-mosana Hance,吴朱萸Evodia officinalis Dode,臭辣树Evodia glauca Miq,酸枣Spon-dias axillaris Roxb.,樟树Cinnamomum camphora Nees ＆ Eberm,山槐Albizziakalkora Prain,枳椇Hovenia dulcis Thunb,黄檀属Dalbergia sp.,朴树Celtis sinensisPers.,瑯瑜Ulmus parvifolia Jacq.等15种树的树洞内发现。 3.拟按蚊直脚蚊(Orthopodomyia anopheloides)的幼虫是这次发现的。它孳生在枫 树Liquidambar formosana Hance及黄檀?更多还原

【Abstract】 1. On the basis of the preliminary studies from November, 1954 to March, 1955,further studies on the hibernation of mosquitoes were carried out in Changshafrom January to March, 1956. During this period tree holes, bamboo stumps, jars. earthern pots, fertilizer pits containing feces, basements, green-houses and mountaincaves were targets for the collection of hibernating mosquitoes each week. As aresult of this collection three species of mosquitoes hibernating during the winterwere newly discovered. Including the original four known species, Aedes albopictus,Aedes niveus, Culex fatigans, and Anopheles hyrcanus var. sinensis, which were foundin the preliminary study, there are seven in total representing five genera. 2. Aedes albopictus was confirmed to bibernate in the egg stage. Eggs werefound in earthern pots, jars, bamboo stumps of Phyllostachys mitis, tree holes ofLiquidambar formosana Hance, Evodic glauca Miq., Ilex purpurea var. oldhami Loes,Dalbergia sp., Albizzia kalkora Prain, Cinnamomum camphora Nees and Eberm. 3. Aedes niveus was again found to hibernate in the egg stage in the treeholes of Quercus sp., Quercus fabrei Hance, Quercus glauca Thunb, Ilex sp., Ilex pur-purea var. oldhami Loes, Liquidambar formosana Hance, Evodia officinalis Dode,Evodia glauca Miq., Spondias axillaris Roxb., Cinnamomum camphora Nees andEberm, Albizzia kalkora Prain, Hovenia dulcis Thunb, Dalbergia sp., Celtis sinensisPers, Ulmus parvifolia Jacq. 4. The larvae of second, third and fourth instars of Orthopodomyia anopheloideswere found in the tree holes of Liquidambar formosana Hance and Dalbergia sp.Whether Orthopodomyia anopheloides will actually hibernate in the larval stageneeds further observation for confirmation. 5. Armigeres obturbans was found to hibernate in the larval stage under thecover of grasses, leaves, twigs and so forth on the surface of water in fecal pits. 6. Culex hayashii was found to hibernate in the adult stage. Both male andfemale adults were caught in the mountain caves. The quantity of fat bodieswithin the female was noted and analysed. 7. Culex fatigans was again found to hibernate in the adult stage. Both maleand female adults were caught in tbe basements, greenhouses and mountain caves.But its chief shelter for hibernation was in mountain caves where the majority ofthis species was caught. Dissections showed that the quantity of fat bodies washigh for those adults which were caught in January and February while thosecaught in March showed a lower fat body content. After hibernation was over thefirst adults engorged with blood was caught on March 22nd. 8. The hibernation of Anopheles kyrcanus var. sinensis in adult stage was veri-fied. Female adults were caught chiefly in mountain caves. The condition of thewings, the development of ovaries as well as the quantity of fat bodies were notedand analyzed. After hibernation the first two females engorged with blood werecollected on March first. 9. The influence of temperature, humidity and light in the shelters where theadults of Culex hayashii, Culex fatigans and Ahopheles hyrcanus var. sinensis passedthe winter has been discussed.更多还原
