Flies 2004 Weifang Port Baseline Survey
, Rotten fruit, tofu for the bait. To capture the spirit of live flies with the terminator killing, according to fly search table, sort out all the dead flies, classification, counting. Calculated density = 2.4 flies only a few flies / cage; a fly species in a certain month's ratio = number of months to capture a fly species / total number of the month to capture a variety of flies. 3.1 Population Category 3 findings of this survey flies were captured in 3793, identified by the classification into 5 families, 12 genera and 24 species, the list is as follows: Muscidae Muscidae Fannia white in the toilet is a toilet fly fly Fannial_ ~ ucostictaMeigen, 1826 Silver eyebrow black fly black fly is Ophym Ophyml_ ~ ucostomaWiedemann, 1817 black fly spot plantar OphymchalcogasterWiedemann, 1824 House fly Musca domestica is an AtherigonaRondani Muscadomesticavicina Mount Double Mao Mountain Fly Fly A, bisetakarl Calliphoridae Calliphoridae Lucilia sericata is a brilliant green flies LuciliaillustrisMeigen , 1826 Lucilia sericata LuciliasericataMeigen, 1826 P. fly I ~ ciliacuprinaWiedemann,[link widoczny dla zalogowanych], 1830 gold is Chrysomya flies Frontier Health and Quarantine of China on July 2OO5 Volume 28 Supplement Chin ~ FrontierHealthOuarantineJu1.2005,[link widoczny dla zalogowanych], Vol28, Sulr ~, lernent · 39 · megacephala ChrysomyamegacephalaFabricius, 1784 Sarcophagidae Sarcophagidea black Sarcophagidae are Helicophagella black-tailed black Sarcophagidae Helicophagellame | anui'aMeigen, 1826 fecal Sarcophagidae are Bercaea red tail fecal Sarcophagidae BercaeacruentataMeigen, 1826 flax flies are Parasarcophaga bald linen fly infringe uIxa Kawasaki call-l ~ igen, 1826 Send a fly Send knee Mountain Division Tachinidea Gonia flies are moth flies GoniachinensisWiedemann double knee Mount Send knee Mountain spotted missing mail be sent fly fly GoniabimculataWiedemann Cuphocem armyworm is required to send flies Cuphoceravariafabricius lack of substantial Send Dexia stupid flies are great to send flies Dexiavacuafallen Syrphidae Syrphidae 3.2 Syrphus eight kinds of species composition were collected in this survey 3793 adult flies, including Musca domestica 1208, accounting for 31.8% of the total catch flies, followed by Lucilia sericata 1083, accounting for 28.5% ( Table 1). 3.3 The density of flies in Weifang Port 6 October as the peak density of flies, fly to the highest density in August,[link widoczny dla zalogowanych], to 98.3 / cage,[link widoczny dla zalogowanych], the annual average density of 67.7 flies / cage (Figure 1). Table 1 Common Fly Weifang Port population composition Wuyi Zhen YU (months) Figure 1, density of flies in seasonal fluctuation of Weifang Port main fly species Figure 3.4 Seasonal variation in the main fly species growth and decline in different months (Table 2) suggest that the dominant fly species did not appear the same as the peak time. Lucilia sericata, Aedes toilet flies in the summer peak of 7 August; Musca domestica, Chrysomya megacephala usual peak in summer and autumn, the highest in August (Table 2). Table 2 Main fly species Weifang Port 4 to discuss the seasonal fluctuation survey, different survey points, the average density of different flies. The average density was significantly higher than the port city, container station. This may be related to ports, container freight station built, small population, the environment cleaner related. The survey also found that the port district of Weifang average, 79 high density of flies,[link widoczny dla zalogowanych], which may be related to climate, more rain related. Fly species in different months is not the same composition and growth and decline. Tip in the future should be based on different locations, time to take appropriate measures to Fly. The survey made clear Weifang Port species composition of flies. Because time is short, relatively simple methods of investigation, there may be some fly species not collected, and will continue to do investigative work, and improve the region's fly background information on fly control measures for the development to provide a scientific basis. The survey results are basically the same local information. [Received: 20o5-05 a l2] plus ∞ ∞ ∞ ∞ ∞ ∞ Canada
