Within the entomological monitoring program of the German federal ministry of food, agriculture, and user protection (BMELV), at 12 cattle farms in Rhineland-Palatinate and two in Saarland, ultraviolet lamp traps were used to monitor the distribution and seasonal appearance of potential vectors of the bluetongue virus, with special consideration of species of Culicoides. Using the traps during the first seven nights of each month from April 2007 to May 2008, 5,000-120,000 ceratopogonids were caught at different locations, in total about 500,000 and mainly females. Ninety-four percent belonged to the genus Culicoides, and of these, 90% were Culicoides obsoletus s.l., 6% were Culicoides pulicaris s.l., and 4% were other species of this genus. In all traps, the first ceratopogonids were caught in April 2007, the total number peaking in August 2007. After a reduction in September, a lower peak occurred in October. During the whole winter, some ceratopogonids were active. At nearly all locations, the total numbers of C. obsoletus s.l., C. pulicaris s.l., and of other ceratopogonids were significantly correlated with the temperatures, and higher population densities of C. obsoletus s.l. seemed to occur at altitudes of about 300 m above sea level.
在德国联邦食品、农业和消费者保护部（BMELV）的昆虫学监测项目中，在莱茵兰 - 普法尔茨州的12个养牛场和萨尔兰州的2个养牛场，使用紫外线诱捕灯监测蓝舌病病毒潜在传播媒介的分布和季节性出现情况，特别关注库蠓属物种。在2007年4月至2008年5月期间，每月的前七个晚上使用诱捕器，在不同地点捕获了5000 - 120000只蠓科昆虫，总共约500000只，且主要为雌性。94%属于库蠓属，其中90%是奥氏库蠓复合种（Culicoides obsoletus s.l.），6%是刺螫库蠓复合种（Culicoides pulicaris s.l.），4%是该属的其他物种。在所有诱捕器中，第一批蠓科昆虫于2007年4月捕获，总数在2007年8月达到峰值。9月数量减少后，10月出现了一个较低的峰值。整个冬季，仍有一些蠓科昆虫活动。几乎在所有地点，奥氏库蠓复合种、刺螫库蠓复合种和其他蠓科昆虫的总数与温度显著相关，奥氏库蠓复合种似乎在海拔约300米处有较高的种群密度。
