The present invention relates to an insect trapping device comprising a first body, a peripheral portion is provided with a first joint portion, and the first body is internally provided with a receiving groove, wherein the receiving groove is provided with a convex portion; a second body Removably fixed to the first body, the peripheral ring of the second body is provided with a second joint portion corresponding to the first joint portion for engaging and fixing with the first joint portion; A shielding member is coupled to the convex portion, and the shielding member is provided with at least one through hole for communicating with the outside. Since the apertures of the through holes are slightly larger than the size of the insects, the insects can no longer fly back out of the first body and the second body from the through holes, and the effect of capturing insects can be surely achieved.本創作係關於一種昆蟲誘捕裝置,包含有一第一本體,周緣係設有一第一結合部,又該第一本體內部設有一容納槽,該容納槽內設有一凸起部;一第二本體,係與該第一本體可拆地固定,該第二本體之周緣係環設有與該第一結合部相對應之一第二結合部,以供與該第一結合部相互卡合固定;一遮蔽件,係結合於該凸起部,該遮蔽件設有至少一透孔,以供與外界相通。藉由該等透孔之孔徑比昆蟲的體型略大,因此昆蟲無法再由該等透孔反向飛出該第一本體及該第二本體外,而可確實達到捕捉昆蟲之功效。
