The present invention relates to a retractor capable of improving insect trapping efficiency. The retractor injects the attractant of the attracting unit to the periphery of the suction pipe exposed from the inside of the casing, The attracting unit includes a attracting and discharging mechanism provided on the suction pipe for injecting a vapor-phase attracting agent and a liquid attracting agent to the outside, the attracting unit collecting the insect that has passed through the suction pipe by using a collecting net. A liquid attracting agent supply mechanism connected to the attracting and discharging mechanism through a discharge pipe to supply a vapor attracting agent and a liquid attracting agent drawn into the inside to the attracting agent dispensing mechanism； And a meteorological attracting agent supply mechanism connected to each other via the liquid supply agent supplying mechanism and a supply pipe to supply the meteorological attracting agent to the liquid attracting agent supplying apparatus； And a supply pipe connected to the liquid drawer supply mechanism and each end of the discharge pipe are spaced apart from each other so as not to come into contact with the liquid draw-in agent filled in the liquid supply drawer supply mechanism. According to the present embodiment, as a liquid inhaler (e.g., lactic acid, octenol, cyclohexanol, etc.) is sprayed together with a vapor attractant (e.g., carbon dioxide) It is possible to more effectively attract and collect pests (for example, mosquitoes) because the environment (environment) can be created, and there is an advantage that the collection efficiency can be maximized.본 발명은 해충포집효율을 향상시킬 수 있는 포충기에 관한 것으로서, 케이싱의 내부로부터 외부로 노출된 흡입관 주변으로 유인유닛의 유인제를 분사하여 이에 의해 몰려든 해충을 케이싱에 내설된 흡기팬을 매개로 강제흡입해 흡입관을 통과한 해충을 포집망을 이용해 포집하는 포충기에 있어서, 상기 유인유닛은, 상기 흡입관에 설치되어 기상유인제와 액상유인제를 외부로 분사하는 유인제 분사기구； 상기 유인제 분사기구와 배출관을 매개로 상호 연결되어 내부로 인입된 기상유인제와 액상유인제를 유인제 분사기구로 공급하는 액상유인제 공급기구와； 상기 액상유인제 공급기구와 공급관을 매개로 상호 연결되어 기상유인제를 액상유인제
