Double-attraction deinsectization device used in agricultural greenhouse

The invention discloses a double-attraction deinsectization device used in an agricultural greenhouse. The device comprises a transparent box, an attraction lamp and a low-voltage power grid, both theattraction lamp and the low-voltage power grid are positioned in the transparent box which is a cuboid, and an escape-proof passage is formed in the side wall of the transparent box and comprises a lifting passage with height increasing from outside to inside and a sliding-down passage with height decreasing from outside to inside. When the device works for deinsectization, a driving motor is started to drive a fan to rotate, and upward airflow is generated in an ascending airflow cavity while descending airflow is generated in a descending airflow cavity by arranging a flow separating plate;when an insect is attracted to enter the transparent box through light of the attraction lamp, no resistance is received; when going out from the inside of the transparent box, the insect cannot normally enter the escape-proo
