Blueberry drosophila attractant prepared from artemisia indica plant leaf extract

The invention discloses a blueberry fruit fly attractive toxicant prepared by utilizing an artemisia indica plant leaf extract, which is prepared by the following steps: A, wiping newly picked artemisia indica plant leaves with soft wet cloth, and cutting the leaves into small pieces with scissors; b, treating the cut leaf tissues by using an ozone disinfection machine; c, weighing 1-5 parts of disinfected folium artemisiae argyi leaves, putting the weighed folium artemisiae argyi leaves into a high-speed tissue stamping machine, and adding 10-30 parts of a 90% ethanol solution until leaf tissue liquid becomes homogenate; d, standing the leaf tissue fluid for 10-20 minutes, and filtering by using qualitative filter paper; e, evaporating the filtrate by using a low-temperature rotary evaporator to obtain an artemisia indica concentrated mother solution, and hermetically storing the mother solution in a refrigerator by using a shading bottle; and F, adding 10-20 parts of clear water into 1 part of the artemisia
