Female Fruit Fly Trap with Female Pheromone = Field-effective packaging lasts 90 days. = Slow release. = Semi-liquid formulation. = Dripping technology. It is installed on the female fruit fly trap = Pheromone bait (patented semi-liquid formulation) 65 ml per package (cartridge). = This quantity is sufficient to cover an area of one to one and a half acres for the experiment (acre = 4000 square meters). = When installed on the designed (patented) trap, 4 to 6 drops fall daily. = The refreshing scent of the bait attracts all three stages of the female fruit fly (larva, adult, and carrier). = Dripping lasts for 90 days (one agricultural cycle). = Next time, the customer should buy only the cartridge and install it on the trap. = Suitable for all types of fruits (peaches, guavas, lychees, mangoes, pumpkins) and other types of fruits. = The bait mimics food to attract the fly at all its growth stages. = The pregnant female thinks it is a fruit, so she is attracted to it (thinking she will pierce it and lay her eggs). I assure you that it is much more effective than the method of trapping only males, and both are complementary to each other, so both types of traps should be used.
