The invention discloses a sex
trapping cage with
virus and a method for controlling lepidopteran pests with the same. The
trapping cage comprises a sunscreen film cover, a hook, a
metal ring buckle, a conical net and a poison-carrying basin; the hook is connected to an upper cover frame; a
metal ring buckle is hung at the bottom of the upper cover frame; two ends of the conical net are respectively fixed to the
metal ring buckle and the lower cover frame; the poison-carrying basin is hung at the bottom of the lower cover frame, and a
sponge block placed in the poison-carrying basin is soaked with
virus liquid; and a lure core is hung at the bottom of the metal ring buckle. During the
crop growth period, more than two poison-carrying
trapping cages are placed in each mu of field, which can effectively control the harm of lepidopteran pests, reduce the amount of chemical pesticides applied, and significantly reduce the cost of
pest control. The organic combination of sex
pheromone trapping and
virus infection, two
pest control measures, is achieved, the
mating probability of male and female insects is reduced, and the male
insect can take the virus liquid into the body, so that the infected male
insect mates with the female
insect, and the virus is vertically transmitted in the
population, thereby achieving precise control of physical and biological control.
