pieris rapae (linnaeus) Insecta Lepidoptera Pieridae belong, is a common butterfly in the world has distribution. Adult body length of 15-20 mm, head, chest, back, gray and black, white belly. Wingspan of 45-55 mm, white wings above, the following is a pale yellow, wing angle and wing base is gray and black, wing surface was being powdered. There are two spots on the forewings the females, the males have only one. First, the symptoms: There are 35 kinds of known host plants, but the main damage cruciferous vegetables. Such as cabbage, broccoli, and rape. Early instar caterpillar chewing on the dorsal mesophyll, residual skin, showed a small concave-shaped plaques, 3 years old after eating leaves into a hole or notch. Serious, only residual veins and petioles. Meanwhile emit large amounts of manure, contaminated lettuce and cabbage, so deterioration of the quality of vegetables and insect damage and rot provides a way for the invasion of bacteria, leading to the occurrence of soft rot vegetable plants, accelerate the death of the whole plant. Second, the control measures: ⑴ clean garden. The timely removal of leaves, stubble fields after harvest, concentrated fire to reduce population density. ⑵ manual capture. Larvae and pupae and adult capture is very easy to do, good adult available netting effect. ⑶ protection and use of natural enemies. This method is both pest and protect the environment, reduce pesticide pollution. ⑷ biological pesticides to control.
