The bean borer, also known as candied bean, is one of the main pests that harms beans.
The adults of P. tigrinae disperse and hide, flying spawning range is large, and the amount of spawning is large. It is not easy to cull or seduce, adults lay eggs on the young leaves of plants, and the incubation period is 5-7 days. More than 3 instar larvae burrow into the cockroach to feed, and it is difficult to kill them by spraying the medicine. Therefore, prevention and treatment of this insect should be strengthened with fertilizer and water management, so that the emergence of beans consistent, growing neat, relatively concentrated flowering and scarring, in order to focus on eradicating the pest.
Spraying drugs should adhere to the principle of governing buds and spraying larvae in flower buds during flowering. The spraying time is best when the flower buds are open at 8-10 o'clock on sunny days. After the cultivar has spent more than 10 centimeters on a long-time spraying, the young larvae that kill the newly hatched larvae and lick into the larvae can be killed.
