2, diflubenzuron pharmaceutical suspensions for Lepidoptera larvae cypermethrin, its mode of action is a stomach poison. Prevention is the best time for young larvae (ie, before age 3). Because these agents are interfering Fluoride cypermethrin insect physiological functions of the endocrine glands, leading to loss of insect body's hormone balance and alter enzyme activity. Insect growth hormone levels are not exactly the same as the various stages of cypermethrin, the physiological state of the various cells and tissues which are different, so different developmental stages of insects have significant differences in the sensitivity of the drug, the more sensitive the lower age class of agents, markedly faster. Practice shows that 25% diflubenzuron on the 3rd 1500 times, most of the larvae of lepidopteran pests effects, its killing effect of peach borer eggs as much as 1605.
