Bemisia tabaci is also called “little white mothâ€. Although its body length is less than 1 mm, it has high feeding habits, rapid reproduction, large amount of eggs laid, and large amount of occurrence. In addition, the insect has strong migratory ability, long-term harm, and resistance. The characteristics of strong medicinal properties make it difficult to prevent and control work. In this regard, the author specifically prepared the following, for the reader's reference. First, control methods: The use of highly toxic pesticides should not be used in the prevention and treatment to protect the natural enemies such as citrifolia, beetle hornets, bees, ladybugs, grasshoppers, and flower buds that have a good inhibitory effect on whiteflies. Yellow plates can be trapped to kill adults in the greenhouse or in the field. It is recommended to use the following agents to prevent and treat 5% acetamiprid 800 times. The drug is currently the preferred pesticide for killing sucking pests. The control of Bemisia tabaci is cheap, effective, and cost-effective, and the insecticidal activity is higher than imidacloprid under cool autumn weather conditions. It is recommended that pesticides be mixed with other ingredients to reduce costs and improve efficacy. 25% buprofezin (buprofezin) 1000 to 1500 times. There is no direct killing effect on adult worms. Generally, they are effective 3 to 7 days after treatment, but they have a longer effective period. Need special attention is that the drug on cabbage, radish is easy to produce brown spots and green leaves and other phytotoxicity. 25% Aktai (Thiamethoxam) 2500 to 5000 times. The rate of insecticide is slow, and the peak of dead insects is generally 2 to 3 days after application. "Lanke 140" 3000 times liquid + "Nongxi 1" 1000 times liquid. According to the test of cotton farmers in Guangping County, Shandong Province, the effect of removing Bemisia tabaci can reach 90%, and it can simultaneously treat aphids, red spiders, beet armyworm, cotton bollworm, cabbage caterpillar and so on. The effective period is 10 to 15 days. The Bayer company's "Muwangte" 4000 to 5000 times liquid. The composition of the drug is spirotetramat, which is a new type of pesticide with two-way systemic absorption and transmission properties. It mainly causes the death of larvae by interfering with the fat biosynthesis of insects. According to trials in Qingzhou and Liaocheng in Shandong Province, one spray can be effective for 15 to 20 days. Second, special reminder: 1. "Large governance and early treatment" is the key to obtaining the best control effect. In the case of a low population density and a small worm age, prevention and control can have a multiplier effect. 2. It is important to master medications in the evening for the weaknesses of their ability to fall in the evening. And we must pay attention to even spray, improve control and reduce the spread of debris. 3. Due to the high density of the whitefly locusts and overlapping generations, spraying should be repeated 3 to 5 days after application. And pay attention to alternate medication and rational compounding to avoid drug resistance. 4. The whitefly on the body and wings of Bemisia tabaci may be added with a small amount of neutral detergent (with a concentration of no more than 0.05%) in the prepared liquid to increase the insecticidal effect. 5. Pay attention to the reasonable application of phosphorus and potassium fertilizers, which can not only promote the high yield and quality of crops, but also reduce the damage of whitefly.
