Rice white backed planthopper
The scientific name *Sogatella furcifera* (Horváth) belongs to the order Hemiptera, specifically the family Delphacidae. This pest is commonly found in rice-growing regions across China, particularly in areas like Yunnan and other parts where rice is extensively cultivated. The primary host plants include rice, wheat, corn, barley, sugarcane, sorghum, grasses, and bluegrass. It is a significant agricultural pest due to its feeding habits and ability to transmit plant viruses. The damage caused by this planthopper is similar to that of the brown planthopper, often leading to yellowing, stunting, and even death of rice plants. **Morphological Characteristics**: Male adults with long wings have a body length of 3.2–3.8 mm, typically light yellow with dark brown spots. They feature a protruding head, dark brown crescent-shaped spots on the sides of the compound eyes, and a dark brown area on the middle of the thorax. Their forewings are translucent with a brown halo at the tip. Female adults are slightly larger, measuring 4–4.5 mm, with a yellowish-white color and light brown markings. Eggs are crescent-shaped, about 0.7–0.8 mm in length. There are five nymphal instars, with the final stage being gray and approximately 2.9 mm in size. **Life Habits**: In Xinjiang and Ningxia, it completes 1–2 generations per year, while in the northeast, it has 2–3 generations. South of the Huai River, there are 3–4 generations, and in the Yangtze River Valley, up to 4–7. In southern Hainan, it can have as many as 11 generations annually. This species is migratory, with the original population originating from the south. Migration patterns shift northward over time, and multiple generations often overlap. Adult long-winged individuals have strong flight capabilities, with each female laying around 85 eggs. When the population grows rapidly—typically 2–4 times during a generation—the density increases significantly before migration occurs. **Prevention Methods**: (1) Planting resistant rice varieties such as 'Early Glaze No. 42' can help reduce infestations. (2) Follow standard control measures used for brown planthoppers, including cultural practices, biological control, and chemical pesticides when necessary. Monitoring populations regularly and taking timely action can prevent severe damage. Integrated pest management strategies are recommended for effective long-term control.
