1. Cotton bollworm. It is predicted that three generations of cotton bollworm will occur in Level 3 areas, while most of the fourth generation will be found in Level 3 and some parts of Level 4 will also be affected. The main reasons include: (1) Imbalance in the second generation of field populations. As of June 16th, the average number of eggs collected in the fields was monitored systematically, ranging from 6.2 to 113.5 per hundred plants, with a weighted average of 20.88, which is similar to previous years. The average cumulative insect count was 0–10 per hundred plants, with a weighted average of 1.71. (2) Climate conditions are not favorable for the second and third generations but beneficial for the fourth. According to weather forecasts, rainfall during the Meiyu period in northwest Hubei will be near normal, while other regions will see 1–2% less. In early May, there was a brief rainy period, and summer rainfall in northeastern and southeastern Hubei will be close to normal, while other areas will have slightly less. (3) The growth of cotton, especially in July when it enters the flowering and boll stage, provides good nutritional conditions. After the harvest of vegetable hosts, cotton bollworms shift their focus to cotton fields. (4) The spread of Bemisia tabaci has increased, and its control helps reduce the population of Helicoverpa armigera. 2. Cotton whitefly. It is expected that the occurrence of Bemisia tabaci in Edong and the Jianghan Plain will reach Grade 4, while mixed vegetable and cotton planting areas will be at Grade 5, and the entire province will be at Grade 3. The peak damage is expected to begin in late July. Main reasons: (1) Bemisia tabaci has recently entered cotton fields, and current numbers are low. On June 3, Hanchuan station reported 1–3 adult whiteflies per 100 cotton plants. In early June, some cotton fields in Xiantao, Xishui, and Tuanfeng showed signs of infestation. (2) Spring and summer vegetables had significantly fewer whiteflies compared to last year, with reduced pesticide use by farmers, which supports whitefly breeding. When vegetables are harvested, whiteflies move to cotton fields. (3) Weather forecasts indicate that the plum season will start in early July, and summer rainfall in major cotton areas will be lower than usual, which is favorable for whitefly development. 3. Cotton spider mites. Most of the province’s cotton areas are expected to experience Grade 4 infestations, with some local areas reaching Grade 5. The peak period is expected between late July and late August. Main reasons: (1) Field populations are currently widespread, with high base levels. In mid-to-late June, the number of mites per 100 plants ranged from 56 to 786.67, averaging 400.32. (2) Weather conditions are favorable. During the Meiyu period, rainfall was less, and the dry conditions continue into summer, which benefits spider mite development. 4. Aphids. Aphid occurrence is expected to be at Grade 3 across the province, with some local areas reaching Grade 4. The main reason is: (1) High field populations were observed in mid-to-late June, with counts ranging from 99.2 to 567 heads per 100 plants, averaging 328.9. (2) High temperatures and limited rain after the Meiyu season have somewhat suppressed aphid activity. 5. Red cotton bug. It is expected that the third and fourth generations of red cotton bugs will reach Grade 4 in most cotton-growing areas of the province. Main reasons: (1) Field base levels are high. Seedling stage counts ranged from 2.23 to 26.7 heads per 100 plants, averaging 12.11, which is higher than the same period last year. (2) Large intercropped cotton areas favor their occurrence. 6. Pink bollworm. The second and third generations of pink bollworms are expected to be at Grades 2 and 3, respectively. Main reasons: (1) The population is light, with a low base. (2) Insect-resistant cotton varieties have a strong inhibitory effect on pink bollworms. 7. Cutworm (Spodoptera litura). It is expected that the province will experience a Grade 4 infestation, with some local areas reaching Grade 5. There is a risk of outbreaks in vegetable and cotton intercropping areas. Main reasons: (1) Heavy infestations occurred last year, leading to a high base. (2) Multiple crop interplanting patterns favor its occurrence, especially in cotton fields interplanted with soybeans, vegetables, and melons. 8. Wilt and Verticillium wilt. It is expected that the disease will occur at Grade 4 in the old cotton areas, with some local areas reaching Grade 5. Main reasons: (1) Disease sources are widespread, with sufficient bacterial presence. Surveys in mid-to-early June showed an average diseased rate of 3.2–12.5%, lighter than the same period last year but heavier than in previous years. (2) Concentrated rainfall during the Meiyu period favors the development of wilt diseases. (3) Main cotton cultivars have poor resistance, making them more susceptible to infection.
