In 2010, Hongta District planned to plant 50,000 mu of rice, and the current planting of rice has basically ended. According to the light and field monitoring at the Plant Protection Station of Hongta District, due to the arid climate conditions and the early relocation of rice planthoppers in the southern region, the migration period has also advanced in our district, and the fieldworm population is higher than the same period of the calendar year. specialty. According to statistics from the Provincial Plant Protection Station, by April 30th, 2-6 batches of rice planthoppers had moved in Pu'er, Honghe and Wenshan in the south of our province. The 11 southern monitoring sites and the city's Yuanjiang and Xinping start-up periods were earlier than last year. Some areas have already caused damage in early rice fields and middle rice fields, and the area of ​​rice planthoppers in the province has reached 254,100 mu.
From the dynamic analysis of pest monitoring in the province, the whole city, and Hongta District, the ecological situation of rice planthoppers this year is still severe. It is hoped that the township agricultural technology station will cooperate with the plant protection station to monitor the occurrence and development of field pests. Publicity training and preparation for prevention and control.
1 Current pest situation
1.1 Lampworms
The first insect peak began to migrate to our area on May 1. The number of insects on a single day was 1,544, and 1849 insects were trapped on days 1 to 9. It was 4 to 5 days earlier than in 2009, and the amount of insects was slightly lower than in 2009. . The number of insects accumulated from May 5 to May 6 was 1,490, and the total number of insects attracted 3016 from 1 to 9 days. No peaks migrated in the same period of the calendar year.
1.2 Field pest field investigations: In the first, mid and late quarters of April, the number of insects per square meter was 2.6 heads, 3.62 heads and 13.43 heads, respectively. The amount of insects per square meter in the same period in 2009 was 0.27 heads, 3.9 heads and 7.6 heads respectively.
Field survey: On May 5th, the number of 100 insects was 10.3, and May 10 was 9.5. In the same period of 2009, they were 5.0 heads and 38.6 heads respectively, which were 0.17 heads and 0.95 heads over the same period of the calendar year.
From the analysis of lamp and field monitoring results: Compared with previous years, in 2010, the migration of rice planthoppers in our area was 30 days earlier, and the density of insect populations was higher, posing a greater threat to safe rice production in the later period.
2 The next stage of prevention and control opinions This year due to the impact of a particularly severe autumn and winter spring drought once in a hundred years, the Xiaochun crops were seriously affected and the losses were huge. The pressure on the production of big springs was greater. In order to ensure the realization of the goal of “Large Spring Lossâ€, to ensure the safety of production of rice in the spring, and to reduce the damage caused by plant diseases and insect pests of rice planthoppers and other major crops, the agricultural technical departments of townships and townships should attach great importance to the timely arrangement of rice planthoppers. Dynamic monitoring work, accurate control of the situation in the township, timely guidance of farmers for scientific prevention. Anti-pharmaceutical agents: 15% gold good year cream 50ml/mu or 50-70% imidacloprid 3-5g/mu or 25% thiamethoxam water dispersible granules 4~8g/mu or 20% pymetrozine WP 20~30g/mu water 50kg spray.
