Rice planthoppers pose a serious threat to rice growth. The adults are tiny, only a few millimeters long, with colors similar to the paddy field environment. Their movements are covert, making them difficult to detect with the naked eye. They use piercing - sucking mouthparts to suck the sap of rice plants.
Rice planthoppers have extremely strong reproductive capabilities. A single female can lay hundreds of eggs, and the hatching rate is high. Under suitable conditions, a new generation can be reproduced in a few weeks, and the population size can increase exponentially in a short time.
Rice planthoppers cause harm to rice in multiple ways. In the initial stage, they cause chlorotic spots on the leaves. Subsequently, these spots expand, and the leaves turn yellow, wither, and curl, affecting photosynthesis. When a large number of them gather at the base of the stems, the stems are damaged, and the rice plants are prone to lodging. Some rice planthoppers also carry viruses, infecting the rice plants and seriously affecting the yield.
Due to their small size, rapid reproduction, and the difficulty in detecting their early - stage damage, and the fact that they mostly hide at the lower part of the plants, pest infestations are often severe by the time they are discovered.
Prevention and control measures require strengthening field inspections, using insect monitoring and forecasting instruments for monitoring, and comprehensively applying agricultural control methods such as reasonable close - planting, scientific fertilization, and proper drainage; selecting appropriate pesticides for chemical control; and using natural enemies for biological control. By using these multiple measures, we can ensure a good rice harvest.
The Rice planthopper monitor FT - SD1 is a powerful device for agricultural and forestry pest monitoring and prediction.
It has a high degree of automation, integrating optical, electrical, and numerical control technologies. It can automatically complete a series of operations such as far - infrared treatment of insect bodies, insect dispersal, photo - uploading, and insect cleaning. It can also perform system operations such as trapping and killing insects on its own without supervision.
It is convenient to operate and display. It is equipped with a 7 - inch color Chinese - language LCD capacitive touch screen, which is intelligently controlled based on the Android system. It allows for time - segmented settings, automatic or manual photo - taking, and real - time display of environmental temperature, humidity, and time.
It has diverse and accurate data collection capabilities. It is equipped with a 1200 - W - pixel image - collection device and a grating counting device, which are respectively used for real - time collection of insect body pictures and recording the number of insects, and then uploading the data to the platform. It can also add multiple sensor interfaces to study the relationship between the environment and pests and diseases.
Data transmission and management are convenient. It supports networking methods such as 4G, WiFi, and wired connections. Data and alarm parameters can be uploaded to a remote server and viewed through a PC, APP, or WeChat. It has functions such as traffic alarm, GPS, and Beidou positioning.
The insect body treatment is highly efficient. After the two - layer far - infrared treatment chamber works for 15 minutes, the temperature reaches 85±5℃, with a lethality rate of not less than 98% and an insect body integrity rate of not less than 95%. It is also possible to remotely control the switch of devices such as insect - trapping lamps through the platform.
It has rich control functions. It can set working periods according to the habits of pests, and has functions such as light control and rain control. A separate drainage system realizes the separation of rainwater and insects.
The solar panel has a power of 600W, the battery is 12V 200AH, the standby power consumption is ≤5W, the overall lamp power is ≤450W, the 20W black - light lamp tube has a main wavelength of 365nm. The impact screen is reasonably designed, the lamp tube starts up quickly, and the insulation resistance is high, ensuring the stable operation of the device.
