In the measurement and reporting of rice pests, the use of light trapping methods is very common and is the main basis for pest prediction and prediction. However, some lamps have a relatively slow death rate for insects, which can easily lead to insects escape or trapped insect pests are not easy to identify, thus lengthening At the time of counting, the data obtained is also not accurate enough. For this reason, it is very necessary to carry out the research on the law of trapping insect pests by using insect forecasting lamps.
Pest report lamp is a new type of lamp with modern technology, pest detection tools, with automatic switching, far-infrared parasite treatment, automatic conversion of insects, temperature measurement, humidity measurement, automatic printing and other functions. At present, it is mainly used for the prediction and prediction of rice pests. The installation of insect report lamp in the field was strictly in accordance with the requirements. All machines were fixed on square bases 600 mm in height and 1100 mm in width, and the installation positions were all in the middle of a paddy field. The time of attracting insects is March 1 to December 31 every year. The original black light (incandescent) lamp was used as a control. A survey and statistics were conducted on rice pests trapped by Jiaduo bug-reporter lamps and ordinary black-light (incandescent) lamps every 5 years. They were recorded at the beginning and end of the period, respectively. Statistical adults were at their peak and female adults were at their peak and adult population. Peak day and female adult peak day.
The insect report lamp is slightly earlier or same than the ordinary black light (incandescent) lamp trapping rice main pests rice leaf roller, whitebacked planthopper, brown planthopper, and borer borer. Accounted for 84.2%; the end-stage period was slightly late or the same, and the late-end stage or the same frequency accounted for 79%. The short-term forecast accuracy of the insect report light is 1.65% to 8.66% higher than the average black light (incandescent) lamp, an average increase of 3.56%. It is an ideal forecasting tool and can replace ordinary black light (incandescent) lamps without affecting the continuity of the observation data. Comparability.
