Agricultural and forestry pests are major threats that hinder agricultural development and negatively impact both the yield and quality of crop products. To reduce pesticide residues in crops and ensure the safety and quality of agricultural produce, at the end of June this year, Peixian Xie Xin Family Farm—located in Tongchang Village, Weimiao Town—was the first in the county to introduce solar-powered insecticidal lamps, effectively controlling crop diseases and pests.
　　Not long ago, a reporter visited the Xiexin Family Farm in Peixian County. The rice fields were on the verge of harvest, and 20 solar-powered insect-killing lamps stood silently at the edge of the fields, vigilantly "standing guard" over the fertile land—much like sentinels—while the collection bags beneath them were already brimming with the pests they had eradicated.
　　“These aren’t your typical lighting lamps—they’re solar-powered insecticidal lights designed to control pests in the fields.” When it comes to these solar insect traps, technician Li Zhongcheng becomes unusually excited. “Not only do these lights effectively lure and eliminate rice pests like brown planthoppers and stem borers, as well as cereal pests such as armyworms and wheat moths, but they can also automatically turn on during clear nights and shut off automatically during sunny days and rainy weather—no manual operation required!”
　　According to Li Zhongcheng, the solar-powered insecticidal lamp uses a solar panel as its primary power source. During the day, it stores the electricity generated from sunlight, and at night, it releases this stored energy to power the insect-killing device. The lamp exploits pests' natural tendencies—such as phototaxis, wave attraction, and color preference—to lure them toward the light source. Outside the light source, a high-voltage killing grid is strategically placed to zap the insects on contact, guiding them into a specially designed collection bag, thereby achieving the goal of eliminating pests. "Though you may not notice the lamp's effectiveness during the day, it truly works wonders at night," Li Zhongcheng explains. "It’s almost like a magnet, drawing pests straight into their doom."
　　Around 8 p.m. as night fell, the glow of the solar-powered insect-killing lamps was particularly striking. Pests flying in from afar were instantly zapped and killed by high-voltage steel wires positioned near the lamp tubes. Standing beside one of the solar insect traps, the reporter noticed that the sticky insect-catching net was already covered with dead pests. "These insects were all collected over the past few days," Li Zhongcheng explained to the reporter as he carefully sorted through the bag beneath the lamp, extracting the captured bugs one by one.
　　“Who would have thought that a tiny insecticidal lamp could be of such great help to me!” Farm owner Zheng Maodong exclaimed when talking about the benefits of the insecticidal lamp. “This effective, physics-based pest-control method not only saves labor and reduces costs—but most importantly, it significantly lowers pesticide residues, ultimately improving the quality of our rice.”
