褐稻虱Nilaparuata lugens(Stal)是水稻上的重要害虫之一,近十几年来大发生频次明显增加。目前国内多数学者认为“盛夏不热,晚秋不凉”是其暴发的气候型相,并认为盛夏高温对褐稻虱的发生有抑制作用,但高温对褐稻虱发育繁殖的影响实质,以及各虫态的耐热性所见报道不多。本试验用不同高温和时间处理褐稻虱各虫态,然后观察其对褐稻 Nilaparuata lugens (Stal) is one of the most important pests on rice, and its occurrence frequency has increased significantly in recent ten years. At present, most domestic scholars believe that “no heat in midsummer, late autumn is not cool” is the outbreak of the climate phase, and that high temperatures in midsummer have an inhibitory effect on the occurrence of brown planthopper, but the high temperature on the brown planthopper development and reproduction of the essence, as well as Insects in the state of heat seen little. In this experiment, the different states of brown planthopper were treated with different temperature and time, and then the brown rice was observed
