赤斑黑沫蝉的发生与防治

Occurrence and Control of Callitettix versicolor Fabricius

经 1998～ 1999年的仔细观察、系统调查研究 ,初步掌握了赤斑黑沫蝉的习性及危害特点。通过试验、示范 ,提出一套防治措施。即 :冬耕田土、清除四周杂草 ,冬前和春后深挖田埂、土坎杀伤卵粒 ;在卵盛孵期 (泡沫大量出现时 )用以敌氧菊酯复配剂为主的药剂防治若虫 ,在成虫盛期分别在玉米和水稻上用敌氧菊酯复配剂进行统防统治 ;在玉米施返青肥时 ,根施 3%呋喃丹颗粒剂 ,在水稻施返青肥时 ,撒施

The habit and damaging characteristic of Callitettix versicolor Fabricius were initially known through observation and investigation, A set of control method was put forward by the experiments and demonstrations. The measurements included ploughing fields and weeding in winter, digging baulks deeply for killing eggs before winter and after spring, controlling nymphs at the hatching period with “di yang ju zhi”, an insecticide, (emergence of plenty of foam), controlling adults on plants of maize and rice with“di yang ju zhi” at the full adult stage and applying 3% “fu nan dan” to plants of maize and rice with the revival fertilizers.
