每年10月中、下旬至11月上、中旬以后,水稻黄熟,气温降低,褐稻虱雌虫寻觅田边游草等多种嫩茎杆,中空或内部组织疏松的部位产“越冬卵”,在避风保湿,有较高湿度条件,及靠近水稻地方较多。 经4年调查,已知褐稻虱的越冬产卵寄主,有6科20种:禾本科的游草、千金子、红茎马唐、旱稗、看麦娘、光头稗、双穗雀稗、雀稗等,莎草科的水虱草、水蜈蚣、荣蔺、荆三稷等;玄参科的母草、陌上蕃椒;木贼科的笔形草;鸭跖草科的水竹叶;雨久花科的鸭舌草等。产后大部分卵以各级发育期保持到次年,只有少量孵出。
From mid-October to late November and mid-November each year, the rice is yellow-ripe and its temperature is lowered. The brown planthopper looks for a variety of tender stalks, such as grassy fields, and hollows or internal loose tissues produce “wintering eggs” Humidity in the shelter, high humidity conditions, and more places near the rice. After 4 years of investigation, it is known that the overwintering spawning host of the brown planthopper, there are 6 families and 20 species: Poaceae grass, gall gold, red stem crab, Adenophora, Anemarrhena, barnyard grass, Paspalum , Paspalum, Cyperaceae water lice grass, water centipede, Rong Lin, Jing three millet; Scrophulariaceae motherwort, Mo Shang pepper; Equisetaceae pen-shaped grass; Commelinaceae water bamboo leaves; Kurashiki such as Monochoria. Postpartum most of the eggs to all levels of development to maintain the following year, only a small amount of hatch.
