二化螟的群体饲养已向两方面发展,即用人工饲料和稻苗的饲养。用稻苗进行二化螟的群体饲养比较简便。兹将基本条件、饲养方法分述于下: 养虫室 需要的条件是:温度28±1℃;相对湿度60％;光照用2000米烛光的萤光灯,保持15小时的光照期以防止幼虫休眠。 饲养瓶 带金属旋盖的玻璃瓶,直径11厘米,高9厘米。为了通气和为螟虫提供化蛹场所,在盖上开一个直径2厘米的孔,并用棉花塞塞住。
Chilo suppressalis breed has been developed to two aspects, namely the use of artificial feed and rice seedling feeding. Breeding rice stem borer population with rice is relatively simple. Here are the basic conditions, feeding methods are described below: Insects room required conditions are: temperature 28 ± 1 ℃; relative humidity 60%; light with 2000 m candle light fluorescent lamp, to maintain a 15-hour light period to prevent larvae Sleep. Rearing bottle Glass bottle with metal capping, diameter 11 cm, height 9 cm. To aerate and provide a pupal site for the stem borer, a 2 cm diameter hole was opened in the lid and plugged with a cotton plug.
