前人的研究曾指出,三化螟内部生殖系统的发育及幼虫的龄期龄数、历期与取食不同生育期的水稻有关。据认为这是由于不同生育期茎内的含醣量和含氮化合物不同所致。还有人观察到,由于取食不同的水稻品种,三化螟虫体内营养物质的积累不同,致使越冬幼虫的体重有显著差异,这是直接关系到冬后种群数量变动的基本因素,如越冬死亡率及雌蛾抱卵量等。
Previous studies have pointed out that the development of the reproductive system inside the stem borer larvae and the number of age groups, the duration and feeding different growth stages of rice. It is considered that this is due to the different growth stages of the stem of the sugar content and nitrogen compounds due to different. It has also been observed that due to the different rice varieties fed on, the accumulation of nutrients in the stem borers is different, resulting in significant differences in the body weight of overwintering larvae, which are directly related to the changes in winter population after the basic factors such as overwintering mortality And female moths and so on.
