摘要：

粟灰螟以幼虫为害。早期为害谷子幼苗,钻进髓部,破坏生长点,造成枯心,以致全株生机停顿,枯萎而死。在有分蘖品种,分蘖虽可照常生长,但产量也不免减低。後期在茎内蛀食,但此时谷子已经抽穗,养分仍可经由茎外部导管向上输送,无白穗现象,为害远不如早期的严重。

摘要：

1. The millet stem borer is a destructive insect pest in North China. Itcauses damage to the seedlings of millet which become twisted and die as a resultof primordial destraction. 2. This insect overwinters mainly in the millet stubble as larva. The over-wintering period lasts from the middle of September to the middle of Maynext year. 3. The mortality at the end of the overwintering period was found to be57.0% and 74.6% in the years 1951 and 1952 respectively. 4. The first moth, appeared on May 21, 1951 and May 15, 1952.flight of the overwintering moths lasts about 40 days. 5. Eggs are laid in masses. During oviposition the female prefers a smoothsurface to a less smooth one. Large egg masses are always found on smoothsurfaces. One female can lay as many as 173 eggs. Hatching percentage wasfound to be 72.5% on the average. 6. There are three generations a year. The first generation larvae causethe most severe destruction to the millet seedlings. The second generation larvaeare unimportant economically due to the high rate of parasitism. As much as93.4% of them were parasitized at the end of July, 1951. Increase in borerpopulation occurs in the third generation.
