1959年以来朱深甫先生就各世代红铃虫在棉株上产卵部位的研究曾作过报道,并对调查方法作了阐述。60年代以来,随着棉花种植方式的改变,棉花生育期提早,结铃期提前,青铃上二代红铃虫着卵率增高。一般年份在90%以上,迟发年份在70—80%。目前采用的调查方法中,从二代起查中下部青铃的卵粒,对其它部位上的着卵数量无法查证,尤其在棉花迟发年份,所查青铃卵量与实际全株卵量间误差较大。本试验为掌握棉株结铃数量与红铃虫产卵部位的关系,以便解决这一矛盾。
Since 1959, Mr. Zhu Shenfu has reported on the spawning sites of cotton bolls on various generations of red bollworm and elaborated on the survey methods. Since the 1960s, with the change of cotton planting methods, the growth period of cotton was earlier and the period of bolting earlier. More than 90% of the general year, late 70-80%. Currently used in the survey method, from the second generation check the lower part of the egg green bell, the other parts of the egg number can not be verified, especially in the cotton late years, the number of checked green bell eggs and the actual total number of eggs Between the larger error. In order to solve the contradiction, this experiment is to understand the relationship between the boll number of cotton bollworm and spawning sites of pink bollworm.
