棉花红铃虫(Pectinophora Gossypiella Saunders.)是华中棉区首要的害虫,每年普遍发生,棉花遭受损失一般在2、3成以上,也是限制两熟棉区棉花产量与品质提高的主要因素。以往本棉区对红铃虫缺乏系统的研究,对红铃虫发生与发展的规律基本上不够了解,因而不能达到有计划扑灭红铃虫灾害。若盲目喷药,则将造成成本高、增产效果不显著的不良影响。四年(1951—1954)来,我们针对着红铃虫间题,在武昌和松滋两地进行了系统的红铃虫生活规律的研究,同时布置越冬和大田药剂防治试验,现将初步结果提供出来以便进一步的研究。 Cottonseed bollworm (Pectinophora Gossypiella Saunders.) Is the most important pest in the cotton fields in Central China. It is a common pest in cotton fields in the Central China every year. The loss of cotton is generally above 2,3%, which is also a major factor limiting the yield and quality of cotton in the two cotton fields. In the past, the lack of systematic research on the pink bollworm in the present cotton area basically did not understand enough about the occurrence and development of pink bollworm and could not achieve the goal of eliminating the pink bollworm calamities. If the blind spraying, it will result in high costs, the effect of increasing production is not significant adverse effects. In the fourth year (1951-1954), we conducted a systematic study on the law of life of the pink bollworm in Wuchang and Songzizi, and conducted experiments on the prevention and control of overwintering and field pesticides. The preliminary results Available for further research.
