摘 要：
调查结果说明：①晋棉２６号对二代棉铃虫抗性极强，在棉铃虫中度发生和大发生年份，不喷药或仅喷药１次，可将棉铃虫控制在防治指标以下；②晋棉２６号对三代棉铃虫仍有较强抗性，虽然抗性有所下降，但在中度以上发生年份，仅喷药防治２～４次，可将棉铃虫控制在防治指标以下。

摘 要：
During 19961997, field investigation was conducted in Yongji and Linyi county. Results indicated that Jinmian 26 showed strong resistant to cotton bollworm of second generation. Under years of moderate and heavy incidence, cotton bollworms were controlled below prevention index with no spraying or spraying only one time. Jinmian 26 also showed certain resistance to bollworm of third generation; though resistance had some decrease, under years of moderate incidence, the pests were brought under control with spraying 24 times.
