| 为了解掌握山西晋南各地小地老虎越冬代成虫发生量与海拔、气温、降雨等环境因子的关系, 2015年进行了不同环境条件下小地老虎越冬代成虫性诱剂诱虫试验。结果表明:低海拔地区的成虫比高海拔地区始见期早, 且发生量大；成虫始见期温度为5~6℃, 活动的高峰期温度为11~19℃, 终末期温度为25~28℃, 低于5℃或者高于28℃成虫基本不活动或零星活动；在成虫主要集中活动的11~19℃范围内, 不同区域成虫活动与温度变化差异显著, 温度高时活动明显加剧, 温度低时活动减弱；成虫的发生量随降雨量增加呈递减规律; 从降雨前1日到降雨当日再到雨后1日也整体呈递减规律, 但中雨前后3日, 发生规律有所不同, 呈“V”字形趋势；其中, 小雨(或阵雨)当日及前1日、中雨前1日的平均单日诱虫量均大于无雨日的诱虫量。 |

| The experiments were conducted to study the relationships between the occurrence quantity of the overwintering generation of Agrotis ipsilon and the environmental factors. Sex attractant was used to evaluate the effects of environmental factors on occurrence and overwintering of A. ipsilon in three sites in southern Shanxi Province. The result showed that the initial appearance period and the occurrence quantity were earlier and lager at lower altitudes than higher altitudes. The minimum, optimal, and maximum growth temperature were 5-6℃, 11-19℃, and 25-28℃ for A. ipsilon moth, respectively. When the temperature was lower than 5℃ or higher than 28℃, the adults were not active or sporadically active. At 11-19℃, the higher the temperature was, the more active the adults were. The number of A. ipsilon moth was sharply changed at the day before the raining day, raining day, and the next day. Therefore, the occurrence quantity of A. ipsilon moth was closely related to altitude, temperature, rainfall, and other environmental factors. |
