摘要:
研究了新疆亚洲玉米螟Ostrinia furnacalis(Guenée)不同地理种群在(27±1)℃的恒温条件下,光照时数为4~20 h之间时的光周期反应.结果表明,光周期和不同地理区域对亚洲玉米螟幼虫发育历期有极显著性影响,两因素交互作用对亚洲玉米螟幼虫发育历期有极显著性影响.焉耆、塔城、昌吉种群的临界光周期为LD14:10 h,乌鲁木齐、哈密种群的临界光周期为LD15:9 h.新疆不同地理种群亚洲玉米螟在光照时间时数为8~12 h之间时幼虫的发育历期最长,滞育诱导率最高.并且光照时数长于14 h时,随着光照时数的增加,反而幼虫发育历期缩短,滞育率降低.光周期和亚洲玉米螟发育历期负相关,即光照延长,亚洲玉米螟幼虫发育历期缩短.不同地理区域和亚洲玉米螟发育历期正相关,即北纬度升高,亚洲玉米螟幼虫发育历期延长.

Abstract:
This paper studies the photoperiodic reaction of different geographic populations of Xinjiang Asian corn borer Ostrinia furnacalis (Guenée) under the conditions of constant temperature (27±1℃) and an illumination time of 4-20 h. The results show that photoperiodic period, different geographical regions and their interaction have a significant influence on the growth period of Asian corn borer larvae. The critical photoperiod is LD14:10 h for the Yanqi, Tacheng and Changji populations, and LD15:9 h for the Urumqi and Hami populations. The larvae of different geographical populations of Asian corn borer in Xinjiang have the longest developmental duration and the highest rate of diapause induction with an illumination hour of 8-12 h. When the illumination time is longer than 14 h, their developmental duration is shortened and their diapause rate decreases with increasing sunshine hours. The developmental duration of Asian corn borer larvae is correlated positively with photoperiod and negatively with latitude.
Key words:  Ostrinia furnacalis|diapause rate|critical photoperiod|developmental duration
