| 中文摘要: |
| 对柑橘大实蝇成虫羽化期、田间消长规律及活动习性的研究，结果表明：1、三个观察点成虫羽化始见日至羽化高峰的时间都在5-10天左右，羽化期为16-19天，2011年麻阳的成虫始见日和羽化高峰期比2010年提前了5-8天，2011年长沙的羽化始见日和羽化高峰期都比麻阳稍早2-4天。2、成虫从羽化至基本死亡共持续84天。成虫在田间的始见日和高峰期分别处在5月下旬和6月中下旬，2010年成虫的田间始见日和高峰期都比2011年迟5至7天。3、成虫在交配产卵前，很少飞往柑橘树上，而在橘园及周围杂草或灌木丛中觅食、栖息；当气温超过30℃，成虫飞往橘园周边高大乔木或草丛中避暑，下午16∶00以后飞往柑橘树上产卵。 |
| 英文摘要: |
| To study the emergence period , occurrence in field and action of Tetradacus citri Chen adult in Hunan. Results show that, 1. the time between the earliest date and crest-time of adult appearing was about 5-10 days ,the time of emergence period was 16-19 days. the earliest date and crest-time of adult appearing moved forward by 5-8 days from 2010 to 2011 in Mayang; compared to Mayang, it moved forward by 2-4 days in Changsha. 2.it lasted 84 days from the emergence period to the adult death. The time between the earliest date of adult appearing in field was in late May, while the crest-time was in mid to late June. The earliest date and crest-time of adult appearing moved forward by 5-7 days in field from 2010 to 2011. 3. Few adult flew to the citrus trees before mating and spawning, feeding and resting near the orangery and weeds; adult would fly to the high tree or weeds near the orangery when the temperature surpasses 30℃, and spawn in the citrus trees after 16: 00. |
