| 中文摘要: |
| 为明确温度对美洲斑潜蝇和南美斑潜蝇种间竞争的影响，在试验玻璃筒中同时接入两种斑潜蝇各1♀1♂，置于不同温度（18、25、30 ℃）下培养，观察两种斑潜蝇子代的化蛹数、成虫数及羽化率。结果显示，18 ℃下，美洲斑潜蝇的F1代成虫数仅为（0.4±0.3）头，显著低于南美斑潜蝇的（2.5±0.7）头；25 ℃下，美洲斑潜蝇的F1代成虫数（7.6±3.0）头，稍高于南美斑潜蝇的（4.3±2.0）头，但不存在显著差异；30 ℃下，美洲斑潜蝇的F1代成虫数为（18.0±2.9）头，而F1代中无南美斑潜蝇成虫。说明温度对两种斑潜蝇的种间竞争具有重要影响。 |
| 英文摘要: |
| The pupae, adults and percentage of adult emergence were evaluated by putting L. sativae (1♀:1♂) and L.huidobrensis (1♀:1♂) into glass tubes at different temperatures (18, 25, 30 ℃) to study the effects of temperature on interspecific competition and displacement between Liriomyza sativae and L.huidobrensis.The results showed that there was significant difference in the number of F1 adults between L. sativae (0.4±0.3) and L. huidobrensis (2.5±0.7) at 18 ℃; at 25 ℃, the number of L. sativae adults (7.6±3.0) were more than that of L. huidobrensis adults (4.3±2.0) in F1 progenies, but had no significant difference; at 30 ℃,there were only L. sativae adults (18.0±2.9) in F1 progenies. The results indicated that temperature was a key factor in interspecific competition between the two leafminer species. |
