The seasonal emergence of Culicoides furens (Poey) has been studied for about 15 months. Three presently important habitats of this species, namely tidal ditches, brackish pools, and impoundments, were observed for comparison. The pattern of emergence from impoundments differed from the other 2 habitats in that relatively few adults were produced early in the year with the onset of warmer weather (March to June), but the rate of emergence continued at a higher level into the beginning of the “winter” months and was generally higher throughout the cold period (September to March). Tidal ditches and brackish pools yielded most adults early in the year, with numbers generally diminishing through the summer and falling sharply to a low level throughout the cold period. The emergence patterns are interpreted in terms of the number of generations completed annually and in light of other data concerning seasonal size change and potential for autogenous development of eggs. Data obtained concurrently with the main study indicated that light traps may provide incomplete information about the seasonal emergence of C. furens .

Culicoides furens（双翅目：Ceratopogonidae）在佛罗里达州维罗海滩的季节性出现

Culicoides furens (Poey) 的季节性出现已被研究了大约 15 个月。观察了该物种目前三个重要的栖息地，即潮沟、咸水池和蓄水池，以进行比较。蓄水区出水模式与其他 2 个生境不同，随着天气转暖（3 月至 6 月），在年初生产的成虫相对较少，但出水率继续保持较高水平，直到“冬季”月份，在整个寒冷时期（9 月至 3 月）普遍较高。潮沟和咸水池在年初产出了大多数成年人，数量在整个夏季普遍减少，并在整个寒冷时期急剧下降到低水平。根据每年完成的代数以及有关季节性大小变化和鸡蛋自体发育潜力的其他数据来解释出现模式。与主要研究同时获得的数据表明，光阱可能提供有关 C. furens 季节性出现的不完整信息。
