利用扫描电镜对锈翅蚁蛉Myrmeleon ferrugineipennis Bao&Wang雌雄成虫头部触角及口器感器的形态进行观察,描述了感器的种类、数量和分布,以期解析其取食机制。结果表明:锈翅蚁蛉触角上存在10种感器,即毛形感器、锥形感器、刺形感器、腔形感器、钟状感器、鳃形感器、耳形感器、盘形感器、舌形感器和Bhm氏鬃毛,其中毛形感器有3种亚型,数量最多;耳形感器、腔形感器和钟状感器仅在雌成虫触角上发现,而舌形感器和鳃形感器仅在雄成虫触角上发现;在锈翅蚁蛉触角鞭节近末端扁平匙状处各有1枚盘形感器,其形状和位置在雌雄虫上有差异。鳃形感器和盘形感器在已有的昆虫感器研究中未见报道,是新发现的昆虫触角感器。下颚须、下唇须上均发现锥形感器,下唇须上的数量多于下颚须;此外,下颚须上还存在钟状感器。
Scanning electron microscopy (SEM) was used to observe the antennal and antennal sensilla of Myrmeleon ferrugineipennis Bao & Wang, describing the species, number and distribution of sensilla, in order to analyze the feeding mechanism. The results showed that there are 10 kinds of sensilla on the antennae of the rickety ant, namely, hairy sensor, cone sensor, thorn sensor, cavity sensor, bell sensor, gill sensor, ear sensor , Disc-shaped sensor, tongue-shaped sensor and Bhm’s mane, among which there are three subtypes of hairy sensor, the largest number; ear sensor, cavity sensor and bell sensor only in female adults Found on the antennae, while the tongue-shaped sensor and gill-shaped sensor only found on the male antennae; in the rusty ant anthus tentacles near the end flat spoon-shaped spoon each have a disc-shaped sensor, its shape and location in the There are differences between male and female. Gill-shaped sensor and disc-shaped sensor in the existing insect sensor research has not been reported, is the newly discovered insect antenna sensor. Lower jaw whisper, lower lip should be found on the tapered sensor, the lower lip to be more than the number of lower jaw; In addition, there must be bell-shaped sensor on the jaw.
