越北腹露蝗触角感器的扫描电镜观察

应用环境扫描电镜(ESEM)对越北腹露蝗FruhstorferiolatonkinensisWill.触角的外部形态进行观察的结果表明,蝗蝻和成虫触角均分布有以下6种感器,毛形感器、刺形感器、锥形感器、栓锥形感器、腔锥形感器和Bhm氏鬃毛,其中锥形感器有长、短锥之分,腔锥形感器有Ⅰ、Ⅱ型之分。芽孢形感器、盾形感器和钟形感器只限于蝗蝻的触角。成虫触角鞭节末端长锥形感器数量多于蝗蝻;而蝗蝻触角鞭节末端短锥形感器数量多于成虫。成虫触角从第9节开始,蝗蝻触角从第11节开始锥形感器和腔锥形感器的数量明显增多。

The ultra-structure of sensilla in antennae of Fruhstoferiola tonkinensis

Ultra-structure of sensilla on antennae of the grasshopper Fruhstoferiola tonkinensis Will. was observed with an environmental scanning electron microscope (ESEM). Six kinds of sensilla of antennae were found in both adult and nymph: sensilla trichodea, sensilla chaetica, sensilla basiconca, sensilla styloconicum, sensilla coeloconicum and Bhms' bristles. Sensilla basiconca could be divided to two types: long type (L) and short type (S), and sensilla coeloconicum also had two types, but sensilla sporangium, sensilla scutellatum and sensilla comaniformium were only found in antennae of the nymph. On the terminal section of antennae, the density of sensilla basiconca (L) was higher in adult than in nymph, and the density of sensilla basiconca (S) was higher in nymph than in adult. Sensilla basiconca and sensilla coeloconicum had a higher density on the terminal of antenna from the ninth section in adult and the eleventh section in nymph.
