澳洲大蠊触角感受器的扫描电镜观察

Observation on the antennal sensilla of Periplaneta australaslae Fabricius with scanning electron microscope

目的获得澳洲大蠊触角感受器外部形态的资料,并与美洲大蠊和黑胸大蠊的触角感受器进行比较,为蟑螂的防治提供新的基础资料。方法扫描电镜观察法。结果观察结果表明,大蠊属昆虫的触角均分布有毛形感器、刺形感器和锥形感器,澳洲大蠊同时还有腔锥形感器。结论澳洲大蠊触角感受器种类较为丰富。

Objective To obtain fine morphological structures of antennal sensilla of Periplaneta australaslae, to compare with ones of P. americaua and P. fuliginosa, and to provide some new basic data for the cockroach control. Methods Scanning electron microscope （SEM） method. Results Three common types of sensilla were found on the all these antennae, including sensilla triehodea, sensilla chaetiea and sensilla basieonca. Conclusion Forms of antennal sensilla of P. australaslae are abundant.
