摘要
采用扫描电子显微镜对花蓟马Frankliniella intonsa(Trybom)、禾花蓟马F.tenuicornis(Uzel)和西花蓟马F.occidentalis(Pergande)3种国内危害严重的农业害虫的两性成虫触角感器超微结构进行观察和比较,旨在明确3种花蓟马两性成虫触角上的感器类型、数量、分布及超微形态特征,明晰3种花蓟马触角感器差异,进而补充蓟马感器详细资料、完善蓟马形态学研究。结果表明:3种花蓟马两性成虫触角上均有8种感器类型,即B(o|¨)hm氏鬃毛、钟形感器、毛形感器、刺形感器、锥形感器、腔锥形感器、腔开感器和特殊结构感器。触角各节上感器的分布和数量并不均匀。分析结果显示,各类感器在触角上的分布相对稳定,具有一定规律;近缘种间和同种两性间触角感器的形态及分布无明显差异。
The type, number, distribution and ultra-morphology of antennal sensilla of both genders in three Frankliniella thrips, i. e., Frankliniella intonsa （Trybom）, F. tenuicornis （Uzel） and F. occidentalis （Pergande）, which are serious agricultural pests in China, were observed and compared using scanning electron microscopy. Through the morphological observation and comparison, we hope to clarify the differences of sensilla among these species, supplement the detail information of thrips sensilla and perfect the researches on thrips morphology. The results showed that there are eight types of sensilla on the antenna of every species, i. e., B？hm bristles, sensilla campaniformia, sensilla trichodea, sensilla chaetica, sensilla basiconica, sensilla coeloconica, sensilla cavity and unusual sensillum. The number and distribution of sensilla are uneven on each antennal segment. The analysis results revealed that every type of sensilla has a relatively stable distribution pattern, and there is no significant difference among closely-related species or between sexes.
