稻虱红螯蜂触角感受器的扫描电镜观察

Scanning electron microscopic observation of the antennal sensilla of Haplogonatopus japonicus

扫描电镜观察表明,稻虱红螯蜂Haplogonatopus japonicus Esaki et Hashimoto触角上存在6种感受器,其中刺形感器、锥形感器Ⅳ型、柱形感器Ⅱ型和Bhm氏鬃毛雌、雄都有,仅数量和分布上存在差异;毛形感器Ⅱ型、Ⅲ型,锥形感器Ⅰ型、Ⅱ型、Ⅲ型,柱形感器Ⅰ和锥形乳头状感器仅分布于雌蜂触角;而毛形感器Ⅰ型,锥形感器Ⅴ型仅见于雄蜂触角。对触角感受器的形态进行了描述,并对部分感器功能进行了讨论。

Six types of sensillum on the antenna of Haplogonatopus japonicus Esaki et Hashimoto were found by scanning electron microscopy.Chaetic,basiconic sensillumⅣ,cylindricⅡand Bhm＇s bristles occurred in both sexes,but each sensilla differed in number and location between male and female.TrichoidⅡ,Ⅲ,basiconic sensillumⅠ,Ⅱ,Ⅲ,cylindricⅠand basiconic mastoid sensillum were only found on female＇s antenna.Trichoid sensillumⅠand basiconic sensillumⅤwere only found on emale＇s antenna.The shapes of these were described and parts of their function were discussed in the article.
