电镜扫描观察表明:友恩蚜小蜂雌蜂触角具有毛形感觉器、板形感觉器、钟形感觉器、指形感觉器和B hm氏鬃毛等5种感觉器.上颚发达,左、右上颚各具3根毛形感觉器;下颚须和下唇须各1节,在末端和近末端1/3处,分别具1根刺形感觉器.同时还探讨了各种感觉器的功能.

The antennal sensilla of female Encarsia amicula were studied by scanning electron microscope, and the results showed that there were five sensilla, namely, trichoid seusilla, placoid sensilla, campanifonn sensilla, finger-like sensilla and BShm bristles, on the antennae of En. amicula. The mandibles are wen-developed and each mandible bears 3 trichoid sensilla on its outer aspect.
