Ultrastructure of Haller's organ in the tick Amblyomma americanum (L.) [PDF]
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1972 Haller's organ on the tarsus of the tick Amblyomma americanum (L.) (Acarina: Ixodidae; nymphal stage) was studied by scanning and transmission electron microscopy. It consists of a distal bristle group, (the “anterior pit”), and a proximal “capsule” which encloses several sensilla. The seven sensilla of the anterior pit (A1–A7) are all thick-walled and
