| morphology and histology of secretory setae in terrestrial larvae of biting midges of the genus forcipomyia (diptera: ceratopogonidae). | apneustic larvae of the genus forcipomyia possess unique secretory setae located on the dorsal surface along the body in two rows, one pair on each thoracic and abdominal segment and two pairs on the head. morphological and histological studies of secretory setae in fourth instar larvae of forcipomyia nigra (winnertz) and forcipomyia nigrans remm indicate they are modified mechanoreceptors (sensilla trichodea) in which the trichogen cell is a glandular cell producing a hygroscopic secretion. the ... | 2011 | 21978824 |
