The Central Nervous System

The stomodaeal nervous system in Aedes aegypti (L.) possesses a frontal, a hypocerebral, and two ventricular ganglia. It innervates parts of the alimentary tract and some muscles of ingestion, and it has associated with it certain motor nerves from the central nervous system, and sensory nerves. In larvae these sensory nerves originate from tactile head hairs, and from sensilla on the epipharyngeal apparatus. The neurosecretory system is generally similar to that in other insects. The pars intercerebralis contains three paired groups of neurosecretory cells, with axons from one pair leading to the dorsal mass, a structure fused to the hypocerebral ganglion. Evidence suggests that the dorsal mass functionally corresponds to part of the corpus cardiacum of other insects. However, what seem to be cardiacum cells are located some distance away in two groups in the endocrine gland complex in the thorax. The corpora allata, also contained in this complex, can first be recognized as distinct organs early in the third instar. In the corpora allata of adult females, cell division and an increase in the amount of cytoplasm occur soon after emergence, rather than after a blood meal. When adult females are about 1 day old, vacuoles begin to develop in the corpora allata. Cells in the gland complex corresponding to the prothoracic gland cells begin to histolyze in the pupa, and most of them are completely broken down before adults are 1 day old.

The life cycle of Anilocra pomacentri, an ectoparasitic isopod that infests the pomacentrid fish Chromis nitida, in the southern section of the Great Barrier Reef, is described in detail. Embryonated eggs developed through four ontogenic stages within the brood pouch (marsupium) of adult females. Released mancas were free-swimming and infective immediately to suitable hosts. Mancas were negatively buoyant and displayed strong negative rheotaxis and positive phototaxis. The appendix masculina that characterises the male stage was found on isopods between 4.1 and 7.2 mm in telson length. Males developed into females and remained attached permanently to their hosts. Adult females produced an average of three broads during their lifespan of 12-14 months. The number of mancas (average 3.2 mm in telson length) in each brood positively correlated with the telson length of the parent and ranged from 37 to 182. Isopod telson length was correlated positively with fish caudal fork length, which indicated that early infection of the host was followed by simultaneous growth of both host and parasite. In laboratory trials mancas fed successfully on small (14-29 mm length to caudal fork) C. nitida. Infection of larger fish was limited to transient attachment of mancas to the fins. Adult female isopods fed on host blood, with feeding limited to only those periods that correlated with the onset of vitellogenesis. Fish that carried feeding isopods showed a significant reduction in the number of circulating erythrocytes.
