The peritrophic membrane (PM) in larvae of the southern corn rootworm Diabrotica undecimpunctata (Coleoptera:Chrysomelidae) forms along the full length of the midgut epithelium, defining D. undecimpunctata as a Type I insect with respect to PM format

Developmental changes in Malpighian tubule fluid transport were studied using in vitro and in situ preparations from timed larval, pupal and adult skipper butterflies (Calpodes ethlius). The ability to transport fluid and the rate of fluid secretion

The control of developmental changes in Malpighian tubule cell structure and fluid secretion by 20-hydroxyecdysone and juvenile hormone in the skipper butterfly Calpodes ethlius were studied using (1) in vitro tissue culture, (2) in vivo injection an

Insect tracheae grow and deposit new cuticle at each moult. The increase in diameter of the new tracheae over the old can be used as an index of growth. At the last larval-larval moult in Calpodes the diameter of the lateral tracheae doubles from 110

1. 1. Na + -K + ATPase occurs in skate but not in dogfish intestinal brush borders. 2. 2. EGTA and EDTA must be included in the enzyme assay mixture to detect Na + -K + ATPase in skate intestinal brush borders. 3. 3. Preliminary results suggest that

Relatively little is known about the structure or function of the basal lamina in insect cells. I report here the ultrastructural organization of the basal lamina in Malpighian tubule yellow region primary cells of larval stage skipper butterflies (C

Gap junctions are intercellular junctions found in both vertebrates and invertebrates through which ions and small molecules can pass. Their distribution in tissues could be of critical importance for ionic coupling or metabolic cooperation between c
