Hence, larvae treated with these insecticides cannot shed their exocuticle. This might be what led to the mortality of larvae fed with teflubenzuron treated feed in the present study.

Insecticidas reguladores del crecimiento para el control del escarabajo de la cama Alphitobius diaperinus (Coleoptera: Tenebrionidae)

Produced by the underlying epidermal cells, the cuticle is composed of four layers (from outer to inner): epicuticle, exocuticle, endocuticle, and membranous layer (Travis and Friberg, 1963b; Raz et al., 2002).

Reciprocal changes in calcification of the gastrolith and cuticle during the molt cycle of the red claw crayfish Cherax quadricarinatus

Molt stages were based on the criteria of Drach and Tchernigovtzeff (1967) and Norman and Jones (1992): 1) soft, no calcification of the new exoskeleton; 2) early papershell, thin, flexible exoskeleton, easily depressed when touched; 3) late papershell, hard exoskeleton except for the branchiostegite region which is compressible; 4) intermolt, completely hard exoskeleton; and 5) premolt, teeth on chelae well worn and having a less rounded appearance compared with those in earlier stages, complete exocuticle developed beneath the exoskeleton.

Nocturnal occurrence of the swimming crab Ovalipes punctatus in the swash zone of a sandy beach in northeastern Japan

These cells apparently secrete the pharyngeal cuticular intima, consisting of three layers: the lamellate endocuticle, the exocuticle with trabeculae-bound spaces and the thin epicuticle lining the luminal surface.

A transmission electron microscopic study of the pharyngeal armature in the larval Drosophila Melanogaster

Category 1 is the least severe erosion, with shallow lesions extending into the epicuticle and exocuticle. The lateral edges of the lesions often exhibited evidence of melanization, but inflammation in the underlying connective tissue or other evidence of an immune response is rarely observed at this stage.

Dysbiosis in epizootic shell disease of the American lobster (Homarus americanus)

anisopliae had enough space to grow laterally in the cuticle, assimilate the nutrients obtained from the cuticle degradation, and spread between the exocuticle and the endocuticle without being in direct contact with the hemocytic activity of the hemocoel.

2a): the epicuticle, the procuticle comprised of the exocuticle and endocuticle, and the innermost epidermis.

Several bundles of muscle (M) just above the exocuticle are evident from their strong acidophilia after staining with hematoxylin and eosin.

Loss of the epicuticle would expose the protein and chitin-rich exocuticle, consistent with significantly higher peptidase potentials in lesions versus HS and HL shell samples, as well as the loss of the protein/lipid matrix seen in scanning electron microscopy (Smolowitz et al.
