- Around the food, as the peritrophic membrane of an insect's alimentary canal.
Sorry, no etymologies found.
So they wrap it up, and some parasites cannot get out of this layer that we call peritrophic matrix, or peritrophic sac.
The research also showed that Hessian fly midguts are lacking a peritrophic membrane, a common insect feature that protects the microvilli from toxic substances.
Because CHSA is responsible for chitin synthesis in the cuticle and trachea and CHSB mainly for chitin synthesis in the peritrophic matrix in the gut
Mueller CR, Fuchs JF, Wessely V, Lan Q, et al. (2006) Regulatory mechanisms of chitin biosynthesis and roles of chitin in peritrophic matrix formation in the midgut of adult
Arakane Y, Muthukrishnan S, Kramer KJ, Specht CA, Tomoyasu Y, et al. (2005) The Tribolium chitin synthase genes TcCHS1 and TcCHS2 are specialized for synthesis of epidermal cuticle and midgut peritrophic matrix.
In addition to the peritrophic matrix and exoskeleton, these findings confirm chitin is also present in the mosquito serosal cuticle.
TcCHSB) is the major/sole contributor to the chitin synthesis in peritrophic matrix chitin synthesis
