Özet:

 


The use of color patterns with pigments, such as melanin, play a vital
role for various functions in insects including sexual behavior, warning
coloration, and camouflage. Cuticular melanin appears to be under some genetic
and environmental selection in many species and, melanin is also a crucial
component in cuticular hardening, wound healing and invertebrate immunity.
Melanin and its precursors provides a protection against a wide range of
pathogens (including bacteria, fungi, animals and viruses) in insects.
Cuticular melanism and some innate immune responses can share common
physiological pathways in insects. Phenoloxidase
(PO), a key enzyme in the synthesis of melanin, is found in the haemolymph,
midgut and cuticle. When an insect host is confronted with a
hemocoel-bound pathogen, it encapsulates the invading organism with hemocytes
(encapsulation response). The hemocytes degranulate to release a tyrosinase
phenoloxidase, which converts tyrosine to L-DOPA and several other diphenol
quinones. These substrates are eventually transformed into melanochrome, which
non-enzymatically converts to melanin. In this review, importance of the
melanisation process in insect pyhsiology especially in melanin-based innate
immunity responses is highlighted. Additionaly, a special attention is given
the importance of the thermal melanin hypothesis, which is tightly associated
with melanin-based immune investment within the context of global climate
change.
