Ibis, EarlyView.High colour variability in animals has been associated with adaptability to environmental change. Establishing how such variability is distributed in time and space, and identifying environmental correlates, can help understand the processes driving it.

Melanization and Tyrosinase Activity
Journal of Investigative Dermatology, 1971 Purified soluble tyrosinase isolated from the melanosomes of Harding-Passey mouse melanoma was incubated with L-dopa. The reaction velocity of the tyrosinase thus incubated decreased significantly. There was an inverse linear relationship between the concentration of dopa in the preincubation mixture and the reaction velocity of the tyrosinase which ...

Sperm reduces female longevity and increases melanization of the spermatheca in the bumblebee Bombus terrestris L [PDF]
, 2018 .: Here we present evidence that the male mating products (sperm and gland products) reduce survival during hibernation of queens of the bumblebee B. terrestris.

Insecticidal activity of a basement membrane-degrading protease against Heliothis virescens (Fabricius) and Acyrthosiphon pisum (Harris) [PDF]
, 2008 ScathL is a cathepsin L-like cysteine protease derived from the flesh fly Sarcophaga peregrina that functions in basement membrane (BM) remodeling during insect development.

Journal of Zoology, EarlyView.The Urban Heat Island Effect (UHI) can potentially subject insects to heat and desiccation stress and likely induce shifts in their cuticular hydrocarbon (CHC) profile. We expected that warmer urbanized areas favour longer chain length of hydrocarbons as well as higher abundance of n‐alkanes in three Hymenoptera species. We found that temperature, more

Prophenoloxidase activation is required for survival to microbial infections in Drosophila.
PLoS Pathogens, 2014 The melanization reaction is a major immune response in Arthropods and involves the rapid synthesis of melanin at the site of infection and injury. A key enzyme in the melanization process is phenoloxidase (PO), which catalyzes the oxidation of phenols ...

Plant Biotechnology Journal, EarlyView.ABSTRACT Candidatus Liberibacter asiaticus (CLas), the causative agent of citrus Huanglongbing (HLB), is transmitted by Asian citrus psyllid, Diaphorina citri; however, the role of the insect's immune effectors in defending against CLas remains poorly understood. This study reveals that D.
