Farnesoic acid O-methyl transferase (FAMeT) isoforms: conserved traits and gene expression patterns related to caste differentiation in the stingless bee, Melipona scutellaris.

abstract：:Destruxins have been implicated in the infection process by entomopathogenic fungi and have been also found to be highly toxic when applied topically or ingested by different insect species. To gain insight into the mechanism of action of this toxin on insect internal organs, we have evaluated the effects of destruxin...

abstract：:Among insects, lifespans vary over a broad range, from the short-lived mayflies to the 17-year periodical cicadas. Generally, lifespans are determined by a phase in life, the reproductive lifespan, which varies among species. Numerous pathways, such as the insulin/insulin-like growth factor signaling pathway, the targ...
