TL;DR: It is discovered that infection with a facultative endosymbiont of the genus Rickettsiella changes the insects’ body color from red to green in natural populations of the pea aphid.

TL;DR: In this article, two red pigments, uroleuconaphins A1 (1) and B1 (2), were isolated from the aphid Uroleus nigrotuberculatum (Olive), and their absolute configurations were determined by single-crystal X-ray analysis of their derivatives.

TL;DR: A modified version of Marko's aerobic oxidation procedure, using highly pure (99.995+%) CuCl with 4,7-diphenyl-1,10-phenanthroline (dpPhen ), DBAD, and Cs 2 CO 3 (98% purity), successfully oxidized primary and secondary alcohols to the corresponding aldehydes and ketones in excellent yield at room temperature with either air or molecular oxygen under atmospheric pressure as mentioned in this paper.

TL;DR: A novel naphtho[2,3-c]furan-4(1H)-one derivative 1, named furanaphin, was isolated from the aphid A. spiraecola and found to have cytotoxicity against HL-60 human tumor cells.

TL;DR: Four novel yellowish pigments were isolated from the aphid Uroleucon nigrotuberculatum (Olive) and their structures were established by detailed analyses of 1D and 2D NMR spectra and mechanistic consideration of the interconversion between 3 and uRoleuconaphin A 1 ( 1 ) (or B 1 ( 2)).
