The mechanism by which sexual reproduction is lost is of great importance35. Diplodiploid cyclically parthenogenetic aphids might lose sex through alterations of periodicity genes or genes that regulate hormonal expression36. This can happen so easily that a third of aphid species might be combinations...
In this review, we outline the complex life cycles of adelgids, and current status and recent advances in adelgid life cycle studies. We also discuss the evolution of adelgid life cycles by comparing them to closely related aphid life cycles. A switch from holocycly to anholocycly on the ...

The Hard Graft of Grapegrowing Grape phylloxera is a tiny pale yellow, aphid like insect from the Phylloxeridae family, within the Hempitera order of bugs. It was described in the 1860s crisis in France asPhylloxera vastratix(devastator of vines), and later found to be the same as the ...
Amino acids had a positive effect on both aphid species abundance, but neither condensed tannins nor auxiliary insects seemed to modulate aphid populations. Interestingly, the leaf carbohydrate content was positively correlated with the abundance of A. spiraecola, but not with that of A. gossypii. ...
This review is aimed to discuss the current state of art in aphid genomics focusing in particular on the aspects that could improve our knowledge of their evolution. Introduction Aphids are small plant-sucking insects, many of which are very important as agricultural pests, not only in view of...
Genome Evolution Mitochondrial genome Introduction Aphids are well-known phloem-feeding pests of agriculture, reducing yields in some crops by up to 50% [1]. Of the nearly 5,000 known aphid species (Hemiptera: Aphidoidea), among which approximately 450 feed on crop plants, more than 100 are...
A phylogenetic analysis of these changes showed that let-7 targets have evolved rapidly in primates in comparison to other species (Fig. 2). The pattern of miRNA-mRNA target evolution differed among the three described miRNA families and even between the two rapidly evolving families (Supplementary...
