Functional Characterization of Two RNA Methyltransferase Genes and Uncovers the Roles of mA in Mediating Adaptation of to Host Plants.

-methyladenosine (mA) is one of the major epigenetic modifications in eukaryotes. Although increasing functions of mA have been identified in insects, its role in L. for host plant adaptation remains unclear.

Fitness comparison of on original and marginal hosts using age-stage, two-sex life tables.

The diamondback moth, , is an important agricultural pest that severely damages cruciferous vegetables. Although previously considered a threat only to species, has been observed to feed on noncruciferous vegetables. Here, we established a population of on the pea (PxP population).
