Toxin resistance in the monarch butterfly expanded its milkweed host range

Naama C. Weksler, Michael Astourian, Derrick Yip…·Marianthi Karageorgi

This study shows that toxin resistance in monarch butterflies allowed them to expand their milkweed host range by enabling survival on a broader range of cardenolide-defended plants.

Beneficial reversal of dominance maintains a resistance polymorphism under fluctuating insecticide selection

Marianthi Karageorgi, Anastasia S. Lyulina, Mark C. Bitter…·Dmitri A. Petrov

The paper shows that beneficial reversal of dominance at the Ace locus in Drosophila melanogaster allows resistant alleles to persist under fluctuating insecticide selection.
