Agricultural insect herbivores show a remarkable ability to adapt to modern agroecosystems, making them ideal for the study of the mechanisms underlying rapid evolution. The mobilization of transposable elements is one mechanism that may help explain this ability. The Colorado potato beetle, Leptinotarsa decemlineata, is a highly adaptable species, as shown by its wide host range, broad geographic distribution, and tolerance to insecticides. However, beetle populations vary in insecticide tolerance, with Eastern US beetle populations being more adaptable than Western US ones. Here, we use a community ecology approach to examine how the abundance and diversity of transposable elements differs in 88 resequenced genomes of L. decemlineata collected throughout North America. We tested if assemblages and mobilization of transposable elements differed between populations of L. decemlineata based on the beetle's geography, host plant, and neonicotinoid insecticide resistance. Among populations of North American L. decemlineata, individuals collected in Mexico host more transposable elements than individuals collected in the United States. Transposable element insertion locations differ among geographic populations, reflecting the evolutionary history of this species. Total transposable element diversity between L. decemlineata individuals is enough to distinguish between populations, with more TEs found in beetles collected in Mexico than in the United States. Transposable element diversity does not appear to differ between beetles found on different host plants, or relate to different levels of insecticide resistance.
