    • In this manuscript, we elucidated the genetic mechanisms underlying high levels of desiccation resistance in a desert species, D. mojavensis.

    • We identified a fatty acyl CoA elongase gene in D. melanogaster, Dmel/mElo, which is responsible for the elongation of methyl-branched cuticular hydrocarbons (mbCHCs).

    • We showed that the ability to synthesize longer mbCHCs is due to evolutionary changes in the protein-coding region of mElo

    • mElo knockout in D. mojavensis led to the loss of longer mbCHCs and reduction of desiccation resistance at an ecologically relevant temperature.

    • mElo is a Drosophila-specific gene, suggesting that while the physiological mechanisms underlying desert adaptation may be similar between species, the genes involved in these mechanisms may be species or lineage specific.

    • ​In this study, we investigated how the evolution of cuticular hydrocarbons determines variation in desiccation resistance in Drosophila species. 

    • Using Drosophila species from diverse habitats, we showed that variations in the composition of cuticular hydrocarbons (CHCs), a hydrophobic layer found on insects to prevent evaporative water loss, can largely explain desiccation resistance differences.

    • The evolution of longer methyl-branched CHCs (mbCHCs), underlies the evolution of higher desiccation resistance in this genus.

    • As mbCHCs are ubiquitously present in most insects, we suggest that evolutionary changes in mbCHCs may be a general determinant of desiccation resistance across insect species.

    • ​In this study, we investigated the thermal tolerance of an invasive insect pest in the US, the crapemyrtle bark scale (CMBS). We found this pest can tolerate high temperatures in the summer while having limited tolerance to the cold.

    • Based on its cold tolerance, we designed a computational pipeline to predict how far north this invasive species can spread in the US. [See our prediction in the figure below.]

    • The cold hardiness of crapemyrtle [the red line], the main host plant of CMBS, is the same as the predicted northern distribution of CMBS [the black line].  We suggest this pest can spread to all areas in the US where crapemyrtles were planted.

    • In this paper, we investigated how the physiology of CMBS changes over the season and contributes to its seasonally altered cold tolerance. 

    • This is the first study of cold tolerance mechanisms in the superfamily Coccoidea.

    • Reduced body water content and increased energy reserve were found in winter CMBS.

    • Short-chain fatty acids accumulated in triacylglycerol in winter CMBS.

    • D-Mannitol is the major cryoprotectant.

    • In this study, we showed that CMBS cannot only attack crapemyrtles, but also other plants in the US including American beautyberry, pomegranate, henna, sinicuichi, and winged loosestrife (from left to right in the picture below).
