Red flour beetles have been known to readily infest wheat flour but their likelihood to choose other types of flours is unknown. Red flour beetles will lay eggs in many types of flours but their choice to infest low- and no-gluten flours remains to be tested. Here we test a panel of 14 different commercially available flours in three different choice assays. We find that the beetles lay similar amounts of eggs in buckwheat, teff, millet, rice, and rye flours but that they show significant declines in preference for sorghum, potato, quinoa, cassava, oat, amaranth, garbanzo, spelt, and corn flours.

This dataset contains manual annotations from Rhyzopertha dominica community curators, based on genome assembly RdoDt3_Drdd8_decomES.fasta.gz. These annotations are direct exports from Apollo 2.6 (https://doi.org/10.5281/zenodo.5015109), hosted by the i5k Workspace@NAL (https://i5k.nal.usda.gov/). Manual annotations are temporary and will be reviewed by the i5k Workspace@NAL and submitted to NCBI's GenBank database after review.

Data collected from early Sep 2020 - Jun 2021 for two experiments: (1) mobility of Tribolium castaneum and Rhyzopertha dominica after exposure to differently formulated controlled release materials for 0-60 min, and (2) median lethal time after exposure to cheesecloth treated with permethrin, deltamethrin, indoxacarb, and dinotefuran between 0-168 h. Tested strains include phosphine-resistant and phosphine-susceptible populations.
