@article{jensen_silverman_2018, title={Frequently mated males have higher protein preference in German cockroaches}, volume={29}, ISSN={["1465-7279"]}, DOI={10.1093/beheco/ary104}, abstractNote={Protein is an abundant nutrient in sperm, and males therefore expend protein every time they mate. In addition, many males provide the female with a nitrogen-rich nuptial gift during mating, which often increases female fertility by supplementing her pool of limiting nutrients. However, it is unknown whether males compensate for the nitrogen cost of mating by increasing their preference for protein, which would facilitate the production of new sperm and nuptial gift material. Using artificial diets, we investigated whether male German cockroaches (Blattella germanica) would compensate for nitrogen expenses of mating by increasing protein preference when given the opportunity to self-select their diet from complementary foods differing only in protein and carbohydrate content. We distributed adult males across 4 mating regimes differing in the frequency of mating opportunities with receptive females and measured protein and carbohydrate consumption as well as reproductive output over the lifespan of each male. Receptive females were either never available (no mating opportunity), or they were available overnight at a frequency of each 28 days (rare mating opportunities), each 14 days (occasional mating opportunities), or each 7 days (frequent mating opportunities). Males selected highly carbohydrate-biased diets. However, males that mated more frequently had higher consumption and reproduction and self-selected higher lifetime protein to carbohydrate ratios. Our study demonstrates that male German cockroaches actively select a more protein-biased diet that compensates for their nutritional requirements following mating. The study shows that male mating significantly affects foraging decisions for specific nutrients to compensate for the expenses of mating.}, number={6}, journal={BEHAVIORAL ECOLOGY}, author={Jensen, Kim and Silverman, Jules}, year={2018}, pages={1453–1461} }

We investigated the effect of foraging distance on individual German cockroaches by providing two foods differing in protein-to-carbohydrate ratio at opposite ends of long containers or adjacent to each other in short containers. Each food was nutritionally imbalanced, but the two foods were nutritionally complementary, allowing optimal foraging by selective feeding from both foods. We measured nutrient-specific consumption in fifth instar nymphs and newly eclosed females foraging at the two distances, hypothesizing that individuals foraging over longer distance would select more carbohydrate-biased diets to compensate for the energetic cost of locomotion. We then determined dry mass growth and lipid accumulation in the nymphs as well as mass gain and the length of basal oocytes in the adult females as an estimate of sexual maturation. Nymphs foraging over longer distance accumulated less lipid relative to total dry mass growth, but contrary to our predictions their protein intake was higher and they accumulated more structural mass. In concordance, adult females foraging over longer distance gained more body mass and matured their oocytes faster. Our results show a positive effect of foraging distance on fitness-related parameters at two life stages, in both cases involving increased consumption of specific nutrients corresponding to requirements at the respective life stage.}, number={2}, journal={The Journal of Experimental Biology}, publisher={The Company of Biologists}, author={Ko, Alexander E. and Jensen, Kim and Schal, Coby and Silverman, Jules}, year={2016}, month={Nov}, pages={304–311} }
