To determine how maternal and paternal larval diets influence offspring development time, adult body size, and pathogen resistance in Drosophila melanogaster.
Reared parental generation fruit flies on either a standard or poor larval diet.
Mated adult flies across all four sex-by-parental diet combinations.
Assessed offspring development time, adult body size, and adult survival following infection with the bacterium Serratia marcescens.
Females reared on poor larval food produced larger offspring than standard-fed females, and fathers reared on poor food sired larger male progeny.
Development time was longest when both parents received a poor diet and shortest when parents experienced discordant diets (one parent standard, one poor).
Parental larval diet produced no detectable transgenerational effects on offspring resistance to Serratia marcescens infection.

Implication

Laboratory study reveals parental larval malnutrition increases offspring body size and alters development time in Drosophila melanogaster, indicating sex-specific transgenerational dietary effects.
