Reproductive Performance of Bracon hebetor1 Females with More or Fewer than the Normal Number of Ovarioles2

By: R. Petters n & D. Grosch n

topics (OpenAlex): Insect and Arachnid Ecology and Behavior; Physiological and biochemical adaptations; Insect Utilization and Effects
TL;DR: Wasps with fewer than 4 ovarioles produced proportionately fewer eggs than their “normal” 4-ovariole sisters, and in females with 5–9 ovariolaes, egg production did not increase significantly, suggesting the supply of vitellogenic materials is a limiting factor. (via Semantic Scholar)
