Gonadulin and Insulin‐Like Growth Factor Involved in Rhipicephalus microplus Reproduction

Entomologia Experimentalis et Applicata, Volume 174, Issue 3, Page 285-295, March 2026.
Insulin‐like growth factor (IGF2) in ovaries of Rhipicephalus microplus partially engorged females. Ovaries from females at different feeding stages were used to detect IGF2. ABSTRACT Gonadulin and insulin‐like growth factor (IGF) are neuropeptides synthesized by the central nervous system (CNS) of arthropods.
