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.

Reproductive Status of Boll Weevils During Season and Off‐Season of Cotton in the Cerrado of Brazil

Entomologia Experimentalis et Applicata, Volume 174, Issue 2, Page 113-122, February 2026.
Cotton boll weevils were monitored continuously and counted weekly over two agricultural years in the Brazilian Cerrado. The survey resulted in a total of 94 519 adults captured in approximately similar percentages of females and males during both the growing and off‐seasons.

Aedes fluviatilis cell lines as new tools to study metabolic and immune interactions in mosquito-Wolbachia symbiosis

Scientific Reports, 2021
In the present work, we established two novel embryonic cell lines from the mosquito Aedes fluviatilis containing or not the naturally occurring symbiont bacteria Wolbachia, which were called wAflu1 and Aflu2, respectively.
