Brachistinae
Guides
Nealiolus
Nealiolus is a genus of parasitoid wasps in the family Braconidae, subfamily Brachistinae. The genus comprises nine described species, with three occurring in the Neotropical region. Members are specialized parasitoids of stem-boring and fruit-boring weevils (Curculionidae), including significant agricultural pests such as the sunflower stem weevil and cotton boll weevil. The genus has recognized potential as a biological control agent due to its host specificity and high parasitism rates.
Schizoprymnus
Schizoprymnus is a genus of braconid parasitoid wasps in the subfamily Brachistinae, comprising 126 extant species distributed worldwide except the Neotropical region. Species are ovo-larval koinobiont endoparasitoids of coleopterous larvae, particularly weevils and related beetle families. The genus is characterized by a distinctive carapace formed by the fusion of the anterior three metasomal tergites.
