Bruchophagus
seed chalcid, gall wasp
Bruchophagus is a genus of chalcid wasps in the family Eurytomidae. Species within this genus are primarily seed-feeders, developing in the seeds of plants in the Fabaceae family, though some species form galls on citrus or other hosts. The genus has a cosmopolitan distribution and includes economically significant pests such as the alfalfa seed chalcid (B. roddi) and citrus gall wasp (B. fellis). Recent phylogenomic studies indicate the genus is paraphyletic.
Pachylobius
pine weevils
Pachylobius is a genus of pine weevils in the family Curculionidae, established by LeConte in 1876. The genus contains at least two described species: Pachylobius picivorus (pitch-eating weevil) and Pachylobius stupidus. Species in this genus are associated with coniferous hosts and have been documented as pests of pine regeneration in forest ecosystems.
Xylotrechus sagittatus sagittatus
Xylotrechus sagittatus sagittatus is a subspecies of longhorn beetle in the family Cerambycidae, tribe Clytini. It is a pine-associated wood-boring beetle found in southeastern North America, with its distribution extending to the northern limits in Arkansas. The species exhibits strong behavioral responses to olfactory cues, particularly ethanol and turpentine in a 5:1 ratio, and visual cues play a secondary role in host-finding behavior. Adults are attracted to stressed or dying pine trees and have been documented responding to elevated traps.
