Abstract

Study of collections from Texas and Oklahoma yielded specimens of an undescribed species in the genus Brachys Dejean very similar to and previously confused with Brachys ovatus (Weber). Brachys wellsoi Hespenheide, new species is described, illustrated, and compared with previously known species.

Abstract

Distributional information is presented for Megaderus bifasciatus Dupont, 1836, a rare species of longhorned beetle in the cerambycid tribe Trachyderini. Valid occurrence records from Mexico and Central America are listed, and enigmatic historical records for the southwestern United States are examined to attempt to determine their veracity. An inventory of specimens found in museum collections is documented. The records for Texas and Arizona are examined, and the likelihood that the species is, or ever was, present in the United States is discussed.

Abstract

1. Specialist seed-feeders are widely used in weed biological control, but seed predation rates are frequently insufficient to cause the required impacts. Understanding the underlying reasons is prerequisite to predicting efficacy.

2. We conducted continental-scale surveys of an introduced, multi-voltine seed-feeder [Bruchidae: Penthobruchus germaini (Pic.)] on an invasive legume (Caesalpinaceae: Parkinsonia aculeata L.). We tested three hypotheses as to what limits seed predation; namely, seed escape through egg aggregation, mortality of immature beetle stages, and failure to track temporal fluctuations in resource availability. We also tested how these factors interacted with the environment and each other.

Abstract

In 2012 an infestation of unfamiliar seed beetles was discovered in eastern California feeding within the seeds of Mexican palo verde (Parkinsonia aculeata). These turned out to be a species native to South America, Penthobruchus germaini (Coleoptera: Chrysomelidae: Bruchinae).
