Biosteres
Biosteres is a genus of parasitoid wasps in the family Braconidae, first described by Förster in 1862. Species in this genus are solitary or gregarious endoparasitoids, primarily attacking larvae of tephritid fruit flies. Several species, including B. longicaudatus, B. arisanus, and B. tryoni, have been extensively studied for their use in biological control programs against economically important fruit pests. The genus has an almost cosmopolitan distribution, with species documented across Europe, Asia, North America, and other regions.

Blacini
Blacini is a tribe of braconid parasitoid wasps within the subfamily Brachistinae. Members are minute, dark-colored wasps with distinctive non-cyclostome mouthparts and a carina along the posterior head margin. The tribe was elevated from subfamily status in 2011 based on molecular phylogenetic evidence. The genus Blacus dominates the tribe with approximately 40 described New World species and cosmopolitan distribution, while remaining genera are largely restricted to South and Central America.

Blacus chillcotti
Blacus chillcotti is a species of parasitoid wasp in the family Braconidae, described by van Achterberg in 1976. Members of the genus Blacus are known as parasitoids of beetle larvae, particularly those in the family Curculionidae (weevils). The species is part of the diverse ichneumonoid wasp radiation, which contains thousands of species specialized in biological control of insect pests. Specific details about B. chillcotti remain limited in published literature.

Blissus occiduus
Western Chinch Bug
Blissus occiduus, the western chinch bug, is a phloem-feeding true bug (Hemiptera: Blissidae) that is a significant pest of warm-season turfgrasses, particularly buffalograss and zoysiagrass. The species exhibits strong host preference hierarchies, with buffalograss being the most preferred host followed by zoysiagrass, though it can survive and reproduce on a broad range of grasses including agronomic crops. Field studies have documented inconsistent control with neonicotinoid insecticides, with thiamethoxam showing particularly rapid degradation in buffalograss tissues compared to imidacloprid and clothianidin.

Bombyliidae
bee flies, bomber flies
Bombyliidae is a large family of true flies comprising over 4,500 described species across approximately 270 genera. Adults are commonly known as bee flies due to their frequent resemblance to bees, often achieved through dense body hair and Batesian mimicry. They are important pollinators, particularly in arid environments, with some species possessing proboscises longer than their bodies to access deep floral tubes. Larvae are parasitoids or predators of other insects, with hosts including solitary bees, wasps, beetles, and other arthropods. The family has a cosmopolitan distribution but reaches greatest diversity in tropical and subtropical arid regions.
