Agathidinae is a subfamily of braconid parasitoid wasps. Some species have been used in biological control programs. [1]
Agathidines are among the larger braconids, and diurnal members of this subfamily are often brightly patterned. They belong to the noncyclostome group.[ citation needed ] Several genera, such as Agathis, Cremnops and Disophrys , are characterized by elongate genae. [1]
Agithidines can be recognized by the following combinations of features: forewing veins M + CU not tubular in basal third or more, forewing vein RS complete to the wing margin (except Mesocoelus and Plesiocoelus), occipital carina absent, and second submarginal cell of forewing usually present (90% of species.) [1]
They are found worldwide, but are more diverse in the tropics. However, some genera such as Agathis and Earinus are more speciose in temperate regions. [1] [2]
Most Agathidines are solitary koinobiont endoparasitoids of concealed Lepidoptera larvae. However, the tribe Disophrini attacks free living Lepidoptera larvae. The tribes Agathidini and Earinini attack the first and second instar larvae of their hosts, contrasting with the Disophrini, which attack later instars, as well as the Cremnoptini, which parasitize every larval stage. Most species are diurnal, but many Disophrini are nocturnal, with pale coloration and enlarged ocelli. [1]
The first attempt at a tribal arrangement for Agathidinae consisted of 2 tribes, Agathidini and Microdini. Sharkey revised the tribes in 1992 and considered 5 tribes, adding Cremnoptini, Disophrini, and Earini. The Microdini, then treated as Eumicrodini, was synonymized under Agathidini by Simbolotti and van Achterberg in 1999 to render 4 tribes. Phylogenetic analysis by Sharkey and Chapman in 2017 revealed that 4 tribes were insufficient and instead divided the subfamily into 7 tribes. They further found that the genera Asperagathis, Bassus, and Zosteragathis were not monophyletic. One problematic species, the Nearctic Bassus annulipes , was found to represent a complex of species. Further, Bassus annulipes was rendered under the tribe Lytopylini while the Old World species fell under Agathidini. [3]
Agathidines have been used for biological pest control. Notable examples include Agathis pumila for the western larch case-bearer, Alabagrus stigma for the sugarcane borer, and Bassus unicoloratus for the potato tuberworm. [1]
The 63 genera placed here include: [4] [3]
The Braconidae are a family of parasitoid wasps. After the closely related Ichneumonidae, braconids make up the second-largest family in the order Hymenoptera, with about 17,000 recognized species and many thousands more undescribed. One analysis estimated a total between 30,000 and 50,000, and another provided a narrower estimate between 42,000 and 43,000 species.
The Aphidiinae are a subfamily of tiny parasitoid wasps that use aphids as their hosts. Several species have been used in biological control programs of various aphids.
Microgastrinae is a subfamily of braconid wasps, encompassing almost 3,000 described species, with an estimated 30,000–50,000 total species. This makes it one of the richest subfamilies with the most species of parasitoid wasps.
The Doryctinae or doryctine wasps are a large subfamily of parasitoid wasps within the family Braconidae.
The Euphorinae are a large subfamily of Braconidae parasitoid wasps. Some species have been used for biological pest control. They are sister group to the Meteorinae.
The Alysiinae are a subfamily of braconid parasitoid wasps with over 1000 described species. Several species have been used in biocontrol programs. They are closely related to the Opiinae.
The Rogadinae are a large subfamily of braconid parasitoid wasps. Several Rogadinae species parasitize pest caterpillars and are important for naturally occurring biological control.
The Cenocoeliinae are a subfamily of braconid parasitoid wasps.
Apozyx is a genus of braconid parasitic wasps with only one species, Apozyx penyai. It is the only genus in the subfamily Apozyginae. This subfamily was originally proposed as a separate family by Mason in 1978.
The Cardiochilinae are a subfamily of braconid parasitoid wasps. This subfamily has been treated as a tribe of Microgastrinae in the past. Some species including Toxoneuron nigriceps have been used in biocontrol programs.
Dirrhope is the only extant genus in the subfamily Dirrhopinae of braconid parasitoid wasps. Dirrope was included in the Microgastrinae until 1984. Specimens of this genus have been found fossilsed in amber dating from the Cretaceous period.
Aerophilus is a genus of parasitoid wasps belonging to the family Braconidae. As members of the subfamily Agathidinae, they are koinobiont endoparasitoids of caterpillars. The host is attacked as an early instar, but not consumed and killed until the host is about to pupate. Nearly all species of Aerophilus have a narrow host range, attacking only one caterpillar species. However, the host range of the genus as a whole is quite broad, including many families of Lepidoptera.
Blacini is a tribe of braconid Parasitoid wasps.
Lytopylus is a genus of parasitoid wasps in the family Braconidae. As members of the subfamily Agathidinae, they are koinobiont endoparasitoids of caterpillars. This genus is primarily found in the neotropics, but ranges from the northeastern United States to Argentina. There are 39 species of Lytopylus, and many more undescribed.
Brachistinae is a subfamily of braconid wasps in the family Braconidae.
Wroughtonia is a genus of braconid wasps in the family Braconidae. There are over 40 described species in Wroughtonia.
Helconinae is a subfamily of braconid wasps in the family Braconidae.
The Acampsohelconinae are a subfamily of braconid parasitoid wasps. Extant members of this subfamily were previously included in the Helconinae, Blacinae, or Sigalphinae. The four genera included are †Acampsohelcon, Afrocampsis, Canalicephalus, and Urosigalphus.
Sigalphinae is a subfamily of braconid wasps, containing 8 genera and less than 50 described species.
