Alysiinae

Alysiinae are small wasps, usually under 5 mm long and black or brown in color. The mandibles are exodont, opening outwards and not overlapping—a characteristic essentially unique among braconids, with only rare exceptions in the genus Exodontiella (subfamily Gnamptodontinae).

Frequently observed wherever decaying organic matter occurs.

Worldwide distribution. Documented from Iran (78 species, 15 genera), India (67 species, 13 genera), Finland (numerous species including 91 Dinotrema species), Australia, Papua New Guinea, Korea, Argentina, and other regions.

• Cyclorrhapha Diptera - koinobiont endoparasitoidFemales oviposit into host eggs or larvae; host allowed to develop until puparium formation
• Drosophila - parasitoidPhaenocarpa persimilis parasitizes several cosmopolitan and native Drosophila species
• Drosophilidae - larval parasitoidAsobara tabida is a larval parasitoid of Drosophilidae

Females oviposit into host eggs or larvae. The host is allowed to develop until it forms a puparium, at which point it is killed by the wasp larva. The Alysiinae larva then pupates within the host puparium. Adults use their exodont mandibles to break free of the tough host puparium.

Most species are solitary, but a few are gregarious and lay multiple eggs within one host. Adults use exodont mandibles to break free of host puparia.

Parasitoid wasps regulating populations of Cyclorrhapha Diptera, particularly in decaying organic matter habitats.

Several species have been used in biocontrol programs. Phaenocarpa persimilis has been investigated for laboratory rearing and potential as an efficient parasitoid for biological control.
