Diachasmimorpha longicaudata (Ashmead) is a koinobiont endoparasitoid of Tephritidae larvae. In its habitat of origin, D. longicaudata. Diachasmimorpha longicaudata originated from the Indo-Pacific region, has been widely disseminated into America via Hawaii, and can be considered. Host Preference by Diachasmimorpha longicaudata (Hymneoptera: Braconidae) Reared on Larvae of Anastrepha fraterculus and Ceratitis capitata (Diptera.

Taiwan—small scale field releases Yao Diachasmimorpha longicaudata is one of the most intensively studied species used in the biological control of Tephritidae. Occipital carina well developed; ventral margin of clypeus completely concealing labrum when mandibles closed.

Females lay eggs per day using her elongated ovipositor to reach the fly larvae.

The gaster of males and females differs slightly with the female having a dorsal central black band while the gaster of the male has a dark brown to black dorsal posterior. Host vibrations cue to host location by the parasite, Biosteres longicaudatus.

Having found rotting fruit, the female parasite can detect the larvae by sound. Florida, USA —introduced in against A. It has been introduced to Hawaii, Florida, Latin America, and elsewhere, where it attacks fruit-infesting tephritids in other genera such as Anastrepha Schiner and Ceratitis MacLeay.


Diagnosis and Relationships markup Diachasmimorpha longicaudata and Diachasmimorpha dacusii are distinguished largely by apparent differences in hosts but this situation needs further investigation see the dacusii page.

Although this classical biological control technique is effective in reducing Caribbean fruit fly populations, it is not an eradication technique.

Effects of parasite density and host availability on progeny production by Biosteres Opius longicaudatus Hym.: Mass parasite releases would further suppress the wild fly population while posing no threat to property or the environment. The body is a reddish-brown color and antennae are longer than the body. The gaster of the male often has dark brown to black dorsal posterior segments.
