Lysiphlebus fabarum (Marshall)
Geographical distribution: Hosts: Various aphids (Aphididae).
Morphology: The female is mostly brown-black, about 1.3-1.8 mm in length, the leg segmnets are yellow and black.
Life cycle: A female produces about 120 eggs when parasitizing A. fabae. The eggs are inserted into the host’s hody and the larva develops therein. The host becomes mummified after a few days and completes its development within the mummy. A generation is completed in 2-3 weeks. L. fabarum feeds on the honeydew excreted by the aphid hosts and may mimic attending ants.
Economic importance: An important endoparasitoid of various pestiferous aphids, like Aphis craccivora, Aphis fabae and Toxoptera aurantii. At times this parasitoid may destroy all aphids that infest citrus tress. Mummified aphids can be stored for several weeks at low temperatures for release in the field.
