Lysiphlebus is a genus of parasitoid wasps belonging to the family Braconidae.[1]

The genus has a near cosmopolitan distribution.[1]

Species:[1]

Reproduction

Most Lysiphlebus species are haplodiploid, like other Hymenoptera.[2] However, all-female lineages are common in some Lysiphlebus-taxa including L. fabarum, L. cardui and L. confusus.[3]

In these asexual lineages, females can reproduce by a parthenogenetic mechanism, i.e. thelytoky, that involves automixis with central fusion.[4]

The genetic system underlying sex determination in Lysiphlebus is "complementary sex determination", similar to the cape honey bee (see Haplodiploidy § Sex determination in honey bees).[5] Unlike honey bees, however, the Lysiphlebus complementary sex determiner gene is thought to be present in multiple copies.[6]

Asexual females may occasionally produce diploid males, which when mated with sexual females, can convert sexual into asexual lineages, a process which has been dubbed "contagious parthenogenesis".[7]

Ecology

Like other Aphidiinae, Lysiphlebus are endoparasitoids of aphids. They lay their eggs inside the body of aphids, where their larvae develop, eventually spinning a mummy-like cocoon inside its remains.[8]

Most Lysiphlebus species specialize in attacking ant-defended aphid colonies.[8] They avoid attack by the ants through chemical mimicry of the aphid cuticular hydrocarbons.[9]
