Trissolcus Oenone
''Trissolcus oenone'' is a parasitoid wasp in the family Platygastridae, native to Australia and New Zealand. It parasitises the eggs of Pentatomidae, stink bugs (Pentatomidae), but little is known about its biology. Description ''Trissolcus oenone'' is a small black wasp, 1–2mm in length (depending on host), and shares many morphological similarities with other Australian ''Trissolcus'' species. The New Zealand population can generally be separated from other New Zealand ''Trissolcus'' species based on the colour of parasitised eggs, and the colour of the legs and antennae. Pentatomid eggs parasitised by ''Trissolcus oenone'' develop a black ring near the top of the egg, whereas those parasitised by ''T. basalis'' turn almost entirely black. Adult specimens of ''T. oenone'' have black patches on the bases of the legs, while ''T. basalis'' legs are uniformly orange. Ecology ''Trissolcus oenone'' is very common in Australia where it is known to parasitise the eggs of ''Bip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platygastridae
The hymenopteran family Platygastridae (sometimes incorrectly spelled Platygasteridae) is a large group (over 4000 species) of exclusively parasitoid wasps, mostly very small (1–2 mm), black, and shining, with geniculate (elbowed) antennae that have an eight-segmented flagellum. The wings sometimes lack venation, though they may have slight fringes of setae. The traditional subfamilies are the Platygastrinae and the Sceliotrachelinae. The former subfamily includes some 40 genera, all of which are koinobionts on cecidomyiid flies; the wasp oviposits in the host's egg or early instar larva, and the wasp larva completes development when the host reaches the prepupal or pupal stage. The latter subfamily is much smaller, including some 20 genera, and they typically have the rudiments of a vein in the forewings. They are generally idiobionts, attacking the eggs of either beetles or Hemiptera. Platygastridae is one of seven extant families in the superfamily Platygastroidea. F ...
