Cotesia Urabae
''Cotesia urabae'' is a small (2.5–3.2 mm long) wasp, having a black body with yellow-brown legs, characterized by a solitary larval endoparasitoid stage (Austin and Allen, 1989). It is part of a large complex of 11 primary parasitoids of ''Uraba lugens ''Uraba lugens'', the gum-leaf skeletoniser, is a moth of the family Nolidae. It is found in Australia and New Zealand. The larvae are a serious pest of ''Eucalyptus'' species and their close relatives. The wingspan is 25–30 mm. In Austr ...'' Walker, many of which are polyphagous (Allen, 1990a, 1990b). The female inserts its ovipositor into the a ''U. lugens'' larva, depositing its eggs there, and it has been found that one female may carry up to 400 eggs (Allen, 1989). While ''C. urabae'' females are able to attack the same larva several times; only one single parasitoid completes its development in each larva (Berndt, 2010). Once the ''C. urabae'' larvae emerges from the host larvae, a tightly woven sulphur-y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasitoid
In evolutionary ecology, a parasitoid is an organism that lives in close association with its host (biology), host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionarily stable strategy, evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation. Among parasitoids, strategies range from living inside the host (''endoparasitism''), allowing it to continue growing before emerging as an adult, to Paralysis, paralysing the host and living outside it (''ectoparasitism''). Hosts can include other parasitoids, resulting in hyperparasitism; in the case of oak galls, up to five levels of parasitism are possible. Some parasitoids Behavior-altering parasite, influence their host's behaviour in ways that favour the propagation of the parasitoid. Parasitoids are found in a variety of Taxon, taxa across the insect superorder Endopterygota, whose compl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uraba Lugens
''Uraba lugens'', the gum-leaf skeletoniser, is a moth of the family Nolidae. It is found in Australia and New Zealand. The larvae are a serious pest of ''Eucalyptus'' species and their close relatives. The wingspan is 25–30 mm. In Australia there are about one or two generations per year.Mansfield S, Kriticos DJ, Potter KJB, Watson MC (2005) Parasitism of gum leaf skeletoniser ( Uraba lugens) in New Zealand. New Zealand Plant Protection 58, 191–196.Berndt LA, Mansfield S, Withers TM (2007) A method for host range testing of a biological control agent for Uraba lugens. New Zealand Plant Protection 60, 286–290. General ''Uraba lugens'' is nicknamed the mad hatterpillar because of its distinctive exoskeletal feature. Every time it sheds the head portion of its exoskeleton, the exoskeleton stays attached to its body. Over time, developing through its life span, the head grows bigger and sheds increasingly larger exoskeleton shells, which build upon each other. ''Uraba ...
