	Discovery may help in war against fire ants
		Kathirithamby studies Strepsiptera, a small insect which spends part of its life as an endoparasite or a parasite that develops in the abdomen of its insect host.
		She found that the first-instar infective larva of the Strepsiptera jabs itself between the outer shell and the skin of the host.
		He and Kathirithamby want to study Strepsiptera further to find out whether half the live young produced are male and the other half female, or whether the young are capable of being either male or female, depending on the host.

	Scientific American: Bug-Eyed (Site not responding. Last check: 2007-11-06)
		Parasitic insects known as Strepsiptera are so named for their twisted wings, from the Greek word strepsi, meaning twisted or turned, and ptera, wings.
		Eyelets in Strepsiptera each process a chunk of visual information, as opposed to the single points registered by the facets in compound insect eyes.
		Strepsiptera, however, have fewer and larger lenses, dubbed eyelets, clustered on either side of their head.

	Are strepsipterans related to flies? Exploring long branch attraction (Site not responding. Last check: 2007-11-06)
		Strepsiptera, sometimes known as twisted-wing parasites, is an enigmatic group of insects.
		This raised the possibility that the association between Strepsiptera and Diptera in these trees was an artifact, caused by long-branch attraction (Felsenstein, 1978; Hendy and Penny, 1989).
		The "73" on the Strepsiptera + Aedes + Drosophila branch indicates that in 73 of the simulated matrices, the most parsimonious trees had Strepsiptera with Diptera, even though the model tree on which the data were simulated had Strepsiptera with beetles.

	strepsis (Site not responding. Last check: 2007-11-06)
		Strepsiptera or twisted wing insects are an endoparasitic insect order in which the females, in all but the most basal family, never leave their host.
		Strepsiptera are also frequently mentioned because the systematic position of this insect order remains still unresolved.
		Though it is possible that not all cells were filled, the majority of the fibers appear to be represented, and consequently it is unlikely that a considerable amount of overlap between two neighboring ommatidia exists.

	Paedogenesis (Site not responding. Last check: 2007-11-06)
		In insects, Paedogenesis is a form of neoteny in which the larva l stage reproduces without maturing first.
		It occurs in the females of certain beetle s, Strepsiptera, bagworm s, and gall midge s.
		In the midges, the daughter larvae produced within a mother larva consume the mother and escape; the process may continue for several generations.

	Strepsiptera
		The name Strepsiptera, derived from the Greek "strepsi" meaning turned or twisted and "ptera" meaning wings, refers to the resting position of the male's large hind wings.
		In fact, Strepsiptera and certain parasitic beetles (in the families Meloidae and Rhipiphoridae) are among the very few insects that undergo hypermetamorphosis, an unusual type of holometabolous development in which the larvae change body form as they mature.
		Strepsiptera exhibit hypermetamorphic development: first instars (triungulins) are free-living and highly mobile.

		The strepsiptera only has 100 million nucleotides — the basic structural unit of DNA or RNA — instead of the 175 million found in a Drosophila (fruit or vinegar flies) or the 15 billion or more found in grasshoppers.
		But the strepsiptera has some "unique chunks" attached to the ribosome that are not found in "any other form of life," he added.
		At that size, the female should not be hard to find, but it was 97 years after the male strepsiptera was first described that Kathirinthamby and Johnston identified the female of the species in the fire ant.

		This homeotic hypothesis was given support by molecular phylogenetic analysis of ribosomal DNA (rDNA), that pointed to a sister group relationship between Diptera and Strepsiptera, thereby denying a previously proposed affinity between Strepsiptera and Coleoptera (based on the use of hindwings for flight).
		Until the relationship between Strepsiptera and Diptera is resolved, the plausibly of the homeotic hypothesis is open to question.
		If Strepsiptera are indeed the sister group to Diptera, and evolved by homeosis, they are predicted to possess this intron (at precisely the same insertion site as in flies and moths); absence is predicted if Strepsiptera are allied to Coleoptera or to any other lineage of insects.

	PNAS -- News Archive060203
		Members of a parasitic insect order known as Strepsiptera avoid detection by wrapping themselves inside a piece of hosts' skin, according to new research in PNAS this week.
		However, researchers have been unable to identify Strepsiptera's mechanism to avoid rejection, especially in such a large spectrum of hosts.
		To learn more about the life history of Strepsiptera, Jeyaraney Kathirithamby from University of Oxford and colleagues observed samples of the insect before, during, and after host invasion.

		When she began studying the life cycle of a Pacific species, she noticed that the insects become enclosed in a sheath of thin tissue as they jab their way into the victim.
		DNA tests showed that this bag of skin comes from the host, probably disguising the invader from the host's immune defenses, Kathirithamby and her colleagues report in an upcoming Proceedings of the National Academy of Sciences.
		Understanding how Strepsiptera parasitoids outwit host defenses is particularly exciting, she says, because the order's 500-plus species manage to prey on insects in 34 families.

		One way to demonstrate homology between compound eye facets, and the eyelets of Strepsiptera would be to demonstrate the presence of genes within the strepsitpteran eye, that are typical for compound eyes and have previously been described for Drosophila.
		This project entails the use of a variety of different antibodies and possibly the fabrication of a Strepsiptera specific antibody.
		Depending on the depth of the approach this project could be pursued for a MS or PhD degree.
