Contributions to our knowledge of the Hemipterous genera Dieuches Dohrn (Lygaeidae : Rhyparochrominae), Rhypodes Stål (Lygaeidae : Orsillinae) and Chinamiris Woodward (Miridae : Mirinae) with supporting papers on other Rhyarochrominae, Orsillinae and Miridae, other Hemiptera, and insects in other orders : application for the degree of Doctor of Science from Massey University, Palmerston North, New Zealand

When the applicant was awarded a Sir Walter Mulholland fellowship in 1966, the opportunity arose for a post-doctoral fellowship at the University of British Columbia, Vancouver, Canada, where Professor G. G. E. Scudder was , and still is, working on the lygaeid subfamily Rhyrparochrominae of the World. Here was the chance to work on a large, difficult genus containing species from many different parts of the world, and thus make a major contribution in this area. The choice was between Dieuches Dohrn and Pachybrachius Hahr. because no other genus in the Rhyparochrominae contains anything like the number of species contained by thesetwo genera. The complex genus Dieuches was selected. On account of his teaching and other duties, Professor Scudder's available time for research was not unlimited, and as he put it, it would be a great help to him to have that genus thoroughly revised. My training has been on Hemiptera, family Lygaeidae,with an M.Agr.Sc. thesis (Massey 1958) on Nysiushuttoni (White) - subfamily Orsillinae, and a Ph.D.thesis (University of London, 1962) on some Rhyparochrominae with special reference to their feeding habits.
Systematics, bionomics and distribution of the plant bug Nysius huttoni White (Heteroptera : Lygaeidae) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in the University of New Zealand
(Massey University, 1958) Eyles, Alan Charles
Nysius huttoni White, endemic to new Zealand is a member of an almost cosmopolitan genus which shows remarkable adaption throughout the world. As it is the only Nysius species so far recorded from this country, some attention to it is surely due, if for no other reason. There are, however, other valid reasons which prompted this study, ands these are as follows. Relatively little work has been carried out on N. huttoni, there being only one study (by Gurr, 1957) specifically on this insect; the immature stages have not been described; no illustrations of any of the instars either nymphal or imaginal have been published, except for one photomicrograph by Blair and Morrison (1949) of a balsam-mounted image, but it is so distorted as to be unrecognisable; the systematics of the insect has not been fully studied, for Usinger (1945) states that two species may be represented; the number of broods per year is not known, but Myers (1926) states that there is probably more than one. An attempt has been made to elucidate the subject along these lines. Further, the insect occurs in large numbers and is easily caught, which two factors contribute much to the suitability of the insect for study material. Thus N. huttoni presents ample for a general study on the bionomics of an animal [From Introduction]
