Preliminary work to develop experimental procedures showed that: a few C. brevitarsis  could survive in buried dung; dung beetles and C. brevitarsis  coming to dung were unaffected by a background of shade-cloth used experimentally to prevent dung burial; the most abundant dung beetle, Onthophagus gazella  L. and C. brevitarsis oviposition occurred concurrently in the first 2 d after dung deposition, and the potential for interaction between dung beetles and C. brevitarsis was greatest in open pasture adjacent to trees where cattle congregate at night. Laboratory experiments on dung burial showed that C. brevitarsis  numbers decreased as numbers of dung beetles increased or as the dry weight of dung decreased due to burial. This was seldom reflected in the field where, although significant burial occurred experimentally in 9 of 20 trials over 3 years, a significant decline in C. brevitarsis  numbers attributable to burial only occurred once. C. brevitarsis  numbers in the field were lower in unburied dung in 70% of trials. Differences were significant twice and were considered the result of dung disturbance. In the laboratory, decreasing numbers of C. brevitarsis  were related to three characteristics of disturbance: the flattening, spreading and reduction in wet weight of the dung. Evidence of C. brevitarsis  activity throughout coastal NSW suggests that, while C. brevitarsis  numbers may be modified by dung beetles, the interaction is insufficient to prevent their increase, spread and ability to transmit viruses to livestock.10abovine dung10aburial10aDisturbance10aOnthophagus gazella10aOnthophagus granulatus1 aBishop, Alan, L.1 aMcKenzie, Harry, J.1 aSpohr, Lorraine, J.1 aBarchia, Idris, M.  uhttps://scarabnet.myspecies.info/interactions-between-dung-beetles-coleoptera-scarabaeidae-and-arbovirus-vector-culicoides-brevitarsi00585nas a2200109   4500008004100000245018900041210006900230300001200299490000700311100001900318856013800337       2003                        eng d00aDistribution of two endemic and flightless tropical dung beetles, Amphistomus pectoralis  Matthews and Temnoplectron involucre Matthews (Coleoptera: Scarabaeinae), at a rainforest edge0 aDistribution of two endemic and flightless tropical dung beetles  a212-2130 v421 aRortais, Agnes  uhttps://scarabnet.myspecies.info/distribution-two-endemic-and-flightless-tropical-dung-beetles-amphistomus-pectoralis-matthews-and-te03151nas a2200205   4500008004100000245011500041210006900156300000900225490000700234520242000241653001902661653002202680653001602702653002002718653001702738653001302755100002702768700001702795856013302812       2007                        eng d00aSummer activity patterns of nocturnal Scarabaeoidea (Coleoptera) of the southern tablelands of New South Wales0 aSummer activity patterns of nocturnal Scarabaeoidea Coleoptera o  a7-160 v463 aAustralia has a rich diversity of Scarabaeoidea; however, little is known about the majority of them. Because adults of Anoplognathus, Automolius, Heteronychus, Heteronyx and Liparetrus in particular are reliant upon eucalypts, a number of bluegum plantation companies supported the commencement of research into the biology and ecology of scarabs of economic significance to them. Consequently, it was decided that the occurrences of species endemic to this area would be studied and it was assumed that information on the nocturnal species in the aforementioned genera would be obtained. From late November 2003 until late February 2004, the abundances of Scarabaeoidea caught in two light traps that partition insects caught on a given night into seven time periods each of 1.75 h duration were recorded. A total of 48 263 scarabs representing 21 genera were caught. Within the 14 species caught most often, six types of summer activity pattern were apparent: late spring to early summer (Austral- obolbus gayndahensis), early to mid-summer (Scitala sericans), mid-summer only (Sericesthis ignota), mid- to late summer (Acrossidius tasmaniae, Aphodius lividus, Heteronyx chlorotica, Het. praecox and Antitrogus morbillosus), late summer only (Ataenius picinus) and all summer (Anoplognathus pallidicollis, Phyllotocus macleayi, Sericesthis geminata, Ser. micans and Ser. nigrolineata). Abundances of nine species peaked between 21:30 and 23:15 h (Aph. lividus, Phy. macleayi, Het. chlorotica, Sci. sericans, Ser. geminata, Ser. micans, Ser. nigrolineata and possi- bly also Ant. morbillosus), three were most abundant between 19:45 and 21:30 h (Ano. pallidicollis, Ser. ignota and possibly also Ata. picinus), another two were most abundant from 19:45 to 23:15 h (Acr. tasmaniae and Het. praecox) and Aus. gayndahensis was most abundant between 23:15 and 01:00 h. Of course, it is not just a knowledge of the identity of the species and the timing of their occurrence that are important when making insect management decisions, but also the size of popu- lation needed to inflict economically significant loss. It is now beholden upon bluegum plantation companies to support further research to determine the relationships between light trap catches of eucalypt-feeding scarabs, tree age and/or size and level of defoliation in order to improve their confidence in this method of monitoring over ground surveys. 10aBolboceratidae10aChristmas beetles10acockchafers10apasture scarabs10aScarabaeidae10aTrogidae1 aSteinbauer, Martin, J.1 aWeir, T., A.  uhttps://scarabnet.myspecies.info/summer-activity-patterns-nocturnal-scarabaeoidea-coleoptera-southern-tablelands-new-south-wales
