Honours update – Sandie

I have completed two of the three proposed experiments for my honours project so far. I have completed the secondary seed dispersal experiment, looking at how tunneller dung beetle species, Onthophagous binodis, and dweller dung beetle species, Aphodius fimetarius, contribute to the ecosystem service of secondary seed dispersal in Australia by using beads as surrogates for seeds, and observing and recording if they take the bead seed mimics underground when creating brood balls, or if they move the beads around in general through their manipulation of the cattle dung, and the depths at which they take these broods. I have counted all the beads in the brood balls and am currently putting the data together in spreadsheets for analysis. I have also completed the roller experiments proposed using the arena. I used species Sisyphus spinipes and Sisyphus rubrus for these experiments and conducted a number of pilot studies looking at how far roller species take their brood balls, if they have preferential burial sites, and if they would take seeds within the dung (bead mimics) in their broods. The data from this experiment is ready for further analysis. At present and I am conducting the third proposed experiment for my honours project, which involves looking at the difference in gas emissions in frozen cattle dung vs. unfrozen cattle dung. For this experiment I am using the Gasmet machine in the zoology glasshouse for a period of time yet to be fully determined. Furthermore, I am in the process of organising the data collected from my experiments so I can analysis it statistically and make a series of graphs, and am also in the process of reading papers and writing my thesis.

I am now seven months into my MSc., investigating beetle diversity on Acacia host-plants along an environmental gradient. Since the last issue of Myrmecia I have been busy in the lab sorting through the Coleoptera specimens, which were collected over six seasons. Coleoptera from seasons 1-3 will be sorted into morphospecies by the end of October. Voucher specimens are being identified to family level, photographed and databased using Biota (biodiversity database manager). Photographs are being catalogued separately using Adobe Lightroom (see Figure 2). Preliminary results for the first two seasons (spring & summer) are showing that temperate sites host the highest beetle diversity, while the chrysomelids (leaf beetles) are currently the most diverse beetle taxa across the gradient.

I started my PhD investigating the interactions between two parasitoid wasps (Encarsia formosa and Eretmocerus warrae) and a predatory Hemiptera (Nesidiocoris tenuis) as natural enemies of greenhouse whitefly (Trialeurodes vaporariorum). Greenhouse grown tomatoes are an important industry in the New England area. The use of biological control can minimise or eliminate the need for chemical control of these pests. I will commence confirmation of identification of the parasitoid and whitefly species in the greenhouse and then undertake laboratory experiments to examine the feeding and oviposition preferences, the extent of multiparasitism, the level of competition and the outcome of interactions between these natural enemies. Greenhouse tests will then be conducted to determine the most effective combination for control of T. vaporariorum.

My temperature controlled chambers have been completed and are ready for the effects of temperature on dung beetle experiment. They work very well and I have high hopes for them. Currently I’m just waiting for beetle season to commence before beginning the experiment. In meantime I have been sorting through samples from my altitudinal gradient survey. As expected there are few beetles active in the winter months but there have been one or two surprise finds. It’s almost time to do another run to collect samples from my wonderful volunteers and drop off some more supplies. The endnote dung beetle library has been updated again and now has close to 1900 papers.
