Non-native invasive insects have major impacts on ecosystem function, agricultural production and human health. To make better predictions of where such species may establish and invade, species distribution models (SDMs) are widely used tools to predict potential distributions and invasion extents across new geographical areas. – Read more here
In collaboration with Prof. Susana Clusella-Trullas (Department Botany and Zoology, SU) and Prof. Marshall McCue (St Mary’s University, Texas, USA), John helped co-organize a one-day ‘Stable Isotopes in Invasion Biology’ workshop that was attended by 35 post-graduate students from several institutions across South Africa, hosted by the Centre for Invasion Biology.
ICE 2016 – talks and sessions by John, Maddie Barton, Leigh Boardman (now at UFL) and Minette Karsten, and a strong turnout of socially awkward entomologists!

Prof. John Terblanche hosted an international IAEA workshop at SU in April 2016 on methods and techniques for dormancy management of insects in his Applied Physiological Ecology Lab. Prof. Terblanche is actively involved in two separate IAEA-funded co-ordinated research programs (CRP) investigating novel approaches and methods for increased performance of laboratory reared insects for release in sterile insect programmes.
In a major advance for the understanding of insect invasions, a special issue in the journal Biological Invasions was published in 2016 (Guest editors: postdoctoral fellow Matt Hill, together with Prof. Dave Richardson (C.I.B) , Prof. John Terblanche and Prof. Susana Clusella-Trullas (Dept of Botany and Zoology). A collection of 13 articles from a diverse group of national and international scientists working across different aspects of entomological and biological invasions highlights what makes insect invasions unique and where future research efforts should be focused.
Prof. John Terblanche successfully completed a Canada-Africa Research Exchange Grant with Prof. Phil Matthews at the University of British Columbia which examined how insect’s sense and respond to ambient atmospheric gases (CO2, O2) by means of respiratory chemoreceptors. The exchange culminated in producing an authorative review on the evolution of insect respiratory gas exchange published in Advances in Insect Physiology . Read more here

Matt Hill’s (slightly controversial) paper on Bactrocera invadens and niche overlap among Bactrocera species has just been published. The article is freely available here.
Well done to Elsje Kleynhans for having two papers published this past week – one from her Master’s research on tsetse and environmental variability and the role of phenotypic plasticity and the other from her PhD research on Eldana stalk borers which examines host-plant effects on thermal tolerance.
The APE and CLIME labs did a great weekend away at Landroskop Hut in early December 2013.
Congratulations (and welcome) to Vernon Steyn who joins the lab to work with Kate Mitchell and I on dispersal genetics of invasive fruit flies. Vernon also won double funding from the CIB and NRF for his project.
Congratulations to Dr Matt Hill for securing a prestigious CIB post-doc scholarship to re-focus his research more on invasions and insects.
