Background
I obtained B.Sc. in Agriculture (Plant Sciences) from Alemaya University, Ethiopia and worked as a junior and assistant researcher for the Ethiopian Agricultural Research Organization (EARO). I did my M.Sc. in Insect Sciences at Addis Ababa University, Ethiopia. My thesis research was focused on evaluating the insecticidal activity of crude extracts from seeds and leaves of neem tree against African bollworm, Helicoverpa armigera. I then worked for Arba Minch University and Haramaya University as a lecturer where I taught entomology and crop protection courses to undergraduate cohorts. I also obtained M.Sc. in Nematology from Ghent University, Belgium. In my thesis research, I investigated the interaction between root-feeding plant-parasitic nematodes and shoot feeding aphids in a black mustard plant. I obtained Ph.D. in Entomology from the University of Pretoria where I studied the species identity, genetic diversity, natural enemies and host utilization patterns of an invasive pine weevil in South Africa.
I studied eucalypt insect pests and their natural enemies as part of my postdoctoral research. Despite its significant socio-economic role, Eucalyptus production is heavily challenged by non-native and locally adapted insect pests throughout its introduced range. This includes many eucalypt-feeding insects that have been recently introduced in sub-Saharan Africa and pose a serious threat to the sustainability of Eucalyptus forestry in the region. To mitigate this, we developed Eucalyptus Insect Pest Project in Africa (EIPPA). In this project, we investigated the presence, distribution, prevalence, genetic diversity and host utilization patterns of eucalypt insect pests and their natural enemies in sub-Saharan Africa. This was a collaborative project which involved various stakeholders across sub-Saharan Africa. Results from this project will be useful to inform management strategies of eucalypt insect pest in the region.
Current research
My current research focuses on monitoring plant health in sentinel sites such as botanic gardens and arboreta across South Africa. This is a SANBI Biological Invasion Directorate (SANBI BID) funded postdoctoral research project. The project was initiated in 2016 under the frame work of the International Plant Sentinel Network IPSN (www.plantsentinel.org) to improve surveillance and identification of new and emerging pest risks in South Africa. Besides using botanic gardens and arboreta as an early warning system to identify new pest and pathogen threats, the project aims at identifying pre-existing plant health issues. It also works towards building capacity of garden staff in monitoring, detection and management of pests and diseases. It is a collaborative project which involves various stakeholders, including SANBI, FABI, International Plant Sentinel Network (IPSN), horticulturalists and arborists from various botanic gardens and some international scientists in the field of plant health.

News
It has been just over four years since the SANBI-funded postdoctoral project ‘Monitoring plant health in sentinel sites: botanical gardens and arboreta’ started.
In 2017, a collaborative project was developed with the aim of understanding the distribution and genetic diversity of Eucalyptus insect pests and their natural enemies in sub-Saharan Africa.
The 21st Congress of the Entomological Society of Southern Africa (ESSA) with the theme “Innovative Entomology” was held in Umhlanga in the KwaZulu-Natal Province from 8-11 July.
FABI postdoctoral research Fellow Dr Mesfin Gossa recently visited MIRO Forestry Company in Ghana and Sierra Leone, as part of the Eucalyptus Insect Pest Project in Africa (EIPPA). This project is led by Proff Brett Hurley, Bernard Slippers and Dr Gossa, and currently covers over 15 countries in sub-Saharan Africa.
Dr Gerda Fourie, research leader of the Macadamia Protection Programme (MPP) and Dr Mesfin Gossa, Postdoctoral Fellow in the Tree Protection Co-operative Programme (TPCP) attended an Insect Mass-Rearing Workshop held from 23-27 October at Stellenbosch University.
