Dr. Aruna Manrakhan
Research Entomologist
Programme Coordinator: Fruit Fly

She has 20 years experience of research on fruit flies (Tephritidae) of economic importance, with research projects carried out in Mauritius, Kenya and South Africa on various fruit crops: mango, deciduous fruit and citrus.

Qualifications 
  • Doctor of Philosophy
  • Master of Science (Environmental Ecology)
  • Bachelor of Science (Biology and Environmental Sciences)
Current Research Focus 

Her main research focus is on the biology, behaviour, ecology, monitoring and control of fruit fly pests of citrus.

The Fruit fly projects she is currently leading are on:

  • Use of protein baits for fruit fly control in citrus
  • Determination of non-host status of lemon to fruit flies
  • Determining phytototoxicity of fruit fly baits on fruit previously exposed to copper sprays
  • Efficacy of post harvest cold treatments for control of fruit flies
  • Monitoring systems for fruit flies

She is also leading a new research project on the control of the Asian Citrus Psyllid, Diaphorina citr. The latter has been detected in Tanzania in 2016. In this new prject, we are currently evaluating the efficacy of control methos for the citrus psylla- Trioza erytreae on the ACP. Studies are being carried out in Mauritius where both ACP and the citrus psylla are know to occur.

She is also supervising three PhD projects on the new fruit fly pest- Bactrocera dorsalis in South Africa, one MSc project on the biology and ecology of two closely related fruit fly pest species on citrus- Ceratitis rosa and Ceratitis quilicii and one BSc project on the protein feeding behaviour of two highly polyphagous fruit fly pests of citrus- Ceratitis capitata and Bactrocera dorsalis.
