Testes injured in fly (6)

Ross

I believe the answer is:

tsetse

'fly' is the definition.
(tsetse is a kind of fly)

'testes injured' is the wordplay.
'injured' indicates anagramming the letters.
'testes' with letters rearranged gives 'TSETSE'.

'in' acts as a link.

(Other definitions for tsetse that I've seen before include "carrier of disease" , "flies" , "source of sleeping sickness" , "Bloodsucking African fly" , "Disease-carrying fly" .)

I've seen this clue in The Independent.
