    Abstract: This study is based on a valuation technique which was applied 
  to <I>Imbrasia belina</I>commonly known as (mopane worms) found in the South 
  East Lowveld of Zimbabwe between December, 2012 and March, 2013. The income 
  value/flow and wealth/stock method was used for the study. Data on tenure regime 
  where the <I>Imbrasia belina</I> were harvested, harvester type (harvester or 
  buyer), age of buyer (years), selling price at local market (R kg<SUP>-1</SUP>), 
  value of mopane worms at the local market (calculated using the formula V = 
  PXQ) where V = Value (Rands), P = Price (R kg<SUP>-1</SUP>) and Q = Quantity 
  of mopane worms harvested (kg)), export selling price (R kg<SUP>-1</SUP>), export 
  value of mopane worms (given by the formula, V<SUB>1</SUB> = P<SUB>1</SUB>XQ<SUB>1</SUB>, 
  where V<SUB>1</SUB> = Export value of mopane worms (Rands), P<SUB>1</SUB> = 
  Price (R kg<SUP>-1</SUP>), Q<SUB>1</SUB> = Quantity of mopane worms harvested 
  (kg)), quantities of mopane worms harvested (kg), quantities of mopane worms 
  bought (kg), quantities of mopane worms exported (kg), quantities of mopane 
  worms consumed at local market (kg), quantities of mopane worms used for personal 
  consumption (kg) and quantities of mopane worms bartered (kg). The data collected 
  in the study area were imputed into the model: V = &#931;<SUP>N </SUP>(P<SUB>ij</SUB>Q<SUB>ij</SUB>) 
  (where, V = Net total discounted value of the (Non Timber Forest Product) NTFP&#146;s 
  from a hectare of forest, P<SUB>ij</SUB> = Price of the jth NTFP&#146;s 
  in the ith period, Q<SUB>ij</SUB> = The quantity or flow of the NTFP in the 
  ith period, N = Number of NTFP&#146;s 
  species) to calculate the local and export values of mopane worms. The existence 
  of the South African export market for mopane worms was significant in (Gonarezhou 
  compared to Chikombdzi and Gonakudzingwa small scale farms compared to Chikombedzi 
  communal, p = 0.000). The average local market price for mopane worms was $7.61 
  kg<SUP>-1</SUP> whilst that for export market was $207.22 kg<SUP>-1</SUP>. The 
  implications of these values is their influence to national governments in determining 
  the level of management and resources that should be allocated to forestry departments 
  towards conservation of non timber forest products like mopane worms.
