Table 5 Cost economic return/benefit of using various oviposition substrates

Treatments	Description	Cost of Diet /preparation / PKR	Cost saving / PKR	Cost economic return
T₁	Cottonseed meal replacing wheat germ meal in the standard diet	741.70	463.80	1.62
T₂	Okra seed meal replacing wheat germ meal in the standard diet	738.40	467.10	1.63
T₃	Seed sprouts of cotton (FH-301 variety)	170.25	1 035.25	7.08
T₄	Seed sprouts of Okra (Sabz Pari variety)	142.50	1 063.00	8.46
T₅	Freshly picked green cotton bolls (FH-301 variety)	86.00	1 119.50	14.02
T₆	Okra fruit (Sabz Pari varieity)	45.00	1 160.50	26.79
T₇	Wheat germ meal based diet (standard diet)/control	1 205.50	-	-

Calculations: The value of US $ 1.00 = 138.44 Pakistan Rupees (during the import period of the chemicals)
The value of (£) 1.00 = 186.14 Pakistan Rupees (during the import period of the chemicals)
Cost saving compared to control = cost in control – cost in treatment
Cost economic return = cost in control/ cost in treatment
