After transforming the problem in terms of females

Path description

1.Original path- feeding unconstrained, 0 <  harvests < all , 0 < f < max (optimal) (t = 0.5, at b)

2. Original path- feeding unconstrained, 0 <  harvests < all  , 0 < f < max (sub -optimal)

3. Feeding constrained at max, 1, 0 <  harvests < all  , f = max (t = 1.5, at c )

                   4. Unconstrained feeding path reemerges, 0 <  harvests < all  , 0 < f < max (t = 2, at d)

5. Feeding constrained at zero path 2, 0 <  harvests < all  , f = 0 (t = 22, at e)

6. Bang - bang solution  harvests = 0,  harvests = 0, f = max (t  = 30, t = 45 at g )
