== Making a tsetse fly trap == '''Materials Requirement''': <br> # One piece of blue material measuring 3m x 1m (Piece A) <br> # One piece of black material measuring 1m x ½m (Piece B1) <br> # One piece of black material measuring 1m x ½m (Piece B2) <br> # One piece of blue material measuring 1m x 1m (Piece C)<br> # One piece of white netting material measuring ¼m x ¼m (Piece D)<br> # Bottle top with a ½ inch pinch hole<br> # A transparent Polythene paper bag to act as a cage for holding tsetse catches.<br> <gallery mode=slideshow> File: Flytrap1.jpg|Piece A File: Flytrap2.jpg|Piece B1 File: Flytrap3.jpg|Piece B2 File: Flytrap4.jpg|Piece C File: Flytrap5.jpg|Piece D File: Flytrap6.jpg|Bottle top </gallery> {{Step | number = 1 | text = Use the blue material (Piece C) as follows: # Label the material A, B, C, D # Fold material diagonally to make a triangle # Fold the triangle into two as shown # Make point X touch CD # Cut on the folded line parallel to CD # Open the new shape # Cut the points B - B1 and D - D1 C # Join B - B1 and D - D1 with staples }} {{Step | number = 2 | text = Use the white netting (Piece D) as follows: # Label the white netting material A, B, C, D and draw diagonal lines joining the points as shown # Cut along the dotted line as shown # Join the line O-B to O-D and staple them together # Cut a small hole on the top of pyramid (at point O) # Fix bottle top to the apex as shown # Join the white netting material (Piece D) to the final product of step 1(Piece C) as shown }} {{Step | number = 3 | text = Use the blue material (Piece A) as follows: # Label the material A,B,C,D. # Fold material into two halves. # Mark the mid point at the top X and the mid point at the bottom Y # From point X measure 1/4m to the left and 1/4m to the right. # Mark the points E and F respectively # From point Y measure 1/2m to the left and 1/2m to the right # Mark the point H and G # Draw a line joining points E-H and F-G # From point F measure 1m and mark the point I # From point E measure 1m and mark the point J # From point J measure 1/2 m downwards and mark this point M # From point I measure 1/2 m downwards and mark this point N # From point M measure 1/4 m towards the right and mark it K # Repeat the same for point N as shown and mark it L # Draw lines joining points J-K and I-L }} {{Step | number = 4 | text = Use the black material (Piece B1) as follows: # Label the material E1,F1,G1,H1 as shown # Fit E1 to E, F1 to F, G1 to G, and H1 to H # Staple along EG to FH }} {{Step | number = 5 | text = Use the black material (Piece B2) as follows: # Mark the material l1, J1 and L1 # From point L1 measure 6 inches and fold the flap using staples. # Repeat the same at point K1 # Fit J1 to J, l1 to l; K1 to K, L1 to L and staple along J-K and l-L # Join final product of step two to final product of step five with staples by fitting A C D to J X }} {{Step | number = 6 | text = The following steps should be followed when setting up the Ngu trap: # Clear the selected trap site of any vegetation # Determine the wind direction so as to site the trap facing the windward side # Erect a back pole to guide in setting up of two-side poles. Firmly peg the back poles.Fasten the trap with pieces of wire to the back poles. Peg in the two side poles and fasten the trap so that the entrance faces the proper direction. Prepare the centre pole by fixing three nails of three inches each with a clearance of two inches each at the top and peg it firmly. Fix the netting on bottle top and support it by the nails at the top of the centre pole. # Fit the polythene cage at the apex of the erected trap and support the cage with strings stretched from thin sticks that are fastened on one of the side poles. # Firmly fix two containers, one for carrying attractant liquid substance (acetone) on the ground next to the back pole and the other for carrying cow urine. The attractant container should be covered with a lid that has a smaller aperture for slowing down the releasing odours as the attractant evaporates. # Fix transparent polythene bag to the top of the trap frame. The polythene bag is used as a cage for holding and suffocating tsetse flies. The sunlight attracts tsetse flies into the cage, which get killed by the heat from the sun. Dead flies in the cage or regularly disposed. For purposes of keeping records, tsetse fly catches are counted and recorded. The tsetse fly catches can also be sorted by age or sex for recording. }} <gallery mode=slideshow> File: Flytrap8.jpg|thumb|Step One- 1, 2, 3, 4, 5, 6, 7, 8 File: Flytrap7.jpg|thumb|Step One-1 File: Flytrap9.jpg|thumb|Step Two-1 File: Flytrap10.jpg|thumb|Step Two-2 File: Flytrap11.jpg|thumb|Step Two-3 File: Flytrap12.jpg|thumb|Step Two-4 File: Flytrap13.jpg|thumb|Step Two-5 File: Flytrap14.jpg|thumb|Step Two-6 File: Flytrap15.jpg|thumb|Step Three File: Flytrap16.jpg|thumb|Step Four File: Flytrap17.jpg|thumb|Step Five-1, 2 File: Flytrap18.jpg|thumb|Step Five-3,4 File: Flytrap19.jpg|thumb|Step Five- 5 </gallery>
