              Study specimens G, H, I and J carefully and answer the following questions.
    (a) (i) Classify specimens G and H according to their feeding habits.             [ 2 marks ]
         (ii) Name one part of crops damaged by each of specimens G and H.     [ 2 marks ]
                                                                          
         (iii) State three ways in which specimen H is economically important.      [ 3 marks ]                                                                                                             

    (b)    State four ways of controlling each of specimens I and J.                    [ 8 marks ]

     

     

Observation

This question was also well attempted by the candidates. In 3(a)(i-ii), majority of the candidates could classify specimens G (Grasshopper) and H (Bean beetle) according to their feeding habits as well as name the parts of crops damaged by specimens G (Grasshopper) and H (Bean beetle) but most of them could not state the ways in which specimen H (Bean beetle) is economically important as required in 3 (a)(iii). However, in 3(b), most of the candidates were able to state the ways of controlling specimens  I (Bird) and J (Rat)
 The expected answers include:
3 (a)(iii)           Ways in which specimen H (Bean beetle) is economically important
                -           Destroys viability of seeds /destroys cotyledon
                -           Reduces market value of crop/quality of crop.
     (ii) Name one part of crops damaged by each of specimens G and H.     [ 2 marks ]

 

                 -           Increases farmer’s cost of production.

                     -          Reduces the quantity of stored produce (seed)
