Explanation
a (i) Effects of specimen P (Aphid) on crops -
- Causes stunted growth
- Reduces the yield of crops
- Transmits diseases to crops/vector of diseases
- It produces Honey dew which covers the leaves of crops and reduces photosynthesis
- Piercing through outer tissues and sucking nutritional sap
(ii) Ways of controlling specimen P (Aphid) -
- Use of lady bird beetle
- Spray with insecticides
- Uproot and burn infected plants
- Hand picking of adult aphid and nymphs and destroying them
(b) (i) Benefits of including the crop from which specimen Q (cowpea seeds) were obtained in a mixed cropping system
- Covers the soil thereby protecting it against erosion
- Adds nitrogen to the soil
- Helps to smother weeds
- Serves as source of fodder after harvesting
(ii) Major storage pest of specimen Q(Cowpea seeds); Bean beetle
(c) Uses of specimen R (Coconut fruit);
- Eaten as food by humans
- Fed to farm animals
- Processed to obtain vegetable oil/coconut oil
- Source of fibre should be used as fuel/in making foot mat and brush
- Source of coconut water used to produce fruit juice
- Shell is used as abrasive
- Coconut water is used as medicine
- Used for crafts/decoration
- Raw material for industries e.g. cosmetic industry
(d) Botanical names of the crops from which specimens Q(Cowpea seeds) and R (Coconut fruit) were obtained;
- Specimen Q: Vigna unguiculata
- Specimen R: Cocos nucifera
