AphidsOne of the most common and widespread insect pests is the aphid.  We can find these on many plant hosts during most of the growing season.  They feed by sucking plant juices from foliages or twigs.  Once detected, they are very easy to suppress. Sometimes they can be swept off of plants with a stream of water, though some will return. Damage to plants appears as reduced vigor and as distortion of foliar growth.
