Aphid, member of the order Homoptera, is probably the most notorious pests in the world.   An aphid feeds on plants by inserting its proboscis, stylet or straw like mouthpart into phloem or inner cells of plant. Upon insertion the aphid draws the plant’s juice or sap. This feeding activity will normally cause leaf and stem deformities and it can aid the transmission of various plants, disease both bacterial and viral, all which can affect the plant’s appearance and value.
