Abstract
Food short age is a global issue around the world, which is particularly caused by harmful insects
damaging crops. A lot of damage is caused by aphids, leading to respiratory infection and other diseases.
Aphids are parasitic on plants which can be seen throughout the year. We researched on how to decrease
damage caused by aphids. Also, we used allelopathy effects to exterminate aphids. Plants that have
allelopathy effects can exterminate harmful insects. So, we studied which plants have the most
allelopathy effects. Plants that have allelopathy are marigold, mint, Chinese chive and rosemary.

Keywords: allelopathy, food shortage, aphid
