Aphid Control in Your Garden
Hemiptera : Aphididae
Aphids are sap-sucking insects related to Psyllids, Whitefly, Scale Insects and Mealybugs. Aphids are major pests of ornamental and productive plants, and some species (such as Green Peach Aphid) may spread viral diseases between plants.
If the weather is warm and moist, and food is abundant, the conditions are ideal for Aphid numbers to build rapidly. There are about 175 species of Aphids in Australia, and the vast majority of them are introduced species. You are more likely to find Aphids on vegetables and exotic ornamental plants than on native plants.
