![]() Aphid Aphids are insects that are parasites on the roots, leaves, and stems of plants. Aphids have a proboscis which contains four sharp stylets which is used to pierce plant tissue and suck out the nutritive juices. Horn-shaped tubes at the rear end of the aphid are called cornicles, and they secrete a waxy substance. Aphids also secrete a sweet substance called honeydew, and some kinds of ants actually hide and keep aphids to "farm" them for this "candy". |
