Insect - Aphids

Prepared by Frank Zalom, Mark A Bell, April 2008 - UC Davis Aphids are small, soft-bodied insects with long, slender mouth parts that they use to pierce stems, leaves, and other tender plant parts and suck out plant fluids. Identification of species is normally not necessary to control aphids. Aphids often feed in dense groups on leaves or stems. Most aphids do not move rapidly when disturbed. Aphids can have many generations a year. Aphid populations often decrease with summer heat and winter cold.
