Grennbugs are aphids that have become pests of Kentucky bluegrass turf in several Midwestern states, including the Twin Cities. They require control. A greenbug is a light green aphid, about 1/10 inch long. It has a narrow, dark green stripe down the back and black-tipped legs, antennae and cornicles. There are both winged and wingless forms. 

Greenbugs migrate by jet streams to the Northern Great Plains from southern regions each year from April through July. Eggs hatch within the female aphid that then gives birth to live young. A single female can produce 1 to 8 offspring each day for 2 to 3 weeks. Young aphids reach maturity in 6 to 10 days and begin to reproduce without mating. Depending on environmental conditions, from 12 to 20 generations can occur each season. 

Greenbugs are aphids and feed by removing juices from plant tissues with piercing/sucking mouthparts. As they feed greenbugs inject a salivary toxin, which kills plant cells and causes discoloration of the leaf blades. Heavily infested plants turn yellow and may eventually die. Yellow to light-orange or dying turf may be an indication of greenbug infestation. Infestations are often found under drip line of trees. If greenbugs are the problem, close examination of leaf blades should reveal colonies of feeding aphids. Another great way to check for their presence is to run you hand through the grass where damaged turf meets healthy turf. An infested grass blade may support 30 or more aphids. Concentrations of more than 3,000 greenbugs per square foot have been recorded. Mild spring and summer weather facilitates greenbug survival and may result in damaging outbreaks. Infestations generally arise in shaded sites such as under trees or in the shadow of buildings, but may occur in sunny areas as well. 

If large numbers of greenbugs are present and injury is increasing an insecticide application may be warranted. Apply a liquid insecticide to the greenbug infestation, including a 2 to 3 foot border around the damaged area. Thorough coverage is important and may need more than one treatment. Do not irrigate for at least 24 hours after treatment.
