Green Peach Aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae)
Green peach aphid is found throughout the world, including both tropics and temperate latitudes. It is considered to be a pest nearly everywhere, often due to its ability to transmit plant viruses. In addition to attacking plants in the field, green peach aphid readily infests vegetables and ornamental plants grown in greenhouses. This allows high levels of survival in areas with inclement weather, and favors ready transport on plant material. When young plants are infested in the greenhouse and then transplanted into the field, fields will not only be inoculated with aphids but insecticide resistance may be introduced. These aphids are also reported to be transported long distances by wind and storms.
The life cycle varies considerably, depending on the presence of cold winters. Development can be rapid, often 10–12 days for a complete generation, and with over 20 annual generations reported in mild climates. Where suitable host plants cannot persist, the aphid...
