Characteristics

Four most economically important aphid species in greenhouse crops - cotton aphid Aphis gossypii, green peach aphid Myzus persicae, potato aphid Macrosiphum euphorbiae and foxglove aphid Aulacorthum solani
Pests are soft bodied and vary in colour, depending on species
Noticeable tubercles and long antennae on head
Large, pronounced mouthparts (stylets)
Pair of abdominal tubes (cornicles) and rectal protrusion (cauda)
Long thin legs with two small claws
Most aphids are wingless – winged offspring produced when host plant quality is low and pest population high
Winged aphids search for new plants to start new colonies
Life cycle
Fast population growth – in spring / summer female aphids are asexual, giving birth to up to 100 live offspring
Ability to telescope generations – mothers give birth to daughters that already contain their grandchildren
Autumn – aphids switch from host plant and reproduce sexually. If conditions allow, aphids can continue to reproduce asexually throughout winter
Hibernate as eggs

Damage caused

Adults/ nymphs suck plant sap – extracting nutrients, reducing plant growth and causing leaf deformation/wilting
Leaves and fruits become sticky – due to excreted honeydew
Unsightly sooty mold – grows on honeydew and impacts photosynthesis
Deformed plant growing tips – caused by toxic substances transmitted in saliva
Can spread over 70 viruses – including CMV
Some ant species have mutualistic relationship with aphids – consuming honeydew while protecting them against predators
