Aphis nerii

The oleander aphid is widespread in regions with tropical and Mediterranean climates.^[6][7] In Poland, oleander aphid has only been reported from a glasshouse.^[8] Small populations of oleander aphid are present in gardens in London, England.^[9]

Female aphids lay live young (nymphs), a process known as viviparity.^[6] Female aphids reproduce by parthenogenesis. Males have never been observed in the wild but have been produced under laboratory conditions.^[10] Females may be wingless or winged (alate), the production of the alate form occurs at a higher rate in regions where the aphid must migrate to temporary hosts each year.^[11]

Oleander aphid has a wide range of hosts, but mainly feeds on plants in the dogbane family, including milkweeds, oleander and periwinkle.^[9] It is occasionally recorded feeding on plants in the bindweed family, daisy family and spurge family as well as rarely being recorded on Citrus.^[12]

Oleander aphid can act as a vector of viruses in the genus Potyvirus and Cucumovirus. The following viruses are known to be vectored by oleander aphid:

• Araujia mosaic virus^[13]
• Bean yellow mosaic virus^[14]
• Bittergourd mosaic virus^[15]
• Citrus tristeza virus^[16]
• Cucumber mosaic virus^[17]
• Lentil mosaic virus^[18]
• Papaya ringspot virus^[19]
• Tobacco etch virus^[20]
• Watermelon mosaic virus^[21]
• Zucchini yellow mosaic virus^[22]

• A European paper wasp preying on Milkweed aphids which are on narrow leaf milkweed. Most scenes are repeated at one-fourth speed
• Milkweed aphids on narrow-leaf milkweed eliminating honeydew. Unlike some aphids, these kick the drop away with their leg
• A milkweed aphid moulting on narrow-leaf milkweed. Shown at ten times speed
• A milkweed aphid on narrow-leaf milkweed is attacked by a hoverfly larvae. It thrashs and release pheromones and sticky wax from its cornicles. Nearby aphids flee. Video played at 4X speed
• A milkweed aphid pushes the sticky wax drop from its cornicle against an attacking parasitic wasp, extruding another drop. Two scenes at one-tenth speed. A different aphid has captured a wasp
• Winged adult (alate) aphids. Some scenes repeated at one-twentieth speed. Recorded at 60 fps
• Hoverfly larva on narrow-leaf milkweed with milkweed aphids, ladybird eggs, and larva. After first minute, shown at four times speed. Larva recorded in early morning prior to sunrise
