Distribution
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]
Lifecycle
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]
