Brown citrus aphid

Brown citrus aphid

Aphis citricidus

A species of Aphis

The brown citrus aphid is a sap-feeding insect often found in temperate regions, where it forms dense colonies on the young shoots and undersides of leaves of specific host plants. With a complex life cycle, this organism can reproduce both sexually and asexually, depending on environmental conditions. During its asexual phase, females give birth to live offspring, a trait relatively rare among insects. Its presence can influence the growth of sooty mold due to the production of honeydew, a sugary by-product excreted after feeding on plant sap.

Adult brown citrus aphid prefer the tender shoots and underside of leaves where they continue to feed and reproduce.

Agricultural Pests

When brown citrus aphid infests citrus plants in large numbers, they severely weaken the plants by sucking sap from leaves and stems. This impairs photosynthesis, stunts growth, and can lead to leaf curl, yellowing, and reduction in yields. Infested plants may also become coated in honeydew, encouraging sooty mold. Mild infestations cause less drastic symptoms but can still affect plant vigor and fruit quality.
