    Symptoms: Potato aphid infestations are sporadic in occurrence and rarely severe enough to kill is caused by both nymphs and adults sucking sap from foliage, especially from the terminal growth. New growth may become stunted and curled. Aphids are small sap-sucking insects and members of the superfamily names include greenfly and blackfly, although individuals within a species can vary widely in colour. The group includes the fluffy white woolly aphids.A typical life cycle involves flightless females giving living birth to female nymphs—whom may also be already pregnant, an Class: Insecta.

    Aphids have a number of natural enemies, and these insects are much better at controlling aphids than any other method available to gardeners. Pampering and nurturing their natural enemies is an excellent method of organic aphid control. Introduce beneficial bugs, like lacewings and ladybugs, to your garden as a natural way to kill aphids. Potato Aphid infestations rarely result in plant kill and tend to be sporadic in occurrence. Using their stylets, aphids feed from various parts of the plant (stems, growing tips, blossoms and veins). If thresholds are high enough, blossoms are dropped resulting in yield loss, and new growth becomes stunted or curled.

    to knock the Aphids off of your plants. • Plant “trap crops” like calendula, nasturtiums, and dill. Aphids like to eat these plants even more than your vegetables, so you can attract aphids away from your other plants! • Try planting Pollen & Nectar Producing Plants (see list, page 48) to attract good bugs that will eat the Aphids. Wingless potato aphid adults are to mm in length, which makes them the largest of the potato-colonizing aphids in Atlantic Canada. The body is elongate, wedge-shaped, yellowish-green to pink and darker along the middle of the back.

Four species of aphid (greenfly) occur commonly on the leaves of potato: the peach—potato aphid (Myzus persicae (Sulzer)), the buckthorn—potato aphid (Aphis nasturtii Kaltenbach), the potato aphid (Macrosiphum euphorbiae (Thomas)) and the glasshouse and potato aphid (Aulacorthum solani (Kaltenbach)); a fifth, the violet aphid (Myzus ornatus Laing).

The Peach-Potato aphid Myzus persicae has traditionally been considered as the most important aphid vector of potato viruses. However, in Scotland, Peach-Potato aphids generally fly later and in far lower numbers than in warmer countries and their relative scarcity generally makes this species less of a concern to potato growers.
