The removal of sap creates a lack of vigor in the plant, and aphid saliva is toxic to plants. Aphids frequently transmit plant viruses to their hosts, such as to potatoes, cereals, sugarbeets, and citrus plants. [29] There are two types of virus transmission between plant-aphid interactions: non-circulative transmission and circulative ...

Thus, aphids show very complex and rapidly changing within-year dynamics, with each clone going through several generations during the vegetative season and being made up of many individuals, which can be widely scattered in space. The survival of the eggs and/or overwintering aphids determines the numbers of aphids present the following spring ...
Most milkweed plants grow best in full sun, while common milkweed is happiest in well-draining soil, and swamp milkweed may become stressed and prone to aphids if it’s not grown in moist earth ...
