Whitefly, Aphids, Sciarids
Whitefly and aphids are important pests of greenhouses, gardens and house plants. They suck the sap from leaves and stems, often transmitting plant viruses in the process. Their honeydew secretions can also lead to sooty mould growth on leaves. Sciarids or fungus gnats are primarily nuisance insects although in high infestations larval feeding on roots can stunt plant growth.
