The Aphididae are a very large insect family in the aphid superfamily (Aphidoidea), of the order Hemiptera. These insects suck the sap from plant leaves. Several thousand species are placed in this family, many of which are considered plant/crop pests. They are the family of insects containing most plant virus vectors (around 200 known) with ...
Aphids are small sap -sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, [ a ] although individuals within a species can vary widely in color. The group includes the fluffy white woolly aphids.
A. nerii. Binomial name. Aphis nerii. Fonscolombe, 1841 [1] Synonyms. Aphis lutescens Monell, 1879. Aphis nerii is an aphid of the family Aphididae. [2] Its common names include oleander aphid, milkweed aphid, [3] sweet pepper aphid, [4] and nerium aphid.
Honeydew is a sugar -rich sticky liquid, secreted by aphids, some scale insects, and many other true bugs and some other insects as they feed on plant sap. When their mouthpart penetrates the phloem, the sugary, high-pressure liquid is forced out of the anus of the insects, allowing them to rapidly process the large volume of sap required to ...
In aphids, the presence of a particular species of γ-3 Pseudomonadota makes the aphid relatively immune to their parasitoid wasps by killing many of the eggs. As the parasitoid's survival depends on its ability to evade the host's immune response, some parasitoid wasps have developed the counterstrategy of laying more eggs in aphids that have ...
Macrosiphum rosae, the rose aphid, is a species of sap-sucking aphids in the subfamily Aphidinae. [1][2] They have a world-wide distribution and infest rosebushes as the main host in spring and early summer, congregating on the tips of shoots and around new buds. Later in the summer, winged forms move to other rose bushes, or to a limited ...
Aphis. Aphis is a genus of insects in the family Aphididae containing at least 600 species of aphids. [1] It includes many notorious agricultural pests, such as the soybean aphid Aphis glycines. Many species of Aphis, such as A. coreopsidis and A. fabae, are myrmecophiles, forming close associations with ants.
Insects such as aphids are considered crop pests, and therefore the aphid-eating larvae of some hoverflies are economically and ecologically important. The larvae are potential agents for use in biological control; while the adults are pollinators. About 6,000 species in 200 genera have been described.
