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.
Hemiptera (/ hɛˈmɪptərə /; from Ancient Greek hemipterus 'half-winged') is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from 1 mm (0.04 in) to around 15 cm (6 in), and share a ...
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.
Syrphinae. Hoverflies, also called flower flies or syrphids, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs ...
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 ...
Psocodea contains around 11,000 species, divided among four suborders and more than 70 families. [1][2][8] They range in size from 1–10 millimetres (0.04–0.4 in) in length. The species known as booklice received their common name because they are commonly found amongst old books —they feed upon the paste used in binding.
Female aphids reproduce by parthenogenesis, males have never been observed in the wild but have been produced under laboratory conditions. [10] Females may be wingless or winged ( alate ), the production of the alate form occurs a higher rate in those regions where it is necessary for oleander aphid to migrate each year on to temporary hosts.
