Which part of the plant studied by biologist? With the help of aphids?
Answers
Answer:
Aphids can produce several generations per year. Most aphid species reproduce asexually (without mating), with adult females giving birth to live immature aphids called nymphs. Nymphs are always wingless. The nymphs molt, shedding their skin multiple times before becoming adults. Aphids can have simple or complex life histories. Some aphid species use only a single species of host plant to complete their life cycle, whereas other species require two species of host plants. Some aphid species mate and produce eggs, which in some cases are laid on an alternate host, usually a perennial plant species.

Answer:
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 colour. The group includes the fluffy white woolly aphids. A typical life cycle involves flightless females giving living birth to female nymphs—who may also be already pregnant, an adaptation scientists call telescopic development—without the involvement of males. Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly
