Difference between Aphid and Jassid

Aphid

All Aphids belong to the superfamily Aphidoidea, in that a majority comes under the family Aphididae. These insects are found in various colours, but most of their common names include blackfly and greenfly. These insects are serious agricultural pests that feed on the plant sap. Sometimes a single aphid can also rely on two host plant species to complete its life cycle.

Mutualism

Aphids secrete a sticky and sugary liquid called honeydew. Some ants have a mutualistic relationship with the aphids. The ants use the honeydew secretion as their food source and, in turn, protect the aphids from predators.

Jassid

They belong to the superfamily Membracoidea and the family Cicadellidae. Jassids are minute leafhoppers that feed on plant sap. They act as both agricultural pests and vectors. They can transmit plant viruses, bacteria and phytoplasmas. Sometimes, the pathogen can also multiply inside and infest the pest.

The insect body has hairs that facilitate the distribution of a unique secretion. This secretion usually carries the pheromones, and can also act as a water-repellent layer.

Frequently Asked Questions on Difference between Aphid and Jassid

What is telescopic development?

Some species like the aphids (females) can produce telescopic generations in the absence of males. This means the ability to reproduce without the fertilisation of the ovum. Sometimes, the female nymphs of aphids might be pregnant at the time of live birth. This adaptation is termed telescopic development.

What is a parasitoid?

An organism that lives at the expense of its host is called a parasitoid. Some endoparasites live inside the host and emerge out as adults and eventually result in the death of the host. Whereas there is another category called the ectoparasites, that feed from the outside.
