ERIOSOMATINAE Meaning and
Definition
-
Eriosomatinae is a subfamily of insects belonging to the family Aphididae, commonly known as aphids or plant lice. The term "eriosomatinae" is derived from the Greek words "erion," meaning wool, and "soma," meaning body, which accurately describes the appearance of these insects due to the fluffy or woolly secretions they produce.
Aphids are small, soft-bodied insects that feed on the sap of plants, usually on the underside of leaves or stems. Eriosomatinae, specifically, are known for their unique ability to form galls on plants. Galls are abnormal growths caused by the aphids' saliva, which manipulates the plant's cells and tissue to create a specialized structure that provides shelter and nutrition for the insect.
These woolly aphids are often covered in a waxy or wool-like substance, which serves as a protective layer against predators and harsh environmental conditions. The wax also helps to retain moisture and maintain the aphids' hydration. Eriosomatinae aphids primarily infest various tree species, causing damage to the plants by sucking sap, potentially leading to stunted growth, deformation, or even death of the affected plant.
These insects have complex life cycles, involving asexual and sexual reproduction. They are known to produce winged and non-winged forms throughout the year, allowing them to disperse and colonize new plant hosts. Eriosomatinae aphids are a subject of interest for researchers due to their unique biology, ecological impact, and economic significance in agriculture, as they can cause significant damage to crops.
In conclusion, eriosomatinae refers to a subfamily of aphids, characterized by their ability to produce woolly secretions and induce galls
Etymology of ERIOSOMATINAE
The word "eriosomatinae" is derived from Greek and Latin roots.
The first part of the word, "erio-", comes from the Greek word "erion", which means 'wool' or 'hairy.' This prefix is commonly used in scientific names to refer to organisms that have a woolly or hairy appearance.
The second part of the word, "-soma", is derived from the Greek word "soma", meaning 'body.' In scientific names, "-soma" is often used to refer to a distinct body structure or body part of an organism.
The suffix "-inae" is Latin in origin and is used in taxonomy to indicate a subfamily within a family of organisms.
Therefore, the etymology of "eriosomatinae" indicates that it is a subfamily of insects that have a woolly or hairy body structure.
