TRICHOGRAMMA Meaning and
Definition
-
Trichogramma is a genus of minute wasps that belong to the family Trichogrammatidae within the Hymenoptera order. These tiny wasps, measuring only about 1-2mm in size, are considered parasitoids and are widely known for their remarkable ability to control and suppress populations of agricultural and horticultural pests, particularly various species of moths and butterflies.
The name "trichogramma" originates from the Greek words "trichos" meaning "hair" and "gramma" meaning "that which is written or drawn." This descriptive name is attributed to the densely hairy wings of the adult females.
Trichogramma wasps play a vital role in integrated pest management programs due to their natural biological control capabilities. Their life cycle consists of four distinct stages: egg, larva, pupa, and adult. The female wasps locate the eggs of their host insects, such as moth or butterfly eggs, and lay their own eggs inside them. The trichogramma larvae develop by feeding on the eggs of the host species, eventually killing them. After completing their development, the adult wasps emerge from the host eggs to begin the cycle again.
These minute wasps are commercially reared and released in various agricultural systems as a form of biological control to combat pests. Their use helps reduce the reliance on chemical pesticides, making them an environmentally friendly option for pest management. Trichogramma has proven to be an effective and sustainable solution for controlling numerous pests, making them valuable allies for farmers and gardeners worldwide.
Etymology of TRICHOGRAMMA
The word "trichogramma" comes from the combination of two Greek words: "trikhos" meaning "hair" and "gramma" meaning "letter" or "drawing".
The name was chosen by the Russian entomologist Nikolay Nikolayevich Kuznetsov, who discovered and named the Trichogramma genus in the early 20th century. Kuznetsov named these tiny parasitic wasps Trichogramma due to their delicate and hair-like appearance, which reminded him of fine, delicate lines or letters drawn on paper.
