Is Trichogramma a parasite?
Scientific name: Trichogramma spp. All members of this family parasitize insect eggs. There are approximately 650 species. Common hosts: Eggs of hundreds of species of insects, especially moths, butterflies, and sawflies.
What is controlled by Trichogramma japonicum?
It is the best biological method of control for rice stem borer, which is the most common pest found in paddies. Trichograma japonicum interferes with the eggs laid by rice stem borer and damage by this pest is reduced to a large extent.
What is the life span of Trichogramma?
Total life span may be 7-75 days depending upon temperature, relative humidity and species of moth parasitized. There may be 30 or more generations per season. Trichogramma is shipped as parasitized moth eggs fixed to cardboard sheets. Each sheet holds about 125,000 Trichogramma.
What is Trichogramma in entomology?
Trichogramma is a genus of minute polyphagous wasps that are endoparasitoids of insect eggs. Trichogramma is one of around 80 genera from the family Trichogrammatidae, with over 200 species worldwide. Trichogramma. Female Trichogramma dendrolimi on egg of armyworm (Noctuidae)
Why Trichogramma spp are considered important biological control agents?
The major advantage of Trichogramma species as biological control agents is their extremely small size; adult egg-parasitoids measure only 0.3 mm in length, making them virtually invisible to the casual observer (Fig. 9).
What type of pest control is Trichogramma?
T-gramma (Trichogramma) are tiny, parasitic wasps (less than 0.5mm) that are natural antagonists of the clothes/food moths. They feel most comfortable at temperatures above 20°C and are then most effective. T-gramma can be used all year round.
How does Trichogramma work?
Trichogramma lays its eggs inside the eggs of moths preventing the moth egg from hatching into a caterpillar. This prevents the damage caused by the feeding caterpillars, and also breaks the life cycle of the pest, effectively preventing the pest from reproducing.
Why do Trichogramma spp are considered important biological control agents?
The major advantage of Trichogramma species as biological control agents is their extremely small size; adult egg-parasitoids measure only 0.3 mm in length, making them virtually invisible to the casual observer (Fig. 9). Trichogramma spp.
Can Trichogramma wasps fly?
Because of the exceptional well developed sense of smell the tricogramma finds the eggs of food moths and parasites these. The ichneumon wasp cannot fly and is therefore only effective in a limited area (1 tricho card per shelf).
What type of insect is Trichogramma?
wasps
Trichogramma spp. are small wasps that are endoparasites of lepidopteran eggs. The major advantage of Trichogramma species as biological control agents is their extremely small size; adult egg-parasitoids measure only 0.3 mm in length, making them virtually invisible to the casual observer (Fig.
What is the importance of Trichogramma?
The importance of Trichogramma Trichogramma as biocontrol agent The Trichogramma pasasitoids and other egg parasites are desirable biological control agents due to the following reasons: (1) they attack and kill a variety of lepidopterous eggs before they can damage the crop; (2) they are relatively specific to the …
How do you release Trichogramma?
Place Trichogramma card pieces or loose eggs into the container, add strip of honey paper (optional), and close. Hold in a warm place, 70 – 80 degree F, 60% RH, for 1 – 4 days until they are hatching. The males emerge first and wait for the females to emerge later in the day.
Which Trichogramma eat clothes moths?
by the thousands, tiny parasitic Trichogramma wasps, each less than a millimeter long, home in on moth eggs, into which they plant their own eggs. Wasp larvae consume the moth eggs before a moth larva develops.
