What is the use of Trichogramma?

What is the use of Trichogramma?

Trichogramma spp. have been used for control of lepidopteran pests for many years. They can be considered the Drosophila of the parasitoid world, as they have been used for inundative releases and much understanding today comes from experiments with these wasps.

What is Trichogramma Chilonis?

Trichogramma chilonis Ishii is being used to control the diamondback moth, Plutella xylostella (Linnaeus), on cole crops in Japan (Miura & Kobayashi, 1993) and in Germany (Wuehrer & Hassan, 1993).

Is Trichogramma a parasite?

Trichogramma wasps are tiny parasites that attack the eggs of over 200 species of moths and caterpillars. They are extremely small – 4 or 5 will fit on the head of a pin. Trichogramma lays its eggs inside the eggs of moths preventing the moth egg from hatching into a caterpillar.

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 card work?

Tricho-cards have a layer of sticky substance which has pasted onto them, eggs of a surrogate host infested with Trichogramma larvae. These eggs then release pests that tackle other pests like leaf roller worms or stem borer worms, which are common threats to standing crops.

Do Trichogramma wasps fly?

Trichogramma wasps are teeny, tiny flying creatures that won’t harm people, pets, or plants. Adult trichogramma wasps feed on pollen and nectar. It’s their young that wreak havoc on harmful worms and catepillars because trichogramma wasps parasitize the eggs of moths, worms, and butterflies (Lepidoptera).

How many eggs are in one card of Trichogramma?

approximately 20,000 eggs
One card contains approximately 20,000 eggs. Trichogramma is used to destroy shoot borer, fruit borer and leaf folder insects of paddy, maize, sugarcane, sunflower, cotton, pluses, fruits and vegetables. It can prevent 80 to 90% loss.

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.

How do you attract Trichogramma wasps?

Make them at home: Adult parasitic wasps eat nectar and pollen. To attract them, plant umbrella-shaped flowers and herbs, such as yarrow, Queen Anne’s lace, zinnias, fennel and dill. These wasps also savor alyssum, cosmos, allium, statice and thyme.

How effective are Trichogramma wasps?

Experiments have shown Trichogramma wasps to be 60% to 95% better at controlling pests such as the bollworm and tobacco budworm than in untreated fields. Trichogrammas often consume up to 98% of a host’s eggs in nature. Females deposit their eggs inside the eggs of host insects.

What plants attract Trichogramma wasps?

Trichogramma wasps

• Achillea filipendulina — Fern-leaf yarrow.
• Achillea millefolium — Common yarrow.
• Allium tanguticum — Lavender globe lily.
• Anethum graveolens — Dill.
• Anthemis tinctoria— Golden marguerite.
• Astrantia major — Masterwort.
• Callirhoe involucrata — Purple poppy mallow.
• Carum carvi — Caraway.

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).

How do you attract Trichogramma?

To attract them, plant umbrella-shaped flowers and herbs, such as yarrow, Queen Anne’s lace, zinnias, fennel and dill. These wasps also savor alyssum, cosmos, allium, statice and thyme.

What is Trichogramma evanescens Westwood?

Trichogramma evanescens Westwood, 1833 is a species of parasitic wasp (Hymenoptera: Trichogrammatidae). Adults are small (barely visible to the naked eye) labeled ‘parasitoids’, which means they deposit their eggs in the eggs of their host species, which is quite varied (can parasitize eggs of several hundred species of moth).

Does Trichogramma evanescens minutum parasitize Amsacta albistriga and Diacrisia obliqua?

Trichogramma evanescens minutum has often been recorded parasitizing the eggs of Amsacta albistriga and Diacrisia obliqua ( Krishnamurti and Usman, 1954 ). A. albistriga eggs are frequently parasitised by T. eyanescens minulum with an effective recovery of 59.4% ( Sundaramurthy et al., 1976; Gunathilagaraj and Babu, 1987 ).

What is a Trichogramma?

Jump to navigation Jump to search. 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.

How do Trichogramma find host eggs?

Trichogramma spp. are also of interest in neuroscience research, having fewer than 10,000 neurons, approaching the theoretical lower limit of the size of an insect brain, yet exhibiting complex behaviors to sustain their lives. To locate host eggs, adult females use chemical and visual signals, such as egg shape and colour.
