Trichogramma: a Promising Biocontrol Agent
Parasitoids that are able to remove the herbivore from the agroecosystem before larval eclosion are known as egg parasitoids. Mostly they belong to the Hymenopteran order which includes 15 families. Adult of Trichogramma spp. is 0.2-1.00 mm in size with

Effect of photoperiod on parasitization by Trichogramma principium (Hymenoptera: Trichogrammatidae)
The effect of photoperiod on parasitization of the eggs of the Angoumois grain moth, Sitotroga cerealella (Olivier, 1789) by Trichogramma principium Sugonyaev & Sorokina, 1976 was investigated under several photoperiodic regimes of L : D = 3 : 21, 6 : 18,

The genus Trichogramma Westwood, 1833 are important biological control agents of especially Lepidoptera pests in all around the world. These tiny wasps can’t be reliably identified owing to their small size and lack of definable morphological characters.

Parasitism of Cranberry Fruitworm (\u3ci\u3eAcrobasis Vaccinii\u3c/i\u3e; Lepidoptera: Pyralidae) by Endemic or Released \u3ci\u3eTrichogramma Pretiosum\u3c/i\u3e (Hymenoptera: Trichogrammatidae) [PDF]
Two levels of commercially-reared Trichogramma pretiosum were released during the oviposition period of the cranberry fruitworm (Aerobasis vaccinii) in eight Massachusetts (U.S.A.) cranberry bog sites. Release levels of 4.8 X 105 T. pretiosum per ha or 1.

Field Tests of Kairomones to Increase Parasitism of Spruce Budworm (Lepidoptera: Tortricidae) Eggs by \u3ci\u3eTrichogramma\u3c/i\u3e Spp. (Hymenoptera: Trichogrammatidae) [PDF]
Hexane extracts of spruce budworm, Choristoneura fumiferana, moth scales, applied at 0.04 moth-gram equivalents/branch and at 0.06 moth-gram equivalents/tree, failed to increase parasitism rates of Trichogramma spp.
