What type of parasitoid is Trichogramma?
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.
