Artificial host egg for rearing trichogramma. by Jarrett D Hoffman | 1 Jan Unknown Binding Currently unavailable. The wasp, Trichogramma Minutum Riley, as an egg parasite of the moth Cactoblastis cactorum (Berg) (University of Hawaii) by Alden Goodreads Book reviews & recommendations. In Vitro Rearing of Egg Parasitoids /_ In book: Egg Parasitoids in Agroecosystems with Studies on using Trichogramma spp. reared on artificial host egg to. 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 mm in length, making them virtually invisible to the casual observer (Fig. 9). Trichogramma spp. are probably best suited for preventive treatment on . However, as the artificial host eggs can only be used for mass rearing of T. dendrolimi and T. chilonis, and also because the costs of artificial host egg production for Trichogramma were higher than costs of A. pernyi egg production, in northeast Cited by:

Artificial host eggs made of a polyethylene film (15 µm thick) in the form of hemispheri-cal cupules were filled with artificial medium (about 5 µl) used as the diet for larval develop-ment. Each rearing device contained 30 cupules arranged as a 6 x 5 matrix. The experiments.   Rearing Of Trichogramma spp. Several steps used for rearing: 1. Collection of Trichogramma from field as founder population, propagation and conservation 2. Selection of host eggs and their storage 3. Exposure of Trichogramma to host eggs on large quantity 4. Mass production for Augmentation releases 6. Host used for Trichogramma rearing 1. Mass production technique of Tricho- gramma spp., in vitro rearing of Trichogramma spp. on artificial host eggs as well as the quality control guidelines for . For example, for Trichogramma that parasitizes moth eggs, the adult wasps use odors from moth scales accidentally knocked off while the moth was laying the eggs. Once the female has found a host egg, she probes it with her ovipositor to determine a few things. She decides that it is an acceptable host only if the host egg is fresh, healthy, and.

  Abstract. Among the egg parasitoids families of Hymenoptera, Trichogrammatidae is by far the most produced in large scale worldwide. Species of Trichogrammatidae are used in more than 30 countries for the biocontrol of over 20 host-pests in crops such as corn, cotton, sugarcane, fruit trees, vegetables, forests, among by:   Grenier S () Rearing of Trichogramma and other egg parasitoids on artificial diets.
