Potential for Mass Rearing of the Egg Parasitoids, <em>Trichogramma chilonis</em> and <em>Tricogramma achaeae</em> (Hymenoptera: Trichogrammatidae) on <em>Corcyra cephalonica</em> Eggs

Effect of Micromite® on the Egg Parasitoids Ceratogramma Etiennei (hymenoptera: Trichogrammatidae) and Quadrastichus Haitiensis (hymenoptera: Eulophidae)

The effect of temperature and humidity on the bionomics of six African egg parasitoids (Hymenoptera: Trichogrammatidae).

The life table statistics of six native Kenyan species/strains of Trichogramma and Trichogrammatoidea were established using a factitious host Corcyra cephalonica, Stainton (Lepidoptera: Pyralidae), at eight different temperatures (10, 15, 20, 25, 28, 30, 32 and 35 degrees C) and two humidity levels (40-50 and 70-80%). The objective was to select insects with superior attributes for augmentativ...

Artificial Diet for Rearing Trichogramma Wasps (hymenoptera: Trichogrammatidae) with Emphasis on Protein Utilization

Trichogramma wasps are tiny hymenopterous egg parasitoids widely used in biological control programs worldwide. The huge quantities of insects necessary for inundative releases are mainly produced on factitious hosts like Ephestia kuehniella (Zeller) (Lepidoptera: Pyralidae), or on silkworms. In order to simplify production, increase its flexibility, and potentially reduce cost, studies on arti...

Effect of pesticides on Colpoclypeus florus (Hymenoptera: Eulophidae) and Trichogramma platneri (Hymenoptera: Trichogrammatidae), parasitoids of leafrollers in Washington.

Pesticides were evaluated for their effect on two parasitoid species, Colpoclypeus flouts and Trichogramma platneri, that are potential biological control agents of leafrollers in apple orchards. Organophosphate and carbamate insecticides were highly toxic to both parasitoids in topical applications, but foliar residues of some products were nontoxic after 7 d. At reduced rates, topically appli...

Egg parasitoids (Hymenoptera: Mymaridae and Trichogrammatidae) of the gall-making leafhopper Scenergates viridis (Hemiptera: Cicadellidae) from Uzbekistan, with taxonomic notes on the Palaearctic species of Aphelinoidea.

A new species of the Aphelinoidea Girault (Hymenoptera: Trichogrammatidae), A. (Aphelinoidea) sariq Triapitsyn & Rakitov sp. n., is described from Uzbekistan. Both sexes were reared from eggs of the only known truly gall-making leafhopper, Scenergates viridis (Vilbaste), laid inside its galls on camelthorn, Alhagi maurorum Medikus; additional females were found dead inside the galls. Aphelinoid...
