COMPARATIVE DEVELOPMENT AND BIOCHEMICAL ANALYSES OF TRICHOGRAMMA (HYMENOPTERA, TRICHOGRAMMATIDAE) GROWN IN ARTIFICIAL MEDIA WITH HEMOLYMPH OR DEVOID OF INSECT COMPONENTS

Performances of different artificial media for the oophagous parasitoi d Trichogramma dendrolimi Matsumura (Hymenoptera: Trichogrammatidae), some of them devoid of insect components, were evaluated by comparing biological parameters and biochemical (amino acid) analyses, Egg layin g and development up to adult took place even in artificial media devo id of insect additive, The differences in parasitism rate and composit ion of pupae obtained from artificial media vs. from control eggs of E phestia kuehniella Zeller (Lepidoptera: Pyralidae), can be explained b y the medium composition, Modifications of the composition of the basi c medium led to significant improvements of the results. Parasitism ra te was increased and composition in amino acid of Trichogramma develop ed in artificial media was improved by adding protein hydrolysate.
