(Skelley & hoy 2004). as new adult parasitoids emerge, they can be collected and field-released to establish the parasitoid in new areas or to augment existing parasitoid popula- tions. however, sometimes it may not be possible to immediately release adults, in which case it would be advantageous to know how best to store them until release. the objectives of experiments presented here were to investigate survival of adult T. radiata stored under different food, light and tempera- ture conditions. adults were obtained from a uS- da-arS colony of the parasitoid established dur- ing 2011. this colony is maintained using psyllids reared on alemow, Citrus macrophylla Wester, following the basic procedures presented by Skel- ley & hoy (2004). four storage experiments were conducted. in each experiment, adult T. radiata (< 24 h old) were aspirated into clear-styrene, 9-dram plastic vials (26 mm diam × 67 mm tall) with snap-on lids (#8909, bioQuip products, gardena, california) using a bioQuip aspirator (#1135a) operated manu
