Abstract

Morphology, biology and host stages preference of Ecarsia formosa Gahan (Hymenoptera: Aphelinidae) and characteristics of egg, three larval instars, pupa and adult were studied in Isfahan. The average of growth period of parasitoid from egg to adult in 1st to 4th nymphal instars, prepupa and pupa of its host, the greenhouse whitefly, Trialeurodes vaporariorum Westwood (Homoptera: Aleyrodiae) was determined 20.3 ± 0.82, 17.4 ± 0.54, 16.1 ± 0.4, 15.1 ± 0.51, 14.8 ± 0.41 and 14.3 ± 0.52 days respectively at 24 ± 1°C, RH 65 ± 5% and 16.8 (L:D). The 3rd and 4th nymphal instars were the best stages for parasitism. Host feeding of parasitoid was further on 2nd nymphal instar and pupa. The average of growth period in 4th nymphal instar of host for egg, 1st, 2nd 3rd larval instars together and pupa was 3.3 ± 0.25, 1.8 ± 0.77, 3.2 ± 0.26 and 7.9 ± 0.39 days respectively. The full developed larva, primitive pupa, pupa with white, white - red and black-red eyes and adult were appeared 8.15 ± 0.42,9.15 ± 0.29, 10.35 ± 0.33, 12.4 ± 0.39, 14.55 ± 0.33 and 16.15 ± 0.72 days after ovipositing, respectively. This parasitoid is thelytokous parthenogenetic insect. Males were rarely observed. The size of parasitoid (width of head capsule) was positively corre1eted with the size of its host. The most number of parasitized nymphs was limited to middle regions of host plant, lantana camera.
