This research studied the effect of feeding adult wasps from different pollen diets on the longevity, fecundity rate, and survival rate of H. hebetor. This experiment was conducted in seven pollen diets with four replications. The diets included control, rapeseed, apple, peach, almond, date, and honeybee pollen. Also, honey and vitamin C were used in all diets. The experiments were performed in controlled conditions. According to the results, pollen diets did not significantly affect longevity. Still, fecundity showed a significant increase in honeybee, rapeseed, and date pollen diets compared to the control. Honeybee and rapeseed pollen diets have the highest increase in fecundity and were in the same group. According to the obtained results of analysis of variance, values of the intrinsic rate of increase (rm), grass reproduction rate (GRR), net reproduction rate (R0), and doubling time (DT) in different pollen diets showed a significant difference. The intrinsic rate of increase of H. hebetor was significantly higher in the almonds pollen diet (0.065 ± 0.003 d-1) compared to others. The maximum value of grass reproduction rate (GRR) and net reproduction rate (R0) related to the date pollen diet (3.38±0.32 and 2.61±0.39 female/female). The minimum population doubling time (DT) was related to the almonds pollen diet (10.58 ±0.6 d). Therefore, a diet containing pollen plays an important role in the intrinsic rate of increase and other growth parameters of H. hebetor parasitoids. Totally almond, date palm, rapeseed, and honeybee pollen diets were more suitable for mass rearing the parasitoid wasp.

Population fl uctuations and biodiversity of the hymenopteran parasitoid species associated with the pest were studied in six kiwi orchards in Iran, during one-year period. Parasitoid species abundance, species diversity indices and evenness indices were calculated. Most of the parasitoid species were dominant or eudominant. Based on the alpha diversity indices, the Najarkola region had high diversity and the Kharatkola region had low diversity. The Paeendasteh region (based on Simpson's Diversity on Camargo evenness indices) and the Samnakola region (based on the modifi ed Nee, and on Smith and Wilson evenness indices) were less uniform. Among the recorded parasitoids, Encarsia berlesei Howard (Hymenoptera: Aphelinidae), followed by Aphytis proclia Walker (Hymenoptera: Aphelinidae), had the highest population in all orchards.

Five species of parasitoid wasps belonging to three families including, Oomyzus sokolowskii (Kurdjumov, 1912) (Eulophidae), Pteromalus sp. (Pteromalidae), Cotesia plutellae (Kurdjumov, 1912) (Braconidae), Diadegma anurum (Thomson, 1877) and Syrphophilus bizonarius (Gravenhorst, 1829) (Ichenumonidae) were collected and identified. S. bizonarius (Ichneumonidae: Diplazontinae) representing a new genus and species record for the fauna of Iran.

Different concentrations consisted 103, 104, 105, 106, 107and 108 conidia/ml and experiment replicated 4 time. Effect of fungal suspensions of 106 and 108 conidia/ml in EC oil was also studied on sunn pest adults (aestivation population) using direct spraying method. Mortality in all of treatments was daily recorded. Results showed that isolate M14 reduced egg hatching by 40%. Estimated LC50 value for each isolates (IRAN 437C and M14) was 4.3×107 and 1.4×106 conidia/ml on adults and 4.8×104 and 2.3×103 conidia/ml on 2nd nymphal instar, respectively. Also, the calculated LT50 value using concentration of 108 conidia/ml for each isolates (IRAN 437C and M14) on adults were 29.64 and 11.9 days, and for nymphal stage were 3.23 and 2.22 days, respectively. The bioassay results showed that M14 isolate was more effective on both stages of the sunn pest. Although, nymphal stage was more susceptible compared to adult. In addition, EC oil (0.3%) decreased LT50 of M. anisopliae to 54.45 percent compared with distilled water mixed with wetting agent (Tween 80). Adding oil carriers to a fungus suspension increased the pathogenicity.
