Habrobracon hebetor (Say) (Hymenoptera: Braconidae) is an important ectoparasitoid for biological control of several lepidopteran insect pests. The present research evaluated plant-herbivore-parasitoid interactions with H. hebetor and Ectomyelois ceratoniae (Zeller) on five commercial cultivars of pomegranate (Punica granatum L.), including Esfahani-Daneghermez and Malase-Danesyah (relatively resistant), Gabri and Tafti (moderately susceptible) and Shahvare-Danesefid (relatively susceptible) under controlled conditions as follows: 30 ± 1 °C, 60 ± 5% RH with a photoperiod of 14:10 (L:D) h. Significant differences were observed in the demographical parameters of H. hebetor on different pomegranate cultivars. The shortest immature development time of parasitoid wasp was detected on Shahvare-Danesefid cultivar, and the longest period was on Malase-Danesyah and Esfahani-Daneghermez cultivars. Fecundity rate was the highest on Tafti and Shahvare-Danesefid cultivars and the lowest on Malase-Danesyah. Furthermore, there were no significant differences among pomegranate cultivars in the gross reproductive rate (GRR) and net reproductive rate (R0) parameters of H. hebetor. The highest value of intrinsic rate of increase (r) was observed on Shahvare-Danesefid (0.249 d−1), and the lowest was on Malase-Danesyah (0.196 d−1). Significant positive or negative relationships were observed between the life history parameters of H. hebetor and the biochemical traits of pomegranate cultivars. Shahvare-Danesefid cultivar was found to be a more appropriate host than other cultivars to develop H. hebetor. These results may provide fundamental data to further understand pomegranate-carob moth-parasitoid wasp relationships. Most importantly, our findings indicated that dynamic variations in the quality of host plant affected the performance and multitrophic communications behavior of H. hebetor.

Habrobracon hebetor (Say) (Hymenoptera: Braconidae) 寄生在不同石榴品种上的 Ectomyelois ceratoniae (Zeller) (Lepidoptera: Pyralidae)

Habrobracon hebetor (Say) (膜翅目： Braconidae) 是一种重要的外寄生物，用于生物防治几种鳞翅目害虫。本研究评估了植物-食草动物-寄生物与 H. hebetor 和 Ectomyelois ceratoniae (Zeller) 在五种商业石榴品种 (Punica granatum L.) 上的相互作用，包括 Esfahani-Daneghermez 和 Malase-Danesyah（相对抗性）、Gabri 和 Tafti（中度敏感）和 Shahvare-Danesefid（相对易感）在如下受控条件下：30 ± 1 °C，60 ± 5% RH，光周期为 14:10 (L:D) h。在不同的石榴品种上观察到 H. hebetor 的人口统计学参数存在显着差异。在Shahvare-Danesefid品种上检测到寄生蜂的最短未成熟发育时间，最长的时期出现在 Malase-Danesyah 和 Esfahani-Daneghermez 品种上。Tafti 和 Shahvare-Danesefid 品种的繁殖率最高，而 Malase-Danesyah 的繁殖率最低。此外，石榴品种的总繁殖率（GRR）和净繁殖率（R0）参数在石榴品种之间没有显着差异。在 Shahvare-Danesefid (0.249 d-1) 上观察到内在增长率 (r) 的最高值，在 Malase-Danesyah (0.196 d-1) 上观察到最低值。H. hebetor 的生活史参数与石榴品种的生化性状之间观察到显着的正相关或负相关。发现 Shahvare-Danesefid 品种比其他品种更适合开发 H. hebetor。这些结果可能为进一步了解石榴-角豆蛾-寄生蜂的关系提供基础数据。最重要的是，我们的研究结果表明寄主植物质量的动态变化会影响 H. hebetor 的性能和多营养通信行为。
