Lin & Huber (Hymenoptera: Mymaridae) was imported to Brazil in 2012, to manage the exotic pest Carpintero & Dellapé (Hemiptera: Thaumastocoridae), which has been damaging eucalyptus plantations. Knowledge of the thermal requirements and the fertility life table of is important to improve mass rearing methods for this parasitoid and the effectiveness of its release to manage . The objective was to evaluate the development period, thermal requirements and the fertility life table of at different temperatures. The egg-adult period of this parasitoid varied from 43 to 14 days at 15 °C and 30 °C, respectively. The emergence of adults was higher at 15 °C, 18 °C, 21 °C and 24 °C than at 30 °C. Female and male need 226.75 and 230.41 degree-days and temperatures higher than 10.06 °C and 9.90 °C, respectively, to complete egg-adult development. The number of parasitized eggs per female was higher at 21 °C, 24 °C and 27 °C, with 5.82, 7.73 and 5.50 eggs, respectively, than at 30 °C (0.45). longevity was greater at 15 °C, 21 °C and 24 °C. The net reproductive rate of the parasitoid was higher at 21 °C and 24 °C than at 30 °C, 3.05, 4.70 and 0.16, respectively. The finite rate of increase of was greater at 21 °C, 24 °C and 27 °C, than at 30 °C and the intrinsic rate of increase was negative at 30 °C, -0.100. The temperatures 21 °C and 24 °C and from 18 °C to 27 °C are the most adequate for the reproduction and population increase of parasitizing eggs of , respectively.
林氏寡节猛蜂（膜翅目：寡节猛蜂科）于 2012 年被引入巴西，以防治破坏桉树种植园的外来害虫 Carpintero & Dellapé（半翅目：长蝽科）。了解该寄生蜂的热需求和生殖生命表对于改进其大规模饲养方法和释放该寄生蜂以管理 Carpintero & Dellapé 至关重要。本研究旨在评估该寄生蜂在不同温度下的发育周期、热需求和生殖生命表。在 15°C 和 30°C 下，该寄生蜂的卵-成虫期分别为 43 天和 14 天。在 15°C、18°C、21°C 和 24°C 下， 成虫的羽化率高于 30°C。雌蜂和雄蜂完成卵-成虫发育分别需要 226.75 和 230.41 度日，以及高于 10.06°C 和 9.90°C 的温度。每只雌蜂寄生的卵数在 21°C、24°C 和 27°C 下较高，分别为 5.82、7.73 和 5.50 个，而在 30°C 下（0.45 个）较低。 寿命在 15°C、21°C 和 24°C 下较长。寄生蜂的净生殖率在 21°C 和 24°C 下较高，分别为 3.05、4.70 和 0.16，而在 30°C 下较低。 寄生蜂的有限增长率在 21°C、24°C 和 27°C 下较高，而在 30°C 下较低，内禀增长率在 30°C 下为负值，为-0.100。因此，21°C、24°C 和 27°C 是 寄生 Carpintero & Dellapé 卵的最适温度，分别有利于其繁殖和种群增长。
