Abstract

ABSTRACT Agonoscena pistaciae Burckhardt & Lauterer (Hemiptera: Aphalaridae) is the most important pest of pistachio trees in Iran and the world. Anthocoris minki pistaciae Wagner (Hemiptera: Anthocoridae) is a predator of A. pistaciae. Biological characteristics of this predatory bug were determined at three constant temperatures (17, 26 and 30 ± 2°C), 55 ± 5% R.H., and a photoperiod of 16:8 h (L:D). Data were analyzed by age-stage, two-sex life table to assess the variable developmental rates. Pre-adult developmental time of this predator at 17, 26 and 30°C were 24.5, 15.2 and 14.2 d, respectively. Adult longevities were 61.8, 51.9 and 43.7 d for males, and 60.3, 49.2 and 43 d for females at 17, 26 and 30°C, respectively. Fecundity at 17, 26 and 30°C were 50.3, 51.9 and 41.6 eggs/female, respectively. Intrinsic rates of increase (r) were 0.0707, 0.1042 and 0.1102 d–1 at 17, 26 and 30°C, respectively. The mean generation time (T) was 27.3 d (the shortest time) at 30°C and 42 d (the longest time) at 17°C. The net reproductive rate (R 0), the age-stage-specific fecundity (fxj), age-specific fecundity (mx) and age-specific maternity (lxmx) at 26°C were higher than those at 17 and 30°C. This research suggests that this predator can retain higher population densities at 26°C than at the other temperatures tested. Results of this study provide the biological basis for using A. minki pistaciae in a biological control program against A. pistaciae in pistachio orchards.

三恒温条件下饲养开心果蚁(半翅目:蚁科)的年龄、期、两性生命表
摘要:开心果蚜(Agonoscena piraciae Burckhardt&Lauterer,半翅目:蚜科)是伊朗和世界上最重要的开心果害虫。水貂花蝶Wagner(半翅目:花蝶科)是花蝶科的一种捕食者。在三个恒定温度(17、26和30±2°C)、55±5%R.H.和16:8 H(L:D)的光周期下测定了这种捕食性昆虫的生物学特性。数据按年龄阶段、两性生活表进行分析,以评估不同的发育率。这种捕食者在17、26和30°C的成年前发育时间分别为24.5、15.2和14.2天。在17°C、26°C和30°C下,雄性的成虫寿命分别为61.8天、51.9天和43.7天,雌性的成虫寿命则分别为60.3天、49.2天和43天。在17、26和30°C时的受精率分别为50.3、51.9和41.6个卵/雌。17°C、26°C和30°C时的固有增长率(r)分别为0.0707、0.1042和0.1102 d–1。平均生成时间(T)在30°C为27.3天(最短时间),在17°C为42天(最长时间)。26°C时的净生殖率(R0)、年龄阶段特异性生殖力(fxj)、年龄特异性生殖能力(mx)和年龄特异性生育率(lxmx)高于17和30°C时。这项研究表明,与其他测试温度相比,这种捕食者在26°C时可以保持更高的种群密度。本研究的结果为在开心果园中使用水貂开心果进行生物防治提供了生物学依据。

期刊介绍: The Journal of Agricultural and Urban Entomology (JAUE) (Journal of Agricultural Entomology, Jan 1984 - Oct 1998 volumes 1-15) is published under the auspices of the South Carolina Entomological Society (SCES). The Journal publishes contributions of original research concerning insects and other arthropods of agricultural and urban importance to include those affecting humans, livestock, poultry, and wildlife. JAUE is particularly dedicated to the publication of articles and notes pertaining to applied entomology, although it will accept suitable contributions of a fundamental nature related to agricultural and urban entomology.
