Abstract

The efficiency of pistachio nuts was investigated on the multiplication of Ectomyelois ceratoniae (Zeller) (Lep: Pyralidae) by rearing a cohort of 61 eggs individually at 26 ± 1 ℃, 60 ± 10% RH, and 16:8 h L:D. The age-stage two-sex life table theory and bootstrapping were used to analyze the data. The survival probability from a newly born egg to larva, pupa, and male and female adults was 0.77, 0.52, and 0.26 and 0.24, respectively. The total immature duration of males (45.33 d) was significantly shorter than that of females (49.47 d). The mean female fecundity was 98.08 eggs/fertile female (n = 12) and 78.46 eggs/all females (n = 15), respectively. The life expectancy of a newborn E. ceratoniae was 34.83 d, and the reproductive value was 79.63 at age 49 d of the female. Female moths had slightly longer longevity (7.82 d) compared with males (7.58 d). The population parameters R₀, r, and λ were 19.29 offspring, 0.0548 d⁻¹, and 1.0563 d⁻¹, respectively. When eggs are harvested and the discard age is 62 d, the maximum harvest rate is 0.9481. Therefore, for a daily harvest of 10,000 eggs, the daily recruits of 547 eggs, 421 larvae, 287 pupae, 134 females, and 143 males are required in a stable stage structure rearing system. Each larva damaged and fed upon 2 gr. of raw pistachio to complete its development. Consequently, about 842 gr. pistachio nuts must be provided daily to meet the larval feeding demand, which imposes a cost of about $10 (local retail price) to the rearing system as nutritional provision.

在开心果上饲养角豆夜蛾（Ectomyelois ceratoniae (Zell.)）：生物学和统计学方法

通过在 26 ± 1 ℃、60 ± 10% 相对湿度和 16:8 h 长:短时间条件下单独饲养一组 61 枚卵，研究了开心果对 Ectomyelois ceratoniae (Zeller) (Lep: Pyralidae) 的繁殖效率。采用年龄-阶段双性生命表理论和引导法对数据进行分析。从初生卵到幼虫、蛹、雌雄成虫的存活概率分别为 0.77、0.52、0.26 和 0.24。雄性的总未成熟期（45.33 d）明显短于雌性（49.47 d）。雌性的平均受精率分别为 98.08 个卵/可育雌性（n = 12）和 78.46 个卵/所有雌性（n = 15）。新生铈娥蛾的预期寿命为 34.83 d，雌蛾 49 d 时的生殖值为 79.63。雌蛾的寿命（7.82 d）略长于雄蛾（7.58 d）。种群参数 R0、r 和 λ 分别为 19.29 个后代、0.0548 d-1 和 1.0563 d-1。当采卵弃卵龄为 62 d 时，最大采卵率为 0.9481。因此，在一个稳定阶段结构的饲养系统中，如果每天收获 10,000 粒卵，则每天需要繁殖 547 粒卵、421 只幼虫、287 只蛹、134 只雌虫和 143 只雄虫。每只幼虫要吃 2 克生开心果才能完成发育。因此，每天必须提供约 842 克开心果才能满足幼虫的喂食需求，这就给饲养系统带来了约 10 美元（当地零售价）的营养供应成本。

期刊介绍： Phytoparasitica is an international journal on Plant Protection, that publishes original research contributions on the biological, chemical and molecular aspects of Entomology, Plant Pathology, Virology, Nematology, and Weed Sciences, which strives to improve scientific knowledge and technology for IPM, in forest and agroecosystems. Phytoparasitica emphasizes new insights into plant disease and pest etiology, epidemiology, host-parasite/pest biochemistry and cell biology, ecology and population biology, host genetics and resistance, disease vector biology, plant stress and biotic disorders, postharvest pathology and mycotoxins. Research can cover aspects related to the nature of plant diseases, pests and weeds, the causal agents, their spread, the losses they cause, crop loss assessment, and novel tactics and approaches for their management.
