Abstract

The Indian meal moth, Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae), is a globally significant pest of stored commodities, including hazelnuts. In this study we investigated life table parameters, consumption, and frass production of P. interpunctella on four major Turkish hazelnut cultivars: ‘Çakıldak’, ‘Mincane’, ‘Palaz’, and ‘Tombul’. The development, fecundity, consumption, and frass production were analyzed using the age-stage, two-sex life table theory. Significant differences in developmental durations were observed among the cultivars, with insects reared on Mincane exhibiting the longest preadult development period (43.51 days). No significant differences were observed in the net reproductive rate (R₀), intrinsic rate of increase (r), and finite rate of increase (λ) among cultivars. The heaviest pupae were recorded on Mincane and Tombul cultivars. Consumption and frass production rates also varied among cultivars. Larvae reared on Palaz exhibited the highest net consumption rate and the lowest net frass production rate. Population projections showed the largest population size on Tombul (>8.1 million individuals, including 4.6 million larvae) after 120 days, highlighting its potential risk in storage conditions. Notably, the highest larval population was on Mincane (>5.6 million individuals). The projected larval population size, frass, and total consumption exhibited similar lower trends on both Çakıldak and Palaz cultivars. These results highlight the significance of hazelnut cultivar selection in the context of P. interpunctella management. Specifically, Çakıldak would be the most suitable choice for integrated pest management due to its lowest preadult survival rate, along with the low predicted pest population size, frass production, and total consumption.

四种土耳其榛子主要品种间斑倍虫的生命表参数、食用量及产草量

印度餐蛾，斑间飞蛾（h bner）（鳞翅目：皮蛾科），是全球重要的储藏商品害虫，包括榛子。本研究对4个主要土耳其榛子品种Çakıldak、Mincane、Palaz和Tombul的生活表参数、食用量和产草量进行了研究。采用年龄阶段、两性生命表理论对其发育、繁殖力、消耗和产量进行了分析。不同品种昆虫的发育周期差异显著，其中明藤的成虫前期发育时间最长（43.51 d），总寿命最长（51.88 d）。品种间净繁殖率（R0）、内在增长率(r)和有限增长率（λ）无显著差异。最重的蛹记录在Mincane和Tombul品种上。食用量和产量在不同品种间也存在差异。幼虫净消耗率最高，净产草率最低。人口预测显示，曼谷的人口规模最大。120天后，有810万只，包括460万只幼虫)，这突出了其储存条件的潜在风险。值得注意的是，Mincane (>；560万人)。在Çakıldak和Palaz品种上，预测的幼虫数量、生物量和总消费量均呈现出相似的下降趋势。这些结果突出了榛子品种选择在斑间榛子管理中的重要意义。具体而言，Çakıldak是最适合虫害综合治理的选择，因为它的成虫前存活率最低，而且预测的虫害种群规模、草叶产量和总消费量也较小。

期刊介绍： The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics: -Abiotic damage- Agronomic control methods- Assessment of pest and disease damage- Molecular methods for the detection and assessment of pests and diseases- Biological control- Biorational pesticides- Control of animal pests of world crops- Control of diseases of crop plants caused by microorganisms- Control of weeds and integrated management- Economic considerations- Effects of plant growth regulators- Environmental benefits of reduced pesticide use- Environmental effects of pesticides- Epidemiology of pests and diseases in relation to control- GM Crops, and genetic engineering applications- Importance and control of postharvest crop losses- Integrated control- Interrelationships and compatibility among different control strategies- Invasive species as they relate to implications for crop protection- Pesticide application methods- Pest management- Phytobiomes for pest and disease control- Resistance management- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
