Abstract

Research into plant proteins demonstrating insecticidal activity has found several possibilities produced by ferns in the genus Adiantum. One such protein, named IPD083Cb, exhibits activity against certain lepidopteran species. The purpose of the current study was to characterize the spectrum of activity of this protein. In total, 12 species from six families of Lepidoptera and one species of Coleoptera were evaluated for sensitivity to IPD083Cb. For all organisms evaluated, Anticarsia gemmatalis was the most sensitive species for mortality (11.2 μg IPD083CB protein per cm² diet). No biologically relevant effects of IPD083Cb were observed on survival or weight of the coleopteran Diabrotica virgifera virgifera at concentrations assessed in this study. This protein shows potential for use as a plant-incorporated protectant against lepidopteran pests in maize and soybean crops.

IPD083Cb的杀虫活性谱分析：一种来自水蛭纲植物的新型杀虫蛋白，对鳞翅目主要害虫有活性

对具有杀虫活性的植物蛋白的研究发现了几种由蕨类植物产生的可能性。其中一种名为IPD083Cb的蛋白质显示出对某些鳞翅目物种的活性。本研究的目的是表征该蛋白的活性谱。选取鳞翅目6科12种昆虫和鞘翅目1种昆虫对IPD083Cb进行敏感性评价。在所有被评估的生物中，对死亡率最敏感的物种是红雀（Anticarsia gemmatalis）（每cm2日粮中含有11.2 μg IPD083CB蛋白）。在本研究评估的浓度下，未观察到IPD083Cb对刺槐鞘翅目昆虫的生存或体重的生物学相关影响。该蛋白显示出在玉米和大豆作物中作为抗鳞翅目害虫的植物结合保护剂的潜力。

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.
