Abstract

Tenebrio molitor L. (Coleoptera: Tenebrionidae) and Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae) are harmful pests in storages. Carlina acaulis L. (Asteraceae) is a medicinal plant used for its beneficial effects throughout central-eastern Europe. Its essential oil (EO), almost entirely made up of carlina oxide, exhibited broad-spectrum properties, including notable pesticidal activity against vectors and agricultural or stored-product pests. This research examined the impact of sublethal concentrations of carlina oxide on the mating behavior of T. molitor and S. zeamais. Sitophilus zeamais adults were more sensitive to carlina oxide than T. molitor adults, as LC10, LC30, and LC50 values were lower. The mating success of T. molitor and S. zeamais was impacted negatively by the exposure of both beetles to sublethal concentrations (LC10 and LC30) of carlina oxide. For both species, the mean duration of each mating phase was significantly affected by exposure to sublethal concentrations of carlina oxide vs. control. The highest mean duration of copulation was recorded in control pairs, which was significantly longer than pairs treated with LC10 and LC30 of both species. Concerning lateralization, males of both species showed a left-biased trend, which led to higher successful copulations than right-biased, front or back-side males, regardless of treatment or control. Overall, carlina oxide alters the behavioral traits against T. molitor and S. zeamais, thus, it should be further considered in Integrated Pest Management (IPM) approaches in the storage environment.

氧化胭脂虫亚致死浓度对黄粉拟黄粉虫和玉米象的求偶和交配性状有影响

黄粉步甲（鞘翅目：黄粉步甲科）和玉米象甲（鞘翅目：黄粉步甲科）是仓库中的有害害虫。Carlina acaulis L.（菊科）是一种药用植物，用于整个中欧和东欧的有益作用。其精油（EO）几乎完全由氧化carlina组成，具有广谱特性，对病媒和农业或储存产品害虫具有显著的杀虫活性。本研究考察了亚致死浓度的氧化胭脂虫对玉米螟和玉米螟交配行为的影响。玉米象成虫对氧化卡丽娜的LC10、LC30和LC50值较低，对氧化卡丽娜的敏感性高于玉米象成虫。暴露于亚致死浓度（LC10和LC30）的carlina氧化物对T. molitor和S. zeamais的交配成功率有负向影响。对于这两个物种，每个交配期的平均持续时间都受到暴露于亚致死浓度的氧化carlina与对照的显著影响。对照组的平均交尾时间最长，显著长于LC10和LC30处理的交尾时间。在偏侧性方面，两种雄虫均表现出偏左的倾向，其交配成功率高于偏右的雄虫。综上所述，氧化carlina改变了玉米螟和玉米螟的行为特征，因此，在虫害综合治理（IPM）方法中应进一步考虑氧化carlina。

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.
