Abstract

Onion thrips, Thrips tabaci Lind. (Thysanoptera: Thripidae) is a major pest of onion worldwide. It damages onion, Allium cepa L., both directly and indirectly, which leads to significant output losses. In 2022, research was conducted in a private onion field in the Delta region, Egypt, to evaluate the efficacy of bioinsecticides and synthetic insecticides and to evaluate the efficacy of macro- and micronutrient in determining treatment effects on onion thrips populations.

Injury caused by onion thrips is often not severe enough to warrant the application of numerous pesticides to crops in the Delta region of Egypt. Spinosad (Tracer 24% SC) and spinetoram (Radiant 12% SC) were used as bioinsecticides, and Pyridalyl (Pleo 50% EC) was used as a synthetic insecticide for managing onion thrips populations. The greatest decrease in infestation was achieved by the application of the chemical insecticide (Pyridalyl) Pleo 50% EC and the bioinsecticide (Spinosad) Tracer 24% SC. The greatest decrease in infestation was achieved by the application of the micronutrient boron.

生物杀虫剂、合成杀虫剂、宏观和微观营养元素对防治洋葱蓟马的功效：田间试验

洋葱蓟马（Thrips tabaci Lind.(Thysanoptera: Thripidae）是全世界洋葱的主要害虫。它直接或间接地危害洋葱（Allium cepa L.），导致严重的产量损失。2022 年，在埃及三角洲地区的一块私人洋葱田里开展了一项研究，以评估生物杀虫剂和合成杀虫剂的功效，并评估宏观和微观营养元素在确定洋葱蓟马种群处理效果方面的功效。在埃及三角洲地区，洋葱蓟马造成的伤害通常并不严重，不足以对作物施用大量杀虫剂。Spinosad（Tracer 24% SC）和 spinetoram（Radiant 12% SC）被用作生物杀虫剂，Pyridalyl（Pleo 50% EC）被用作合成杀虫剂，用于控制洋葱蓟马的数量。使用化学杀虫剂（哒螨灵）Pleo 50%EC和生物杀虫剂（斯皮诺沙得）Tracer 24% SC能最大程度地减少虫害。施用微量营养元素硼能最大程度地减少虫害。

期刊介绍： Gesunde Pflanzen publiziert praxisbezogene Beiträge zum Pflanzenschutz in Landwirtschaft, Forstwirtschaft, Gartenbau und öffentlichem Grün und seinen Bezügen zum Umwelt- und Verbraucherschutz sowie zu Rechtsfragen. Das Themenspektrum reicht von der Bestimmung der Schadorganismen über Maßnahmen und Verfahren zur Minderung des Befallsrisikos bis hin zur Entwicklung und Anwendung nicht-chemischer und chemischer Bekämpfungsstrategien und -verfahren, aber auch zu Fragen der Auswirkungen des Pflanzenschutzes auf die Umwelt, die Sicherung der Ernährung sowie zu allgemeinen Fragen wie Nutzen und Risiken und zur Entwicklung neuer Technologien. Jedes Heft enthält Originalbeiträge renommierter Wissenschaftler, aktuelle Informationen von Verbänden sowie aus der Industrie, Pressemitteilungen und Personalia. Damit bietet die Zeitschrift vor allem Behörden und Anwendern im Agrarsektor und Verbraucherschutz fundierte Praxisunterstützung auf wissenschaftlichem Niveau.
