Abstract

The whitefly, Bemisia tabaci Mediterranean (MED), is an invasive pest of several crops, including soybeans. The objective of this study was to evaluate the resistance of soybean genotypes to B. tabaci MED, in addition to the influence of possibly related physical and morphological factors. A no-choice test was carried out with 90 soybean genotypes. Subsequently, 35 materials were selected for further no-choice and multiple-choice tests. Trichomes and leaf color of plants were observed, with the aim of correlating these factors with the preference and colonization of B. tabaci MED. The genotypes KS 4202, TMG 1188 RR, M 7739 IPRO, 65l65 IPRO, and PI 229358 were the least preferred by adults of B. tabaci MED. In the multiple-choice test, the lowest numbers of eggs and nymphs per square centimeter were observed for the genotypes Dowling, PI 229358, IAC 24, KS 4202. The genotypes IAC 19, TMG 1288 RR, TMG 1182 RR, 99R09, Dowling, and TMG 2375 IPRO presented the lowest numbers of eggs and nymphs in the no-choice assay. Plants with higher trichome density were preferred by adults of B. tabaci MED and, consequently, were more heavily colonized by these insects. Plants with leaves of lower luminosity and reduced green and yellow intensity were more attractive to the whiteflies. In summary, genotypes IAC 24, IAC 19, Dowling, 99R09, TMG 1182 RR, TMG 1288 RR and TMG 2375 IPRO exhibited lower colonization by B. tabaci MED in both assays, thus indicating their potential as promising sources of resistance to B. tabaci MED.

物理和形态因素对 Bemisia Tabaci MED 在大豆基因型中的偏好和定殖的影响

地中海粉虱（MED）是包括大豆在内的多种作物的入侵害虫。本研究的目的是评估大豆基因型对地中海粉虱的抗性，以及可能相关的物理和形态因素的影响。对 90 个大豆基因型进行了无选择试验。随后，选择了 35 个材料进行进一步的无选择和多选择试验。对植株的毛状体和叶片颜色进行了观察，目的是将这些因素与 B. tabaci MED 的偏好和定殖联系起来。基因型 KS 4202、TMG 1188 RR、M 7739 IPRO、65l65 IPRO 和 PI 229358 最不受茶青虫 MED 成虫的喜欢。在多项选择测试中，基因型 Dowling、PI 229358、IAC 24 和 KS 4202 的每平方厘米卵数和若虫数最少。在无选择试验中，基因型 IAC 19、TMG 1288 RR、TMG 1182 RR、99R09、Dowling 和 TMG 2375 IPRO 的卵数和若虫数最少。毛状体密度较高的植株更受烟粉虱 MED 成虫的青睐，因此这些昆虫的定殖量也更大。叶片亮度较低、绿色和黄色强度降低的植物对粉虱更有吸引力。总之，基因型 IAC 24、IAC 19、Dowling、99R09、TMG 1182 RR、TMG 1288 RR 和 TMG 2375 IPRO 在两种试验中都表现出较低的烟粉虱定植率，从而表明它们有可能成为烟粉虱的抗性来源。

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.
