Abstract

Several pests, such as Bemisia tabaci and Tuta absoluta, can reduce tomato (Solanum lycopersicum L.) fruit production. Selection of resistant genotypes is one important pest management method. Thus, the objective of the present study is to evaluate the relationship between acylglucose levels, an allelochemical that activates resistance against tomato pests, leaf trichome types in tomato genotypes from two segregating populations, and their association with resistance to whitefly (Bemisia tabaci) and tomato leafminer (Tuta absoluta). The treatments were genotypes F₂BC₄ and F₂ ([M08 × F₂BC₃) S. pennellii × S. lycopersicum] with contrasting levels of acylglucoses, Solanum pennellii – LA-716 (resistance pattern) and Solanum lycopersicum lineage UEL M08 and S. lycopersicum cv. Redenção (susceptibility pattern). Evaluations of the genotypes were carried out by analyzing the densities and types of trichomes. Oviposition and nymphs of B. tabaci and damage severity of T. absoluta were evaluated. Densities of glandular trichomes are positively correlated to levels of acylglucoses. The advanced genotypes with high levels of the allelochemical reduced B. tabaci nymphs and eggs and the severity of T. absoluta damage, compared to commercial material. The desired characteristic of S. pennellii is inherited throughout backcrosses. The genotypes RVTA-2010-31319-214-238-pl#427 M and RVTA-2010-31-177-177-325-pl#42R demonstrate potential to advance the tomato breeding program to obtain pest-tolerant cultivars.

具有高酰基葡萄糖水平的番茄基因型耐节肢动物害虫

一些害虫，如烟粉虱和绝对土塔，可以减少番茄（茄）果实产量。抗性基因型的选择是害虫防治的重要手段之一。因此，本研究的目的是评估酰基葡萄糖水平（一种激活番茄害虫抗性的化感化学物质）与两个分离群体中番茄基因型中的叶片毛状体类型之间的关系，以及它们与抗白蝇（烟粉虱）和番茄叶螨（绝对叶螨）的关系。处理基因型分别为F2BC4和F2 ([M08 × F2BC3) pennellis × S。用不同水平的酰基葡萄糖、秋葵LA-716（抗性模式）和茄系UEL M08和番茄葡萄球菌进行比较。redeno（易感型）。通过分析毛状体的密度和类型对基因型进行评价。评价了烟粉虱的产卵和若虫数量以及对烟粉虱的危害程度。腺毛的密度与葡萄糖水平呈正相关。与商业材料相比，具有高水平化感化学物质的高级基因型降低了烟粉虱若虫和卵，降低了绝对粉虱的危害程度。pennellii的理想特性通过回交遗传。基因型RVTA-2010-31319-214-238-pl# 427m和RVTA-2010-31-177-177-325-pl#42R显示出促进番茄育种计划获得耐虫害品种的潜力。

期刊介绍： Arthropod-Plant Interactions is dedicated to publishing high quality original papers and reviews with a broad fundamental or applied focus on ecological, biological, and evolutionary aspects of the interactions between insects and other arthropods with plants. Coverage extends to all aspects of such interactions including chemical, biochemical, genetic, and molecular analysis, as well reporting on multitrophic studies, ecophysiology, and mutualism. Arthropod-Plant Interactions encourages the submission of forum papers that challenge prevailing hypotheses. The journal encourages a diversity of opinion by presenting both invited and unsolicited review papers.
