Abstract

ABSTRACT: The spotted spider mite, Tetranychus urticae (Koch, 1836), is one of the most important pests of strawberry production systems worldwide. Because plant resistance is an important integrated management strategy, the present study investigated the effects of 12 strawberry genotypes on the biological characteristics of this pest under laboratory conditions (25 ± 2 °C and RH 60 ± 10%; 12:12-hour photophase). The experiment was carried using 12 treatments (genotypes), divided into 20 replications each, in a completely randomized design. The response variables were the biological parameters of the spider mite and its survival rate. The development and survival of T. urticae were influenced by different strawberry genotypes. The Camarosa cultivar together with genotypes Selection 05 and 2017-04-03 negatively affected the development and survival of T. urticae. The Selection 02 genotype had greatest susceptibility to the spider mite, which allowed fast development and high survival rate. The reproductive parameters of T. urticae were affected differently as a function of the strawberry genotype, with the Camarosa cultivar and the genotypes Selection 05 and 2017-04-03 being unfavorable to development, suggesting a possible resistance based on antibiosis.

草莓基因型对斑点蜘蛛螨的抗生作用

摘要:斑螨(Tetranychus urticae, Koch, 1836)是全球草莓生产系统中最重要的害虫之一。由于植物抗性是一项重要的综合管理策略，本研究在实验室条件下(25±2°C, RH 60±10%;12:12-hour光照阶段)。试验采用完全随机设计，采用12个处理(基因型)，每个处理分为20个重复。响应变量为蜘蛛螨的生物学参数和存活率。不同草莓基因型对荨麻疹夜蛾的发育和存活有影响。Camarosa品种与基因型Selection 05和2017-04-03对荨麻螟的发育和存活均有不利影响。选择02基因型对螨的易感程度最高，发育快，成活率高。不同草莓基因型对荨麻疹粉蚧的生殖参数有不同的影响，其中Camarosa品种和基因型Selection 05和2017-04-03对荨麻疹粉蚧的发育不利，表明可能存在基于抗生素的抗性。
