Abstract

Chili pepper is a vegetable of worldwide economic and gastronomic importance. The psyllid, , is an economically important pest in this crop, causing considerable losses in its production. Currently, the application of insecticides is the main way to control . However, the use of varieties resistant to this insect is a viable alternative for its control and management. In this work, the oviposition rate, development, and survival of in two native varieties of chili were evaluated. Choice and non-choice trials showed that the oviposition was reduced on CJ-2018 by 92.17 and 80.18%, respectively, compared to the control. In CM-334, the insect showed a behavior similar to the control in the non-choice test, while in the choice test it laid more eggs on CM-334 compared to the control. The development and survival assay showed that only 1.33% of the eggs managed to reach the adult stage on CJ-2018. In contrast, on CM-334 the survival of was similar to the control. These results suggest that CJ-2018 presented a resistance based on antixenosis and antibiosis against .

摘要

辣椒是一种具有全球经济和美食重要性的蔬菜。木虱是这种作物上具有经济重要性的害虫，会导致其产量遭受相当大的损失。目前，施用杀虫剂是控制木虱的主要方法。然而，使用对这种昆虫具有抗性的品种是控制和管理它的一种可行选择。在这项研究中，评估了木虱在两个本地辣椒品种上的产卵率、发育情况和存活率。选择性和非选择性试验表明，与对照相比，木虱在CJ - 2018上的产卵量分别减少了92.17%和80.18%。在CM - 334中，在非选择性试验中该昆虫表现出与对照相似的行为，而在选择性试验中，与对照相比它在CM - 334上产的卵更多。发育和存活分析表明，在CJ - 2018上只有1.33%的卵能够发育到成虫阶段。相比之下，在CM - 334上木虱的存活率与对照相似。这些结果表明，CJ - 2018对木虱表现出基于排趋性和抗生性的抗性。
