The vegetable leaf miner (Liriomyza sativae) is considered one of the main melon pests, causing serious problems for producers in all growing regions. A promising type of pest control has been use of resistant cultivars, in isolation or associated with other types of control. This study aimed to evaluate the resistance of melon genotypes to L. sativae. Twenty-one melon genotypes and one commercial "Goldex" hybrid (susceptibility pattern) were evaluated in two experiments. In the first experiment, we observed the non-preference of L. sativae for oviposition and feeding by quantifying the number of eggs and feeding punctures, both on the adaxial side and on the abaxial face of the leaves. In the second experiment, we observed the antibiosis effect through L. sativae larval and pupal viability. Genotype CNPH 06-1047-341 showed the lowest preference for oviposition (high resistance), with low egg values on both leaf sides (0.3 eggs/plant). In genotypes CNPH 06-1047-313, CNPH 06-1047-346, CNPH 11-1071-27, CNPH 11-1071-39, CNPH 11-1071-43, and CNPH 11-1071-53, we observed a higher preference for the adaxial side, whereas for the other genotypes and the commercial hybrid there was no discrimination between leaf sides. In relation to antibiosis, genotypes CNPH 06-1047-339, CNPH 06-1047-333, CNPH 06-1047-330, CNPH 06-1047-334, CNPH 06-1047-331, CNPH 06-1047-343, CNPH 10-1056-313, CNPH 06-1047-346, and CNPH 06-1047-341 presented lower larval and pupal viability. Genotype CNPH 06-1047-341 was the least preferred for oviposition and feeding and the most promising as a source of resistance to L. sativae.
蔬菜叶潜蝇（Liriomyza sativae）被认为是主要的瓜类害虫之一，给所有种植地区的生产者造成了严重问题。一种有前景的害虫防治方法是使用抗性品种，单独使用或与其他类型的防治方法结合使用。本研究旨在评估甜瓜基因型对 L. sativae 的抗性。在两个实验中，评估了 21 个甜瓜基因型和一个商业“Goldex”杂交种（敏感性模式）。在第一个实验中，我们通过量化叶片的正面和背面的产卵和取食的卵和取食穿孔的数量，观察到 L. sativae 对产卵和取食的非偏好性。在第二个实验中，我们通过 L. sativae 幼虫和蛹的存活率观察抗生性效应。基因型 CNPH 06-1047-341 对产卵的偏好性最低（高抗性），两侧叶片上的卵值都很低（每株 0.3 个卵）。在基因型 CNPH 06-1047-313、CNPH 06-1047-346、CNPH 11-1071-27、CNPH 11-1071-39、CNPH 11-1071-43 和 CNPH 11-1071-53 中，我们观察到对正面的偏好性更高，而对于其他基因型和商业杂交种，叶片两侧没有差异。关于抗生性，基因型 CNPH 06-1047-339、CNPH 06-1047-333、CNPH 06-1047-330、CNPH 06-1047-334、CNPH 06-1047-331、CNPH 06-1047-343、CNPH 10-1056-313、CNPH 06-1047-346 和 CNPH 06-1047-341 的幼虫和蛹的存活率较低。基因型 CNPH 06-1047-341 对产卵和取食的偏好性最低，是最有希望的抗 L. sativae 源。
