“…The genotypes were selected based on preliminary tests of resistance of the melon plants to L. sativae, with the Goldex commercial hybrid used as the standard for susceptibility, and the CNPH 06-1047-343, CNPH 06-1047-333 and CNPH 06-1047-341 genotypes resistant through antibiosis to L. sativae (de Oliveira et al 2021). These accessions were provided by the germplasm bank of Embrapa Hortaliças, in Brasília.…”

“…In order to minimise these problems, and keep the leafminer population below the level of economic damage, new management approaches have been investigated, such as the selection of resistant melon genotypes (Celin et al 2017, Celin et al 2018, Oliveira et al, 2021.…”

“…Many factors may be related to the non-preference of Liriomyza adults for the melon, such as the release of chemical compounds by the plant, the thickness of the epidermis, the stiffness and thickness of the leaf cuticle, the density of the palisade and spongy tissue, and the number of trichomes, among others (Theobald et al 1979, Wei et al 2000, Oliveira et al, 2021. According to Kang et al (2009), the chemical compounds synthesised by plants may be fundamental to plant selection in leafminer species.…”

“…In tomato genotypes (Solanum lycopersicum L.), the nonpreference of Liriomyza trifolii for feeding is related to high levels of allelochemicals (acylsugars, 2-tridecanone) (Silva et al 2017). In the melon, L. sativae is associated with the smaller number of trichomes and greater thickness of the leaf epidermis (de Oliveira et al, 2021).…”

“…In fact, the CNPH 06-1047-343 and CNPH 06-1047-341 genotypes express antixenotic characteristics to the feeding and oviposition of L. sativae. Furthermore, CNPH 06-1047-341 and CNPH 06-1047-333 are antibiotics to the insect, as they support low rates of larval viability(Oliveira et al 2021).…”

The aim of this study was to evaluate whether volatile compounds released by melon genotypes interfere in the attractiveness and repellency of Liriomyza sativae Blanchard (Diptera: Agromyzidae), and to characterise the phenolic compounds of melon genotypes, as well as the antibiotic action of these compounds on L. sativae. Through experiments, it was shown that the volatiles of the melon genotypes CNPH 06-1047-343, CNPH 06-1047-333 and CNPH 06-1047-341 showed little attractiveness to L. sativae, while the volatiles of the Goldex commercial hybrid were more attractive. By analysing the volatile profiles, it was possible to identify the compounds acetic acid, (Z)-3-hexen-1-ol, α-pinene, (Z)-β-ocimene, (E)-β-ocimene, linalool, allo-ocimene and neo-allo-ocimene. The CNPH 06-1047-343, CNPH 06-1047-333 and CNPH 06-1047-341 melon genotypes show resistant characteristics due to the non-preference of L. sativae because of the smaller number of volatiles and the higher concentration of acetic acid in their volatile composition. The phenolic compounds characterised were hydroxybenzoic-hexoside acid, ferulic acid and trihydroxy-octadecadienoic acid. The CNPH 06-1047-333 and CNPH 06-1047-341 melon genotypes presented, respectively, the highest and lowest levels of total phenolics, but there was no difference in the larval or pupal viability of L. sativae, indicating a lack of any relationship between total phenols and antibiotic resistance of the melon genotypes to L. sativae. In general, based on the analysis of volatile and phenolic compounds, the CNPH 06-1047-343, CNPH 06-1047-333 and CNPH 06-1047-341 genotypes are less attractive to L. sativae than the commercial hybrid genotypes (Goldex).
