Insects use floral volatiles as the olfactory cues to locate flowers. Numerous studies have shown that the selection behavior of insects can be impacted by variations in the volatile component concentration of floral varieties. The flower of mango (Mangifera indica L.) rely on insect pollination and susceptible to florivorous pests. However, volatiles in different varieties of mango flowers are relatively insufficient, which is unfavourable to the development of attractants and repellents. Therefore, the volatile floral chemical components in seven mango varieties (M. indica var. Sijimi, M. indica var. Tainong 1, M. indica var. Guire 82, M. indica var. Kaite, M. indica var. Hongmang 6, M. indica var. Hongxiangya, and M. indica var. Jinhuang) were collected using the dynamic headspace adsorption technique. The volatile components were identified and analyzed using gas chromatography-mass spectrometry-mass spectrometry (GC-MS) to compare the composition differences and similarities of the components. The findings indicated that a total of 115 volatile components, comprising 44 terpenes, 30 alkanes, 16 esters, 16 alcohols, five ketones, three aldehydes, and one phenol, were found in the volatiles of the seven species of mango flowers. 82 distinct types of volatile substances were discovered in M. indica var. Sijimi, 49 distinct types of M. indica var. Tainong 1, 46 distinct types of M. indica var. Guire 82, 49 distinct types of M. indica var. Kaite, 60 distinct types of M. indica var. Hongmang 6, 49 distinctive types of M. indica var. Hongxiangya, and 59 distinct types of M. indica var. Jinhuang. Seven species of mango blossoms contained 14 common volatile components: α-pinene, camphene, β-pinene, β-myrcene, 3-carene, α-terpinene, D-limonene, β-ocimene, terpinolene, 1-caryophyllene, germacrene D, o-cymene, benzoic acid, ethyl ester and 2-propyl-1-pentanol; 33 different types of specific components existed, including 24 different types of M. indica var. Sijimi, four different types of M. indica var. Tainong 1, two different types of M. indica var. Jinhuang, one type of M. indica var. Guire 82, M. indica var. Hongmang 6, and M. indica var. Kaite. The volatile compounds of mango flowers had higher relative concentrations of terpenes (46.15%–89.41%), alcohols (2.01%–23.58%), esters (3.34%–14.67%), and alkanes (2.27%–13.75%). The most abundant terpenes were α-pinene, 3-carene and terpinolene, the most abundant alcohols was linalool. The most abundant esters were benzoic acid, ethyl ester, and the most abundant alkanes were cyclohexasiloxane, dodecamethyl. The flower volatilesof M. indica var. Sijimi and M. indica var. Jinhuang had highest similarity of 0.862 among seven mango species; and that of M. indica var. Sijimi and M. indica var. Hongxiangya had the lowest similarity of 0.255. The findings would provide a reference for flower-volatile-mediated behavior preference researches in pollination insects and florivorous pests to various mango varieties.
