*Life Cycle and Development of Diptera*

*J. sambac* is an evergreen vine or shrub reaching up to 0.5–3 m (1.6–9.8 ft) tall. The plant produces flowers all throughout the year in clusters of 3–12 together at the ends of branches. They are strongly scented flowers with a white corolla. The flowers open at night (usually around 6–8 in the evening). The sweet, heady fragrance of *J. sambac* is its distinct feature (**Figure 1**). It is widely grown throughout the tropics from the Arabian Peninsula to Southeast Asia and the Pacific Islands as an

*J. auriculatum* is a species of jasmine, in the family Oleaceae. It is found in India and other Asian countries. It is cultivated commercially in India and Thailand for its commercial oil. It is used for decorative purposes in occasions and festivals in India. It is a small climbing bushy plant with simple ovate dark green small leaves and small white flowers. Leaves are opposite, sometimes hairless, simple, or trifoliolate. Lateral leaflets are much smaller, rarely exceeding 4 mm in diameter, the central one up to 3.5 cm long and 1.5 cm broad, ovate, shortly pointed. Flowers are fragrant in many-flowered cymes. Flower stalks are up to 5 mm long. Flowers are white, tube 1.5 cm long, lobes elliptic, up to 8 mm long. Berry is 5 mm in diameter, globose, black (**Figure 2**) [8].

The leaves are opposite, 5–12 cm long, with 5–11 leaflets in pinnate form. The flowers are produced in open cymes, and the individual flowers are white having corolla with a basal tube 13–25 mm long and five lobes 13–22 mm long. The flower's fragrance is unique and sweet. It is widely cultivated as an ornamental plant in warm temperate and subtropical regions. The Jasmine Concrete and Jasmine Oleoresin (sold as Jasmine Absolute) were extracted by solvent extraction method. Both products have a huge demand in the fragrance industry (**Figure 3**). Methyl jasmonate isolated from the jasmine oil of *J. grandiflorum* has led to the discovery of the molecular structure of the jasmonate plant hormones [9].
