**8. Discussion**

The average egg, maggot, pupal, and adult period were 1.3, 4.4, 7.3, and 2.0 days in *J. sambac*. The findings were in agreement with previous reports that cecidomyiid eggs hatched in 1.4 days, and the larval stage lasted 4–5 days, and adults emerged in 7–8 days [13]. Previous research works studied on the life stages of *C. maculipennis* and evolved the same results [14]. While comparing the biology in different *Jasminum* species, the egg period was highest (1.3 days) in *J. sambac* and least (1.1 days) in *J. grandiflorum* and *J. nitidum.* The trend was similar to other stages also. The total life cycle was highest (15.4 days) in *J. sambac* and least (13.4 days) in *J. nitidum* [15]. The longest duration of midges on *J. sambac* revealed the presence of physical factors like bud shape and size or chemical factors like high phenols, lower protein, and sugars that impair the faster growth and development. Host plants adversely affect the biology of the phytophagous insect, reducing the size, longevity, fecundity, and increasing mortality or alternatively may indicate that midges do not prefer to feed on *J. auriculatum, J. grandiflorum,* and *J. nitidum.*
