Investigation was undertaken at Department of Entomology, College of Agriculture, Dharwad (Karnataka) during 2018-19 to understand the biology of Bactrocera dorsalis (Hendel) on different mango genotypes under laboratory condition. The data on comparative biology of B. dorsalis on different genotypes inferred that, the minimum incubation period of 1.5 days was noticed on Alphonso, whereas, it was maximum on Dasheri (3.5days). The minimum maggot period of 7.8 days was noticed on Benishan, whereas, it was maximum on Dasheri (11.3days). The minimum pupal period was recorded on Benishan (10.3 days), while it was maximum of 12.6 days on Dasheri. Among the eight genotypes the adult male longevity was recorded on Benishan and female on Alphonso i.e. (20.6 and 23.9 days) Minimum male and female longevity was on Dasheri (18.3 and 20.4 days). The total development period was significantly highest on Dasheri (27.5 days) and it was found to be minimum on Benishan (19.8 days). The maximum mean fecundity was 189.5 eggs per female on Benishan whereas, minimum with 132.7 eggs per female on Dasheri genotype.
