Abstract

The biology of mango fruit borer, Deanolis albizonalis (Hampson) Viz., egg, Larval instars, pupa and Adult have been studied for the first time on mango at Department of Entomology Regional Fruit Research Station, Dr. B.S.K.K.V., Vengurle. Average length and breadth of the eggs were 0.96±0.031 and 0.47±0.030 mm, respectively. First, second, third, fourth and fifth instar larvae measured in length as 1.96±0.04 mm, 4.02±0.42 mm, 13.42±1.22mm, 18.67±0.86mm and 29.60±1.83 mm and in breadth 0.24±0.02mm, 0.61±0.05mm, 1.58±0.08mm, 1.96±0.25 mm, 3.16±0.24 mm, respectively. Larval period completed in 13.83 ± 1.18 days through five instars. The average length and breadth of pre-pupa was 23.37 ± 2.04 mm and 14.38 ± 3.04 mm, respectively. The average length and breadth of pupa was 15.25± 0.65mm and 4.02 ± 0.42mm. The average pre-pupal and pupal stage lasts for 2.29 ± 0.56 days and 4.39 ± 0.64 days, respectively. Adult moths have a wingspan of 24 to 28 mm. Total life cycle of the D. albizonalis was 25 to 29 days, respectively.
