Abstract:
The biology of leaf gall midge, Procontarinia matteiana Kieffer & Cecconi on mango was studied in the laboratory of Department of Agricultural Entomology, B. A. College of Agriculture, AAU, Anand during March-April, 2018. The female of P. matteiana laid watery yellow coloured eggs on mango leaf with average incubation period of 2.25 + 0.35 days. The first instar maggots were white in colour whereas second and third instar maggots were yellow in colour. The first, second and third instar maggots period was 1.10±0.21, 2.10±0.39 and 3.20±0.67 days, respectively with total maggot period of 6.40±1.05 days. The pupae were yellow in colour, having average pupal period as 6.15±0.82 days. Pupation completed inside the galls. Male gall flies were comparatively smaller than female. The average pre-oviposition, oviposition and post-oviposition periods were 1.00±0.24, 1.20 + 0.35 and 1.05 + 0.16 days, respectively. The longevity of male and female was 2.70±0.42 and 4.30±0.39 days, respectively. The average fecundity of female fly was 8.20±0.92 eggs. The average longevity of the adult male and female were 2.30±0.35 and 3.60±0.37 days, respectively. The total life period of male and female adult of P. matteiana was 15.80±0.79 and 18.80±1.23 days, respectively. The average sex ratio (male: female) of P. matteiana was found 1: 0.84.
