Abstract:

The oriental fruit fly Bactrocera dorsalis (Hendel) is a very serious pest of fruit crop or trees, globally causing considerable economic losses. The present investigation on biology and biometrics of B. dorsalis was studied on custard apple under laboratory conditions at Department of Agricultural Entomology, Gandhi Krishi Vignana Kendra (GKVK), University of Agricultural Sciences, Bengaluru, Karnataka during 2015-16. During the period of investigation the mean maximum and minimum temperatures recorded was 28.5ºC and 19.1ºC respectively, with a relative humidity of 71.3 per cent. The experimental results revealed that average length and breadth of egg, full-grown maggots and pupae were about 1.36±0.12 mm and 0.25±0.13 mm, 8.18±0.84 and 2.25±0.70 mm, 4.08±0.58 mm and 1.82±0.69 mm respectively and length of adult flies measured about 6.20±0.73 and 8.13±0.69 mm in male and female respectively. The biological study revealed that developmental period from immature to adult stages is varied from 18 to 23 days with the mean fecundity of 12.4±2.54 eggs/day.
