Abstract : The mango pest Oligonychus mangiferus was collected in an orchard in Gujarat, India, and its biology was studied in the laboratory in March-May 1986 at 22-31°C. The incubation period averaged 4.65 days. The larval, protonymph and deutonymph stages averaged 1.16, 1.13 and 1.17 days, respectively, for females and 0.97, 1.02 and 1.07 days for males. The combined larval-nymphal period averaged 5.93 days for females and 5.08 days for males. The preoviposition period averaged 2.20 days, and each female laid an average of 10.67 eggs during the oviposition period, which averaged 5.80 days. Of the eggs laid, 90-100% hatched. The adult lifespan averaged 10.11 days for females and 4.21 days for males.
