Abstract
Life history and reproductive parameters of the mango red spider mite, Oligonychus mangiferus (Rahman and Sapra) (Acari: Tetranychidae) were studied to investigate its response to different temperatures (25, 28 and 31 ºC), with 70 ± 5% R.H. on Mangifera indica L. Baladi variety in the laboratory. The results showed that the developmental time of the individuals shortened with increasing temperature. The total immature stages was the longest period (7.51 day for the female and 7.46 day for the male) at 25 ºC, while at 31°C was the shortest period (6.48 and 6.46 day, respectively). The life cycle was the longest period (12.18 day for the female and 11.71 day for the male) at 25 ºC, while at 31°C was the shortest period (10.78 and 10.38 day, respectively). So, the mean generation time was the longest (20.12 days) at 25 °C, followed by 28 °C (19.06 days) and then at 31°C was the shortest (17.87 days). On the contrary, total fecundity was 32.50 eggs (2.05 eggs/♀/day) at 25 ºC, then at 28 °C it reached 30.17 eggs (2.01 eggs/♀/day) and 26.83 eggs (1.93 eggs/♀/day) at 31°C, respectively. The mean generation time recorded the shortest (17.87 days) at 31°C, while the fecundity recorded the highest rate at 25 ºC (32.50 eggs; 2.05 eggs/♀/day). Based on these results, we can predict the presence of O. mangiferus on mango. Therefore, it should be easily to determine the best time to control this pest.
