Title

BIOLOGY AND DEMOGRAPHY OF THE DUBAS BUG, OMMATISSUS LYBICUS (HEM.: TROPIDUCHIDAE), AT THREE CONSTANT TEMPERATURES

Pages

  31-44

Abstract

 Biology and DEMOGRAPHY of Ommatissus lybicus de Bergevin was studied under controlled conditions at 25±1, 30±1 and 35±1oC and 60±5% RH and 16: 8 L: D. Forty eggs of the pest (0-24h old) were used in each TEMPERATURE treatment. Developmental time was obtained 82.48±0.72, 75.79±0.55 and 89.85±0.71 days at 25, 30 and 35oC, respectively. Moreover, at 35oC, most of the biological activities of the DUBAS BUG were disrupted and individuals, especially females, incurred relatively high mortalities. Female life span was significantly higher at 25oC (108.21±1.33 days) comparing to that of the other TEMPERATUREs. The net reproductive rate (Ro) was 45.93 and 52.31 at 25 and 30oC; however, it extremely decreased at 35oC (5.82). The intrinsic rate of increase (rm) was 0.054, 0.062 and 0.029 at 25, 30 and 35oC, respectively. Similarly, doubling time (DT) was also close at-25 .and 30oC (14.2 vs 12.3 days) but it increased dramatically at 35oC (29.27 days). Based on life table parameters observed, it was concluded that 30oC could be an optimum TEMPERATURE for the biological activities of O. lybicus.
