Abstract
- Development duration, sex ratio, reproduction, survival, and the principal life parameters of Raoiella indica Hirst on Cocos nucifera were determined. The study was carried out under laboratory conditions at 30.8 ± 1.5 °C and 56.7 ± 8.2% RH. The average duration of each lifehistory stage was: egg 4.64±1.03 days; larva 5.12±1.01 days; protonymph 3.34±1.03 days; and deutonymph 4.27±1.3 days. The total period from egg deposition to adulthood averaged 17.38±2.65 days. Preoviposition and oviposition periods averaged 2.93±0.86 and 12.77±6.34 days, respectively, and average oviposition was 10.64±3.46 eggs per female. Female mean longevity was 19.09±8.32 days. Sex ratio was 67% of females. The average number of eggs laid per females per day increased from the beginning of oviposition to the 14 days. The main parameters associated with a fertility life table were as follows: net reproductive rate (R0 =14.03), intrinsic rate of increase (rm =0.41), finite rate of increase (λ=1.51), mean generation time (t=12.36), and the doubling time (TD=1.69).The life table parameters obtained confirmed that R. indica had a high reproductive potential on coconut palm, characteristic of exotic invasive species.
