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.
