Life-table analysis of the performance of Nilaparvata lugens (Hemiptera: Delphacidae) on two wild rice species
Journal of Economic Entomology 103 (5), 1628-1635
Abstract: Life tables of the planthopper Nilaparvata lugens (Stål) (Hemiptera: Delphacidae) on two wild rice species, Oryza officinalis Wall, ex Watt, and Oryza rufipogon Griff, and on 'Taichung Native 1' (O. sativa indica TN1) were studied at 27°C in the laboratory. The raw data were analyzed based on the age-stage, two-sex life table to take both sexes and the variable developmental rate among individuals and between sexes into consideration. The intrinsic rate of increase (r), the finite rate (lambda), the net reproduction rate (R₀) and the mean generation time (T) of N. lugens on O. officinalis were -0.0616 d^-1, 0.9402 d^-1, 0.10 offspring, and 36.7 d, respectively, showing that the species is resistant to N. lugens. The resistance of O. officinalis is expressed in the long developmental time from first to fifth instar of N. lugens, the reduced preadult survival rate, the short adult longevity, and low fecundity. However, the population parameters of the N. lugens on O. rufipogon and TN1 were 0.1096 d^-1, 1.1158 d^-1, 67.82 offspring, and 38.6 d and 0.1340 d^-1, 1.1434 d^-1, 144.77 offspring, and 37.2 d, respectively. These population parameters showed that N. lugens can successfully survive and reproduce on both O. rufipogon and TN1.
