摘要

The Asian citrus psyllid D. citri is regarded as one of the most important pest of citrus, because it is known to be the most efficient vector of bacterium Liberobacter asiaticum that cause citrus greening or huanglongbing. Survivorship from egg to adult emergence and fertility of D. citri on C. suhuiensis (limau madu) were studied under laboratory condition (29+or-1 degrees C and 85% RH). Limau madu of height 12 cm with flush leaves were placed in a wooden cage covered with nylon mesh containing citrus plant with D. citri for egg laying. Life table was constructed base on population parameters obtained under unlimited food supply and natural enemies free environment. The result showed that highest mortality in 1st instar nymphs (40.23%) with k-value of 0.22 and mortality (25.59%) in 2nd instar nymphs with k-value of 0.13 are the key factors regulating the population size. The sex ratio (proportion of female to male) was 1:0.65. The maximum life span of female was 23.6 days and the trend of oviposition showed a peak at about the 12th day of the female life span with 3.85 mean numbers of eggs per female. The intrinsic rate of natural increase (rm) was 0.026 per female per day and daily finite rate of increase ( lambda ) was 1.023 per female per day, with a mean generation time (T) of 26.528 days. The net reproductive rate (Ro) of the population was 2.004 and the population Doubling Time (DT) was within 26.456 days. Besides that, the life table showed that, the population of D. citri in the present study display type 3 type of survivorship with about 25.971% of the eggs successfully reached adult stage. Above findings on life table and demographic parameters of D. citri particularly its capacity for natural increase and mortality rate of the different developmental stages are necessary for development of reliable and sustainable IPM strategy for the pest.
