ABSTRACT.
A phylogeographic analysis inferred from the partial mitochondrial cytochrome oxidase subunit I gene (433 bp) was performed with 22 populations of Diaphorina citri Kuwayama collected in the Americas and one in the Pacific. Eight populations from four countries in South America, 14 from four countries in North America, and one from Hawaii were analyzed. Twenty-three haplotypes (hp) were identified and they fell into two groups: hp1-8 were identified in South America (group 1) and hp9-23 were identified in North America and Hawaii (group 2). Hp1 and nine were present in the highest frequencies within each population and within their group, 81 and 85% for group 1 and group 2, respectively. A diagnostic nucleotide at position 48 was identified that allowed for the discrimination of the two groups; in addition, no haplotypes were shared between the two groups. An analysis of molecular variance uncovered significant genetic structure (Φ CT = 0.733; P < 0.001) between the two groups of the Americas. Two haplotype networks (ParsimonySplits and Statistical Parsimony) discriminated the two groups and both networks identified hp1 and nine as the predicted ancestral or founding haplotypes within their respective group. The data suggest that two separate introductions or founding events of D. citri occurred in the Americas, one in South America and one in North America. Furthermore, North America and Hawaii appear to share a similar source of invasion. These data may be important to the development of biological control programs against D. citri in the Americas.

ABSTRACT.
During 1997 and 1998 the effect of complementary water supply at different growing stages on production and storage ability was studied. Granex 33 cultivar was transplanted in beds 1.5 m appart with four rows (280000 plants/ha). Small rain out shelters were used, (2x3 m), to cover each plot in different periods . Treatments were: 1. covered ali the growing season and non irrigation in 1997 and non irrigation without cover in 1998; 2. covered from, bulbing to harvest; 3. covered up to bulbing and 4. rainfall plus irrigation.
Treatment 2, 3 and 4 was similar in 1997 and 1998. When the tensiometers reached -0.25 bar at 20 cm depth. Treatments were arranged in a randomized block design with four replications. Irrigation was applied with drippers at 0.50 m appart anda flow rate of 1.75 l/h. Tensiometers and steel rods were installed at 20 cm depth in each plot to measure soil water content. TDR measurements were collected twice a week. Significant difference in total and marketable yield were obtained both years. Total yield was 51 ton/ha in 1997 and 66.7 ton/ha in 1998, respectively. There were not significant differences in total and marketable yield between treatment 2 and 3 in 1997 and 1998. Non irrigation and treatment 2 showed better storage ability as compared with treatment 3 and 4 in 1997. |
