Biological Differences

Amblyseius tamatavensis has been reported from over 20 countries around the world, and is also widely distributed in Brazil. It has been reported as potentially useful for the control of Bemisia tabaci, a pest/vector insect of great economic importance worldwide. Some studies have reported some biological differences among phytoseiid populations. The objective of this work was to compare 14 populations of different regions of Brazil (from the states of Alagoas, Goiás, Minas Gerais and São Paulo; straight line distance between northern and southern extremes of 2,560 km) in relation to the predation and oviposition potential when fed with eggs of B. tabaci biotype B. The morphological characterization of these mites showed that the population from Olhos d'Agua das Flores (Alagoas state) and a population from mixed origin maintained in the laboratory for about 5 years were constituted by mites with larger dorsal and ventrianal shield dimensions and presented the highest rates of daily predation (respectively 7.9 and 7.0 eggs/ female) and oviposition (1.2 and 1.1 eggs/ female). A positive and significant relationship was observed between mean population predation and oviposition rates. The results suggest that subsequent efforts should focus on exploring the variability of mites of these two populations in relation to predation and oviposition potential, in order to select a new, more promising population to control B . tabaci biotype B.

Scn Resistance

Soybean cyst nematode (SCN) is one of the most damaging pest of soybean. Discovery and characterization of the genes involved in SCN resistance are important in soybean breeding. Soluble NSF attachment protein (SNAP) genes are related to SCN resistance in soybean. SNAP genes include five gene families, and 2 haplotypes of exons 6 and 9 of SNAP18 are considered resistant to the SCN. In present study the haplotypes of GmSNAP18 were surveyed and chacterized in a total of 60 diverse soybean genotypes including Korean cultivars, landraces, and wild-types. The target region of exons 6 and 9 in GmSNAP18 region was amplified and sequenced to examine nucleotide variation. Characterization of 5 haplotypes identified in present study for the GmSNAP18 gene revealed two haplotypes as resistant, 1 as susceptible and two as novel. A total of twelve genotypes showed resistant haplotypes, and 45 cultivars were found susceptible. Interestingly, the two novel haplotypes were present in 3 soybean lines. The information provided here about the haplotypic variation of GmSNAP18 gene can be further explored for soybean breeding to develop resistant varieties.
