Resumo: |
The raw material that integrales biodiesel production chain can be obtained from different oli (vegetable oil), and among the crops for such applicability, highlights the phisic nut - culture that has been scattered by their agronomic and production. Several arthropod pests have been found associated with this crop in Brazil, and come undermining the productive success of this culture, including the mites Tetranychus bastosi. Therefore, the aim of this study was to survey and distribution of mites associated with bouts of Jatropha curcas germplasm bank in the semi-arid Pernambuco and evaluate the influence of these accesses on biological parameters, population growth and reproductive success of the mite T. bastosi (Acari: Tetranychidae). There was no difference among the accessions for the stages of development and other parameters of the biological cycle. However, regarding the life table parameters, except for the net reproductive rate (Ro) and mean generation time in days (T), all the others differed among accessions. The intrinsic rate of increase (rm), finite rate of increase (λ) were smaller hits 4 and 17 and greater access 11. The time needed to double the initial population (Td) were greater access to 04, values that differ from the access 11. With the instantaneous rate of population growth (ri), followed by access 04 accessions 17 and 18, showed the lowest growth of the population. Thus, it has the accesses 4 and 17 as the least favorable to the development, growth and reproductive success of the population of T. bastosi and the 11 access more susceptible. Therefore, it reinforces the importance of understanding the characteristics of these host plants (accesses) and how they act on these pest mites, aiming the development of control strategies. |
