Palpita forficifera Munroe, 1959 (Lepidoptera: Crambidae) is the main pest of the olive tree (Olea europaea L., Oleaceae) in Brazil. We observed the stink bug Podisus nigrispinus (Dallas, 1851) (Hemiptera: Pentatomidae) predating larvae of P. forficifera in olive orchards. Therefore, the aim of this study was to register the occurrence of this predator in olive orchards as well as verify the predation of nymphs of P. nigrispinus when offered different numbers of P. forficifera larvae. In laboratory bioassays, it was verified that duration (days) of insects of 4th and 5th instars of P. nigripinus was prolonged when fewer larvae were offered (Dietary regime 1). The average consumtion of 3rd instar larvae of P. forficifera per instar of P. nigrispinus was superior for the dietary regime 2, where there was a greater availability of preys, resulting in a higher total consumption of larvae of P. forficifera over time. In addition, in the availability of larger quantities of P. forficifera larvae, adults of P. nigrispinus showed a higher weight gain. The sex ratio was not affected by dieraty contition. This study reports the first occurrence of nymphs and adults of P. nigrispinus predating larvae of P. forficifera in field, and shows the predation potential of P. nigrispinus in larvae of P. forficifera, demonstrating the importance of preserving this natural enemy in olive orchards. |

Genetic diversity is the one of the most important issues in conservation studies of livestock breeds or endangered species. In the present study, we tested the feasibility of describing the recent evolution in genetic diversity through genome-wide SNP genotyping and estimates of linkage disequilibrium decay patterns, effective population size, inbreeding coefficient based on runs of homozygosity and population structure. We choose the bovine indicine breed Guzerá because it has suffered recent bottlenecks which have been registered historically. A sample of 1036 females was genotyped using Illumina BovineSNP50. A resampling strategy was applied to correct for sampling biases caused by the population structure in herds, and by the extensive use of some sires for artificial reproduction. A subsample of 210 animals and 32,806 markers with MAF > 0.01 was used. Very low linkage disequilibrium was detected for distances greater than 120 Kb between two markers. Furthermore, three points of decrease in effective population size between generations were detected, which coincide with the historically registered bottlenecks. The inbreeding coefficient, based on runs of homozygosity, confirmed a strong contribution of the last 20?30 generations to current inbreeding. In the population structure analysis, the most probable number of sub-populations is 2, reflecting selection purpose (beef or dual-purpose). Taken together, these results allow a retelling of the recent evolution of this breed. The strategy described here will be useful for other breeds or even species for which a careful historical registry is not available for conservation proposals.
