Conteúdo: | The rice stalk stink bug,Tibraca limbativentrisStål, is an important rice pest in Brazil, causing significant damage to riceplants and consequently yield losses, with a high invasive potential in Mexico and USA. The male-produced sex phero-mone of this species was recently identified as a 7:3 mixture of (3S,6S,7R)-1,10-bisaboladien-3-ol (1)and(3R,6S,7R)-1,10-bisaboladien-3-ol (5) (a.k.a. zingiberenols). The aim of this study was to evaluate field responses ofT. limbativentrisfemales to the racemic mixture and stereoisomers of 1,10-bisaboladien-3-ol, including the male-produced sex pheromone.The results obtained in two rice-producing areas of Brazil (Rio Grande do Sul and Santa Catarina) showed that traps baitedwith the main component1alone, the racemic mixture, and a mixture of1and5were attractive to females ofT. limbativentris. The minor component5was unable to attract females when used alone. The results indicate that thesex pheromone ofT. limbativentrisand racemic mixture of 1,10-bisaboladien-3-ol were equally attractive to co-specificfemales in rice fields, and they could be a tool to incorporate in rice stalk stink bug management programs.
