SUMMARY:

Numerous species of palm trees are plants of great economic value, being among the main sources of non-timber forest resources, with several uses and generating employment and income for several farmers. The incidence of pests in palm trees is a limiting factor for exploration, accounting significantly for the general depletion of the crop and also for the reduction in productivity.This situation is aggravated by the occurrence of pests such as Rhynchophorus palmarum L. (Coleoptera: Curculionidae) and Metamasius hemipterus L. (1764) (Coleoptera: Curculionidae), the damage to the crop is caused by the larvae that make galleries in the apical meristem of the palm trees, causing the reduced tillering and opening of holes can serve as a gateway for phytopathogens, in addition they can also be vectors of diseases that can lead to plant death. Semiochemicals can alter the behavior of insects, thus allowing the development of sustainable pest control strategies. To date, there is no information in the literature or in the Ministério da Agricultura, Pecuária e Abastecimento (MAPA) on a potentially efficient insecticide for the management of R. palmarum and M. hemipterus. Currently, control with the use of traps with attractants has been the most efficient form of control to reduce the populations of these insect pests. Therefore, the objective of this work was to analyze the efficiency of synthetic pheromones and kairomones in alphatometry and electroantenography tests on the attractiveness of R.palmarum and M.hemipterus as a measure of behavioral control. The work was carried out in the Laboratório de Pesquisas em Recursos Naturais (LPqRN)from the Institute of Chemistry and Biotechnology of the Universidade Federal de Alagoas – Campus A.C. Simões. It was concluded that males and females of R.palmarum present electroantenographic responses to the compound acetoin, being more attractive in males than females. Males and females of R.palmarum and M. hemipterus showed a better response to the Meta 1 compound, when compared to the compounds, Meta 2, Rincophorol and Coconut oil.
