Résumé : Le Limacodidae Setothosea asigna est capable d'entrainer des pertes de productions très importantes dans les plantations de palmiers à huile indonésiennes. Un système très simple de piégeage de ces animaux a été mis en place avec des phéromones sexuelles comme appât, afin de surveiller leur population et de prévoir des attaques massives

Résumé (autre langue) : Sex pheromone traps have been tested over a period of two years for monitoring the populations of the limacodid Setothosea asigna in oil palm plantations at Marihat, Indonesian Oil Palm Research Institute. For the implementation of this new surveillance method the pheromonal secretion components of the virgin female were identified previously at the Laboratory of Chemical Mediators, INRA, France. The synthetic blends were placed in rubber dispensers. A very simple and cheap trap design was used consisting of empty mineral water plastic bottles with four openings at the top. The pheromone dispenser was suspended inside and the bottom of the bottle contained teepol with water to retain the adults. In order to deploy this trapping method different experiments were carried out to determine the height of the traps according to the age the plantation, the distance between the traps and the density necessary per hectare. The results of the catches showed that only males of Setothosea were caught. Males were attracted to the traps during only a short period at the beginning of the night. The importance of the catches compared with classic monitoring by cutting one frond per hectare proves that more accurate data can be obtained with the pheromone. One pheromone capsule can last for two months. To be used as an indicator of population one capsule per twenty hectares is enough. Monitoring of data during a yearly period demonstrated that the population of Setothosea at endemic level or reaching an outbreak situation can be detected in advance. Early warning systems using the sexual trapping technique with pheromone which is easy to implement, may allow for a cheaper replacement of the conventional method of census without damaging the palms. It also allows the detection of the level of Setothosea population in the very beginning thus preventing large outbreaks of this pest.
