“…Oehlschlager (2005) reports that a trapping rate of one pheromone lure per 2 ha reduced oil palm damage by more than 90%, while being less expensive and more effective than chemical control practices. In other cases, however, trapping may not be sufficient to control O. rhinoceros population (Moore, 2011) and an assessment of the efficiency and cost of the trapping method in immature plantations compared to a conventional chemical control is still needed.…”

-Palm oil is nowadays the first vegetable oil consumed worldwide. Given the world population growth and the increasing demand in fat for food and fuel, the increase in oil palm production is expected to continue. It is thus important to find ways of reducing the ecological impact of oil palm plantations at both the agroecosystem and the mill supply area levels, by improving agricultural practices and land uses. This is where agroecology can play a very critical role. The present article gathers short stories on agroecological practices currently taking place in oil palm plantations in South-East Asia. Such stories notably highlight the importance of the various palm co-products and how appropriate recycling strategies can allow for reducing external inputs to both the field and the mill. Besides limiting environmental impacts thanks to such savings, several coproducts used as organic amendments can even help to maintain or enhance soil quality. Other stories explored agroecological practices developed for biological controls. Although integrated pest management has been applied in palm plantations for a long time, the underlying mechanisms are still not fully deciphered and practices still need to be improved. More knowledge is needed in order to better account for the holistic role of biodiversity and arbitrate trade-offs between practices and ecosystem services, at both plantation and landscape levels.Keywords: palm oil / agroecology / biological control / recycling / composting / soil quality Résumé -Pratiques agroécologiques en plantations de palmier à huile : exemples de terrain. L'huile de palme est aujourd'hui la première huile végétale consommée au monde. Étant donné la croissance démographique mondiale et la demande accrue en corps gras pour l'alimentation et les biocarburants, l'augmentation de la production d'huile de palme devrait perdurer. Il est ainsi primordial de trouver des moyens de production permettant de réduire l'impact écologique des plantations de palmier à huile, à la fois à l'échelle de l'agroécosystème et celle du bassin d'approvisionnement de l'huilerie, en améliorant les pratiques et la gestion des usages des sols. Les principes de l'agroécologie peuvent aider à développer des solutions à ces diverses échelles. Cet article rassemble diverses histoires courtes illustrant des pratiques agroécologiques mises en place dans des plantations de palmier à huile en Asie du Sud-Est. Ces illustrations mettent en évidence l'importance des nombreux co-produits issus du palmier et leur rôle clé dans les stratégies de recyclage pour réduire le recours aux intrants externes pour la plantation comme pour l'huilerie. Au-delà de la réduction des impacts environnementaux du fait de ces économies d'intrants, certains co-produits restitués en plantation peuvent également permettre de maintenir, voire d'améliorer, la qualité des sols. D'autres histoires courtes parcourent quelques autres pratiques agroécologiques dans le domaine de la lutte intégrée. Bien que de nombreuses pratiques de contrôle bi...

“…Several studies have highlighted the importance of food baits to sustain RPW pheromone trap catches (Faleiro and Chellapan, 1999;Hallett et al, 1999;Nair et al, 2000;Faleiro and Satarkar, 2003;Oehlschlager, 2007). The food baits used in Saudi Arabia are predominantly date fruits (fodder grade) with some growers also using date palm and sugarcane stem pieces.…”

The red palm weevil, Rhynchophorus ferrugineus Olivier is a major pest of date palm. The pheromone-based mass trapping of weevils has traditionally been an important component of integrated pest management program for this pest. In order to maximize the trap catches, six field experiments were conducted in the present study including evaluation of stump trap, lures, lure synergist ethyl acetate, kairomones, food baits and yeast. The stump trap lured more weevils than the tree trap. The three tested pheromone lures were similar in attraction but with ethyl acetate, Ferrolure+™ lured more weevils than RHYFER™. Amongst the tested kairomones, acetic acid and ethyl acetate alone and together emerged as strong synergists to lure. The date fruits, date palm stem pieces and sugarcane pieces attracted similar number of weevils but in presence of ethyl acetate, date fruits attracted significantly more adults. Date fruits attracted more weevils with yeast than alone but overall, date fruits, yeast and ethyl acetate together recorded the highest trap catches. The differences in attraction of weevils due to various treatments have been analyzed and results are discussed.

“…Strategies based on behaviour‐modifying semiochemicals are well known in pest management. Today, aggregation pheromone traps, supplemented with palm esters and/or fermenting mixtures of plant tissues and/or molasses, are used in various countries for the monitoring and mass trapping of RPW adults in both agricultural and urban environments . Nevertheless, semiochemical‐based RPW control could be improved by the combined use of different stimuli that would not only attract the insects into the traps but also protect the palms via a push‐pull method.…”
