Abstract-Infochemicals play an important role in the biology of many insect species. An understanding of their role in plant-herbivore-carnivore interactions can be used in the development of tools for the enhancement of environmentally benign alternatives to synthetic pesticides. This review discusses how chemical information mediates ecological interactions between organisms and the role of infochemicals in integrated pest management. Infochemicals can be used in pest monitoring and in pest control, through mating disruption, mass trapping and to aggregate herbivores at delivery sites for biological control agents. Particular emphasis is placed on the potential of using pheromones and kairomones in the management of the banana weevil, Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae), a pest in plantations of East African highland banana and plantain in most banana-growing regions of the world. Cosmopolites sordidus produces an aggregation pheromone that attracts both males and females. This pheromone has been identified and synthesised and is being recommended as an effective agent in the trapping and control of the weevil. The synergism between banana plant extracts (kairomones) and the synthetic pheromone in attracting C. sordidus should be better exploited. Future research areas that can provide information for the development of an infochemical-based trapping system for the management of C. sordidus are discussed.Key Words: infochemicals, kairomones, aggregation pheromone, Coleoptera, banana weevil, Cosmopolites sordidus, biological control, pathogenic fungi, predators, synergism Résumé-Les sémiochimiques jouent un rôle important dans la biologie de beaucoup d'espèces d'insectes.

Cet article montre comment l'information chimique agit sur les interactions écologiques entre organismes et, discute du rôle des infochimiques dans la gestion intégrée des ravageurs. Les sémiochimiques peuvent être utilisés pour surveiller et contrôler les ravageurs, à l'aide de la technique de la confusion sexuelle et du piégeage de masse et pour rassembler les ravageurs en un lieu donné pour les agents de lutte biologique. Une attention particulière a été portée au rôle potentiel de l'utilisation des phéromones et des kairomones dans la gestion du charançon du bananier Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae), un ravageur 242 W.

“…In Uganda, distribution studies showed that over 60% of the adult weevils in the banana field were associated with crop residues such as rotting pseudostem (Gold et al, 2004). The weevil has predators that have been mostly found in environments harboring weevils such as banana pseudostem traps and fermenting banana pseudostem tissue, often in larval weevil tunnels (Koppenhofer et al, 1992;Koppenhofer, 1993;Tinzaara et al, 1999;Abera, 2004). Some ant species that have the potential to control C. sordidus include Pheidole megacephala and Tetramorium guineese (Mayr) (Hymenoptera: Formicidae) (Gold et al, 2001;Abera, 2004).…”

Nonant predators known to prey on weevil eggs and larvae include Dactylosternum abdominale (Fabricius) (Coleoptera: Hydrophilidae), Euborellia annulipes (Lucas) (Dermaptera: Carcinophoridae), and Thyreocephalus interocularis (Eppelscheim) (Coleoptera: Staphylinidae) (Koppenhofer et al, 1992). Of these five predator species, D. abdominale and P. megacephala are the most abundant predators in environments preferred by weevils in Uganda (Tinzaara et al, 1999;Gold et al, 2001;Abera, 2004).…”

Olfactory Responses of Banana Weevil Predators to Volatiles from Banana Pseudostem Tissue and Synthetic Pheromone

Abstract-As a response to attack by herbivores, plants can emit a variety of volatile substances that attract natural enemies of these insect pests. Predators of the banana weevil, Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae) such as Dactylosternum abdominale (Coleoptera: Hydrophilidae) and Pheidole megacephala (Hymenoptera: Formicidae), are normally found in association with weevil-infested rotten pseudostems and harvested stumps. We investigated whether these predators are attracted to such environments in response to volatiles produced by the host plant, by the weevil, or by the weevilYplant complex. We evaluated predator responses towards volatiles from banana pseudostem tissue (synomones) and the synthetic banana weevil aggregation pheromone Cosmolure+ in a two-choice olfactometer. The beetle D. abdominale was attracted to fermenting banana pseudostem tissue and Cosmolure+, whereas the ant P. megacephala was attracted only to fermented pseudostem tissue. Both predators were attracted to banana pseudostem tissue that had been damaged by weevil larvae irrespective of weevil presence. Adding pheromone did not enhance predator response to volatiles from pseudostem tissue fed on by weevils. The numbers of both predators recovered with pseudostem traps in the field from banana mats with a pheromone trap were similar to those in pseudostem traps at different distance ranges from the pheromone. Our study shows that the generalist predators D.
