“…The potential of using banana kairomones, especially fermented tissues, as synergists to synthetic pheromones has not been well exploited, although there is information indicating that banana plant volatiles could be used to enhance the attractiveness of synthetic pheromones (Ndiege, 1996;Jayaraman et al, 1997). Further research is needed on host plant odours to optimise the use of kairomones in an infochemicalbased trapping system for C. sordidus control.…”

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.

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.

“…The absolute stereochemistry of the natural sordidin ((1S,3R,5R,7S)-(+)-1-ethyl-3,5,7-trimethyl-2,8-diosabicyclo[3.2.1]octane) was subsequently determined (Mori et al 1996;Fletcher et al 1997). Ndiege et al (1996) and Jayaraman et al (1997) developed a large-scale synthesis of racemic sordidin that made field-testing possible. Its attractiveness to both males and females confirmed its function as an aggregation pheromone, and it was formulated at ChemTica International in Costa Rica as cosmolure + pheromone (Tinzaara et al 2003).…”

Abstract:The banana root borer Cosmopolites sordidus (Coleoptera: Curculionidae) is native to Malaysia and Indonesia but is found in nearly all banana-growing areas of the world. Studies were conducted to determine the pheromone trap efficacy, effect of shade on trap catches and to monitor the population of C. sordidus using pheromones in Guam. In Guam, pheromone traps were used to monitor the population level of C. sordidus. Before monitoring began, two basic studies were carried out, which established that pheromone-baited ramp traps positioned in the shade of the banana crop canopy caught significantly more adults than those placed in sunlight and that ramp traps baited with pheromone lures caught significantly more adults than did identical traps without pheromone lures. Ramp traps baited with pheromone lures were set up at each of 10 locations throughout the island in November 2005. Weekly counts were made of the borers caught by the pheromone traps.The data indicated higher population levels (>10 per week) in the northern region and low (<5 per week) to medium level (5-10 week) populations in the southern part of the island. These differences among sites were highly significant. Linear and quadratic effects of rainfall on the number of borers captured were statistically significant, but according to quadratic regression models, the significance was due to differences at just one site.

“…In 1995, a male produced aggregation pheromone (sordidin) was identified for C. sordidus (Beauhaire et al, 1995), and a large scale synthesis allowed evaluation of sordidin in the field (Ndege et al, 1995;Jayaraman et al, 1997). Baiting pseudostem traps with sordidin released at one milligram per day increased capture rates by eight fold, while white pitfall traps containing soapy water and from which sordidin was released at one milligram per day captured about two and a half times more C. sordidus than similarly sordidin-baited pseudostem traps (Jayaraman et al, 1997).…”

Management of Cosmopolites sordidus and Metamasius hemipterus in Banana by Pheromone-Based Mass Trapping

Mass trapping Cosmopolites sordidus (Coleoptera, Curculionidae) using a pheromone-baited pitfall trap and Metamasius hemipterus (Coleoptera, Curculionidae) using a pheromone-sugarcane-baited open gallon trap was conducted in commercial banana. Four traps for each insect per hectare were placed in each of two 5-hectare plots of banana. Two additional 5-hectare plots were designated as controls and treated according to the plantation protocol. Capture rates of C. sordidus and M. hemipterus declined by >75 % over 10-12 months. In the banana growing region studied, corm damage was due primarily to C. sordidus, while only a minor amount of damage was attributable to M. hemipterus. Corm damage reduction in trapping plots was, thus, attributed primarily to C. sordidus trapping. In trapping plots, corm damage decreased by 61-64 % during the experiment. Banana bunch weights increased 23 % relative to control plots after 11-12 months of trapping. Fruit diameter did not vary between bunches harvested from trapping plots vs. control plots. Plant vigor, however, as determined by stem circumference at one meter above ground increased in plots with traps compared to control plots. Trapping for C. sordidus in two plantations of over 200 hectares each, reduced corm damage 62-86 % relative to pre-trapping levels. Insecticide control measures in place when the experiment commenced resulted in about 20-30 % corm damage, while use of pheromone trapping to manage C. sordidus lowered corm damage to 10 % or less. It is estimated that the increase in value of increased yield obtained in this trial (23 %) is about $4,240 USD per year per hectare, while the cost of pheromone trapping is approximately $185 USD per year per hectare. The trapping program becomes revenue neutral if bunch weights increase by an average of 1 % per year of trapping. Approximately 10 % of all plantation area in Costa Rica use the pheromone trapping system described here. The system also is used in Martinique, Guadeloupe, and the Canary Islands.
