Holistic management of pollinators and pests: Integrating semiochemicals with on-farm pesticides
Annals of the Entomological Society of America 115 (1), 56-68
Abstract: Insect pollinators and insect herbivores affect plant reproduction and fitness. Floral displays are used to attract and manipulate pollinators' behavior to support plant sexual reproduction while rewarding the visitors with access to nectar and pollen. The plant–pollinator interactions use various semiochemicals as important communication channels for successful species interaction networks. Floral display and scents can also attract insect herbivores (in which case they act as kairomones). Consequently, semiochemical-color-based traps used for monitoring pest insects in crop fields often accidentally capture pollinators, and these interactions simultaneously affect pest monitoring, pollinator assemblages, and crop production in agroecosystems. An integrated interdisciplinary approach that would use inter- and intraspecific signals employed by foraging insects for predator's avoidance with the goal of deterring pollinators and beneficial insects from entering pesticide-treated fields is proposed. Specifically, it should be possible to reduce the bycatch of pollinators by pest monitoring traps if these trap lures also include the alarm pheromones of insect pollinators such as bees. In addition, other tactics for pollinator protection could include first the application of nonlethal repellants to fields that have recently been treated with synthetic chemical pesticides to deter pollinators' visitation. A second action would be to incorporate the results of comparative risk evaluations (pollinators vs pests) for botanical pesticides, as well as for synthetic pesticides. Finally, we urge that wild pollinator species be included in pesticide risk assessments, especially for new classes of insecticides. Collectively, these actions should integrate pest and pollinator management strategies.
