A Systems Approach to Pest Control Research
WHY SYSTEMS ANALYSIS of objects and any object can be described by listing its attributes." Systems analysis would be a useful tool for certain kinds of pesticide research, particularly that involving Within any system, many subsystems exist. All decisions affecting the environment or the ecosystem. systems are subsystems of the next higher one. This is A well-designed systems analysis would pe...
متن کاملForest bolsters bird abundance, pest control and coffee yield.
Efforts to maximise crop yields are fuelling agricultural intensification, exacerbating the biodiversity crisis. Low-intensity agricultural practices, however, may not sacrifice yields if they support biodiversity-driven ecosystem services. We quantified the value native predators provide to farmers by consuming coffee's most damaging insect pest, the coffee berry borer beetle (Hypothenemus ham...
متن کاملEffects of land use on bird populations and pest control services on coffee farms.
Global increases in both agriculture and biodiversity awareness raise a key question: Should cropland and biodiversity habitat be separated, or integrated in mixed land uses? Ecosystem services by wildlife make this question more complex. For example, birds benefit agriculture by preying on pest insects, but other habitat is needed to maintain the birds. Resulting land use questions include wha...
متن کاملEvaluation of cocoa- and coffee-derived methylxanthines as toxicants for the control of pest coyotes.
Methylxanthines were quantified in coffee, tea, and chocolate products. Tarajuilie tea from India, cocoa powder, and cocoa nibs contained the highest levels of methylxanthines. Theobromine, caffeine, and theophylline combined in the ratios observed in tea and chocolate were ingested by coyotes. Although both mixtures induced acute toxicity, the symptoms accompanying the chocolate methylxanthine...
متن کاملExotic pest insects: another perspective on coffee and conservation
Research on crop systems and biodiversity conservation in the tropics has mainly been concerned with how low to mid intensity agricultural systems can benefit from adjacent natural habitats by receiving ecosystem services from natural biodiversity. One intensively studied crop in this framework is coffee. Positive effects are relatively easy to quantify by comparing coffee yield and by recordin...
