Global atmospheric carbon dioxide (CO2) concentration has increased by 40 % since the pre- Industrial Revolution, predominantly as a result of increased fossil fuel emissions and deforestation. Carbon dioxide will alter temperature, rainfall and weather patterns, which will directly and indirectly affect crops, yield, food quality and overall, worldwide food security. It will also impact environment, pests and diseases through changes in plant growth, physiology and biochemical properties, among others. Increased CO2 levels alter the chemical composition of the plant by affecting its nutritional quality, which modifies feeding behaviour and biology of herbivorous insects. This in turn is thought to effect higher trophic levels, potentially impacting the biological control of agricultural pests. To test the extent of changes mediated by elevated CO2 (eCO2 = 700ppm) on plant, aphid and parasitoid interactions, we studied the phytophagous aphid pest Aphis gossypii Glover (Hemiptera: Aphididae) and its natural enemy, the parasitic wasp Aphidius colemani Viereck (Hymenoptera: Braconidae), developed on melon plant Cucumis melo Linnaeus (Cucurbitaceae). In the plant growth chambers, aphid development and fecundity were assessed under two CO2 levels as well as the parasitoid performance. This study aims to describe future interactions between an economically important pest and its natural enemy, which is currently used as an effective biological control option in Integrated Pest Management programs.
