Insects are a main source of food loss. Climate change can alter insect damage in at least two ways: increases in reproductive rate from temperature increases and changes in pheromone effectiveness . Increasing temperature up to about 40°C raises the rates of insect food digestion and reproduction , but temperatures above that level are fatal for many insects . Most insects rely on pheromones to facilitate reproduction. Higher temperatures, but also increases in atmospheric CO2 and 03 levels, can affect this process. Insect species that rely on long-range chemical signals  will be most impacted, because these signals suffer from longer exposure to processes that reduce pheromone effectiveness (Medina
