Cereal aphid numbers caught in suction traps are an indication of flights and do not replace the need for direct searching and monitoring in your crop.
Relatively high numbers of aphids are expected till the end of May, with spring flights occurring late September or October
Generally the warmer the temperature, the faster an aphid will develop into an adult. However other factors, such as amount of rain, can affect aphid development and survival.
