| Description
| - Aphid populations show periodic fluctuations and many causes are attributed to their dynamic. We investigated theregulation by temperature of the aphid populations composed of Metopolophium dirhodum, Sitobion avenae, andRhopalosiphum padi on winter wheat using a 24 years long time series data. We computed the sum of daily temperaturesabove 5uC, the threshold temperature for aphid development, and the sum of daily temperatures within the [0(threshold forwheat development),5] uC interval. Applying Generalised Additive Model framework we tested influences of temperaturehistory expressed via degree days before the start of the aphid immigration on the length of their occurrence. We aimed toestimate the magnitude and direction of this influence, and how far to the past before the start of the aphid season thetemperature effect goes and then identify processes responsible for the effect. We fitted four models that differed in theway of correcting for abundance in the previous year and in specification of temperature effects. Abundance in the previousyear did not affect the length of period of aphid population growth on wheat. The temperature effect on the period lengthincreased up to 123 days before the start of the current season, i.e. when wheat completed vernalization. Increased sum ofdaily temperatures above 5uC and the sum of daily temperatures within the [0,5] uC interval both shortened the length ofperiod of aphid population growth. Stronger effect of the latter suggests that wheat can escape from aphid attacks if duringwinter temperatures range from 0 to 5uC. The temperature influence was not homogeneous in time. The strongest effect ofpast temperature was about 50 to 80 and 90 to 110 days before the beginning of the current aphid season indicatingimportant role of termination of aphid egg dormancy and egg hatching
