From: Relationship between male moths of Cryptoblabes gnidiella (Millière) (Lepidoptera: Pyralidae) caught in sex pheromone traps and cumulative degree-days in vineyards in southern Uruguay

Figure 2

Relationship between degree-days and the cumulative proportion of adult males of Cryptoblabes gnidiella caught in pheromone traps on each of four grapevine cultivars between 1 st December and 31 st May in 4 years and at two sites in Uruguay. A) Employs the lower-temperature threshold determined by Avidov and Gothilf (1960); B) uses the lower-temperature threshold estimated by Ringenberg et al. (2005). Observed values are grey, estimated values are black, and estimated proportions at the end of the first generation are identified with an arrow.
