Table 5 Logistic models estimated for each grapevine cultivar and for all cultivars in a joint model

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

  1. The models relate the proportion of cumulative catches in pheromone traps to the accumulated degree-days in each year using the lower-temperature thresholds (LTT) 1determined by Avidov and Gothilf (1960) 2determined by Ringenberg et al. (2005), LL, confidence lower limit, UL, confidence upper limit a and b parameters estimated for the logistic models, logit p ^ = a + b · DDp = e a + b . DD 1 + e a + b . DD .
  2. †: Same letter indicates non-significant differences between b values (p ≤ 0.05) for the different grapevine cultivars.
