  Using Synthetic Pheromone and Degree-Days to Determine the Bio-Fix of the Grapevine Mealybug Planococcus ficus (Sig.) (Hemiptera: Pseudococcidae )
  Author(s): K. A. Achiano*
  
  Four vineyards in South Africa, two from the Coastal region and two inland, with mealybug infestation, were chosen for studies to determine a bio-fix for the vine mealybug Planococcus ficus (Sig.). Male mealybug numbers were monitored using delta traps baited with sex pheromone lures in each treatment plot. Old sticky pads and lures were removed and replaced with new ones every week in Spring and Summer and four weeks in Autumn and Winter, respectively. This was done for three seasons (2005, 2006 and 2007), from June to October. However, to determine the bio-fix, the males were counted every week from 08-08-2007 to 26-08-2007. The cumulative degree days (°D) obtained were lowest at Farm D farm and also the mealybugs had only three generations as compared to five on the other three farms. The males had higher cumulative numbers than the females throughout the census and th.. View More»
