That's codling moth, the worm in the apple. I have a decade-old backyard orchard and have built up a sustaining population of these buggers. Next year I'm going to get serious about hunting them down -- every one of them.
To this end, I put up a new Ambient WS2095 weather station and installed *weewx* on my Linux desktop, which does not run unattended. So far, so good. I see nominal, continuous temp stats being logged. My goal this winter is to learn to graph cumulative degree days, which I will use next summer to predict with uncanny accuracy (so they say) the very day that most C. pomonella larva are hatching. That is the day I will attack. Now it occurs to me this is not an unreasonable or unusual goal. I wonder if anyone else has done this and can show me how without my having to re-invent the wheel. I see hints in the *weewx* User's Guide that degree-day, degree_day, degreeday, and heating-day calculations are possible, but these don't seem to be implemented. I'm guessing they may be implemented in the *xstats* extension, but I'm not finding any such variable names there. (I may not be searching correctly or even searching in the right place.) Thanks for any suggestions. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
