Answer
Hi Gabriel,

What I would do with your plants right now is drop your photoperiod down to the equivalent of here on the mainland.  This site will be helpful:  http://www.sunrisesunset.com/calendar.asp?comb_city_info=Wilmington%252C%2520Nor  It will be more effective if you do it somewhat gradually over the month until you get it to what you see on this page.  If it's possible to keep the plants cooler that will help.  Once you have the plants at that 9-10 hour day, it would be helpful if you put the flytrap and Darlingtonia in the refrigerator at night.  That would probably be enough, and it is similar enough to what would happen in nature.  The S. purpurea should be fine without doing that.  Clip off leaves that brown up, which should happen with the shorter days.

I don't have as much direct experience with inducing the dormancy period in the tropics, but we've talked to friends in Hawaii, and they say Sarracenia do fine since Hawaii does experience a change in daylight hours.  Venus flytraps slow down and die if they don't get a dormancy, and I don't know anyone there that has tried Darlingtonia.  They're hard enough to keep alive here.  Here's a resource that should be helpful.  http://pitcherplants.proboards.com/

Good Growing!
