NPR/NGS RADIO EXPEDITIONS Show: Fly¿s Ear Log of DAT #: 2 Date: 6/3/99 ng = not good ok = okay g = good vg = very good :49 sound begins 3:00 ¿11:00 silence 11:52 technical tinkering 12:28 cricket sounds begin RH 13:37 Would you like me to, sort of, come in here and open up some of these barrels for you? AC 12:44 Well, just tell me about this room. You¿ve got barrels and barrels of crickets in here, RH 13:55 Yes, well this, actually, I¿ve been working on crickets for a long time and this room is, is heated and humidified to be like a tropical rain forest so the humidity should be running 80 percent or better and we keep the temperature at about, it¿s a little cool today, but we try to keep it around 86 degrees. And we give them 14 hours of daylight and 10 hours of dark. This is probably the largest colony of crickets for scientific use in the world. We maintain something like 9 different species here. AC 14:36 How many crickets are in this room, do you think? RH 14:39 Oh, in this, crickets in this room. If we include all the babies and the adolescents and everybody growing up, we probably have, oh, 100,000 crickets, conservatively. Because we have 8 dishes going all the time, and so we get tremendous hatches of crickets babies which we have to cull out. And at any one time, in order to feed the flies, we need to maintain, we need to keep hundreds of adults coming through the pipeline to make sure that we can maintain the flies. Because the fly life cycle is completed in about 3 weeks, but a cricket takes about two and a half to three months, so you can see that if we didn¿t have a lot of crickets on hand, we would quickly, the fly generations would be, we¿d only have enough to maybe maintain two or three fly generations and then we¿d be out of luck. AC 15:40 Hold on just a second. They¿re not singing as much as they were. Is that because we¿re talking? RH 15:49 No, I think we actually hear more that you think we are. There are, they¿re not as loud, but what we¿ve got, so we¿ve got Teleogryllus, that¿s one of the Australian species. There goes the German species, there goes the Mediterranean chirper. I think I hear Gryllus rubens, the Florida one. Yes, we have three different species singing right now. You know, one of the problems may be the humidity seems a little low. They¿re very sensitive to conditions and, oops, I¿m sorry (ran into mic) AC 17:15 These are what, 10 gallon? RH 17:19 These are 30 gallon, these 30 gallon garbage cans. AC 17:22 So 30 gallon garbage cans with plastic lids and a little kind of air vent in the lid and the crickets are, live in here? RH 17:32 Why don¿t I open up a bunch of them, okay? Because once I open them up, they¿re going to be a little bit disturbed and then they won¿t sing for a few minutes. So, oops, that one already has. Let me open up some of ... (Notes truncated)
