Raising Japanese Beetles over the winter
I'm going to be attempting, next summer, to obtain one mating pair of beetles and quite a few mated female beetles. (I would assume the beetle on the bottom of the mating pairs?) I will keep them indoors to raise for their grubs to, hopefully, have a continuous supply of in vitro parasitic nematodes.
If anyone knows a better culture, than the usual for pet beetles, let me know. I would obviously have a separate cantainer of the nematodes, to which I would be adding grubs every seven days or so, until the outside soil was warm enough for release. I realize the beetles may not like this, but unfortunately I do not like them eating everything in my yard.
Anyone know if the nematodes reproduce in earthworm eggs? I know they don't bother the adults, but I always have plenty of earthworm eggs on hand. I will also be trying the same thing with the masked chafer beetles.
