Yeah, mostly almonds. To be more specific almonds although they will wind pollinate are greatly helped by insect pollinatin and the added yield affords them the money with which to pay bee keepers to come in and put their bees there for a month and then they are done. I think the bee keepers get $80/hive for the month. They put the bees out usually at night while they are inactive so you just usually see the out of state bee guy's rigs at the motel in the morning. They usually have a flat bed 2 axle truck with a trailer and an articulated swinger with a forklift mast or a skidsteer to unload/load the bee hives. The other crops that use bees like melons and stuff are usually serviced by the local bee guys. Deva is right about the wild bees, there are almost none left, and the ones left are usually severely weakened by the two mites I mentioned.Is this just for pollination of crops ?
