Thanks all for the helpful comments. I do intend to repeat this next fall in the same yard with Medhat's recommendations on swapping out sticky boards. I'll see if treatment drops lower than pre-treatment drops happens again in that yard. Brion, to alleviate the daily variability, I divided the gross mite drop by the number of days. I will better address trends over days by swapping out boards more often. I may do this in conjunction with alcohol washes in the future. I just like the quick in-n-out time and that a stack of stickies can be counted at home with my feet up. It's probably more time to count a sticky board than perform the alcohol wash, but it's less to swap a sticky board. Daylight time is pretty valuable. *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
