A large population of Asian citrus psyllids and nymphs was found in an older section northwest of Visalia this past week, with Tulare County and California officials moving into eradication mode immediately. Making matters worse is that multiple life stages were found in the specific properties.

Officials say four local homeowners are cooperating as some 400 ACP were found. Preliminary testing of the trees does not indicate huanglongbing in the area. 

All four sites have been treated, and precautionary treatments in a surrounding area will commence after a public meeting and notices are distributed to homeowners. Fortunately for the citrus industry, there is no commercial citrus within a mile of the location and a 100m survey was conducted with no additional finds. Enforcement staffs are reviewing traps in the area on a daily basis until further notice.

California Citrus Mutual officials say the find brings back the reminder that moving clean bins through an area is of paramount importance. Bins moving from a packing house into a production area can carry ACP hitchhikers. Growers need to monitor the arrival of such bins as the transportation routes, in this case Highways 63, 65, 198, and 99, are vulnerable pathways for ACP distribution.

The find follows the recent discovery of a breeding population of Asian citrus psyllids on four sites in Maricopa, Calif., in rural Kern County. The discovery raised concerns as it appeared within a short distance of commercial citrus groves.
