Exporting apples to China is now a possibility again for Washington producers - sort of. China is now requiring that the 'Manchurian' crabapple pollenizers in apple orchards be pruned to qualify an orchard to be eligible for export to China. NHC and NFE are offering 2 pruning demonstrations for the industry. The first is in George/Quincy on March 20 at 2pm; the other is in Pateros on March 21 at 10am. For more information visit the NHC website at:

Very cool image of the pear psylla parasitic wasp emerging from the mummified host.

Scanning Electron Microscopy of Arthropods and Other Organisms updated their status.

This is not a good week for pear psylla. Yesterday I featured a predatory ant eating one and today I have a parasitoid of the psylla. The wasp is probably Tre...chnites sp. (Hymenoptera: Encyrtidae) and is shown emerging from it's host a pear psylla, Cacopsylla pyricola (Hemiptera: Psyllidae). The wasp lives inside of the psylla and consumes the internal organs, eventually killing the psylla. It pupates inside the mummy and the adult wasp emerges from the dead host. Not unlike the movie "Alien". Please share if you enjoy this page. All images are copyrighted.
