Pear IPM: Area-wide movement patterns of psylla and its interaction with chemical use and natural enemy abundance.
Author: Tom Unruh
Published: 2002
Summary: Measure pear psylla nymph and adult abundance, beneficial insect abundance, chemical use patterns and tree vigor in ca. 30 PIPM and 10 conventional blocks (2001) 2) Collect psylla adult abundance in spring and fall to describe more completely movement among orchards (2000) 3) Use multivariate and spatial statistical methods to identify the factors most predictive of good psylla control and provide a prescription for best IPM practices based on 1999-2000 Pew-EPA data and our own data collected in 2001. (2000-2001) 4) Evaluate accuracy of presence-absence sampling methods for psylla nymphal abundance. (2000-2001)
