Table 2. Pest-Specific Strategies, Biological Controls, Supplemental Pesticides, and Outcomes

Insect pest¹	Disease Trend	System Design/Management strategies	Biological controls²	Off-farm inputs and supplemental pesticides
Aphids (many spp., especially Myzus persicae) Crops: peach, plum, pluot, cherry, apple		Embed 1 to 1.5-acre fields in native oak/pine forest and separate them with native habitat on 90% of field margins (Fig. 2: Farm Fields & Soils Map). Plant a no-till living mulch (grass/clover/weeds) in crop row middles and interspersed beneath crop trees. Mow selectively to increase predator and parasite populations and activity.	*Syrphids, spiders, lady beetles, soldier beetles, parasitoid wasps	None
Western flower thrips (Frankliniella occidentalis) Crop: peach			*Banded thrips, crab spiders	2007–2013: Spinosad (Entrust) 2014 and 2015: no pesticides applied
Peach twig borer (Anarsia lineatella) Crop: peach			**Insects and birds	1998–2005: Bt (Bacillus thuringiensis) 2006–2015: no pesticides applied
Oriental fruit moth (Grapholitha molesta) Crop: peach			**Insects and birds	1998–2005: Bt (Bacillus thuringiensis) 2006–2015: no pesticides applied
Codling moth(Cydia [Laspeyresia] pomonella) Crops: apple, pear			**Insects and birds	1998–1999: Bt (Bacillus thuringiensis) 2000–2015 no pesticides applied
Spotted wing drosophila (Drosophila suzukii) Crops: cherry, kiwi, peach	No change		No biological control observed	2008–2013, 2015: two or three applications of Spinosad (Entrust) on cherries only 2014: no pesticides applied
Supporting data is from spray records, farmer observations, crop monitoring records ¹For a list of common pests and their management in California, see University of California IPM Pest Management Guidelines: • Peach: http://www.ipm.ucdavis.edu/PMG/selectnewpest.peach.html • Apple/pear: http://www.ipm.ucdavis.edu/PMG/selectnewpest.apples.html ²=detected feeding on or parasitizing pests; *= observed and hypothesized as control
