Insect management - monitoring | New England Tree Fruit Management Guide

Monitoring is done in a systematic manner according to accepted IPM guidelines. Records are kept of all monitoring information collected.
Bark of rootstock, trunk and limbs is monitored for San Jose scale, winter moth, woolly apple aphid or borers, where appropriate.
Tarnished plant bug is monitored by white visual sticky traps or visual inspection of buds.
Leafminers are monitored by foliar inspection for first generation mines.
Foliage is sampled for mites and mite predators.
Fruit clusters are examined pre-bloom for pug moth and/or winter moth.
Fruit is monitored for fresh plum curculio injury following initial cover spray to time additional sprays, if needed.
European apple sawfly is monitored by white visual traps.
Pheromone traps are used to monitor Oriental fruit moth, codling moth, and oblique banded leafroller, and for determining biofix (first sustained trap catch).
Terminal foliage is monitored for aphids and aphid predators.
Monitoring for leafhoppers (fruit clusters for white apple LH and rose LH; terminal growth for potato LH) is conducted.
Brown marmorated stink bug is monitored with pheromone traps
Apple maggot fly is monitored by red sticky spheres that can be either unbaited or baited with an apple-based lure.
Fruit and foliage are monitored for codling moth, fruitworm and leafroller larvae or injury, where appropriate.
