Synopsis: Tedders trap using pheromone combination lures in peach. Newly emerging nymphs and 1st generation adults have been on the increase, nearing or exceeding threshold in Highland and New Paltz in Ulster County. The 2nd instar of Brown Marmorated Stink Bug (BMSB) Halyomorpha halys (Stål), newly hatched from eggs last week, are making their way to traps and increasing in numbers throughout the state. All life stages along commercial blocks in mid-Hudson Valley orchard sites have been observed this past week. Movement to apple foliage and fruit is beginning. Trap numbers of stink bug in com ..read more

Green Stink Bug Adult on Pink lady near harvest, 2017 Synopsis: Over the past week stink bug have begun feeding on tree fruit, albeit in low numbers along the orchard perimeter. The two native species including the native green stink bug (GSB), Acrosternum hilare (Say) and brown stink bug (BSB) (Euschistus servus) (Hemiptera: Pentatomidae) have been moving from deciduous forest trees and broadleaf border plants to tree fruit, feeding on apple in some orchard blocks across the region. In early August we began to see the very wet July conditions (7.05″ New Paltz, NY) begin to dry down some. In d ..read more

BMSB Adult and Late Season Apple Injury This season we are experiencing a surprisingly low number and likely late start to the emergence, egg laying and nymph development of the invasive brown marmorated stink bug (BMSB) given the early maturity of fruit this year. Scouting for the insect in trees has shown very few BMSB nymphs in mid-late stages of development with adults at the onset of emergence. That said, we have not yet seen threshold numbers in commercial orchards in Tedders or sticky card traps. The presence of eggs and early instar nymphs found over the next few weeks may indicate the ..read more

Brief: The crop load of many varieties appears to be robust in most orchards this season. Predictions are for a strong crop in the Hudson Valley with many blocks exceeding 1000 bushels to the acre are forecast. In tall spindle systems with trees in their 4th leaf and older, many growers are pushing the upper limits of support systems designed for a 10′ tall tree. At 12′ to 14′ row spacing, gaining an additional 5-15% fruit load above the top wire is enticing but not without considerable stress. Without additional support in years with a heavy crop, these systems are increasingly at risk for f ..read more

Brief: Increasing populations of Woolly Apple Aphid (WAA) have been observed this morning, most problematic in Fuji apple in Orange County. The aphid feeds on the sap from plants, excreting or ‘shunting’ excess and concentrated sap will act as a substrate for sooty mold while high infestations can colonize the calyx end of fruit becoming problematic at harvest. The WAA tends to be a sporadic pest in orchards in the northeastern United States, occurring in high numbers only every few years. However, through the use of pyrethroids for the control of the brown marmorated stink bug we are seeing f ..read more
