White pine weevils continue to be active on untreated terminals of eastern white pine at our study site in Perry County. This is the first week we have not collected adults in the detection traps. The wilting of new growth on the terminals is very evident and larvae are feeding beneath the bark. Cutting out infested terminals is the best way to control white pine weevil at this time. Pine needle scale crawlers and settled crawlers were found in Lebanon, Snyder and York counties.
Some eggs are still unhatched.
The presence of multiple stages of this pest is one of the reasons a second application of pesticide is required to achieve acceptable control. Twice-stabbed ladybeetles were actively feeding on the scale insects at one site. This predator is effective in reducing populations but usually does not show up until the infestation is severe. Rhabdocline fruiting bodies continue to disperse spores at many locations in central Pennsylvania. Some growers have started to apply their third application of protective fungicide to protect this year s growth.
