Abstract:

The usage of pheromones in forest pest management in Israel is directed against the pine processionary moth (PPM) Thaumetopoea wilkinsoni, the Israeli pine bast scale (IPBC) Matsucoccus josephi and the pine bark beetles Orthotomicus erosus and Pityogenes calcaratus. The sex pheromone of PPM is utilized to estimate flight periods, which in turn determines the timing of aerial treatments against the caterpillars. Pheromone traps of IPBC have been employed to estimate the scale density and whether some precautions are needed in order to avoid outbreaks. In previous studies it was found that the aggregation pheromone of the European spruce bark beetle ESBB Ips typographus serves as a powerful kairomone of O. erosus and P. calcatarus. The extent of damage inflicted by these bark beetles in local pine forests is yet unclear. Nevertheless, their outbreaks often occur after thinning operations. Climatic changes during the last decade, mainly long drought periods and availability of timber debris as a result of extreme snow storms has caused an increase in bark beetles populations in Israel forests. We have developed a setup of trap-tree procedures as a preventive measure in a situation of a developing outbreak. The effective period of the trap tree was estimated by studying the longevity of ESBB lures and the optimal concentration of a pyrethroid insecticide spray cover. We found that killing ability covers the warm season. A large setup of trap tree applications was studied in the summer of 2014, when severe outbreaks were anticipated due to the combination of dry winters and collapse of thousands of trees due to snowstorms. The operation included a monitoring scheme and the selection of treated and control stands setup using a GIS supported stochastic model, which enabled to select the stands according to their susceptibility to bark beetle attack. The usage of the pheromones will be discussed
