Bark Beetle (Scolytidae) in Croatian Orchards
According to data in the literature, the bark beetle appears mainly on weakened fruit trees of different scion varieties. Thus, stronger populations may be found on trees damaged by low temperatures, drought, rodents, or diseases of the roots or crown. Only in exceptional circumstances, with the appearance of a strong bark beetle population, were they believed to attack sound, healthy trees. However, in Croatia recently the bark beetle has appeared more frequently on sound young and old trees, as well as on fruit seedlings, either in the nusery-garden or in young orchards containing recently planted fruit-trees. The appearance of the bark beetle was monitored by the method of infested tree inspection. The pathogenicity of the bark beetle on infested trees has been assessed. In the assessments of the populations and intensity of the incidence of adults, baits of ethanol (ethyl alcohol) diluted with water have been used. The method of control, that involves catching the adults, has been tested, as well as the method of insecticide application into galleries and tunnels of infested trees. This investigation of the bark beetle showed prominent pathogenic and pernicious effect of the beetle, or the fungus living inside the gallery of the infested tree, respectively. The investigation showed good impact of insecticides applied in increased concentrations, after being injected into the bark beetle galleries. Experimental control of the bark beetle by catching the adults has also showed good results.
