DescriptionIn this presentation I will address three points associated with pear thrips damage and sugar maple. First, I will describe the impact of pear thrips on sugar maple in Massachusetts, in both the sugarbush and the natural forest stand, based on root starch assays that were completed this fall (1988). Secondly, I will discuss the relationship between tree health and thrips damage, specifically addressing the question of whether this insect preferentially selects trees or stands of trees having high or low vigor. Finally, I will offer some speculative comments concerning the influence of air pollutants (e.g., ozone) on the sugar maple/pear thrips interaction.
