The red gum lerp psyllid, Moore (Hemiptera: Aphalaridae), is an invasive pest of Eucalyptus trees worldwide, responsible for serious damage, including the death of plants. Knowledge about the incidence of climatic factors on the insect development are essential to define useful strategies for controlling this pest. To this aim, has been sampled by two different methods from April 2012 to February 2013 in eastern Sicily on in nine different sites, where the main climatic data (air temperature, relative humidity, and precipitation) have been also registered. The population showed a similar trend in all nine sites, positively correlated only with air temperature, but a negative correlation has emerged with precipitation and relative humidity. The results show the need for a deeper understanding of the role played by other abiotic (such as different concentrations of CO2) and biotic (e.g., the antagonistic action of natural enemies, competition with other pests, etc.) factors. The greater sensitivity, even at low densities of psyllid, of sampling methods based on the random collection of a fixed number of leaves compared to methods based on the collection of infested leaves in a fixed time interval has been also outlined.
红胶木虱，Moore（半翅目：粉虱科），是一种危害全球桉树的入侵害虫，会造成严重损害，包括植物死亡。了解气候因素对该昆虫发育的影响对于制定有效的害虫防治策略至关重要。为此，在2012年4月至2013年2月期间，于西西里岛东部的9个不同地点，采用两种不同方法对其进行了采样，并记录了主要气候数据（气温、相对湿度和降水量）。在所有9个地点，木虱种群呈现出相似的趋势，仅与气温呈正相关，但与降水量和相对湿度呈负相关。结果表明，需要更深入地了解其他非生物因素（如不同浓度的二氧化碳）和生物因素（如天敌的拮抗作用、与其他害虫的竞争等）所起的作用。还概述了与基于在固定时间间隔内收集受侵染叶片的方法相比，基于随机收集固定数量叶片的采样方法对木虱即使在低密度时也具有更高的敏感性。
