Theme: Agriculture and Food SecurityI will examine the effects of disease on plant-insect interactions using Solanum species present in UK gardens: tomato; potato; aubergine, and the ornamentals Solanum crispum, S. laxum, S. aviculare and others. The viral pathogens to be examined will be those most predominant identified by my survey of viruses affecting Solanum species in UK gardens undertaken in the summer of 2015. The samples are currently being analysed but these Solanum-infecting viruses are likely to be isolates of Potato virus Y and CMV (aphid-transmitted), as well as tobamoviruses (Tobacco mosaic virus and Tomato mosaic virus) and Potato virus X (not aphid transmitted). I will examine the effects of the selected viruses on colonisation, feeding behaviour, survival and performance of larva of the chewing insect Manduca sexta and the aphids Myzus persicae (a non-specialist) and Macrosiphum euphorbiae (Solanum specialist), both of which vector a variety of viruses. Bee responses to visual and olfactory cues emitted by healthy versus diseased plants will be investigated using free choice and conditioning assays. Insect responses will be correlated with changes in plant volatile emission (Using GC-MS) and in plant soluble factors e.g. in nectar using LC-MS.

布景主题：农业和食品安全我将研究疾病对植物和昆虫相互作用的影响，使用英国花园中的茄属物种：番茄、马铃薯、茄子和植物茄。laxum、松藻S. aviculare等。待检查的病毒病原体将是我在2015年夏天对英国花园中影响茄属物种的病毒进行的调查中确定的最主要的病原体。目前正在对这些样本进行分析，但这些感染Solpendi的病毒很可能是马铃薯Y病毒和CMV（蚜虫传播）的分离株，以及烟草花叶病毒（烟草花叶病毒和番茄花叶病毒）和马铃薯X病毒（非蚜虫传播）。我将研究所选病毒对咀嚼昆虫Manduca sexta和蚜虫Myzus persicae（非专家）和Macrosiphum euphorphium（Solanum专家）幼虫的定殖，摄食行为，存活和性能的影响，这两种病毒都是各种病毒的载体。蜜蜂的视觉和嗅觉信号发出的健康与患病植物的反应将进行调查，使用自由选择和条件试验。昆虫的反应将与植物挥发性排放（使用GC-MS）和植物可溶性因子（例如使用LC-MS的花蜜）的变化相关。
