Globally, 80% of commercial soft fruit can be lost as waste due to damage caused by an invasive fruit fly, spotted wing drosophila (SWD). Growers rely on full field sprays of chemical insecticides to protect fruit from SWD, costing £11bn. Recently strawberry growers have also recorded increasing incidence of damage from earwigs with crop losses of 10-30% at peak times in strawberry crops: currently there are no effective control measures for this insect in strawberry crops, even though earwigs are actually beneficial in apple orchards, feeding on a variety of insect pests such as aphids. For apple growers, rosy apple aphid (RAA) is a major pest causing significant yield and quality losses. RAA damage is exacerbated by the presence of ants in the trees in the spring which tend the aphids for their honeydew. These ants protect their valuable 'aphid farms' from predation by generalist insect predators like hoverfly larvae and ladybirds.We have identified a bait made from a natural product which SWD feeds on (ProBandz) and in combination with low doses of insecticide can be used to control this pest using less than 95% of insecticide that is normally sprayed to protect crops. In this project we will test our new bait, ProBandz, in combination with low doses of alternative insecticides, thereby reducing the risk of SWD insecticide resistance simultaneously reducing levels of residues in the fruit. We will develop a more targeted and less environmentally damaging approach to SWD control.In strawberry crops we will live trap earwigs using a combination of formulated bait and escape proof traps. Earwigs can be later released into apple orchards as a pest control agent creating a sustainable approach.To accomplish RAA control, we will use a formulated ProBandz to attract feeding ants away from the aphid colonies, making the aphids more vulnerable to attack from natural enemies, resulting in fewer aphid damaged fruits.

在全球范围内，80%的商业软水果可能会由于入侵果蝇（斑点翅果蝇）造成的损害而作为废物损失。种植者依靠化学杀虫剂的全面喷洒来保护水果免受SWD的侵害，成本为110亿英镑。最近，草莓种植者也记录了越来越多的发生率，在草莓作物的高峰期，作物损失达10-30%：目前草莓作物中没有有效的控制这种昆虫的措施，尽管在苹果园中，以各种害虫如蚜虫为食的虱实际上是有益的。苹果红蚜是苹果生产中的主要害虫，对苹果的产量和品质造成严重损失。在春季，树上的蚂蚁会照料蚜虫以获取蜜露，从而加剧了蚜虫的危害。这些蚂蚁保护它们宝贵的“蚜虫农场”，免受食蚜蝇幼虫和瓢虫等多面手昆虫掠食者的捕食。我们发现一种由社署以之为食的天然产品制成的诱饵（ProBandz），配合低剂量的杀虫剂，可用于防治这种害虫，所用的杀虫剂少于通常喷洒以保护作物的杀虫剂的95%。在这个项目中，我们将测试我们的新诱饵，ProBandz，结合低剂量的替代杀虫剂，从而降低SWD杀虫剂耐药性的风险，同时降低水果中的残留水平。我们会制订一套更有针对性和对环境破坏较少的方法，以防治社署的虫鼠。我们会在草莓种植时，使用特制的饵剂和防逃逸的诱捕器，以诱捕的方法诱捕。为了实现对蚜虫的控制，我们将使用ProBandz配方，将觅食蚂蚁吸引到远离蚜虫群落的地方，使蚜虫更容易受到天敌的攻击，从而减少蚜虫对果实的破坏。
