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，由于侵入性的果蝇（SWD），由于侵入性果蝇造成的损害，80％的商业柔软水果可能会因废物而丢失。种植者依靠全田喷雾剂的化学绝缘材料来保护水果免受SWD的侵害，成本为110亿英镑。最近，草莓种植者还记录了ear损伤的事件增加，在草莓作物的高峰时段作物损失为10-30％：目前在草莓作物中没有有效的这种绝缘措施，即使ear虫实际上对苹果园有益，也对苹果果园有益，以多种昆虫为食，例如aphids。对于苹果种植者来说，玫瑰色的苹果蚜虫（RAA）是造成巨大产量和质量损失的主要害虫。春季，树木中存在蚂蚁在树上的存在加剧了RAA损害，这趋向于蜂蜜冬季的蚜虫。这些蚂蚁保护其有价值的“蚜虫农场”免受通用昆虫捕食者的预测，如霍夫蝇幼虫和瓢虫。我们已经确定了一种由天然产品制成的诱饵，该诱饵以SWD为食（Probandz）和低剂量的杀虫剂可用于使用少于95％的杀虫剂，以保护杀虫剂，以保护该杀虫剂，以保护杀虫剂，以保护杀虫剂，以保护crops的杀虫剂。在这个项目中，我们将与低剂量的替代杀虫剂结合使用新的诱饵Probandz，从而降低了SWD杀虫剂耐药性的风险，完全减少了水果中残基的水平。我们将开发一种更具针对性且对环境破坏性更少的SWD控制方法。在草莓作物中，我们将使用配方的诱饵和防逃避陷阱的组合将陷阱毛毛杀死。 Eartigs可以随后以害虫控制剂的形式释放到苹果园中，以创建一种可持续的方法。要完成RAA控制，我们将使用配制的Probandz吸引从蚜虫菌落中喂养蚂蚁，从而使蚜虫更容易受到自然敌人的攻击，从而导致较少的蚜虫受损的果实。
