Abstract:
... Within the agrifood sector, the production of high yields is a driver for UK orchard husbandry. Currently, orchard tree management is typically a non-discriminatory method with all trees subjected to the same interventions. Previous studies indicate that structural complexity of individual orchard trees is an indicator for future yield, which can guide the management of individual trees. However, ...

Abstract:
... The banana thrips (Thrips hawaiiensis), which is one of the most common flower-inhabiting thrips, currently causes serious damage to banana trees in China. As spray treatments have low efficacy to control this thrips pest, changing to new control measures are crucial. Among the available approaches, injection of a systemic insecticide is considered suitable. However, little is known about this app ...
