Sticky pane monitoring of Froggatt's apple leafhopper and two beneficial insects in three orchard management systems

ABSTRACT
A convenient monitoring system for a range of pipfruit arthropods was investigated as part of the development of Integrated Fruit Production for apples. The monitoring system, based on clear sticky panes, was used to monitor adults of Froggatt’s apple leafhopper (Edwardsiana crataegi) and two beneficial insects (Sejanus albisignata and Micromus tasmaniae) in Canterbury apple orchards under three management regimes over three seasons. The results reconfirmed the presence of two generations of Froggatt’s apple leafhopper and S. albisignata in Canterbury. Differences in pest and beneficial insect abundance were evident between the three orchard production systems. Numbers of S. albisignata were consistently lowest in the conventional fruit production system, but this was not the case for M. tasmaniae or E. crataegi.
Keywords: apple, phenology, apple leafhopper, Sejanus albisignata, Micromus tasmaniae.
