A volatile compound 2undecanone increases walking but not flying tomato potato psyllid movement toward an odour source

Bactericera cockerelli (tomato potato psyllid; TPP) is an important pest of solanaceous crops in New Zealand and North America A volatile compound that alters the behaviour of TPP could be developed into a component of an integrated pest management strategy for solanaceous crops One compound 2undecanone was found to increase the percentages of female and male TPP (65 P

Ongoing Development

The tomato potato psyllid (Bactericera cockerelli (Sulc)) probably invaded New Zealand in the summer of 200506 The first authenticated records from May to June 2006 indicated that it was widely distributed in the Auckland area with a further record from Taupo so that no attempt was made to eradicate it By April 2009 records indicated that it had spread throughout much of New Zealand Its spread within New Zealand is likely to be from a combination of natural and human mediated dispersal The psyllid and the liberibacter it transmits will provide a serious challenge to the ongoing development of Integrated Pest Management in greenhouse crops (especially tomato and capsicum) outdoor tomatoes and potatoes The economic impact of this insect and disease in the 4 years it has been in New Zealand has been in millions of dollars in terms of increased management costs crop losses and loss of export markets

Diurnal Temperatures

Kyllingaspecies are becoming more prevalent in turfgrass sites throughout North America. The effects of nitrate (50, 200, and 400 mg L−1), temperature (33/24, 25/17, 19/11 C day/night, respectively), and light on seed germination of threeKyllingaspecies were investigated in growth chambers. Nitrate concentrations did not stimulateKyllingaspecies seed germination compared with untreated seeds. AllKyllingaspecies seeds failed to germinate in darkness but resumed germination once they were placed in light. This is an important pest management strategy because a dense, uniform turfgrass stand with its minimum light penetration to the soil would minimizeKyllingaspecies seed germination. Higher temperatures increased seed germination rate and percentage of each species after 8 wk. Maximal (> 90%)K. brevifoliagermination occurred 2 to 4 wk after initiation in every seed study, whereasK. squamulataseeds germinated continuously. Minimal (< 10%)K. pumilaseeds germinated until alternating diurnal temperatures were imposed.

The response to the incursion of tomato potato psyllid (TPP) Bactericera cockerelli first recorded in New Zealand in 2006 and 2008 respectively has been well documented However development of a bioprotection research programme to underpin effective crop production in the presence of TPP/CLso has not This paper examines the strategic and operational responses of the main Crown Research Institute involved in parallel with industry actions in terms of the coordination prioritisation and implementation of a proportionally increasing research programme after it became clear that eradication of these organisms was not feasible The establishment of TPP/CLso in New Zealand underlines the fragility of current integrated pest management (IPM) systems and the challenges faced by small industries to the establishment of poorly understood organisms with complex pest/disease/host plant interactions whose impacts were not immediately obvious Insights are provided into how a research response to similar establishments might be developed in the future

Management Approaches

An integrated pest management (IPM) strategy was compared with farmers’ conventional pest management practices on twelve spring- and autumn-sown seed and forage brassica crops. Demonstration trials were conducted in Canterbury from spring 2015 to autumn 2017 by splitting farmers’ paddocks in half and applying the two management approaches side by side. A farmer participatory approach was used, with management decisions based on monitoring pests and biological-control agents. Farmer and adviser training with a focus on monitoring and identification was carried out. Biological-control agents capable of contributing to pest control were identified in all brassica crops. There was a 35% reduction in the number of insecticides applied under IPM compared with conventional management, negligible crop yield differences, and the type of insecticides applied was different. IPM adoption at these farms was high by the end of the 3-year project with 11 of the 12 farmers implementing IPM across 90—100% of their brassica crops. This project was a starting point for an industry-wide change of practice to IPM, which has become more widespread since its completion.
