“…Dual monitoring for both the appearance of migrating psyllids and detection of liberibacter-infective psyllids is crucial to ZC management, although it is unlikely to guarantee completely ZC-free potatoes. Chemical control (Goolsby et al 2007, Gharalari et al 2009, Yang et al 2010, Butler et al 2011, Peng et al 2011 would be valuable to reduce the number of infective-psyllids and in lowering the impact of noninfective psyllids that are still capable of causing injury related to psyllid yellows disease (Wallis 1955).…”

In plant pathosystems involving insect vectors, disease spread, incidence, and severity often depend on the density of the vector population and its rate of infectivity with the disease pathogen. The potato psyllid, Bactericera cockerelli (Sulc), has recently been associated with zebra chip (ZC), an emerging and economically important disease of potato in the United States, Mexico, Central America, and New Zealand. "Candidatus Liberibacter solanacearum," a previously undescribed species of liberibacter has been linked to the disease and is transmitted to potato by B. cockerelli. Experiments were conducted under laboratory and field conditions to determine the impact of B. cockerelli density on ZC incidence, potato yield, and tuber processing quality. Insect densities ranging from one to 25 liberibacter-infective psyllids per plant were used during the experiments. Results showed that a single adult potato psyllid was capable of inoculating liberibacter to potato and causing ZC disease after a 72-h inoculation access period and was as damaging as 25 psyllids per plant. In addition, ZC-diseased plants showed a sharp reduction in tuber yield but the disease response was independent of the density of psyllids. Furthermore, both glucose and sucrose were found to have highly elevated concentrations in ZC-diseased potato tubers compared with noninfected ones and psyllid density did not vary the response. The high reducing sugar concentrations found in ZC-infected potato tubers are believed to be responsible for browning and reduced quality in processed ZC-infected tubers. This information could help ZC-affected potato producers in making effective management decisions for this serious disease.

“…Most importantly, pesticides may have limited disease control as they may not kill the potato psyllid fast enough to prevent liberibacter transmission to potato. However, some conventional and biorational pesticides, including plant extracts, mineral oils and kaolin, have shown some substantial deterrence and repellency effects to potato psyllid feeding and oviposition (Gharalari et al 2009;Yang et al 2010;Butler et al 2011;Lacey et al 2011;Peng et al 2011) and could be useful tools in integrated pest management programs to manage ZC and its psyllid vector. Nonetheless, identification and development of host plant resistance to ZC could provide the most effective and sustainable means to manage this potato disease.…”

“…Research on direct management of TPP in New Zealand has primarily been based on synthetic insecticides, with some investigation of the potential of biorational pesticides (Berry et al 2009;Yang et al 2010;Page-Weir et al 2011;DiazMontano & Trumble 2013;Jorgensen et al 2013). The arrival of TPP in New Zealand led to potato, tomato and pepper growers increasing their frequency of insecticide use, which disrupted integrated pest management programmes that were already in place for tomato and pepper (Workman & Pedley 2007;Cameron et al 2009;Gharalari et al 2009;Teulon et al 2009;Kale 2011).…”

Tomato potato psyllid (TPP; Bactericera cockerelli) is a serious pest of solanaceous crops in New Zealand. Control of TPP is currently dominated by synthetic biocides, although this method is curative and does not always prevent transmission of TPP-vectored plant diseases. This study evaluated mesh crop covers as non-chemical alternatives for controlling TPP in potato crops. Over two growing seasons in Canterbury, New Zealand, potatoes growing under mesh covers were found to have reduced numbers of TPP nymphs and adults, increased tuber size, increased overall yield and enhanced storage potential compared with uncovered plots. There was also a slight reduction in potato blight spores under mesh, and the actual occurrence of blight was slightly reduced in one trial. The results of this study indicate that mesh crop covers could provide a viable option for potato growers who wish to protect their crops from TPP without using chemical insecticides.
