Abstract

The tomato potato psyllid Bactericera cockerelli (TPP) and the bacterium it vectors Candidatus Liberibacter solanacearum (CLso) are collectively responsible for significant economic losses across New Zealands horticulture industry Crop host plants of TPP include potatoes tomatoes capsicums/ chilli peppers tamarillos and tobacco along with lessobvious species outside the Solanaceae family such as kumara (Convolvulaceae) Most of these plants are shortlived summer annuals which raises the question what happens to TPP when crops are absent Many less conspicuous noncrop plants also play host to TPP some of which are perennial and therefore present yearround potentially acting as reservoirs of both TPP and CLso in the absence of a crop A pilot study in 2012 and subsequent vegetation surveys in Canterbury and Hawkes Bay in 201314 confirmed the presence of all TPP life stages on multiple noncrop species yearround in both areas despite adverse climatic events such as winter frosts and snowfall These results have farreaching impacts on the way growers should manage the borders surrounding their crops and their land in the offseason
