“…A clear elucidation of the importance of entry points that may vary throughout the season, can enable fine-tuned disease management strategies based on the plant-pathogen phenological synchrony for enhanced plant protection. Furthermore, cultivar factors influencing host-pathogen interactions are central for the appropriate selection of resistance genotypes in breeding programmes [29].…”

Since 2008, the kiwifruit industry has been devastated by a pandemic outbreak of Pseudomonas syringae pv. actinidiae (Psa), the causal agent of bacterial canker. This disease has become the most significant limiting factor in kiwifruit production. Psa colonizes different organs of the host plant, causing a specific symptomatology on each of them. In addition, the systemic invasion of the plant may quickly lead to plant death. Despite the massive risk that this disease poses to the kiwifruit industry, studies focusing on Psa ecology have been sporadic, and a comprehensive description of the disease epidemiology is still missing. Optimal environmental conditions for infection, dispersal and survival in the environment, or the mechanisms of penetration and colonization of host tissues have not been fully elucidated yet. The present work aims to provide a synthesis of the current knowledge, and a deeper understanding of the epidemiology of kiwifruit bacterial canker based on new experimental data. The pathogen may survive in the environment or overwinter in dormant tissues and be dispersed by wind or rain. Psa was observed in association with several plant structures (stomata, trichomes, lenticels) and wounds, which could represent entry points for apoplast infection. Environmental conditions also affect the bacterial colonization, with lower optimum values of temperature and humidity for epiphytic than for endophytic growth, and disease incidence requiring a combination of mild temperature and leaf wetness. By providing information on Psa ecology, these data sets may contribute to plan efficient control strategies for kiwifruit bacterial canker. Keywords Actinidia chinensis Planch. var. chinensis.

“…Two species of armoured scale insects have previously been recorded on A. arguta fruit: the non-actionable Hemiberlesia lataniae (latania scale) and the quarantine pest Hemiberlesia rapax (greedy scale) (Mauchline & Hill 2005;McKenna et al 2007). The two species are closely related and similar in appearance.…”

The key insect pests of Actinidia arguta kiwifruit were determined by monitoring tagged fruit bunches for insects and insect damage in six orchard blocks from fruit set in November 2007 until harvest in February 2008 and by examining samples of picked fruit at harvest The proportion of fruit damaged by leafroller feeding increased throughout the entire growing season and live caterpillars were present on picked fruit at harvest Greenhouse thrips damage to fruit was noticeable from mid January Armoured scale insects and mealybugs were recorded on the fruit from December but most infestations occurred during the month prior to harvest Leafrollers and greenhouse thrips are the key production pests while leafrollers greedy scale and some mealybug species are potential quarantine species All three commercial A arguta cultivars grown in the Bay of Plenty are susceptible to the key pest species
