“…Like other clade 6 species, P. lacustris is commonly aquatic and tolerant of high temperatures (Nechwatal et al, 2013), but may cause consequential damage under certain conditions (Jung et al, 2011;Kanoun-Boulé et al, 2016). The pathogenicity of P. lacustris on different host species does not appear to be fully recognized (Nechwatal et al, 2013;Nowak et al&, 2015;Orłikowski et al, 2012).…”

In western Ukraine, forest decline and dieback of several broadleaved tree species have become increasingly evident during recent years, and surveys in some areas have shown symptoms indicative of Phytophthora infections. In this study, we aimed to determine the occurrence and diversity of Phytophthora species associated with several broadleaved tree species (Alnus glutinosa, Betula pendula, Castanea sativa, Fagus sylvatica and Quercus robur) from forest stands where dieback has been observed. Rhizosphere soil samples were collected from 14 forest stands during 2017 and 2018 and tested for the presence of Phytophthora species using morphological and molecular methods. Seven Phytophthora species (P. bilorbang, P. cactorum, P. gallica, P. gonapodyides, P. lacustris, P. plurivora and P. polonica), and two other clade six taxa were detected from the various forest types, several of which are probable agents responsible for decline. Four of the Phytophthora species (P. bilorbang, P. gallica, P. plurivora and P. polonica) have previously never been reported from broadleaf forests in Ukraine.

“…The Aleyrodidae fly population was found to be significantly different in selected regions, and endosymbionts of Hamiltonella, Rickettsia, Fritschea, Cardinium, Arsenophonus, and Wolbachia were recorded in promotions to the Aleyrodidae fly population. The Hamiltonella co-infection percentages in Faisalabad, Chiniot, Sargodha, Jhang, T. T. Singh, and Burewala were recorded as 51,28, 75,8,23, and 25, respectively, whereas relative abundance percentages of Hamiltonella endosymbiont were recorded as 52, 35, 65, 5, 20, and 21 in Faisalabad, Chiniot, Sargodha, Jhang, T. T. Singh, and Burewala, respectively. A similar trend was observed for Rickettsia, Fritschea, Cardinium, Arsenophonus, and Wolbachia co-infection and relative abundances.…”

Aleyrodidae fly is a vector carrier of various diseases in crops, plants, and vegetables. The present investigation evaluated the Aleyrodidae fly population for its relationship with cotton disease under different environmental conditions. Faisalabad, Chiniot, Sargodha, Jhang, Toba Tek Singh (T. T. Singh), and Burewala from Punjab, Pakistan were selected for this study. The Aleyrodidae fly population was found to be significantly different in selected regions, and endosymbionts of Hamiltonella, Rickettsia, Fritschea, Cardinium, Arsenophonus, and Wolbachia were recorded in promotions to the Aleyrodidae fly population. The Hamiltonella co-infection percentages in Faisalabad, Chiniot, Sargodha, Jhang, T. T. Singh, and Burewala were recorded as 51,28, 75,8,23, and 25, respectively, whereas relative abundance percentages of Hamiltonella endosymbiont were recorded as 52, 35, 65, 5, 20, and 21 in Faisalabad, Chiniot, Sargodha, Jhang, T. T. Singh, and Burewala, respectively. A similar trend was observed for Rickettsia, Fritschea, Cardinium, Arsenophonus, and Wolbachia co-infection and relative abundances. Results revealed that the Aleyrodidae fly is a carrier of different endosymbionts, which were significantly different under different environmental conditions.

“…One other vector of spread of Phytophthora is through waterways. Internationally studies have shown water to be a significant disperser of spores and hyphae [27][28][29]. The extent to which this occurs in New Zealand has not been documented, mainly due to a previous lack of tools for detection of Phytophthora agathidicida in water.…”

In Aotearoa/New Zealand, the soilborne pathogen Phytophthora agathidicida threatens the survival of the iconic kauri, and the ecosystem it supports. In 2011, a surveillance project to identify areas of kauri dieback caused by Phytophthora agathidicida within the Waitākere Ranges Regional Park (WRRP) highlighted the potential impact of the pathogen. A repeat of the surveillance in 2015/16 identified that approximately a quarter of the kauri area within the Regional Park was infected or possibly infected, an increase from previous surveys. The surveillance program mapped 344 distinct kauri areas and showed that 33.4% of the total kauri areas were affected or potentially affected by kauri dieback and over half (58.3%) of the substantial kauri areas (above 5 ha in size) were showing symptoms of kauri dieback. Proximity analysis showed 71% of kauri dieback zones to be within 50 m of the track network. Spatial analysis showed significantly higher proportions of disease presence along the track network compared to randomly generated theoretical track networks. Results suggest that human interaction is assisting the transfer of Phytophthora agathidicida within the area. The surveillance helped trigger the declaration of a cultural ban (rāhui) on recreational access. Te Kawerau ā Maki, the iwi of the area, placed a rāhui over the kauri forest eco-system of the Waitākere Forest (Te Wao Nui o Tiriwa) in December 2017. The purpose of the rāhui was to help prevent the anthropogenic spread of kauri dieback, to provide time for investment to be made into a degraded forest infrastructure and for research to be undertaken, and to help protect and support forest health (a concept encapsulated by the term mauri). Managing the spread and impact of the pathogen remains an urgent priority for this foundation species in the face of increasing pressures for recreational access. Complimentary quantitative and qualitative research programs into track utilization and ecologically sensitive design, collection of whakapapa seed from healthy and dying trees, and remedial phosphite treatments are part of the cross-cultural and community-enabled biosecurity initiatives to Kia Toitu He Kauri “Keep Kauri Standing”.
