A spatio-temporal multi-scale fusion algorithm for pine wood nematode disease tree detection

Pine wood nematode infection is a devastating disease.Unmanned aerial vehicle(UAV)remote sensing enables timely and precise monitoring.However,UAV aerial images are challenged by small target size and complex sur-face backgrounds which hinder their effectiveness in moni-toring.To address these challenges,based on the analysis and optimization of UAV remote sensing images,this study developed a spatio-temporal multi-scale fusion algorithm for disease detection.The multi-head,self-attention mechanism is incorporated to address the issue of excessive features generated by complex surface backgrounds in UAV images.This enables adaptive feature control to suppress redundant information and boost the model’s feature extraction capa-bilities.The SPD-Conv module was introduced to address the problem of loss of small target feature information dur-ing feature extraction,enhancing the preservation of key features.Additionally,the gather-and-distribute mechanism was implemented to augment the model’s multi-scale feature fusion capacity,preventing the loss of local details during fusion and enriching small target feature information.This study established a dataset of pine wood nematode disease in the Huangshan area using DJI(DJ-Innovations)UAVs.The results show that the accuracy of the proposed model with spatio-temporal multi-scale fusion reached 78.5%,6.6%higher than that of the benchmark model.Building upon the timeliness and flexibility of UAV remote sensing,the pro-posed model effectively addressed the challenges of detect-ing small and medium-size targets in complex backgrounds,thereby enhancing the detection efficiency for pine wood nematode disease.This facilitates early preemptive preser-vation of diseased trees,augments the overall monitoring proficiency of pine wood nematode diseases,and supplies technical aid for proficient monitoring.

Study on the Control Effect of Chinese Herbal Medicine Regulator on Leaf Spot Nematode Disease of Chloranthus spicatus

[Objectives]This study was conducted to investigate the control of Chinese herbal medicine regulators on leaf spot nematode disease,the main pest of Chloranthus spicatus(Thunb.)Makino.[Methods]C.spicatus plants infected with nematodes were irrigated with a Chinese herbal medicine regulator at two different concentrations,and the control effect on leaf spot nematode disease of the plant was studied by measuring the number of nematodes,the contents of chlorophyll,malondialdehyde,soluble sugar and free proline in the leaves of the plants in the soil.[Results]Compared with the control,the two concentrations of Chinese herbal medicine regulator significantly reduced the number of nematodes in the soil,increased the contents of chlorophyll(mainly chlorophyll a),soluble sugar and free proline in the leaves of C.spicatus,and decreased the content of malondialdehyde.It indicated that the Chinese herbal medicine regulator could effectively control the spread of nematodes and had certain effect on the recovery of C.spicatus plants.[Conclusions]The use of Chinese herbal medicine regulators is helpful to curb the occurrence of leaf spot nematode disease in C.spicatus by biological prevention and control means,and provides theoretical guidance for the development of the green industry of C.spicatus.

Current Status of Soil-transmitted Nematode Infection in China

Objective To carry out national surveys for ascertaining the current status and trends of soil-transmitted nematode infections in China, providing scientific basis for further developing control strategies. Methods In 1988-1992 （hereinafter abbreriated as ＂survey in 1990＂）, a stratified cluster random sampling method was used in the survey. In 2001-2004 （hereinafter abbreriated as ＂survey in 2003＂）, in order to compare with the survey in 1990, two-characteristic stratified cluster random sampling method was used and 687 investigation spots were sampled from the 2848 spots selected in the survey in 1990. Kato-Katz thick smear method was used to examine the eggs of soil-transmitted nematodes in fecal samples. Results The prevalence rates were 53.6% and 19.6% for soil-transmitted nematodes, 14.6% and 6.120% for hookworms, 44.6% and 12.7% for Ascaris lumbricoides, 17.4% and 4.630% for Trichuris trichiura in survey 1990 and survey 2003, respectively. The prevalence rates of soil-transmitted nematodes were higher in 13 provinces than the average level in China in the survey in 1990, and higher in 8 provinces than the average level in the survey in 2003. The prevalence of hookworms, Ascaris lumbricoides, Trichuris trichiura and the overall prevalence of soil-transmitted nematodes were higher in females than in males. It is estimated from the results of survey in 2003 that the number of persons with soil-transmitted nematode infections in the country is about 129 million, less than that in the survey in 1990. Conclusion The prevalence of soil-transmitted nematodes has declined considerably but is still relatively high in some provinces and autonomous regions. Control activities and socioeconomic development may have contributed to the decreased prevalence.

[Objectives]The paper was to figure out the distribution of Monochamus alternatus in the stumps of pine wood nematode infected wood in Lu'an City and to provide a theoretical and practical basis for differentiated prevention and control of pine wood nematode disease in the future.[Methods]The factors influencing the number of epidemic small classes and infected plants in all counties and districts of Lu'an City were analyzed by GIS method,and the number of worms and wormholes of M.alternatus inside and outside the stumps of pine wood nematode infected wood in Lu'an City were investigated on the spot.[Results]There were 98,40,54,781,193,268 and 34 epidemic small classes of pine wood nematode disease,and 7241,6099,9532,39161,11079,49876 and 4853 infected plants in Yu'an District,Jin'an District,Yeji District,Shucheng County,Huoshan County,Jinzhai County and Huoqiu County,respectively.Pine wood nematode disease in Lu'an City mostly occurred in Huoshan County,Shucheng County and Jinzhai County,with relatively high altitude,paddy soil,the annual precipitation higher than 2062 mm,and the annual average temperature lower than 16.2℃.The number of diseased plants of pine wood nematode disease was positively correlated with altitude and annual precipitation,and was negatively correlated with annual average temperature.The number of worms and wormholes in pine wood nematode infected wood was very small at different altitudes,stump heights and stump diameters.[Conclusions]The pine wood nematode infected wood can be differentially processed after stump treatment,and stumps can be peeled.The results will provide a theoretical and practical basis for differentiated prevention and control of pine wood nematode disease in the future.

Pine wilt disease: a short review of worldwide research

This article summarizes the results of the research papers presented at the International Symposium on pine wilt disease （IUFRO Working Party Meeting 4.04.03） held in July 2009, at Nanjing, China. The general topics covered were on pine wilt disease （PWD）, its causal organism, the pinewood nematode （PWN） Bursaphelenchus xylophilus, plus other PWN-associated microorganisms that play a significant role in PWD such as bacteria （e.g. Pseudomonasfluorescens）. Most of the papers that are reviewed are based on work on PWD-PWN in East Asia and Russia. Specific topics covered include： 1） the fundamental conceptions of PWD development, 2） pathogenicity, 3） host-parasite relationships including the histopathology of diseased conifers and the role of toxins from bacteria-nematode ecto-symbionts, 4） PWN life cycle and transmission, 5） B. xylophilus dissemination models, 6） associations （with other nematodes）, 7） diagnostics, 8） quarantine and control of the PWN and 9） biocontrol of the PWN.

Investigation of beetle species that carry the pine wood nematode,Bursaphelenchus xylophilus(Steiner and Buhrer)Nickle,in China

In order to found new carriers of pine wood nematode(PWN),Bursaphelenchus xylophilus,beetles were collected from pine wilt disease-affected areas in six provinces in China.A total of 8830 beetles of 29 species was collected and examined to determine whether they were PWN carriers.Eight species were identified as carriers.Results included the first worldwide report of Monochamus uigromaculatus,Semanotus siuoauster,and Uraecha angusta being carriers of PWN,and the first report from China of A rhopalus rusticus carrying PWN.Monochamus alternatus was commonly collected in all six provinces and was the dominant species in four inland affected areas and A.rusticus was dominant in two coastal affected areas.The species varied between different neighboring regions in the same province.The distribution of the same species varied considerably over different regions.

Integrated management of African rice gall midge (AfRGM) (<i>Orseolia oryzivora,</i>Harris and gagné), weeds and diseases of lowland rice

Studies were conducted during the 2001 and 2002 cropping years at Edozhigi and Sachi in the Southern Guinea Savannah of Nigeria to study the effect of following rice with another crop on the next rice crop. There were twelve treatments consisting of poor, good and excellent weed management and pesticidal applications against (AfRGM and diseases set up in a randomized complete block design, in twelve plots in 3 replicates. Results showed that rice treated with gramular isazofos at 0.75 kg a.i. ha–1 and benomyl at 1.0 kg/ha at 20 and 40 days after transplanting (DAT), with good weed management and a follow up crop after rice reduced AfRGM occurrence and disease incidence with a consequent increase in yield of the next rice crop. In 2001 infestation of rice by ARGM was more at Sachi than Edozhigi, while in 2002 there was low ARGM occurrence at the two locations. Brown leaf spot was high at the two locations in the two years of the trial while leaf blast was checked by the integrated control methods used in the study. Higher yields were (1.7 - 11.9 t·ha) from treated-well weeded plots that were cropped to cowpea after the 2001 rice harvest Ludwigia decurens, Sphanoclea geylanica Cyperus difformis and Lepllocidia chinensis were the widely occurring weed species at Edozhigi site while Cyperus difformis, Ipomea mvolucrata, F. awuata and Firnbristylis litoralis were weed species prevalent at Sachi site. The rice nematode, hirschmanniella sp. was recorded at the Sachi site along with other nematodes but was absent at the Edozhigi site. The net benefit farmers would derive for following this rice-dry-season crop sequence vary from US$ 172 - 427 and US$ 175 - 265 ha–1 at Sachi and Edozhigi respectively.

Policy stakeholder perspectives on barriers and facilitators to launching a community-wide mass drug administration program for soil-transmitted helminths

Background:Recent evidence suggests that soil-transmitted helminth(STH)transmission interruption may be feasible through community-wide mass drug administration(cMDA)that deworms community members of all ages.A change from school-based deworming to cMDA will require reconfiguring of STH programs in endemic countries.We conducted formative qualitative research in Benin,India,and Malawi to identify barriers and facilitators to successfully launching a cMDA program from the policy-stakeholder perspective.Methods:We conducted 40 key informant interviews with policy stakeholders identified as critical change agents at national,state/district,and sub-district levels.Participants included World Health Organization country office staff,implementing partners,and national and sub-national government officials.We used the Consolidated Framework for Implementation Research to guide data collection,coding,and analysis.Heat maps were used to organize coded data and differentiate perceived facilitators and barriers to launching cMDA by stakeholder.Results:Key facilitators to launching a cMDA program included availability of high-quality,tailored sensitization materials,and human and material resources that could be leveraged from previous MDA campaigns.Key barriers included the potential to overburden existing health workers,uncertainty of external funding to sustain a cMDA program,and concerns about weak intragovernmental coordination to implement cMDA.Cross-cutting themes included the need for rigorous trial evidence on STH transmission interruption to gain confidence in cMDA,and implemen-tation evidence to effectively operationalize cMDA.Importantly,if policy stakeholders anticipate a cMDA program cannot be sustained due to cost and human resource barriers in the long term they may be less likely to support the launch of a program in the short term.Conclusions:Overall,policy stakeholders were optimistic about implementing cMDA primarily because they believe that the tools necessary to successfully implement cMDA are already available.Policy stakeholders in this study were cautiously optimistic about launching cMDA to achieve STH transmission interruption and believe that it is feasible to implement.However,launching cMDA as an alternative policy to school-based deworming will require addressing key resource and evidence barriers.

Microbial inoculants and garbage fermentation liquid reduced root-knot nematode disease and As uptake in Panax quinquefolium cultivation by modulating rhizosphere microbiota community

Objective:To find a suitable ecological cultivation measure to solve the problem of root-knot nematode disease of Panax quinquefolium(Panacis Quinquefolii Radix)and the heavy metals accumulating in its roots.Methods:Three-year-old P.quinquefolium was treated with four different combinations of microbial inoculant(MI)and garbage fermentation liquid(GFL)[the joint application of‘TuXiu’MI and Fifty potassium MI(TF),the combination use of‘No.1'MI and Fifty potassium MI(NF),‘Gulefeng’poly-γ-glutamic acid MI(PGA),GFL],and the untreated control(CK).Here,high-throughput sequencing,ICP-MS and UPLC were employed to systematically characterize changes of microbial diversity and structure composition,heavy metals(As,Cd and Pb)content and ginsenoside content among different treatments.Results:The results revealed that different MIs and GFL could increase the root dry weight of P.quinquefolium,PGA enhanced it by 83.24%,followed by GFL(49.93%),meanwhile,PGA and GFL were able to lessen root-knot nematode disease incidence by 57.25%and 64.35%.The treatment of PGA and GFL can also effectively reduce heavy metals in roots.The As content in GFL and PGA was decreased by 52.17%and 43.48%respectively,while the Cd and Pb contents of GFL and PGA was decreased somewhat.Additionally,the content of total ginsenosides was increased by 42.14%and 42.07%,in response to TF and NF,respectively.Our metagenomic analysis showed that the relative abundance of particular soil microbial community members related to the biocontrol of root-knot nematode disease and plant pathogen(i.e.,Chaetomium in NF,Xylari in GFL,and Microascus in PGA),heavy metal bioremediation(Hyphomacrobium in PGA and Xylaria in GFL),and nitrogen fixation(Nordella and Nitrospira in TF)was significantly increased;notably,potential harmful microflora,such as Plectosaphaerella and Rhizobacter,were more abundant in the control group.Conclusion:MI and GFL could improve the quality of P.quinquefolium by modifying its rhizosphere microbial community structure and composition,both of them are beneficial to the development of ecological cultivation of P.quinquefolium.

Ancylostoma ceylanicum and other zoonotic canine hookworms:neglected public and animal health risks in the Asia-Pacific region

Zoonotic hookworm infections remain a significant public health problem,causing nearly 500 milion cases globally and approximately four million disability-adjusted life years lost annually.More than one-fth of these cases are attrib-uted to Ancylostoma ceylanicum,an emerging zoonotic health issue in the Asia-Pacific region.This review presents key research gaps regarding the epidemiology,diagnosis,control,prevention and elimination of A.ceylanicum and other canine zoonotic hookworms as neglected health threats.A.ceylanicum is the second most prevalent human hook-worm in the region;it is the most common hookworm among dogs and cats-reservoirs of zoonotic infections.Previous population genetic and phylogenetic analyses revealed that A.ceylanicum has three possible transmis-sion dynamics:zoonotic,animal-only,and human-only pathways.The actual burden of zoonotic ancylostomiasis in most endemic countries remains unknown due to the use of parasitological techniques(e.g.,Kato-Katz thick smear and floatation techniques)that have reduced diagnostic performance and do not allow accurate species identifica-tion in helminth surveys.The emergence of benzimidazole resistance in soil-transmitted helminths(STHs),includ-ing hookworms,is a concern due to the protracted implementation of mass drug administration(MDA).Resistance is conferred by single nucleotide polymorphisms(SNPs)that occur in theβ-tubulin isotype 1 gene.These mutations have been reported in drug-resistant A.caninum but have not been found in A.ceylanicum in the field.A.ceylanicum remains understudied in the Asia-Pacific region.The zoonotic nature of the parasite warrants investigation of its occur-rence in human and animal reservoir hosts to understand the dynamics of zoonotic transmission in different endemic foci.The detection of benzimidazole resistance-associated SNPs in zoonotic hookworms from Asia-Pacific countries has yet to be thoroughly explored.Considering the high level of hookworm endemicity in the region,the circulation of resistant isolates between humans and animals potentially presents a significant One Health threat that can under-mine current MDA and proposed animal deworming-based control efforts.
