<\/a>Application of molecular techniques in forest protection research<\/strong><\/p>\n

Molecular techniques are increasingly being improved, developed and applied in many fields of research. In the field of forestry, molecular techniques are widely to study plant genetic diversity, phylogeny, identification of microorganisms, molecular plant breeding, and selection of plant varieties with desirable growth characteristics such as wood density and fiber length. In the field of forest protection research, molecular techniques are valuable for detecting and identifying pests such as insects, nematodes, fungi and bacteria which are harmful to forest trees. The technology also has applications for selecting resistant trees as well as biocontrol agents. This review introduces molecular techniques and their applications in the field of forest protection research.<\/p>\n

<\/a>New records of stem borer species damaging eucalyptus plantations in Northern Vietnam<\/strong><\/p>\n

Eucalyptus<\/em> is widely planted in Vietnam because is grows fast, can be harvested after short rotations, and the wood has high economic value. A number of species and hybrids are highly adapted to climatic and soil characteristics in the Northern Vietnam. In recent years, plantation areas in some provinces have been severely attacked by stem-boring insects, resulting in economic loss of foresters. This paper aims to provide information regarding the identification, morphological description, and damage symptoms of Batocera lineolata<\/em>, Zeuzera multistrigata<\/em>, Endoclita salvazi<\/em> and Endoclita <\/em>sp. in eucalyptus plantations in Lao Cai, Lang Son, Quang Ninh, Bac Giang, Phu Tho, Tuyen Quang, and Hoa Binh provinces. Among these four insect pests, B. lineolata<\/em> and Endoclita <\/em>sp. are the most serious stem borer pests causing heavy damage to Eucalyptus<\/em> hybrids at the age of 1 – 3 years. In order to effectively manage these stem borers, further studies on their biology and ecology are needed.<\/p>\n

<\/a>Ambrosia beetles: A threat to forest trees in Vietnam and management<\/strong><\/p>\n

Forest trees in Vietnam are increasingly attacked by ambrosia beetles (Coleoptera: Curculionidae: Scolytinae). This paper aims to synthesize published studies concerning ambrosia beetles which have been recognized to be severe borers of forest trees in the country. There are twelve species of ambrosia beetles attacking Acacia mangium<\/em>, A<\/em>. auriculiformis<\/em>, A<\/em>. hybrid, Dalbergia tonkinensis<\/em>, Cinnamomum cassia<\/em>, Erythrophleum fordii<\/em>, Eucalyptus urophylla<\/em>, and Pinus massoniana<\/em>. Of these 12 ambrosia beetles, five have been identified as Euwallacea fornicatus<\/em>, Ips calligraphus<\/em>, Xyleborinus artestriatus<\/em>, Xyleborus perforans<\/em>, and Xylosandrus crassiuculus<\/em>. The seven unknown species are Euwallacea<\/em> sp.1, Euwallacea<\/em> sp.2, Euwallacea<\/em> sp.3, Xylosandrus<\/em> sp.1, Xylosandrus<\/em> sp.2, Ips<\/em> sp., and Dendroctonus<\/em> sp. In addition, the present paper summarizes the related studies on control measures for these ambrosia beetles in Vietnam.<\/p>\n

<\/a>The insect pests of Melaleuca leucadendra<\/em> and M. cajuputi<\/em> plantations in Southwest of Vietnam<\/p>\n

Insect pests associated with 3 – year-old plantations of Melaleuca leucadendra<\/em> in Kien Giang and Ca Mau provinces, and M. cajuputi<\/em> in Long An and Dong Thap provinces comprise 32 species, belonging to 22 families, and 4 orders. There are twenty species of Lepidoptera, seven species of Homoptera, three species of Coleoptera, and two species of Hemiptera. Survey results showed that the M. leucadendra<\/em> plantations were attacked by insect pests with average damage incidence P = 2.5 – 65.2% and average damage index R = 0.03 – 2.10. For M. cajuputi<\/em> plantations, the average damage incidence was P = 2.5 – 24.5% and the damage index was R = 0.03 – 0.35. Of the 32 species recorded, Targalla delatrix<\/em> (Lepidoptera: Euteliidae) and Neurozerra conferta<\/em> (Lepidoptera: Cossidae) caused severe damage of M. leucadendra<\/em> plantations with hight damage indexes of R= 2.10 and 2.03, respectively.<\/p>\n

<\/a>The insect pests of Illicium verum <\/em>Hook. f. in Northeast of Vietnam<\/strong><\/p>\n

Illicium verum<\/em> Hook. f. (star anise) is a specialty tree with high economic value that plays an important role in socio-economic development, hunger eradication and poverty alleviation of ethnic minorities in the Northeast region of Vietnam. The plantation area in Vietnam is currently about 60,000 ha, concentrated mainly in the Northeast region. In recent years, pests affecting the growth, development and yield of I. verum <\/em>have been observed. Surveys of the I. verum<\/em> pest species in Lang Son and Bac Kan provinces revealed 43 species belonging to 31 families and 6 orders. Lepidoptera had the largest number of species with 17 species belonging to 10 families followed by Coleoptera with 11 species belonging to 7 families. The remaining pests were Homoptera with 9 species belonging to 8 families, Hemiptera with 4 species belonging to 4 families, and Isoptera and Phasmida each with 1 species. The average damage incidence of the pests ranged from 6.9 – 53.6% and average damage index from 0.06 to 2.26. Oides duporti<\/em> (Coleoptera: Chrysomelidae) and Pogonopygia nigralbata <\/em>(Lepidoptera: Geometridae) caused the most severe damage and their spread is a concern to producers. Therefore, it is necessary to conduct studies on biological characteristics and control measures to effectively manage these pests.<\/p>\n

<\/a>Potential application of plant-derived volatiles for screening forest tree resistan to ambrosia beetles<\/strong><\/p>\n

Ambrosia beetles are among the most dangerous groups of wood-boring beetles in forests around the world. Major forest tree species in Vietnam are being damaged by ambrosia beetles with severity increasing over recent years. These beetles often bore entry holes on the trunk and branch of host trees where they then inoculate fungal pathogens that cause mass mortality of forest trees. Research on the behavioral mechanism by which ambrosia beetles find and select suitable host trees in a mixed forest is of interest to scientists. Many volatile substances have been identified, synthetized, and used widely in ambrosia beetle management programs. The main aims of this paper are to appraise published papers regarding plant-derived volatiles, and to evaluate their roles in the control of ambrosia beetles. In addition, the paper analyzes opportunities for screening forest trees tolerant to ambrosia beetles based on plant-derived volatiles. The information gathered in this paper will contribute to the effective management of ambrosia beetles in Vietnam.<\/p>\n

<\/a>Heart rot disease and screening of disease resistance in Acacia mangium<\/em><\/strong><\/p>\n

The area of Acacia plantations in Vietnam has increased rapidly in recent years reaching about 2 million ha in 2020. For the purpose of afforestation for timber, Acacia mangium<\/em> is commonly planted in some ecological regions. However, A. mangium<\/em> plantations have been attacked by heart rot fungi, causing a serious decline in productivity and wood quality. This study aimed to evaluate the pathogenicity of 27 isolates of heart rot fungi and to screen the tolerance of 90 A. mangium<\/em> families by artificial inoculation on 1.5 year-old plants. The results of the pathogenicity test showed that 14 isolates had very strong pathogenicity with all trees infected and long lesions (20.13 – 24.33 cm). There was a significant difference between families in the mean lesion length on the stems. The resistance of 90
\nA. mangium<\/em> families was divided into three groups including very strong (16 families), strong (50 families) and moderate (24 families). Families with strong and very strong resistance are promising material for Acacia<\/em> mangium<\/em> breeding programs in Vietnam.<\/p>\n

<\/a>Curent status of leaf blight, leaf spot and shoot blight of Eucalyptus<\/em> clones in Phu Tho province<\/strong><\/p>\n

Eucalyptus<\/em> species are one of the primary forest plantation species for economic development in Phu Tho province. Recently, leaf blight, leaf spot and shoot blight caused by the fungal pathogens Cylindrocladium quinqueseptatum <\/em>and Cryptosporiopsis eucalypti<\/em> severely damaged Eucalyptus<\/em> plantations in Phu Ninh, Yen Lap and Tan Son districts in Phu Tho province. The aim of this study was to investigate and evaluate the disease status of Eucalyptus<\/em> clones being grown in Phu Tho province. The results revealed that 16 out of 18 Eucalyptus<\/em> clones from the age of 2 were infected by leaf blight, leaf spot and shoot blight diseases. Clones PN14 and U6 had the worst growth rate and the most severe disease. The disease incidence (P%) of PN14 was 100% in sites across three districts and the disease index (R) ranged from 2 – 4; the disease incidence of 3 – year-old U6 planted at Phu Ninh district was 100% and R was very severe, up to 3.86. Four clones had moderate disease status and 10 clones had light disease status. A significant finding was that two-year-old TTKT7 clone planted at Bao Thanh and four-year-old PN10 clone planted in Tram Than communes in Phu Ninh district were not affected by the diseases.<\/p>\n

<\/a>Diseases of Illicium verum<\/em> Hook. f. in Lang Son and Bac Kan provinces<\/strong><\/p>\n

Star anise (Illicium verum<\/em> Hook. f.) is a multi-purpose tree that is widely cultivated in Vietnam. The star anise tree has significant economic value, and its products are a substantial source of export revenue. In addition, star anise is crucial for preserving the environment’s ecological balance. However, star anise plantations have been severely damaged by a number of diseases, impacting their productivity and the local economy. Therefore, research on pathogens of star anise is a crucial and urgent task and provides a foundation for future studies on disease management. This study aims to identify potential causal agents of disease in star anise planted in Lang Son and Bac Kan provinces. Fungal pathogens isolated were Neofusicoccum parvum,<\/em> Phyllosticta<\/em> sp., Aureobasidium melanogenum, <\/em>Peronospora<\/em> sp., Diaporthe <\/em>amygdali, Colletotrichum fructicola<\/em>, Colletotrichum gloeosporioides, Colletotrichum horii<\/em>, Fusarium oxysporum, <\/em>Alternaria<\/em> sp., Pestalotiopsis maculans<\/em>, Xylaria laevis<\/em>, Dichomitus squalens<\/em> and Cephaleuros virescens<\/em>. The average disease incidence and disease index ranged from 2.2 to 65.1% and 0.10 to 2.13, respectively. Colletotrichum gloeosporioides<\/em> was identified as the agent responsible for leaf and fruit anthracnose, causing significant damage in star anise plantations in Lang Son and Bac Kan provinces.<\/p>\n

<\/a>Disease of Docynia indica <\/em>planted in the Northwest of Vietnam<\/strong><\/p>\n

Docynia indica <\/em>(sontra is planted in the Northwestern provinces, with an estimated area of over 15,000 hectares by 2020. A disease survey was undertaken in 2019 – 2020 to determine the occurrence of diseases on leaves, fruits, stems and roots affecting the yield and quality of D. indica<\/em> fruit. This study assessed the incidence and severity of disease and identified any associated pathogen fungi on D. indica<\/em> in the Northwestern region. Based on morphological and molecular identification, 15 species of pathogenic fungi were identified belonging to 10 families and 8 orders. Fruit rot caused by Colletotrichum siamensis<\/em> was the disease of greatest concern (P = 41.2%; R = 1.12). This study provides a basis for monitoring newly emerging diseases and proposing solutions for effective disease management of sontra in Vietnam.<\/p>\n

<\/a>Expanding trials for Acacia<\/em> and Eucalyptus<\/em> clones in five ecological regions in Vietnam<\/strong><\/p>\n

The inclusion of new Acacia<\/em> and Eucalyptus<\/em> clones in large-scale afforestation programs in Vietnam should be underpinned by field evaluation trials in the major ecological regions. This paper reports on the findings of these extensive trials. Acacia auriculiformis<\/em> clones AA1 and AA9 grew well in Ca Mau and Yen Bai provinces, and yields exceeded
\n20 m3<\/sup>\/ha\/year. Acacia<\/em> hybrid clones AH1 and AH7 grew well in all trials, and yields outperformed the other clones and the control reaching 25.3 – 40.8 m3<\/sup>\/ha\/year. These Acacia<\/em> clones had no symptoms of pink disease or Ceratocystis<\/em> wilt disease. Eucalyptus urophylla<\/em> clones PN10 and PN108 grew well in Thanh Hoa province with yields of 20.0 – 22.7 m3<\/sup>\/ha\/year; clones PN21, PN108 and PN3D grew well in Yen Bai province with yields of 22.5 – 29.3 m3<\/sup>\/ha\/year; clones PN21, PN46, PN47 and PN108 grew well in Hoa Binh province with yields of 22.2 – 31.2 m3<\/sup>\/ha\/year; and clones PN21 and PN108 had good growth performance in Dak Nong province with yield over 18 m3<\/sup>\/ha\/year. These eucalyptus clones exhibited strong disease resistance. It is recommended that these Acacia<\/em> and Eucalyptus<\/em> clones be considered for afforestation in the relevant ecological regions in Vietnam.<\/p>\n

<\/a>Selection of plus trees of Illicium verum<\/em> Hook. f. with high fruit yield and resistance to insect pests and disease in Lang Son province<\/strong><\/p>\n

Star anise (Illicium verum<\/em> Hook. f.) is a non-timber forest product which has high economic and medicinal values. The total cultivated area of star anise in Vietnam is about 60,000 ha, and it is primarily distributed in Lang Son, Bac Kan and Quang Ninh provinces. In the present study, a series of laboratory experiments were carried out to evaluate the resistance of
\nI. verum<\/em> to insect pests and disease and to quantify their essential oil composition and anethole content. The research was undertaken on 100 star anise trees which had been proven to produce high yields of fruits in seven stands belonging to different communes of Van Quan district in Lang Son province. As a result, 66 star anise individuals in Yen Phuc and Binh Phuc were recognized to be plus trees (Decision number 432\/Q\u0110 SNN dated 30\/11\/2021). Fruit yields obtained from the 66 plus trees were 30% higher (>32.5 kg\/crop\/year) than those obtained from the stand average; the plus trees showed strong resistance to damage from insect pests and pathogen; and oil production of the plus trees was at least 15% higher than the stand average. The yields of essential oils and anethole obtained from dried fruits were 9.85 – 11.63% and 95 – 97%, respectively. These findings will play important roles in the selection and improvement of star anise in the province.<\/p>\n

<\/a>Screening bacterial strains from Pinus<\/em> forest soil in Yen Dung district, Bac Giang province for their ability to solubilize insoluble inorganic phosphorus<\/strong><\/p>\n

Pinus caribaea<\/em> is one of the potential and promising forest plantation species for economic, enviromental and landscape development for Bac Giang province in general and for Yen Dung district in particular. However, the land for planting pine forests in Yen Dung is mainly degraded and poor nutrient. This study aimed to isolate and select bacterial strains capable of solubilizing insoluble inorganic phosphorus compounds from local soil samples so that they can be used as local beneficial microorganisms for producing biofertilizers to improve soil nutrient availability on degraded sites. Eight bacterial strains with phosphate solubilization capacity were isolated from Pinus<\/em> forest soil in Yen Dung district, Bac Giang province. Their efficiencies in solubilizing insoluble inorganic phosphorus significantly differed in Pikovskaya plate assay with and without agar. The identified bacterial strain Paraburkholderia tropica<\/em> BG8 had the most phosphate solubilizing capacity with the diameter of the phosphorus-dissolving ring on Pikovskaya agar medium reaching 17.1 mm and the phosphorus degraded on Pikovskaya without agar medium reaching 15.3 mg\/L. This bacterial isolate has potential for producing microbial products and microbial organic fertilizers that can be used in order to improve infertile soil and increase plant growth.<\/p>\n

<\/a>Artificial cultivation of Ganoderma lucidum<\/em> on Acacia<\/em> sawdust<\/strong><\/p>\n

Acacia<\/em> sawdust is a low-cost and readily available material for the cultivation of Ganoderma lucidum<\/em>, a valuable edible and medicinal mushroom. In order to ensure productivity and save production costs, research was undertaken to assess the suitability of acacia sawdust to replace the traditional raw materials being used in G. lucidum<\/em> production in Vietnam. The results showed that G. lucidum<\/em> grew best at 25 – 30o<\/sup>C and 80 – 90% humidity. The mix of 89% acacia sawdust +1% powdered CaCO3<\/sub> + 10% rice bran gave the fastest growth in a closed fiber system (26.1 days) and yield reached 98.26 g fresh (32.98 g dry weight) after 2 harvests.<\/p>\n
