Lingren","doi":"10.57182/jbiopestic.9.2.220-227","DOIUrl":"https://doi.org/10.57182/jbiopestic.9.2.220-227","url":null,"abstract":"Oriental fruit moth (OFM), Cydia molesta (Busck) (Lepidoptera: Tortricidae) and peach twig borer (PTB) Anarsia lineatella (Zell) (Lepidoptera: Gelechiidae) are economically important pests of peach, nectarine and apricot in Bulgaria. Their larvae cause damage, infesting shoots and fruits. Investigations were carried out in two fruit-bearing commercial peach orchards in South-East Bulgaria in the Sliven district during the period 2014 -2016. The aim of this study was to test the effectiveness of mating disruption (MD) in control of pests in peach orchards, using CIDETRAK® OFM (Oriental Fruit Moth)/ PTB (peach twig borer) and CIDETRAK® OFM/PTB MESO dispensers. The damage to shoots was evaluated during the first generation of OFM and PTB on 20 trees, randomly selected within the central area of each block. Correspondingly, fruit damage was recorded on 100 fruits per each selected tree; so, 2000 fruits were inspected for damage from both pests in each block. The rate of damaged fruits in the trial plots were compared with that in the reference orchard, located in the vicinity, treated with conventional pesticides. CIDETRAK® OFM/PTB (@400 dispensers/ha) and CIDETRAK® OFM/PTB MESO (@80 and 20 dispensers/ha) completely inhibited C. molesta in the pheromone traps installed in the trial plots, indicating a high level of disruption. The percentage of shoots infested by OFM and PTB larvae was 0% in the MD plots, and the damage rate to fruits was rather low (>1%). The present results do confirm that mating disruption, using CIDETRAK® OFM/PTB and CIDETRAK® OFM/PTB MESO dispensers, can provide a more effective control of both important pests on peach - oriental fruit moth and peach twig borer. The use rate of CIDETRAK® OFM/PTB and CIDETRAK® OFM/PTB MESO dispensers shows that the reduced rate of dispensers does not affect the effectiveness of mating disruption and will help the growers to decrease labour in the field. Applications of these dispensers can provide effective control of oriental fruit moth and peach twig borer, than the conventional protection programmes employed in Bulgaria. This approach to controlling oriental fruit moth and peach twig borer is in line with the recent EU recommendations that emphasize the preservation of the natural environment and production of healthy fruits, with no pesticide residues","PeriodicalId":15069,"journal":{"name":"journal of biopesticides","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71088628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most common plant pathogenic fungi which cause severe diseases to economic crops in Thailand are Lasiodiplodia theobromae, Sclerotium rolfsii, Phytophthora palmivora, Colletotrichum capsici, Pyricularia grisea, Alternaria sp., Helminthosporium maydis, Rhizoctonia solani, Fusarium oxysporum and Colletotrichum gloeosporioides. Control of these pathogens is carries out through the use of synthetic fungicides which are harmful to environment. This study aims to at investigating the efficacy of the ethyl acetate crude extracts of the cultures Talaromyces flavus Bodhi003, NeosartoryafischeriBodhi004 and Eurotium sp. Bodhi005 isolated from riparian forest soils to inhibit the mycelial growth of ten plant pathogenic fungi in in vitro conditions at various concentrations. At the highest concentrations (10,000 ppm), all crude extracts exhibited a complete mycelial growth inhibition of some plant pathogenic fungi when compared with the water control. Interestingly, Eurotium sp. Bodhi005 crude extract was recorded as having excellent inhibitory activity against S. rolfsii at 1,000 ppm concentration. Results from this study demonstrate that ethyl acetate crude extracts from T. flavus Bodhi003,N. fischeriBodhi004, and Eurotium sp. Bodhi005 could be used to control the mycelial growth of plant pathogenic fungi and allow researcher to identify new potential sources for the development of alternative biofungicide to reduce plant pathogenic fungi.","PeriodicalId":15069,"journal":{"name":"journal of biopesticides","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71088472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pathological changes in gills of exposed fishes include shrunken and fused gill lamellae, inflammatory cells in the primary and secondary gill lamellae. Exposed liver showed lesions consisting of vacuolar degeneration and disruption of hepatocytes. The changes found in intestine were vacuolar degeneration and disruption of epithelial cells of villi, ruptured and shapeless villi.

The production and productivity of the crop is greatly hampered by the fruit borer, Helicoverpa armigera (Hübner) which causes damage to the developing fruits and results in yield loss. The indiscriminate use of synthetic chemical pesticides to control this pest resulted in development of resistance and harmful pesticide residues in fruits. To avoid such problems caused due to indiscriminate use of insecticides, utilization of Host Plant Resistance (HPR) is an ecologically viable, alternate insect pest management strategy. The tomato accession Varushanadu Local along with a popular variety PKM1 was tested for induction of resistance by various microbial inoculants viz., Azospirillum, Phosphobacteria, Pseudomonas, K-solubilizer, Azospirillum + Phosphobacteria, Azospirillum + Pseudomonas, Azospirillum + K-solubilizer, Phosphobacteria + Pseudomonas, Phosphobacteria + K - solubilizer. and Pseudomonas. Based on the preliminary study, the promising microbial inoculants viz., Pseudomonas, K-solubilizer, Azospirillum, + k-solubilizer, pseudomonas + k-solubilizer, and phosphobacteria + Ksolubilizer were selected. Feeding preference of H. armigera to the leaves and fruits was the minimum towards the accessions Varushanadu Local treated with Pseudomonas + Ksolubilizer. Plants of the accessions Varushanadu Local supplied with Pseudomonas + Ksolubilizer exerted profound antibiosis effects against the life stages of H. armigera as evidenced by higher larval mortality, reduced pupation, reduced larval, pupal and adult duration.","PeriodicalId":15069,"journal":{"name":"journal of biopesticides","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71088340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
