1. Bell pepper rootstocks with multiple resistance to soilborne diseases
ABSTRACT Grafting has been increasingly used to overcome soilborne pathogens. The commercial rootstock hybrids AF-8253 (Sakata) and Fortaleza (Takii), as well as Embrapa’s new hybrid, BRS Acará, were evaluated as rootstocks for the bell pepper hybrids Margarita (Syngenta) and Pampa (Clause) as scions, under natural infestation of Ralstonia pseudosolanacea

2. Phytonematode population dynamics in common bean cultivation under crop rotation and no-tillage conditions
ABSTRACT Strategies for conserving natural resources and reducing agricultural inputs are the great challenge for agriculture, such as sustainable alternatives to control agricultural pests of high economic impact, e.g. plant-parasitic nematodes. This work aimed to evaluate phytonematode’s population dynamics in common bean cultivation grown under crop rot

3. MOTILITY AND MIGRATION OF NEMATODES IN SALINE ENVIRONMENTS
RESUMO - Os nematoides parasitas de plantas causam sérios prejuízos agrícolas no Nordeste brasileiro. Adicionalmente, a salinização do solo, especialmente na região semiárida do Nordeste é outro fator que limita a produtividade das culturas. Avaliou-se nesse estudo, a motilidade de Meloidogyne enterolobii e Pratylenchus coffeae, e, a migração verti

4. Nematological survey in coffee nursery in Espirito Santo state, Brazil
ABSTRACT Despite the important role of coffee production in the economy of Espirito Santo, the second largest coffee producing state in Brazil, productivity is still below the Brazilian average. One of the factors that explain this low productivity is the presence of nematodes of the genus Meloidogyne. Contaminated seedlings are an important and efficient ag

5. Response of grey slug to entomopathogenic nematodes
ABSTRACT Biological control using entomopathogenic nematodes (EPNs) is known as an ecofriendly strategy in integrated pest management. The terrestrial slug Parmacella ibera is a major pest of vegetables and citrus trees in north of Iran. The heavy costs and environmental concerns of synthetic molluscicides led the study to use EPNs, against the slug P. ibera

6. In vitro and in vivo control of yam dry rot nematodes using pyroligneous extracts from palm trees
ABSTRACT Dry rot of yam (Dioscorea spp.) caused by Scutellonema bradys and Pratylenchus spp. has restricted yam production in Brazil. Plant-based products can be useful reducing nematode damages. The objectives of this study were to evaluate the nematostatic and nematicidal in vitro activities of pyroligneous extracts from Cocos nucifera, Syagrus cearensis,

7. Synthesis and Evaluation of Nematicidal Activity of Compounds Derived from Norbornadiene
Nematode is a major problem in agriculture, the effective way to control this pest is through chemical control, but the efficient molecules present in the market have great toxicity to mammals and birds. Thus, there is a constant demand for the development of new nematicide molecules. This study describes the synthesis of 21 novel esters derived from norborn

8. Chitosan Nanoparticles Loaded with Carvacrol and Carvacryl Acetate for Improved Anthelmintic Activity
Carvacrol (CV) and carvacryl acetate (CVA) are bioactive compounds that have anthelmintic action and the nanoencapsulation may be an alternative to potentialize their efficacy. The aim of this work was to nanoencapsulate CV and CVA using chitosan/gums and evaluate cytotoxicity and the anthelmintic activity. A 24 factorial experimental design was performed to

9. Effects of entomopathogenic nematodes Steinernema carpocapsae and Heterorhabditis bacteriophora on the fitness of a Vip3A resistant subpopulation of Heliothis virescens (Noctuidae: Lepidoptera)
ABSTRACT The widespread use of transgenic plants imposes selection pressure on insect pest populations to develop insecticide resistance. Evaluation of effectiveness of resistance management strategies is very important in resistance management programs. Resistance management to insecticides is widely believed to depend in part on associated fitness costs. F

10. Automated Counting of Meloidogyne javanica Galls in Vegetable Roots
RESUMO Os nematoides-das-galhas, gênero Meloidogyne spp., estão entre os parasitas mais destrutivos das plantas cultivadas. O sintoma mais característico da doença é o surgimento de galhas no sistema radicular. O uso da resistência genética é um dos mais eficientes, econômicos e menos impactantes do ponto de vista ambiental no controle desse endopar

12. Stephanofilariasis in beef cattle - case report
RESUMO A estefanofilariose é uma dermatite ulcerativa causada por nematódeos que acometem bovinos em vários países do mundo, no entanto não tem sido descrita em bovinos de corte no Brasil. O objetivo do trabalho é a descrição de três casos de estefanofilariose em vacas de corte ocorridos no município de Ipê, RS. A enfermidade foi caracterizada por
