13. Supplanting resistance of the Mi gene by root-knot nematode in industrial tomato in the Cerrado in Goiás State of Brazil
RESUMO: Problemas causados pelos nematoides-das-galhas, pertencentes ao gênero Meloidogyne podem ser controlados com a introdução de genes de resistência em cultivares comerciais de tomateiro. No entanto, plantas do híbrido ‘Heinz 9992’ adequadas ao processamento industrial, portadoras do gene Mi, foram encontradas com suas raízes severamente infe

14. Bioassay Technique and Maintenance of Gyropsylla spegazziniana (Lizer, 1719) (Hemiptera: Psylloidea: Aphalaridae) in vitro Conditions
ABSTRACT Gyropsylla spegazziniana is one of the most important pest of yerba mate by sap-sucking that lead to leaves deformation and there are no insecticides registered for its control. The present study describes a new technique to be used in bioassays with the insect. Galls were collected from infested yerba mate plants. In the laboratory, the galls were

15. Distribution of gall-inducing arthropods in areas of deciduous seasonal forest of Parque da Sapucaia (Montes Claros, MG, Brazil): effects of anthropization, vegetation structure and seasonality
Abstract In the present study, we inventoried gall-inducing arthropod species and evaluated the effects of habitat anthropization, vegetation structure and seasonality on this group in areas of deciduous seasonal forest of Parque da Sapucaia, Montes Claros, MG, Brazil. The gall-inducing fauna was sampled between April 2017 and February 2018 from 20 plots dis

16. Search for sources of resistance to Meloidogyne enterolobii in commercial and wild tomatoes
RESUMO Meloidogyne enterolobii (=M. mayaguensis) é um patógeno de plantas capaz de induzir galhas e reduzir produtividade de uma vasta gama de espécies hospedeiras. Este patógeno tem sido também reportado como ameaça global para a cultura do tomateiro (Solanum lycopersicum), principalmente, por causa da sua habilidade de suplantar a resistência a algu

17. Ant fauna associated with Microgramma squamulosa (Kaulf.) de la Sota (Polypodiaceae) fern galls
Abstract Galls are neoformed plant structures created by cell hyperplasia and hypertrophy induced by a number of organisms, especially insects. After adult insects hatch, senescent galls may remain on the host plant and be occupied by a succession of fauna, the most important and dominant being ants. This study aimed at characterizing the ant fauna successor

18. A new species of Youngomyia Felt from Brazil and new morphological data on Youngomyia pouteriae Maia (Insecta, Diptera, Cecidomyiidae)
Abstract Youngomyia matogrossensis Proença & Maia a new species of Cecidomyiidae (Insecta: Diptera) that induces cylindrical hairy galls on leaves of Pouteria torta (Mart.) Radlk. (Sapotaceae) is herein described and illustrated (larvae, pupal exuviae, male and female). The galler, gall and host plant were collected at Parque Nacional da Chapada dos Guimar�

19. O vigor da planta altera a densidade de galhas em populações de Baccharis longiattenuata (Asteraceae) sob distintas condições de solo?
Resumo A hipótese do vigor da planta sugere que plantas mais vigorosas suportam maior densidade de galhas. Este estudo avaliou tal hipótese utilizando o sistema ácaro-Baccharis longiattenuata em duas populações de restinga sob condições ambientais distintas. As medidas de vigor incluíram: altura e diâmetro do caule, volume e área da copa, número d

20. A new species of Clinodiplosis (Diptera: Cecidomyiidae) causing galls on Banisteriopsis membranifolia (Malpighiaceae), an endemic plant in Brazil
ABSTRACT Clinodiplosis quartelensis sp. nov. (holotype male in MNRJ: Brazil, Minas Gerais State), a new gall midge species causing leaf galls on Banisteriopsis membranifolia (A. Juss.) B. Gates (Malpighiaceae), an endemic liana in Brazil, is described based on larva, pupa, adult male and female and its gall is characterized. Galls were collected in Quartel d

22. Reaction of wild Solanaceae rootstocks to the parasitism of (Meloidogyne javanica)
RESUMO A produção intensiva de hortaliças em ambiente protegido pode aumentar a quantidade de inóculo de patógenos habitantes do solo, a exemplo dos nematoides das galhas. Dessa forma, objetivou-se avaliar o potencial de solanáceas como porta-enxertos resistentes ao nematoide Meloidogyne javanica como alternativa à enxertia em tomateiro. O experimento

23. Characterization of insect galls from a vegetation area in Altinópolis, São Paulo State, Brazil
Abstract Herein, we studied the occurrence of insect galls from natural vegetation around the Itambé Cave, Altinópolis, SP, Brazil. A sampling effort of 7.5 hours resulted in 41 gall morphotypes on 21 host plant species from 14 families. The richest families of host plants in morphotypes were Fabaceae (N = 11), Euphorbiaceae (N = 7), and Malpighiaceae (N =

Abstract A new species, Asphondylia cipo sp. nov. (Diptera: Cecidomyiidae) causing stem and petiole galls on Lessingianthus warmingianus (Baker) H. Rob. (Asteraceae) is described and illustrated from Serra do Cipó, Minas Gerais State, Brazil. A key is provided to separate species of this genus associated with host plants in the Asteraceae family from the Ne
