14. Fontes de matéria orgânica e seus efeitos na severidade da murcha-de-fusário do caupi
Cowpea (Vigna unguigulata) is one of the most important crops in North and Northeast Brazil, posing an important socioeconomic role for many small and medium-size farms in these regions. The Fusarium wilt caused by Fusarium oxysporum f. sp. tracheiphilum is a major disease for cowpea crops grown in Northeast Brazil. Thus, the work was carried out to evaluate

15. Biogeography and evolution of Amazonian triatomines (Heteroptera: Reduviidae): implications for Chagas disease surveillance in humid forest ecoregions
An ecological-evolutionary classification of Amazonian triatomines is proposed based on a revision of their main contemporary biogeographical patterns. Truly Amazonian triatomines include the Rhodniini, the Cavernicolini, and perhaps Eratyrus and some Bolboderini. The tribe Rhodniini comprises two major lineages (pictipes and robustus). The former gave rise

16. Artificial infestation of Boophilus microplus in beef cattle heifers of four genetic groups
Resistance of beef cattle heifers to the cattle tick Boophilus microplus was evaluated by artificial infestation of 66 beef cattle heifers of the following genetic groups: 16 Nelore (NE), 18 Canchim x Nelore (CN), 16 Angus x Nelore (AN) and 16 Simmental x Nelore (SN). The animals, with a mean age of 16.5 months, were maintained with no chemical tick control

17. Environmental management for the control of Triatoma dimidiata (Latreille, 1811), (Hemiptera: Reduviidae) in Costa Rica: a pilot project
An ecological control method, using environmental management operations, based on biological and behavioral characteristics of Triatoma dimidiata (Latreille, 1811), was implemented as a pilot project in an area of Costa Rica where the bug is prevalent. The sample was represented by 20 houses with peridomestic colonies (two also had indoor infestation), divid

18. Aspects of peridomiciliary ecotopes in rural areas of Northeastern Brazil associated to triatomine (Hemiptera, Reduviidae) infestation, vectors of Chagas disease
Artificial ecotopes of 121 peridomiciliary environments in four rural localities in the state of Ceará, Brazil, were studied and the type of material of the ecotopes was identified as triatomine infestation. Two thousand two hundred and four Triatoma brasiliensis Neiva, 340 Triatoma pseudomaculata Corrêa and Espínola, 121 Rhodnius nasutus Stall, and 5 Pan

19. Biologia e ecologia de Pleuroptya silicalis (Lepidoptera: Crambidae) e Urbanus esmeraldus (Lepidoptera: Hesperiidae): taticas defensivas e interações com formigas em arbustos de Urera baccifera (Urticaceae) / Biology and ecology of Pleuroptya silicalis (Lepidoptera: Crambidae) and Urbanus esmeraldus (Lepidoptera: Hesperiidae): defence tactics and interactions with ants on shrubs of Urera baccifera (Urticaceae)
1. This work investigates the biology and behaviour of two lepidopteran species that feed on the nettle Urera baccifera (Urticaceae). The plant is visited by 22 ant species, which are attracted by the nettle s fleshy fruits and pearl bodies. Larvae of both species build leaf shelters: Pleuroptya silicalis (Crambidae: Pyraustinae) makes leaf rolls, and Urbanu

20. Genome scan for QTL related to bovine resistance to Boophilus microplus / Varredura genômica para QTL associados à resistência a Boophilus microplus em bovinos
In tropical countries losses caused by bovine tick infestation have a tremendous economic impact on production systems. Genetic variation between Bos taurus and Bos indicus to tick resistance and molecular biology tools might facilitate the use of molecular markers linked to resistance traits as an auxiliary tool in selection programs. The objective of this

21. Aspects of the infestation of Culex (Culex) quinquefasciatus (Diptera: Culicidae) in the Pinheiros river, São Paulo (São Paulo, Brazil) and considerations on the applications of the population control / Aspectos da infestação de Culex (Culex) quinquefasciatus (Diptera: Culicidae) no rio Pinheiros, São Paulo (São Paulo, Brasil) e considerações sobre as aplicações de controle da população
Objetivo. O estudo apresenta aspectos da biologia e ecologia de Culex quinquefasciatus no rio Pinheiros, e focaliza alguns possíveis fatores que levam o mosquito proliferar neste ambiente. As análises das informações permitiram conhecer aspectos da infestação da espécie e a eficácia das ações de controle efetuadas no local. Métodos. O trabalho de

22. Infestation of beef cattle females by Rhipicephalus (Boophilus) microplus, Haematobia irritans e Dermoatobia hominis. / Estudo da infestação de fêmeas bovinas de corte pelo Rhipichepalus (Boophilus) microplus, Haematobia irritans e Dermatobia hominis.
Em regiões de clima tropical, a resistência dos bovinos a ectoparasitas é fator importante na determinação da eficiência dos sistemas de produção. Os objetivos neste trabalho foram avaliar o grau de resistência de fêmeas Nelore (NE) e cruzadas Canchim x Nelore (CN), Aberdeen Angus x Nelore (AN) e Simental x Nelore (SN) de diversas idades ao carrapa

24. Biological and mannering studies of Migdolus fryanus (Westood, 1863) (Coleoptera: vesperidade) and its interaction with entomopathogenic nematodes and other agents of mortalities / Estudos biologicos e comportamentais de Migdolus fryanus (Westwood, 1863) (Coleoptera : vesperidae) e sua interação com nematoides entomopatogenicos, e outros agentes de mortalidade
During de present study biological and morphological data of Migdolus fiyanus (Westwood, 1863) (Coleoptera: V esperidae) were obtained. Males and females after mating were collected in sugar cane field and brought to the laboratory for morphological and biological investigations. Females were individualized in plastic containers ( 20 L). The dimensions were
