13. Biologia e comportamento de Sitobion avenae (Hemiptera: Aphididae) em quatro cultivares comerciais de trigo (Triticum aestivum L.) / Biology and behavior of Sitobion avenae (Hemiptera: Aphididae) in four commercial varieties of wheat
The use of resistant wheat cultivars to S. avenae is important for the management of culture due to the potential damage of aphid. In Brazil, however, little is known about the resistance of wheat cultivars to S. avenae. The goal of this work was to assess the behaviour and biology of S. avenae in leaves and ears of four commercial wheat cultivars to verify

14. Antibiosis and antixenosis of six commonly produced potato cultivars to the green peach aphid, Myzus persicae Sulzer (Hemiptera: Aphididae)
The antibiotic and antixenotic resistance of six commonly produced potato cultivars in Iran including Aozonia, Agria, Cosima, Cosmos, Kondor and Savalan to the green peach aphid, Myzus persicae Sulzer, were investigated under laboratory conditions at 20 ± 2ºC, 65 ± 5% RH and 16:8h (L:D) in 2009. Antibiosis experiments showed significant differences in the

15. Técnica de Criação e Aspectos Biológicos de Atheloca subrufella (Hulst) (Lepidoptera: Phycitidae) em Frutos de Coqueiro
Rearing Technique and Biological Traits of Atheloca subrufella (Hulst) (Lepidoptera: Phycitidae) in Coconut Fruits. Larvae of the coconut moth Atheloca subrufella (Hulst) develop in flowers and fruits of coconut, Cocos nucifera, causing precocious abscission of these structures and, hence, yield decrease. This work studied a feasible and suitable rearing tec

16. Morphogenetic characteristics and management of Tanzania grass.
The objective of this work was to evaluate the effect of grazing interval and period of evaluation over tissue turnover in Tanzania grass pastures (Panicum maximum cv. Tanzania) and to ascertain if herbage accumulation rate can be used as a criterion to establish a defoliation schedule for this grass in Southeast of Brazil. A randomized block design with a s

17. Biologia de Polyphagotarsonemus latus (Banks, 1904) (Acari:Tarsonemidae) em algodoeiro.
No estudo da biologia de Polyphagotarsonemus latus em algodoeiro (Gossypium hirsutun L.), cultivar IAC-20, foram utilizados discos de folhas obtidos da primeira ou da segunda folha nao-cotiledonar de plantulas cultivadas em vasos e colocados sobre uma camada de algodao umedecido com agua destilada. Os ensaios foram conduzidos a 28,5 +- 0,3C. umidade relativa

18. Cultivation of native seaweed Gracilaria domingensis (Rhodophyta) in Southern Brazil
The aim of this work was to study the cultivation of Gracilaria domingensis in a mussel farming urbanized area in Santa Catarina, Brazil. Relative growth rate was the parameter used to evaluate the cuttings attachment methods on the cultivation rope, cuttings density, cultivation period and cystocarpic versus unfertile thalli performance. The cultivation was

19. BIOLOGIA E TÉCNICAS DE CRIAÇÃO DE Trichospilus diatraeae (HYMENOPTERA: EULOPHIDAE) EM PUPAS DE Tenebrio molitor (COLEOPTERA: TENEBRIONIDAE) E Diatraea saccharalis (LEPIDOPTERA: CRAMBIDAE)
The potential for Trichospilus diatraeae Cherian &Margabandhu, 1942 (Hymenoptera:Eulophidae) as biological control agent in Brazil is unknown and, therefore, this research assessed the feasibility of pupae of Tenebrio molitor Linnaeus, 1758 (Coleoptera:Tenebrionidae) as host alternative, to optimize its production in the laboratory for the control of Diatrae

20. Asian Rust control and performance of two soybean cultivars submitted to different fungicides and application time / Controle de ferrugem asiática e desempenho de duas cultivares de soja submetidas a diferentes fungicidas e épocas de aplicações
Phakopsora pachyrhizi Syd. &Syd. is the worst threat for soybean crop in the main producers regions around the world, where significant loses has been observed. Many variables in the quantification of damage of this disease have to be studied, such as area under the disease progress curve (AUDPC), healthy leaf area absorption (HAA), healthy leaf area duratio

21. Bioecological studies on Tamarixia radiata (Waterston, 1922) (Hymenoptera: Eulophidae) in the control of Diaphorina citri Kuwayama, 1907 (Hemiptera: Psyllidae) / Estudos bioecológicos de Tamarixia radiata (Waterston, 1922) (Hymenoptera: Eulophidae) para o controle de Diaphorina citri Kuwayama, 1907 (Hemiptera: Psyllidae)
Since 2004, have been detected in citrus-growing areas of São Paulo, the bacterias that are responsible for the main disease of citrus worldwide, known as greening or huanglongbing. The widespread distribution in Brazil of the vector psyllid, Diaphorina citri and the presence of the pathogen in citrus-growing areas is a limiting factor for production. Tamar

22. Iron ore industry emissions as ecological risk factors for plant species of Anchieta restinga, Espírito Santo, Brazil / Emissões da indústria de minério de ferro como fatores de risco ecológico em espécies ocorrentes na restinga de Anchieta, Espírito Santo, Brasil
The restinga vegetation of the Espírito Santo state coast is exposed to the pollutants emitted by iron ore industry, the iron ore solid particulate matter and the wet acid deposition. To investigate the possible effects of these pollutants on the vegetation, biochemical, physiological, and ecological processes were evaluated. For that matter five native spe

23. Effect of two solanaceous plants on developmental and population parameters of the tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae)
Tuta absoluta (Meyrick) is an important tomato pest that also feeds on other host-plants from the Solanceae family. We studied the effect of two cultivated plants, tomato (Lycopersicum esculentum Mill.) and potato Solanum tuberosum L. on the development and populational parameters of T. absoluta related with host-plant suitability. Larval developmental time,

24. Estadísticos poblacionales de Triatoma rubrovaria en condiciones de laboratorio
OBJECTIVE: To obtain T. rubrovaria population parameters in order to describe its demographic characteristics. METHODS: The study was carried out in the laboratory of Arthropods, Corrientes, Argentina, from October 2000 to February 2003. Eggs were grouped to form five 100-egg cohorts. Insects were fed on chickens (Gallus domesticus). The cohorts were monitor
