27. Análise comparativa da predação de Toxoptera citricidus (Kirkaldy) e Aphis spiraecola (Patch) (Hemiptera: Aphididae) por artrópodes, em cultura de citros, através da serologia
Citriculture is one of the most important agricultural activities in Brazil, and its production, specially directed to the export of concentrated juice, generates profits that surpass one billion dollars a year. In the present work, specific antisera for Aphis spiraecola (Patch) and Toxoptera citricidus (Kirkaldy) (Hemiptera: Aphididae) were produced, and po

28. Inheritance of resistance to cotton blue disease.
The objective of this work was to determine the inheritance of cotton blue disease resistance by cotton plants. Populations derived from the CD 401 and Delta Opal resistant varieties were evaluated, through a greenhouse test with artificial inoculation by viruliferous aphids. Cotton blue disease resistance is conditioned by one dominant gene, both in CD 401

29. Longevity, fecundity and embryogenesis in brazilian aphids.
Afideos causam grande dano a cereais cultivados. Com o objetivo de subsidiar programas de controle, propriedades biologicas sujeitas a forte pressao de selecao foram estudadas nas especies sul-brasileiras Schizaphis graminum, Sitobion avenae e Rhopalosiphum padi (Homoptera:Aphididae). Mudancas na morfologia externa dos embrioes foram analisadas sob microscop

30. Controle biolÃgico e alternativo da cochonilha (Phenacoccus manihoti Matile-Ferrero) na cultura da mandioca (Manihot esculenta Crantz) / Biological control and alternative mealybug (Phenacoccus manihoti Matile-Ferrero) in cassava crop (Manihot esculenta Crantz)
This study aimed to evaluate the action of entomopathogenic fungi and plant protection products used in alternative agroecological on nymphs of P. manihoti in cassava. The four upper leaves of cassava plants infested with nymphs of the mealybug P. manihoti application of treatments received in the lower surface of leaves on the nymphs, using a spray nozzle a

31. Resistência de cultivares de batata a Myzus persicae (Sulz.)(Hemiptera: Aphididae)
Aphids are the most important vectors of viruses infecting potato (Solanum tuberosum). We focused on the response of the aphid vector Myzus persicae (Sulzer) to five commercial potatocultivars: Ágata, Jaette Bintje, Mondial, Monalisa and Santè, by traditional antibiosis and antixenosis tests and by the EPG (Electrical Penetration Graph) technique, as a ste

32. Effects of genetically modified cotton (Bollgard®) on non-target organisms / Efeitos do algodoeiro geneticamente modificado (Bollgard®) em organismos não-alvo
The effects of the genetically modified cotton (Bollgard®) expressing Bacillus thuringiensis (Bt) Cry1Ac toxin on non-target arthropods was evaluated under laboratory and field studies. Evaluations of arthropod abundance on Bollgard® cotton (Delta Pine 90) and on its isoline (Acala 90) were carried out during three consecutive field seasons. The first stud

35. Biological control of Aphis gossypii Glover (Hemiptera: Aphididae) in protected crop of cucumber using Marigold (Tagetes erecta L.) / Controle BiolÃgico do pulgÃo Aphis gossypii Glover (Hemiptera: Aphidae) em cultivo protegido de pepino com cravo-de-defunto (Tageres erecta L.)
Protected crop is a used practice in Brazil and abroad. Some characteristics like stable climate, high temperature and availability of food, favor the occurrence of pests on these systems, among them the Aphis gossypii. These insects are usually controlled chemically, which when applied in closed systems have little dispersion, thereby increasing its concent
