13. Flutuacao populacional do predador Doru luteipes Scudder em plantas de milho.
O predador Doru luteipes Scudder (Dermaptera: Forficulidae) tem-se mostrado um inseto com grande potencial no controle biologico de 2 das principais pragas do milho. Spodoptera frugiperda (Smith) e Helicoverpa zea (Boddie). Este trabalho teve como objetivo estudar a flutuacao do predador em milho, durante seis anos, em plantios mensais, em Sete Lagoas, MG, B

15. Desenvolvimento e qualidade de Trichospilus diatraeae (Hymenoptera: Eulophidae) utilizando hospedeiros alternativos / Development and quality of Trichospilus diatraeae (Hymenoptera: Eulophidae) using alternative hosts
Parasitoids are important because of their diversity and they regulate populations of insects of different orders, however to use them in the field depends on studies to improve their mass rearing. The objective of this work was to study reproductive factors of Trichospilus diatraeae Cherian &Margabandhu (Hymenoptera: Eulophidae) on pupae of Anticarsia gemma

16. Interações entre o predador Podisus nigrispinus (Heteroptera: Pentatomidae) e o parasitóide Palmistichus elaeisis (Hymenoptera: Eulophidae) / Interactions among the predator Podisus nigrispinus (Heteroptera: Pentatomidae) and the parasitoid Palmistichus elaeisis (Hymenoptera: Eulophidae)
The use of more than one natural enemy for pests control can increase the efficiency of the biological control, mainly, when those organisms act on different apprenticeships of the pests. The diversification of the beneficial fauna can reduce the population of herbivores and the disturbance of the ecosystems, increasing the local stability. The objective was

17. Mirmecofilia em Parrahasius polibetes (Lepidoptera: Lycaenidae) : historia natural, custos, seleção de planta hospedeira e beneficios da co-correncia com hemipteros mirmecofilos / Mymecophily ion Parrhansius polibetes (Lepidoptera: Lycaenidae) : natural history costs, host-plant selection, and benefits of co-ocurrece with myrmecophilous hemipterans
Ants are one of the most prominent groups of terrestrial organisms in terms of diversity, relative abundance and biomass. Their importance is due primarily to eusocial behavior combined with complex communication systems. Tropical foliage is rich in renewable feeding sources that promote ant foraging. As some of the most important predators on plants, ants s

18. Editorial
The tomato moth, Tuta absoluta Meyrick, is one of the most important tomato pests in South America. In Argentina, management strategies include only chemical control. In this work, the parasitoid wasp Trichogrammatoidea bactrae Nagaraja was evaluated as a potential natural enemy against this pest. Biological and population parameters were estimated by develo

19. Primeira ocorrência de Alcaeorrhynchus grandis (Dallas) (Hemiptera: Pentatomidae) predando lagartas desfolhadoras do dendezeiro no estado do Pará
The oil palm Elaeis guineensis is usually attacked by pests, particularly, defoliating caterpillars. Between 2004 and 2006 a stinkbug predator (Asopinae) was registered preying on caterpillars of Brassolis sophorae L., Opsiphanes invirae Hübner (Lepidoptera: Nymphalidae) and Sibine spp. (Lepidoptera: Limacodidae), reducing their populations in commercial oi

20. O efeito inimigo íntimo é aplicável a Dinoponera quadríceps (Hymenoptera, Formicidae)?
Food access, territory or reproductive partner can generate conflicts between individuals in many species with occurrence of aggressive behaviors. However some species respond less aggressively to intrusion by neighbors than non-neighbors in its territory to minimize the costs of continuous fight. This difference in aggression is called Dear Enemy Effect des

21. Bioecological studies of Neozygites floridana (Entomophthorales: Neozygiteceae), the fungal pathogen of Tetranychus evansi (Acari: Tetranychidae) / Estudos bioecológicos de Neozygites floridana (Entomophthorales: Neozygitaceae) fungo patogênico de Tetranychus evansi (Acari: Tetranychidae)
The tomato red spider mite, Tetranychus evansi Baker and Pritchard is an important exotic pest of Solanaceae in Europe and Africa. It is suggested that this mite could have originated from South America, a region where it is not considered as an important pest. An important natural enemy of T. evansi in Brazil is the fungus Neozygites floridana Weiser and Mu

22. Ocorrência e bionomia de Ctenarytaina eucalypti (Maskell) (Hemiptera: Psyllidae) e seu inimigo natural Psyllaephagus pilosus Noyes (Hymenoptera: Encyrtidae) em plantas de Eucalyptus globulus / Occurrence and bionomy of Ctenarytaina eucalypti (Maskell) (Hemiptera: Psyllidae) and its natural enemy Psyllaephagus pilosus Noyes (Hymenoptera: Encyrtidae) in plants of Eucalyptus globulus.
Species of the genus Eucalyptus hosting several species of insects of the family Psyllidae. Among them, the specie Ctenarytaina eucalypti (Maskell) (Hemiptera: Psyllidae) is considered the most harmful, causing damage to culture wherever it has been introduced. To control these hemiptera phytophage, treatment with insecticides proved to be costly and unsusta

23. Rearing technique and parasitism aspects of Opius sp. (Hymenoptera: Braconidae) on the leafminer Liriomyza trifolii (Diptera: Agromyzidae) on melon plants / Técnica de criação e aspectos do parasitismo de Opius sp. (Hymenoptera: Braconidae) sobre a mosca-minadora, Liriomyza trifolii (Diptera: Agromyzidae), em meloeiro
The leafminer Liriomyza trifolii is nowadays the main pest of melon orchards in the region of Chapada do Apodi, Northeast of Brazil. In order of the high infestation level of this insect, the control based only in pesticides has not been plenty satisfactory. However, considerable parasitism levels occasioned by Opius sp. have been found in field, mainly in t
