25. Differential expression of the pr1A gene in Metarhizium anisopliae and Metarhizium acridum across different culture conditions and during pathogenesis
The entomopathogenic fungi of the genus Metarhizium have several subtilisin-like proteases that are involved in pathogenesis and these have been used to investigate genes that are differentially expressed in response to different growth conditions. The identification and characterization of these proteases can provide insight into how the fungus is capable o

26. Sequential sampling of Euschistus heros (Heteroptera: Pentatomidae) in soybean
Integrated pest management programs for soybean (Glycine max (L.) Merrill) must be based on efficient sampling plans for estimating the pest population. Based on the spatial distribution of the Neotropical brown stink bug Euschistus heros (Fabricius, 1794) found on soybean, it was possible to construct a sequential sampling plan for the survey of this insect

27. Biological Control in Brazil: an overview
The use of Biological Control methods is on the increase, mainly as a result of the mobilization of human resources in entomology studies since the establishment of graduate programs in this country in the 1960s. This review approaches the retrospective of Biological Control in Brazil in recent decades, with an emphasis on the "culture of applying agrochemic

28. Effects of essential oil from leaves of Eugenia sulcata on the development of agricultural pest insects
Essential oils are known for their insect control potential, which is mainly attributed to the presence of terpenes that interfere with hormonal and physiological processes of arthropods. The aim of the present study was to evaluate the effects of essential oil from the leaves of Eugenia sulcata Spring ex Mart., Myrtaceae, on the development of two species o

29. Large scale artificial rearing of Anastrepha sp.1 aff. fraterculus (Diptera: Tephritidae) in Brazil
Some species of the genus Anastrepha (Diptera: Tephritidae) are successfully managed by matching the sterile insect technique with parasitoid releases. Such strategies used in integrated pest management can be implemented only where insect mass-rearing programs are feasible. In this study, we show the process of domestication, rearing technology and quality

30. Laboratory evaluation of the effects of essential oil of Myrciaria floribunda leaves on the development of Dysdercus peruvianus and Oncopeltus fasciatus
Myrciaria floribunda (H. West ex Willd.) O. Berg, Myrtaceae, is popularly known as "camboim-amarelo" and was collected at Restinga de Jurubatiba (RJ, Brazil). Leaves from this species were submitted to hydrodistillation to extract its essential oil. Monoterpenes were the main compounds found (53.9%), and 1,8-cineole was the major constituent (38.4%).

31. Advances and Perspectives of the use of the entomopathogenic fungi beauveria bassiana and metarhizium anisopliae for the control of arthropod pests in poultry production
Global poultry production is plagued by a wide variety of arthropods. The problems associated with their chemical control have led to an increasing search for control alternatives, and entomopathogenic fungi seem to be a promising strategy. Despite the large number of insects and mites considered as important pests in animal production, studies on the use of

32. Insects associated with tropical foliage produced in the coffee growing region of Colombia
We conducted a survey of insects and pest management practices on 34 farms growing ornamental tropical foliage plants in the central coffee region of Colombia over two years. Tropical foliage provided habitat for a diverse range of insects. In total, phytophagous or detritivorous insects from six orders, 40 families and 62 genera were collected. The most com

33. Diversidade de himenópteros parasitoides (Hymenoptera: Chalcididae) e coleobrocas (Coleoptera: Cerambycidae) associados à cultura de Tectona grandis Linn. f. (Lamiaceae) / Diversity of parasitoids (Hymenoptera: Chalcididae) and wood borers (Coleoptera: Cerambycidae) in teak Tectona grandis linn. f. (Lamiaceae)
Com o objetivo de analisar a fauna de himenópteros parasitoides (Hymenoptera:Chalcididae) e de coleobrocas (Coleoptera: Cerambycidae) associados à cultura de T. grandis, foram utilizadas 5 armadilhas de Malaise instaladas no interior da floresta plantada. As coletas foram realizadas, semanalmente, de outubro de 2009 a setembro de 2010, em área de reflores

34. Diversidade genética de Diaphorina citri Kuwayama, 1908 (Hemiptera: Psyllidae) e caracterização molecular das linhagens de Wolbachia associadas / Genetic diversity of Diaphorina citri Kuwayama, 1908 (Hemiptera: Psyllidae) and molecular characterization of the associate strains of Wolbachia
Diaphorina citri Kuwayama, 1908 (Hemiptera: Psyllidae) is an exotic insect in Brazil, first recorded in the 40s. Although it causes direct damage, D. citri only received attention as a pest in 2004, when the \"Huanglonbing\" (HLB) disease was confirmed infecting citrus in Brazil, and subsequently related to D. citri as vector. Currently, there is no cure for

35. Variability in the production of extracellular enzymes by entomopathogenic fungi grown on different substrates
Entomopathogenic fungi are important controllers of pest-insects populations in agricultural production systems and in natural environment. These fungi have enzymatic machinery which involve since the recognition and adherence of spores in their hosts culminating with infection and death of these insects. The main objective of this study was to analyzed extr
