1. Novel Insecticides from Alkylated and Acylated Derivatives of Thymol and Eugenol for the Control of Plutella xylostella (Lepidoptera: Plutellidae)
Plutella xylostella cause considerable harm to the production of broccoli, Chinese cabbage, cabbage and cauliflower. The control of P. xylostella is mainly performed using commercial insecticides, which have even led to the emergence of resistant populations. Two easily available natural products found in different plants essential oil, thymol and eugenol, s

2. Development of the mosaic of dominant arboreal ants and its importance to the biological control of insects associated with cocoa (Theobroma cacao L.) / Desenvolvimento do mosaico de formigas arborícolas dominantes e sua importância no controle biológico natural dos insetos associados ao cacaueiro (Theobroma cacao L.)
Agroforests contribute to the survival of many native species. The cocoa plantations inserted in the Atlantic Forest biome in Southeast Bahia contribute to the conservation of a large amount of organisms, including ants. The evaluation of the ontogenetic succession of ants can help understanding the mosaic dynamics of the arboreal ants. Since this mosaic can

3. Avaliação do impacto da variabilidade/mudanças climáticas sobre Euschistus heros, Telenomus podisi e ferrugem asiática na soja, no Região Sul do Brasil / Risk assessment of variability/climate change on the Euschistus heros, Telenomus podisi and asian soybean rust of soybean, in the southern region of Brazil
Brazil is the second largest soybean producer, however, biotic and abiotic factors affect the crop, causing serious damage, with significant economic impact. Among these problems, Euschistus heros and asian soybean rust. For biological control of the insects, the parasitoid Telenomus podisi has been described as one of the potential agents in MIP programs. T

4. NEMATÓIDES ENTOMOPATOGÊNICOS COMO CONTROLADORES BIOLÓGICOS DE CIGARRINHAS DO GÊNERO Mahanarva (HEMIPTERA: CERCOPIDAE)
The spittlebugs belonging to the genus Mahanarva cause damage to the Poaceae family cultures, like signal grass, elephant grass and sugar cane, by the sap feeding on roots (immature phase) and leaves (adult phase). With the increase demand to reduce use of chemical insecticides for the insect pests control, comes the need to develop new control methods. In t

5. Controle de Xanthomonas citri subsp. citri em citros (Citrus sinensis) mediado por neonicotinóides
O cancro cítrico é uma doença de importância mundial para o cultivo comercial de citros. O desenvolvimento de medidas alternativas de controle que contribuam para o manejo da doença é de grande importância. O presente estudo teve como objetivo verificar se o tratamento de plantas cítricas com inseticidas neonicotinóides é capaz de controlar a incid

6. Utilização sistêmica de Bacillus thuringiensis para controle de Plutella xylostella na cultura de couve
The diamondback moth (DM) Plutella xylostella (Lepidoptera: Plutellidae) is the major pest of crucifer culture and the chemical control is the method most used to reduce its damage. An alternative to control this pest is the use of biological control agents, such as Bacillus thuringiensis (Bt). Its use is still limited when compared to chemical insecticides,

7. Variação sazonal de Triozoida limbata (Hemiptera: Triozidae) e inimigos naturais em goiabeira / Seasonal variation of Triozoida limbata (Hemiptera: Triozidae) and natural enemies in guava plants
Triozoida limbata is one of the most important pests of guava plants. Their nymphs attack young leaves and buds, causing serious damages. Basic studies of population dynamics and determination of factors that regulate the population growth are necessary for the development of integrated programs management of this pest. Agents of natural biological control a

8. Caracterização e seleção de isolados de Beauveria bassiana para o controle microbiano do carrapato Boophilus microplus / Characterization and selection of Beauveria bassiana isolates to microbiological control of Boophilus microplus tick
Beauveria bassiana is an entomopathogenic fungus used worldwide as a biological control agent of pest arthropods. The present study aimed at characterizing several isolates of B. bassiana and selects those with major potential to control ticks population and other arthropods under natural conditions. Thus, 53 isolates of B. bassiana and 7 isolates including

9. Ecologia do bicudo-do-algodoeiro Anthonomus grandis Boheman, 1843 (Coleoptera:Curculionidae) no Cerrado do Brasil Central
The boll weevil Anthonomus grandis Boheman, 1843 (Coleoptera: Curculionidae), one of the main pests of cotton, was introduced in Brazil in 1983. It causes the most serious damage to the crop, such as the falling of the flower buds, destruction of bolls and reduced linter production. The serious pest status of the boll weevil is mainly due to its high reprodu

10. 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

11. Estudos Sobre os efeitos de um produto a base de Bacillus Thuringiensis var. Kurstaki em Ephestia Kuehniella (Zeller, 1879) (Lepidoptera: Pyralidade) e no seu Ectoparasitoide Bracon hebetor (Say, 1836) (Hymenoptera: Braconidae)
Ephestia kuehniella is a very important pest, attacking wheat flour in mills and stored places. Due to the negative impact of the chemical control methods, alternative agents are being studied to reach more safety and more satisfactory results. Some biological, physical and mechanical components should be adequate to be includes in integrated pest management

12. Avaliação de agentes biológicos e seus produtos na incidência de lesões foliares do cancro cítrico
O cancro cítrico, causado por Xanthomonas axonopodis pv. citri (Xac), é um grave problema para a citricultura, pois o principal método de controle é a erradicação das plantas contaminadas. O controle biológico com microrganismos representa uma alternativa no controle da doença. Foram obtidos quatro isolados bacterianos, de lesões de cancro cítrico
