1. EFFECT OF THE DOWNWASH FLOW FIELD OF A SINGLE-ROTOR UAV ON DROPLET VELOCITY IN SUGARCANE PLANT PROTECTION
ABSTRACT Protecting against the main sugarcane diseases and insect pests requires good control at the base of the plant; therefore, higher droplet penetration is required during plant protection. The objectives of this research were to explore the movement mechanism of droplets in a sugarcane protection operation using a single-rotor unmanned aerial vehicle

2. Infection by the microsporidium of Clado Nosema/Vairimorpha in pupal parasitoids
Abstract: The sugarcane borer, Diatraea saccharalis is one of the hosts more used for parasitoid pupal multiplication in Brazil. The parasitoids pupal of Trichospilus diatraeae and Palmistichus elaeisis are generalist natural enemies with potential to suppress populations of diverse families of lepidopteran pests. The success in the utilization of these natu

3. Jaburetox: update on a urease-derived peptide
Abstract Urease from Canavalia ensiformis seeds was the first enzyme ever to be crystallized, in 1926. These proteins, found in plants, bacteria and fungi, present different biological properties including catalytic hydrolysis of urea, and also enzyme-independent activities, such as induction of exocytosis, pro-inflammatory effects, neurotoxicity, antifungal

4. Resistance mechanisms of sugarcane cultivars to spittlebug Mahanarva fimbriolata
ABSTRACT The spittlebug Mahanarva fimbriolata (Stål) (Hemiptera: Cercopidae) is one of the most important pests of sugarcane in Brazil. Measures for population control are currently restricted to the use of chemical insecticides and fungus Metarhizium anisopliae, in part because very little information exists regarding resistance of sugarcane cultivars. The

5. Sugarcane straw and the populations of pests and nematodes
The green cane harvesting represented a significant change in sugarcane ecosystem due to the presence of straw left on the soil and to the absence of fire. These two factors may affect the populations of pests and their natural enemies. Among the pests benefit from the green cane harvesting stand out the spittlebug, Mahanarva fimbriolata, the curculionid Sph

6. Identificação de microrganismos do trato digestivo de pragas de cana-de-açúcar com atividade enzimática para degradação de substratos lignocelulósicos e potencial para bioconversão de D-xilose em xilitol / Identification of gut microorganisms in sugarcane pests, with enzymatic activity, for degradation of lignocelullosic substrates and bioconversion of D-xylose to xylitol potential
A necessidade de economias sustentáveis tem aumentado o interesse no desenvolvimento de plataformas microbianas para novos processos, tanto para a produção de biocombustíveis quanto para a síntese de compostos que demandam alta capacidade energética e processamento químico em sua produção. O isolamento de microrganismos, capazes de degradação mate

7. Métodos para preservação de urediniósporos de Puccinia Kuehnii
Among the diseases of the culture of sugarcane in Brazil stands out the rusts. Currently, the most worrying is the orange rust due their potential for harm. The objectives were to test the feasibility periods of uredinósporos, preservation methods and influence of aqueous extracts in the in vitro germination urediniospores of Puccinia kuehnii.The work was d

8. Aspectos bioecológicos de dermápteros (Insecta, Dermaptera) presentes em canaviais da região de Piracicaba / Bioecological aspects of Dermaptera naturally occurring in sugar cane fields located in Piracicaba, state of São Paulo, Brazil
A partir de 2017 ficará proibida a queima nos canaviais, tornando obrigatória a colheita sem queima prévia. Esta nova tendência de colheita irá resultar em mudanças nas relações tróficas presentes no canavial. A broca da cana (Diatraea saccharalis) é considerada uma pragachave da cultura e é responsável por uma perda significante de produtividade

9. Induction of insect plant resistance to the spittlebug Mahanarva fimbriolata Stål (Hemiptera: Cercopidae) in sugarcane by silicon application
Changes in the agroecosystem with the increase of green cane harvesting in Brazil affected the insect populations associated to this crop, and secondary pests like the spittlebug Mahanarva fimbriolata Stål, became much more important. Many studies have demonstrated the active role played by silicon in plant defense against herbivory. The objective of this s

10. Laboratory and field evaluation of Metarhizium anisopliae var. anisopliae for controlling subterranean termites
The efficacy of the Metarhizium anisopliae strain ARSEF 6911 was determined in the laboratory and field against two sugarcane pests, Microtermes obesi Holmgren and Odontotermes obesus Rambur (Termitidae: Isoptera). The susceptibility of both termite species to different conidial suspensions (1 × 10(10), 1 × 10(8), 1 × 10(6) and 1 × 10(4) conidia/ml) was

11. Interaction of Metarhizium anisopliae (Metsch), Beauveria bassiana (Bals.) and granulovirus, the main pathogens of Diatraea saccharalis (Fabr., 1794) (Lepidoptera: Crambidae) / Interação de Metarhizium anisopliae (Metsch.), Beauveria bassiana (Bals.) e vírus da granulose, principais patógenos de Diatraea saccharalis (Fabr., 1794) (Lepidoptera: Crambidae)
The sugarcane borer, Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) is naturally infected by various pathogens, the most important are Metarhizium anisopliae (Metsch) (Ascomycota: Clavicipitaceae), Beauveria bassiana (Bals.) (Ascomycota: Cordycipitaceae) and granulovirus. These microorganisms may coinfect the same host under field conditions

12. Comparação da diversidade microbiana intestinal em larvas do campo e laboratório do bicudo da cana-de-açúcar, Sphenophorus levis (Coleoptera, Cucurlionidae)
The sugarcane weevil, Sphenophorus levis, is an important pest in sugarcane culture in São Paulo state, Brazil. To complete its life cycle, S. levis may depends on microorganisms that inhabit its intestinal tract and play an important key in the insect physiology and nutrition. In this study we report the characterization of the intestinal microbiota from p
