FORMULAÇÃO MULTICOMPONENTE PARA MONITORAMENTO DE LEPIDÓPTEROS PRAGA EM ÁREAS DE SOJA NO MATO GROSSO

Fabiane Rezende BetoniEliza Vitória M. Viana

Abstract

Introdução: O complexo de lepidópteros-praga da soja, tem afetado diretamente a produção devido aos prejuízos pela destruição direta das vagens, além de reduzir a área fotossintética das plantas, pela desfolha. Com isso, faz-se necessário aplicações sucessivas de inseticidas, que impactam drasticamente o meio ambiente. Desta forma, uma alternativa sustentável para minimizar tais impactos, seria a utilização de feromônio sexual, que são sinais químicos emitidos pelos lepidópteros para o acasalamento. Estes feromônios podem conter compostos comuns atrativos a diferentes mariposas que conseguem ser usados para mais de uma espécie, ajudando assim o monitoramento nas lavouras de soja. Objetivo: Avaliar a eficiência de duas formulações multicomponentes no monitoramento de lepidópteros-praga da cultura da soja. Material e métodos: O experimento foi conduzido em delineamento inteiramente casualizado em uma área de soja no município de Tangará da Serra – MT, onde foram utilizadas armadilhas do tipo delta, de cor branca, para a captura dos adultos. As armadilhas ficaram dispostas a 100m da bordadura, distanciadas uma da outra a 50m. Foram avaliadas duas formulações multicomponentes e como controle utilizou-se hexano. Foram efetuadas cinc...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Hereditary Sensory Autonomic Neuropathy

Hereditary Sensory Autonomic Neuropathies are a group of inherited neurodegenerative disorders characterized clinically by loss of sensation and autonomic dysfunction. Here is the latest research on these neuropathies.

Spatio-Temporal Regulation of DNA Repair

DNA repair is a complex process regulated by several different classes of enzymes, including ligases, endonucleases, and polymerases. This feed focuses on the spatial and temporal regulation that accompanies DNA damage signaling and repair enzymes and processes.

Glut1 Deficiency

Glut1 deficiency, an autosomal dominant, genetic metabolic disorder associated with a deficiency of GLUT1, the protein that transports glucose across the blood brain barrier, is characterized by mental and motor developmental delays and infantile seizures. Follow the latest research on Glut1 deficiency with this feed.

Separation Anxiety

Separation anxiety is a type of anxiety disorder that involves excessive distress and anxiety with separation. This may include separation from places or people to which they have a strong emotional connection with. It often affects children more than adults. Here is the latest research on separation anxiety.

KIF1A Associated Neurological Disorder

KIF1A associated neurological disorder (KAND) is a rare neurodegenerative condition caused by mutations in the KIF1A gene. KAND may present with a wide range and severity of symptoms including stiff or weak leg muscles, low muscle tone, a lack of muscle coordination and balance, and intellectual disability. Find the latest research on KAND here.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds.
