Brazilian forest producers have developed integrated management programs to increase the effectiveness of control leaf-cutting ants genera Atta and Acromyrmex. These measures reduced costs quantity insecticides used in plantations. Such are based on monitoring ant nests, as well need timing methods. Chemical employing baits is most commonly method, however, biological, mechanical cultural methods, besides plant resistance, can reduce chemicals applied
Abstract Agrosilvopastoral and silvopastoral systems can increase carbon sequestration, offset greenhouse gas (GHG) emissions reduce the footprint generated by animal production. The objective of this study was to estimate GHG emissions, tree grass aboveground biomass production storage in different agrosilvopastoral southeastern Brazil. number trees required these were also estimated. calculated based on pre-farm (e.g. agrochemical production, storage, transportation), on-farm activities...
Copaifera langsdorffii Desf. (Kuntze) (Fabaceae) is a slow-growing tree, reaching 25 to 40 meters in height and living up 400 years, with wide distribution South America. The objective of this work was report, for the first time, occurrence Oncideres dejeanii Thomson (Coleoptera: Cerambycidae) cutting using C. as host. Adults O. were observed cutting, dropping, ovipositing on tree branches shoots langsdorffii, gallery forest, Diamantina, Minas Gerais state, Brazil. plant species beetle have...
Forest plantations represent the fourth largest crop by planted area in Brazil. However, leaf-cutting ants can compromise their establishment and development. Atta Acromyrmex (Hymenoptera: Formicidae) ant genera are main pests Eucalyptus Pinus plantations, management is fundamental to maintain forestry sector. Here, we describe biological aspects of Brazilian commercial forest feasibility different methods control these insects. Physical not effective suppressing nests any size. Chemical...
Species of Oncideres Serville, often referred to as twig girdlers, girdle tree branches prior oviposition promote larval development. The behavior creates a unique niche that is utilized by other beetle species. objective this study was compare emergence insects from girdled saga Dalman in an intercropping system and monoculture Acacia mangium Willd. the Atlantic Rainforest Minas Gerais, Brazil. Twenty-four Coleoptera species emerged branches: 17 Cerambycidae; three Cleridae; one individual...
Forestry companies study the population dynamics of insect pests in Integrated Pest Management for cost effectiveness. The objective this was to obtain qualitative and quantitative information on fluctuation Lepidopteran defoliators Eucalyptus urophylla plants Brazilian Amazon rainforest. In all, 402 species were collected, which 10 primary pests, nine secondary remaining bore no definite relevance eucalyptus. Primary formed a low percentage total species, although they recorded high number...
Twig girdlers are beetles that girdle branches and trunks of living trees so they can deposit their eggs in incisions made by mandibles. There few studies about the biology ecology girdler Oncideres ocularis Thomson, which is considered a potential pest forest plantations cause injuries to tree species family Fabaceae. The objective this study was increase knowledge related biological phases ecological patterns girdling oviposition O. ocularis. Field were conducted at four Acacia mangium...
Abstract Acacia mangium is a pioneer species with fast growth and frequently used in the recovery of degraded areas. The objectives were to evaluate insects spiders, their ecological indices interactions on A. saplings tropical area recovering process. experimental design was completely randomized 24 replications, treatments represented by first second years after seedling planted. Numbers leaves/branch, branches/sapling, ground cover saplings, Hemiptera: Phenacoccus sp. Pachycoris torridus;...
Mimosa bimucronata (DC.) Kuntze (Fabaceae) is recorded as a host of Oncideres ocularis Thomson, 1868 (Coleoptera: Cerambycidae), and this the first report twig girdler in southeast region Brazil. The history beetles pests Fabaceae trees indicates that tree species can be damaged areas where insect occurs.
Abstract Caryocar brasiliense Camb. (Malpighiales: Caryocaraceae) trees have a wide distribution in the Cerrado, and it is protected by federal laws. The need to monitor understand pest damage crops forests major motivation for study of population distribution. mites (Acari) distributions on C. are unknown. We studied seasonal mite their ecological indices Cerrado areas during three years. Greatest number Agistemus sp. (Stigmaeidae), Histiostoma (Histiostomidae), Proctolaelaps (Ascidae),...
The twig girdler beetles are known for damaging many tree species.These girdle branches and use them to lay their eggs complete the offspring development.The objective of this work was describe occurrence a case O. dejeanii girdling Pyrus pyrifolia (pear tree) branches.Three girdled P. were collected on two these captured female twig-girdler beetle each.The diameter average length 3.47±0.15cm 3.31±0.17m, respectively.The lower third branch has presented 52% posture incisions.A observed...
Abstract Caryocar brasiliense Camb. (Malpighiales: Caryocaraceae) is widely distributed in the Brazilian savanna and its fruits are used by humans for food, production of cosmetics, lubricants, pharmaceutical industry. This plant damaged galling insects. Number these insects their parasitoids was recorded, field (galls) laboratory (adults emerged from galls), three C. crown heights, during years. Numbers adults Eurytoma sp. (Hymenoptera: Eurytomidae), insect (younger attack) Sycophila...
Abstract Acacia auriculiformis A. Cunn. Ex Benth. (Fabaceae), a non-native pioneer species in Brazil with fast growth and rusticity, is used restoration programs. Our goal was to assess during 24-month survey the pattern of arthropods (phytophagous insects, bees, spiders, predator insects) on leaf surfaces saplings. Fourteen phytophagous, two bees eleven predators were most abundant adaxial surface. The values ecological indexes (abundance, diversity, richness) rarefaction, k-dominance...
Hypsipyla grandella (Lepidoptera: Pyralidae) is found throughout Central and South America, except in Chile. Damage caused by this pest native trees of the subfamily Swietenoideae (Meliaceae) so intense severe that it makes industrial forestry with those species unfeasible. It also may damage fruits seeds trees. to reproductive structures compromise natural regeneration impair seedling production. Management tactics for include use resistant exotic Meliaceae, such as Australian red cedar...
Bauhinia variegata (Fabaceae), an exotic tree used in urban forestry and landscaping Brazil, is predisposed to damage by phytophagous insects, especially under stress conditions. The mealybug Praelongorthezia praelonga (Douglas 1981) (Hemiptera: Ortheziidae) a generalist pest. Here we report potential mortality of B. trees P. the environment at Montes Claros municipality, Minas Gerais State, Brazil. This insect damages host directly through feeding, indirectly supporting growth sooty mold...
. The objective was to study the habitat complexity of mite populations on Caryocar brasiliense trees under natural and cultivated field conditions. performed in municipality Montes Claros, state Minas Gerais, Brazil, over 3 years. Three types areas were studied: 1) Cerrado, 2) pasture, 3) a university Campus. Several chlorotic spots detected leaves with larger Tetranychus sp. Eutetranychus (Tetranychidae). greatest numbers Agistemus (Stigmaeidae) Histiostoma (Histiostomidae) Proctolaelaps...
Acacia mangium (Willd., 1806) (Fabales: Fabaceae) is a fast growing, rustic, pioneer species, with potential to fix nitrogen, and for programs recover degraded areas. The objective was evaluate the distribution functional diversity of interactions K-dominance arthropod groups on A. saplings. number individuals eleven species phytophagous insects, three bee fourteen natural enemy were highest adaxial leaf surface this plant. Abundance, richness insects enemies, abundance pollinators surface....
The objective of this study was to analyze whether the morphology girdled twigs has an effect on number incisions and reproductive success Oncideres ocularis (Coleoptera: Cerambycidae). Eight parameters branches were evaluated. Surface area showed highest coefficient determination for eggs laid per branch hatched larvae. area, volume length correlated significantly with larvae, as been reported similar insects.
