1. Respostas de Sitotroga cerealella para semioquímicos e características físicas dos grãos de milho / Responses of Sitotroga cerealella to semiochemicals and physical characteristics of corn kernels
Características físicas e químicas da planta têm relação interespecífica com insetos, as quais podem ser utilizadas no Manejo Integrado de Pragas. Objetivou-se neste trabalho: i) Avaliar a resistência de cinco genótipos de milho (Zea mays) (UFVM100, UFVM200, UFVM100X200, AG1051 e DKB747) sobre S. cerealella; ii) Correlacionar as características fí

2. Expressão gênica e voláteis induzidos pela herbivoria de Spodoptera frugiperda (J. E. Smith) (Lepidoptera:Noctuidae) em milho, Zea mays L. (Poaceae) / Gene expression and volatile compounds induced by herbivory of Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) in corn, Zea mays L. (Poaceae)
Em resposta aos danos ocasionados por insetos, as plantas emitem voláteis que atraem os inimigos naturais desses herbívoros. Embora essa relação tritrófica venha sendo intensamente estudada, muitos mecanismos envolvidos nesta interação ainda permanecem inexplorados. Dentre os compostos voláteis induzidos por herbivoria e emitidos pelas plantas, os te

3. Obtaining an aromatic extract of shrimp from their industrial waste / Obtenção de um extrato aromatico de camarão a partir de seus residuos industriais
This research deals with the utilization of shrimp wastes to prepare an extract of shrimp flavor for the food industry. Three types of wastes were examined: type I, consisted of sea bobs which were either smaller than those of commercial size or damaged; type 11, was made up of resiàues from the manually peeled pink shrimp and type 111 was constituted mainl

4. Systemic release of chemical signals by herbivore-injured corn.
Corn seedlings respond to insect herbivore-inflicted injury by releasing relatively large amounts of several characteristic terpenoids and, as a result, become highly attractive to parasitic wasps that attack the herbivores. Chemical evidence showed that the induced emission of volatiles is not limited to the sites of damage but occurs throughout the plant.

5. The Effects of Abiotic Factors on Induced Volatile Emissions in Corn Plants1
Many plants respond to herbivory by releasing a specific blend of volatiles that is attractive to natural enemies of the herbivores. In corn (Zea mays), this induced odor blend is mainly composed of terpenoids and indole. The induced signal varies with plant species and genotype, but little is known about the variation due to abiotic factors. Here, we tested

6. Concerted biosynthesis of an insect elicitor of plant volatiles
A variety of agricultural plant species, including corn, respond to insect herbivore damage by releasing large quantities of volatile compounds and, as a result, become highly attractive to parasitic wasps that attack the herbivores. An elicitor of plant volatiles, N-(17-hydroxylinolenoyl)-l-glutamine, named volicitin and isolated from beet armyworm caterpil

7. Airborne signals prime plants against insect herbivore attack
Green leafy volatiles (GLV), six-carbon aldehydes, alcohols, and esters commonly emitted by plants in response to mechanical damage or herbivory, induced intact undamaged corn seedlings to rapidly produce jasmonic acid (JA) and emit sesquiterpenes. More importantly, corn seedlings previously exposed to GLV from neighboring plants produced significantly more

8. How caterpillar-damaged plants protect themselves by attracting parasitic wasps.
Parasitic and predatory arthropods often prevent plants from being severely damaged by killing herbivores as they feed on the plants. Recent studies show that a variety of plants, when injured by herbivores, emit chemical signals that guide natural enemies to the herbivores. It is unlikely that herbivore-damaged plants initiate the production of chemicals so

9. Evolution of diabroticite rootworm beetle (Chrysomelidae) receptors for Cucurbita blossom volatiles.
The diabroticite rootworm beetles coevolved with plants of the family Cucurbitaceae as demonstrated by their feeding dependence on the tetracyclic triterpenoid cucurbitacins. These beetles also exhibit strong attraction to phenylpropanoid volatile components of Cucurbita blossoms. A mixture of 1,2,4-trimethoxybenzene, indole, and (E)-cinnamaldehyde, all blos
