Plants have been recognized as a good source of insecticidal agents, since they are able to produce their own defensives insect attack. Moreover, there is growing concern worldwide develop pesticides with low impact environment and non-target organisms. Hexane-soluble fraction from ethanolic crude extract fruits Manilkara subsericea its triterpenes were considered active against cotton pest (Dysdercus peruvianus). Several natural products activity poor water solubility, including...
Myrciaria floribunda (H. West ex Willd.) O. Berg, Myrtaceae, is a native plant species of the Atlantic Rain Forest, from north to south Brazil. The lyophilized ethyl acetate extract leaves M. was investigated for its antiproliferative activity in tumor cell lines, antioxidant capacity and total phenolic, flavonoid tannin contents. Antiproliferative tested vitro against seven human cancer cells immortalized skin keratinocytes line (HaCat, no cell). Antioxidant determined using...
Myrciaria floribunda (H. West ex Willd.) O. Berg, Myrtaceae, is popularly known as "camboim-amarelo" and was collected at Restinga de Jurubatiba (RJ, Brazil). Leaves from this species were submitted to hydrodistillation extract its essential oil. Monoterpenes the main compounds found (53.9%), 1,8-cineole major constituent (38.4%). Studies carried out evaluate effects of oil on development two agricultural pests (Oncopeltus fasciatus Dysdercus peruvianus). The considered effective against D....
Zanthoxylum caribaeum Lamarck (Rutaceae) is plant species with a variety of medical applications, including insecticidal activity. This study determined the bioacaricidal activity essential oil from Z. leaves against engorged Rhipicephalus (Boophilus) microplus (Canestrini, 1887) females using adult immersion test. For this purpose, three serial concentrations (5.0, 2.5, and 1.25%, vol:vol, in 1% dimetilsulfoxide) were used. Essential 5% caused 65% mortality on first day after treatment, 85%...
BACKGROUND This work describes a chemical study of the essential oil from leaves Xylopia ochrantha, an endemic Annonaceae species Brazil, and its activity against Biomphalaria species. Considering poor solubility in aqueous medium, was nanoemulsified to evaluate action on controlling some mollusc genus Biomphalaria, snail hosts Schistosoma mansoni that causes schistosomiasis, which mainly affects tropical subtropical countries. OBJECTIVES The main aims this were analyse composition X. effect...
The main strategy of interrupting Trypanossoma cruzi transmission is to control the vector populations. Studies new agents with activity against these vectors have a priority interest. This study evaluated insecticidal essential oil Myrciaria floribunda nymphs R. prolixus. M. was collected in Jurubatiba Sandbank (southeastern Brazil). Leaves were extracted by hydrodistillation and analyzed mass spectrometry flame ionization gas chromatography. pure at various dilutions or purified...
Essential oils are known for their insect control potential, which is mainly attributed to the presence of terpenes that interfere with hormonal and physiological processes arthropods. The aim present study was evaluate effects essential oil from leaves Eugenia sulcata Spring ex Mart., Myrtaceae, on development two species agricultural pest insects, Dysdercus peruvianus Oncopeltus fasciatus. Results showed induced mortality, reduced numbers adults. Topical treatment fasciatus using pure...
Neomitranthes obscura (DC.) N. Silveira is an endemic plant of Brazilian Atlantic Forest and widely spread in the sandbanks "Restinga de Jurubatiba" National Park. It popularly known by local population as "camboim-de-cachorro" or "cambuí-preto" recognized its black ripe fruits. However, specimens with yellow fruits were localized The aim present study was to evaluate chemical composition essential oils obtained from leaves different fruit color (black yellow) GC GC-MS. Essential indicated a...
Although several species of ferns possess a characteristic odor, only few published studies have described their volatile constituents. The aim the present study was to evaluate chemical composition essential oils from two chemically unexplored fern species, Anemia hirsuta and raddiana. These were collected during day in ravine banks Rio de Janeiro state, Brazil. Fresh leaves individually turbolized with distilled water submitted hydrodistillation Clevenger-type apparatus for three hours....
Agricultural crops need protection from a variety of different insects popularly known as pests. Some these pests are becoming increasingly resistant to conventional pesticides, so new control alternatives needed. In this work, the effects essential oil plant Zanthoxylum caribaeum on development cotton stink bug Dysdercus peruvianus were analyzed. After analysis by chromatography and mass spectrometry, Z. presented 54 substances, main constituents being Sylvestrene, Muurola-4 (14),...
Abstract Galls, neo-formed plant structures that can occur in different organs, are generated by species-specific interaction with an inducing organism. Inducers manipulate the metabolism of its host. Microgramma vacciniifolia (Langsd. & Fisch.) Copel. is a Neotropical epiphytic fern hosted two stem galls, one induced midge species (Diptera) and other micromoth (Lepidoptera). The aim this study was to evaluate impact these gall-inducing insects on biochemistry phenolic acids cyanogenesis...
