In the present work, hematite (α-Fe2O3) nanoparticles (NPs) were synthesized by using a simple and facile green synthesis Hibiscus plant extract. The used solution is composed of extract 0.1 M iron chloride mixture. are grown at ambient temperature. prepared morphology, structure composition characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive spectroscop...

A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of Roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Two inter-row spacing (60 and 90 cm) and three intra-row spacing (30, 60 and 90 cm) were evaluated using two varieties, WG-Hi...

Foreign exploration for natural enemies of pink hibiscus mealybug, Maconellicoccus hirsutus , was conducted in Australia from 2000 to 2002. In Queensland, the predaceous beetle Cryptolaemus montrouzieri , the predaceous drosophilid fly, Cacoxenus perspicax and the encrytid parasitoid Gyranusoidea indica were recovered. In Western Australia and the Northern Territory a predatory noctuid , Mataeo...

Waru leaf (Hibiscus tiliaceus) is plant that contains natural flavonoids and phenolic compounds useful as an antioxidant. Flavonoids phenolics can be extracted optimally if using a suitable extraction solvents. This study aims to determine the total flavonoid, phenolic, antioxidant levels of waru extract several The flavonoid content was tested AlCl3 colorimetric method, Folin-Ciocalteu DPPH me...

The genus Hibiscus L. includes several taxa of medicinal value and species used for the extraction of natural dyes. These applications require the use of authentic plant materials. DNA barcoding is a molecular method for species identification, which helps in reliable authentication by using one or more DNA barcode marker. In this study, we have collected 44 accessions, representing 16 species ...

Plants that have potential as alternative food source (floral nectar, pollen and plant tissues) to the boll weevil during the intercropping season were evaluated considering the prevalent conditions of Cerrado in the Central Brazil. Initially, we tested the nutritional adequacy for the survival of the insect of flower resource (pollen and nectar) provided by eight plant species (fennel, mexican...

the cotton leaf roller moth, haritalodes derogata (fabricius, 1775) (lepidoptera: crambidae) was collected on two kinds of flowering shrubs, hibiscus syriacus l. and hibiscus mutabilis l., in rasht, guilan province, during august 2013. this species represents a generic new record for the fauna of iran. a brief description of the species is provided to facilitate the identification.

BACKGROUND The cotton-melon aphid, Aphis gossypii Glover (Hemiptera: Aphididae), is a polyphagous species with a worldwide distribution and a variety of biotypes. North China is a traditional agricultural area with abundant winter and summer hosts of A. gossypii. While the life cycles of A. gossypii on different plants have been well studied, those of the biotypes of North China are still uncle...
