ethiopia is remarkably rich in its biological, ecological and landscape diversity and is home to outstanding natural bio-resources such as a number of herbs, aromatic and medicinal plants. the present study was carried out to study the composition, distribution and economic importance of insect pests of prioritized aromatic (mentha sp., lemon verbena, fennel, rosemary, rosadamascene, oregano, p...

Medicinal and aromatic plants have popular recently to investigate their usability as natural resources in many areas due superior biological activity properties. Hypericum genus contained important medicinal plant species known worldwide. In this study, the ethanol extracts from different parts (flower, leaf stem) of three perforatum, heterophyllum, scabrum were screened for toxicity against a...

the  frequency of  allergic diseases such  as allergic rhinitis is considerable in general population. insect aeroallergens are important allergens which can induce airway inflammation. the aim of this study was to determine the prevalence of sensitization to insect aeroallergens in allergic rhinitis patients in yazd as a desert city in iran. a cross-sectional study was undertaken on 95 allergi...

To repel mosquitoes, there have been many highly effective chemical repellent products, but they carry the potential risk of being unsafe for humans and harmful to environment. Insect products derived from natural sources that are safe environmentally friendly becoming increasingly popular. PMD is a broad-spectrum insect present in small amounts Eucalyptus citriodora essential oil (EO). In this...

The topological model of the Enterobacter cloacae outer membrane protein OmpX showed three putative glycosylation sites. When OmpX was expressed in bacteria that were cultured under aerated conditions, no glycosylation was observed. The coupling of carbohydrate chains to the ompX gene product was also investigated in the eukaryotic baculovirus expression system. For this purpose, a recombinant ...

Biological control is not new, it is simply newly appreciated. This renewed appreciation stems from the widespread insecticide treadmill which is largely a product of insecticide disruption of the balance of insect communities. Biological control is a natural phenomenon; the regulation of plant and animal numbers by natural enemies. In this broad sense, biological control is vital to public hea...

The conotoxin-like (ctx) gene encodes a small cysteine-rich polypeptide in various baculoviruses. Previous research has demonstrated that the product of the ctx gene could be purified from insect cells infected by Autographa californica nuclear polyhedrosis virus (AcMNPV), but its function was unknown. In this paper, we compared the conserved cysteine motif structure (CX3GX2CX5CCX3CX6C) of the ...

Insects of the family Dermestidae are common insect pests of museums and other sites where historical artifacts are displayed and stored. Trogoderma variabile (Ballion), the warehouse beetle, is a member of this family, and though it is more commonly associated with processed and finished stored food products, it can be found in museums. There are aspects relating to monitoring and control of T...

Infectious bursal disease virus (IBDV) capsids are formed by a single protein layer containing three polypeptides, pVP2, VP2, and VP3. Here, we show that the VP3 protein synthesized in insect cells, either after expression of the complete polyprotein or from a VP3 gene construct, is proteolytically degraded, leading to the accumulation of product lacking the 13 C-terminal residues. This finding...
