BackgroundNatural silk is one of the best yarns that attract large number of users and become a very important industry. Mulberry leaves is a natural food of silkworm, therefore scientists have recently incorporated methods for increasing production of silk. These methods use the insect growth regulators (IGRs) or similar peptide hormones and amino...

The parasitoid species Cotesia vestalis (Haliday) (Hymenoptera: Braconidae) is an important parasitoid, mass multiplied and used against the diamondback moth Plutella xylostella (Linneaus) (Lepidoptera: Plutellidae) worldwide. The present study was carried out to investigate the effect of host larval instars on parasitism and fitness to determine t...

Dans le domaine de la microbiologie, de nombreuses expériences se basent sur une fine observation des micro-organismes. De par leur intérêt dans le développement de procédés agroalimentaires modernes, il est important d’étudier leur développement et leur taux de survie dans des conditions environnementales spécifiques telles que des stress osmotiqu...

ABSTRACT The gregarious endoparasitoid Tetrastichus giffardianus Silvestri (Hymenoptera: Eulophidae) is a natural enemy of fruit flies. This parasitoid was previously used to successfully control Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) in Hawaii, USA. Despite its importance in the control of fruit fly pests, little is known about the ...

BECN1 is a haploinsufficient tumor suppressor gene that is monoallelically deleted or epigenetically silenced in many human cancers. In breast cancer, 40% of tumors exhibit monoallelic deletion of Beclin 1. Additionally, low Beclin 1 mRNA expression is observed in aggressive breast cancer subtypes and reduced expression is an independent predictor ...

California condors consume non-food items, including anthropogenic waste, and provision it to their young. Consuming “microtrash” can cause mortality, especially in nestlings. There are several hypotheses explaining why condors might consume microtrash. These hypotheses assume condors exhibit a preference for the type of material. Therefore, we tes...

The scutellerid shield bug, Deroplax silphoides (Thun.) (Hemiptera: Scutelleridae), is a new recorded insect species (in Egypt) attacking the ornamental plant, Dodonaea viscosa (L.). The bug feeds by sucking sap from flowers and green seeds of this plant and sometimes from the very tender young apical leaves. Abundance of both the bug and its assoc...

In cells undergoing stress, the p53 transcription factor is stabilized and activates the expression of numerous genes contributing to p53-mediated tumor suppression. One p53 target gene is Mdm2, which encodes an oncoprotein that binds and ubiquitinates p53 for proteasomal degradation, thus limiting the amplitude and duration of the p53-mediated str...
