The cotton bollworm (CBW), Helicoverpa armigera Hübner (Lepidoptera: Noctuidae), and cotton aphid (CA), Aphis gossypii Glover (Hemiptera: Aphididae), are two cotton pests that are commonly found throughout the world. A weekly sampling program was established to determine the spatial distribution of A. gossypii and H. armigera in cotton fields. Spat...

On March 2019 a severe flood episode inundated large agricultural areas of Golestan province, in northern Iran. In this study, we assessed the impacts of the flooding episode on cotton bollworm, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae). To do so, a network of pheromone-bait traps distributed throughout Golestan was installed and used...

Tetranychus urticae Koch (Acari: Tetranychidae) is a serious pest in cotton fields worldwide. Monitoring of T. urticae with time-series of vegetation index and climatic factors based satellite data was applied to near real-time assessing. The current study aimed to determine correlations between T. urticae population dynamic and effects of Aerosol...

Cotton bollworm, Helicoverpa armigera Hübner (Lepidoptera: Noctuidae), is one of the most important and key pests of cotton in Iran. This study was carried out with the aim of investigating the efficacy of several different insecticides on cotton bollworm in three regions of Golestan province, Iran, in a completely randomized design with 4 replicat...

Scorpion venom is a rich source of toxins which have great potential to develop new therapeutic agents. Scorpion chloride channel toxins (ClTxs), such as Chlorotoxin selectively inhibit human Matrix Methaloproteinase-2 (hMMP-2). The inhibitors of hMMP-2 have potential use in cancer therapy. Three new ClTxs, meuCl14, meuCl15 and meuCl16, derived fro...

Scorpions are generally an important source of bioactive components, including toxins and other small peptides as attractive molecules for new drug development. Mesobuthus eupeus, from medically important and widely distributed Buthidae family, is the most abundant species in Iran. Researchers are interesting on the gland of this scorpion due to th...

Entomology Journal publishes original research papers and reviews from any entomological discipline or from directly allied fields in ecology, behavioral biology,

Nanotechnology-based drug delivery systems have been used to enhance bioavailability and biological activities. Chitosan incorporating curcumin can serve as a biocompatible substitute for metallic nanoparticles in preventing biofilm formation of Streptococcus mutans and plaque on teeth. The interactions between chitosan nanoparticle as a carrier an...

Aptamers (ss-DNA or ss-RNA), also known as artificial antibodies, have been selected in vitro median to bind target molecules with high affinity and selectivity. Diazinon is one of the most widely used organophosphorus insecticides in developing and underdeveloped countries as insecticide and acaricide. Diazinon is readily absorbed from the gastroi...

Pesticide detection is a main concern of food safety experts. Therefore, it is urgent to design an accurate, rapid and cheap test. Biosensors that detect pesticide residues could replace current methods, such as HPLC or GC-MC. This research designs a biosensor based on aptamer (Oligonucleotide ss-DNA) in the receptor role, silver nanoparticles (AgN...

In order that removal of excess fluoride from water a novel magnetic nanocomposite has been synthesized. Magnetic nanoparticles were successfully synthesized by chemical coprecipitation method. Afterwards, polyaniline containing magnetic nanoparticles were prepared by in-situ doping polymerization in the presence of HCl. The polyaniline/Fe3O4 magne...

Searching capacity is of great importance in the efficiency of natural enemies. In this research, the host-stage preference and functional response of Diaeretiella rapae (McIntosh) to different densities of greenbug, Schizaphis graminum (Rondani) were determined on Pishtaz wheat leaves at 25 ± 1°C, 60-70% relative humidity, and a photoperiod of 16:...
