Introduction: Organic antibacterial materials have been used as insecticides and bactericides for many years. Unfortunately, high temperatures in manufacturing process reduce their antibacterial properties. However, inorganic materials of antibacterial agents have excellent bacterial resistance and thermal stability. Over the past few decades, inorganic nanoparticles whose structures exhibit si...
After more than 70 years of chemical pesticide use, modern agriculture is increasingly using biological control products. Resistances to conventional insecticides are wide spread, while those to bio-insecticides have raised less attention, and resistance management is frequently neglected. However, a good knowledge of the limitations of a new technique often provides greater sustainability. In ...
Insect predators in North America suppress Aphis glycines Matsumura (Hemiptera: Aphididae) populations; however, insecticides are required when populations reach economically damaging levels. Currently, insecticides used to manage A. glycines are broad-spectrum (pyrethroids and organophosphates), and probably reduce beneficial insect abundance in soybean, Glycine max (L.) Merr. Our goal was to ...
BACKGROUND Honey bees (Apis mellifera L.) are among the most important pollinators in natural and agricultural settings. They commonly encounter insecticides, and the effects of insecticides on honey bees have been frequently noted. It has been suggested that honey bees may be (as a species) uniquely sensitive to insecticides, although no comparative toxicology study has been undertaken to exam...
Head louse infestation, or pediculosis capitis, caused by Pediculus humanus var. capitis, is a common health concern in pediatric age group. An itching of the scalp is the chief symptom, whereas presence of viable nits confirms the diagnosis of head louse infestation. Secondary bacterial infection with impetignization with cervical and occipital lymphadenopathy can complicate the clinical scena...
Introduction: Malaria is still an important health problem in southern Iran. Anopheles stephensi is one of the most important vectors of malaria, especially in urban areas. Because of long time of chemical insecticides against vectors in endemic areas and their potential resistance to such chemicals, it is necessary that vectors continuously to be assessed against susceptibility level. We...
Introduction: An estimated population of 40% of Hormozgan province, southern Iran, live mainly in mountainous areas in close contact with Anopheles Fluviatilis. This specie has highly exophilic and anthropophilic behaviors and is one of major malaria vectors in the mountainous areas of Hormozgan province. This study was conducted to assess the irritability and susceptibility level of An. Fluv...
The effects of agrochemicals pollution on soil nutrients, microbes as well plants cultivated the were studied. Insecticide and herbicide used to impact samples across concentration gradients. Bean maize seeds planted in separate experiments monitor plants. microbial diversity physicochemical characteristics before after determined using standard methods. Chlorophyll contents leaves also plantin...
This work examines the feasibility of liquid chromatography/mass spectrometry (LC/MS) time-of-flight (TOF) in conjunction with LC/MSD ion trap to analyze chloronicotinyl insecticides: acetamiprid, imidacloprid, and thiacloprid, in four salad vegetables: tomatoes, peppers, lettuce, and cucumbers. Included in this report are the LC/MSD TOF and LC/MSD Trap spectra of the three chloronicotinyl inse...
