the use of adjuvants enhances the insecticide efficiency and increases the persistence of insecticides. in this study, the effect of adjuvants on the toxicity of chlorpyrifos and cyhalothrin formulations were investigated under laboratory and field conditions. the comparative toxicity of two chlorpyrifos [(48% emulsifiable concentrate (ec)] formulations (dursban and pyrifos el nasr), two cyhalo...

  Background: German cockroach, Blattella Germanica, is a mechanical vector of various pathogenic agents such as viruses, bacteria, protozoa and parasite eggs. The purpose of this study was to determine the susceptibility level of German cockroach to bendicarb and carbaryl from carbamate insecticides, and malathion and chlropyrifos from organophosphorous insecticides.   Methods: In this study, ...

Thepotatopsyllid,Bactericera cockerelli(Sulc) (Hemiptera:Triozidae), is a seriouspest of potatoes (Solanum tuberosum L.) that can cause yield loss by direct feeding on crop plants and by vectoring a bacterial pathogen, Candidatus Liberibacer psyllaurous. Current pest management practices rely on the use of insecticides to control the potato psyllid to lower disease incidences and increase yield...

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...

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...
