status of indoor residual spraying by deltamethrin in malaria elimination program, southeastern iran
abstract background: iran is one of the countries implementing indoor residual spraying (irs) for malaria control. deltamethrin (dlt) is one of the insecticides recommended by world health organization (who) for this program. irs is currently performed in sistan and baluchistan province as an area with unstable malaria situation and the highest prevalence of malaria in the country. dlt has been...
Pathogenicity and virulence of entomogenous fungus, Verticillium lecanii, was studied on the pea aphid, Acyrthosiphon pisum. Vertalec, a commercial product of V. lecanii, was evaluated under controlled conditions. Second instar nymphs were inoculated with conidial suspensions at concentrations ranging from 104 to 108 conidia/ml, and sterile distilled water (containing wetting agent) as control,...
اندازهگیری تغییرات باقیمانده قارچکش متالاکسیل در خیار تولید شده تحت شرایط گلخانههای صنعتی و سنتی
Vegetable crops are exposed to repeated spraying against the pests and diseases during the growing sessions. Crops such as greenhouse cucumber are usually harvested a short time after spraying, bearing a high level of pesticides with them. This fact justifies a research on this problem. This research was carried out to determine the effects of metalaxyl (a fungicide commonly used in greenhouse)...
INTRODUCTION Attractive Toxic Sugar Baits (ATSB) is a new vector control method that meets Integrated Vector Management (IVM) goals. In an experimental design, this study aimed to determine effects of ATSB on control of Phlebotomus papatasi, as a main vector of Zoonotic Cutaneous Leishmaniasis (ZCL), in Qom Province, center of Iran. METHODS In a cross-sectional design, boric acid was mixed wi...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
Since more than 75% of the rice fields in Iran are located in the Northern provinces i.e. Mazandaran, Guilan, and Golestan identifying the crop water requirement of rice fields is essential for water resources planning in the Northern provinces. The objective of this research was to ascertain the crop water requirement of two rice cultivars namely Hashemi and Khazar in Guilan province during...
Spraying estradiol-1713, progesterone or norethisterone intranasally in adult male rhesus monkeys (7.5-11 kg BW) at a daily dose of 30 pg/day for a period of 60 days resulted in a decrease of testicular size, arrest of spermatogenesis and a significant reduction in serum levels of testosterone. No changes were observed in the solvent-treated controls.
In view of the uneven artificial sowing, low sowing, as well as the fact that the existing seeders cannot meet the sowing requirements of Pteris vittata, this paper designed an automatic plug seeder by using the method of spraying and sowing after mixing spores and water. In order to obtain the optimum working parameters of the seeder, response surface method (RSM) was employed to desi...

The manuscript describes a study on the blood cholinesterase (ChE) level in an exposed population at different interval of time after spraying with malathion suspension (SRES) use for kala-azar vector control in an endemic area of Bihar, India. The toxicity of a 5% malathion formulation in the form of a slow release emulsified suspension (SRES) was assessed by measuring serum ChE levels in spra...
