Flower thrips are one of the key pests in production of southern highbush blueberries (Vaccinium corymbosum L. × V. darrowi Camp). They feed on the reproductive parts of the flower and reduce yield. Very few insecticides are available to manage thrips population. Therefore, it is necessary to evaluate pre-existing and experimental insecticides for their efficacy against thrips. There is also a ...

BACKGROUND According to the national strategy plan on monitoring of insecticides resistance, this study was carried out to determine the base line susceptibility of the Culicidae mosquitoes to the WHO-recommended insecticides in an endemic focus of malaria in southeastern Iran. METHODS Larval collection was carried out by dipping method and adult collection occurred by suction tube from Janua...

Different insecticides are being used for household and agricultural pest control in the capital city of Iran, Tehran. An investigation was carried out in order to evaluate the susceptibility level of laboratory and field collected mosquito, Culex quinquefasciatusin to different insecticides. Field strain was collected from sewage system of the city. Adult females were subjected to the diagnost...

Increasing insecticide resistance requires strategies to prolong the use of highly effective vector control compounds. The use of combinations of insecticides with other insecticides and phytochemicals is one such strategy that is suitable for mosquito control. In bioassays with Aedes aegypti and Culex annulirostris mosquitoes, binary mixtures of phytochemicals with or without synthetic insecti...

BACKGROUND AND OBJECTIVES Kahnooj district in south of Iran is an endemic area for malaria where Anopheles stephensi (Liston) is a main malaria vector and An. dthali (Patton) a secondary vector. According to the national strategy plan on monitoring of insecticides resistance, this study was performed on susceptibility and irritability levels of An. stephensi and An. dthali to different insectic...

background: the german cockroach, blattella germanica l . , is a serious household and public health pest worldwide. con­trol of this species has been very difficult to achieve. toxicity of cypermethrin ec10%, deltamethrin ec5%, diazi­non ec0.5%, lambda-cyhalothrin ec5% and negon® (permethrin+propoxur oil liquid1%) commercial for­mula­tions were investigated against adult males of german cockro...

the potato tuber moth (ptm), phthorimaea operculella (zeller) is one of the important pests of potato in tropical regions. in this research, the toxicity of two insecticides, abamectin and deltamethrin on p. operculella was studied at 26 ± 1 c°, 65 ± 5% rh and photoperiod of 16:8 h (l: d). the concentrations were determined by preliminary dose setting experiments. distilled water was used as co...

Systemic insecticides are compounds that may be applied to plants as a foliar spray or to the soil/ growing medium as a drench or granules. These materials are absorbed by roots or into other tissues and then translocated to plant parts. This may then protect plants from damage associated with phloem-feeding insects such as the Hemipterans including aphids, whiteflies, mealybugs, and soft scale...

malaria has recently been resurged in some parts of iran which is bordered with armenia, naxcivan and turkey. an attempt was made to asses the current status of insecticide resistance in the main malaria vector , an.sacharovi. adult engorged mosquitoes were collected from dwellings during the seasonal activity of the vector, which is synchronized in summer 2001. mosquitoes were subjected to the...

background: we aimed to evaluate different fibres of bednets impregnated with various pyrethroids. the stability of insecticide on the bednet was measured using different methods of washings as well as local made detergents. methods: the entire test was carried out according to the who-recommended methods. in addition, the impact of the numbers of washes on the stability of the insecticides was...
