Among insect pests the Green peach aphid Myzus persicae (Sulzer) is one of the most damaging virulent insect to potato crop. Research experiment was conducted at Research Farm of Khyber Pakhtunkhwa Agricultural University Peshawar, Pakistan during spring 2008 to test two insecticides against Myzus persicae on two potato varieties viz Kuroda and Desiree. The results revealed that both the insect...

BACKGROUND Multiple applications of pyrethroid insecticides are used to manage European corn borer, Ostrinia nubilalis Hübner, in snap bean, but new diamide insecticides may reduce application frequency. In a 2 year small-plot study, O. nubilalis control was evaluated by applying cyantraniliprole (diamide) and bifenthrin (pyrethroid) insecticides at one of three phenological stages (bud, bloom ...

Adult tomato psyllid, Bactericerca (Paratrioza) cockerelli (Sulc) (Homoptera: Psyllidae), behavioral responses were evaluated for five tomato plant lines and for the interactions of insecticides with four commercial cultivars. Plant lines tested included the commercial 'Shady Lady', 'Yellow Pear', '7718 VFN', 'QualiT 21', and the plant introduction line PI 134417. Insecticides included a kaolin...

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...

As supplements to classical chemical insecticides, two approaches to develop recombinant baculovirus insecticides are described. In one approach an insect-specific toxin is expressed leading to a dramatic reduction in time to death. In the second approach an insect juvenile hormone esterase is expressed which leads to a reduction in feeding. Modifications of the wildtype esterase led to viruses...

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...
