In order to improve the chemical control of diamondback moth, Plutella xylostella (L), in Taiwan, the Taiwan Agricultural Research Institute organized in 1980 a program aimed at analyzing the insecticide resistance and mode of action. After almost five years of study, we have gathered information on the sampling method, resistance, cross resistance, the mode of insecticide action, and the effic...

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...

Abstract Background ( R )-(+)-perillyl alcohol is a naturally oxygenated monoterpene widely used as the natural flavor additives, insecticides, jet fuels and anti-cancer therapies. It was also readily available precursors. However, this product present at low concentrations from plant sources which are not economically viable. Therefore, alternative microbial production methods rapidly emerging...
