Abstract Systena frontalis (F.) is a major insect pest of nursery production systems in the Midwest, Northeast, and Southeast regions United States. Adults feed on plant leaves, which reduces salability nursery-grown plants. There are limited options available to protect plants from S. adult feeding damage, foliar insecticide applications labor intensive. Systemic insecticides applied growing m...

A solid phase extraction method was developed to isolate four insecticide degradates from baby food that were measured subsequently using high-performance liquid chromatography-tandem mass spectrometry. The degradates [parent insecticide] measured were malathion dicarboxylic acid [malathion], 3,5,6-trichloro-2-pyridinol [chlorpyrifos, chlorpyrifos methyl] (TCPy), cis/trans-3-(2,2-dichlorovinyl)...

A gas chromatographic method was developed for the simultaneous determination of 12 pyrethroids (tefluthrin, bifenthrin, fenpropathrin, cyhalothrin, permethrin, cyfluthrin, cypermethrin, alpha-cypermethrin, flucythrinate, fenvalerate, fluvalinate, and deltamethrin) in tomato puree, peach nectar, orange juice, and canned peas. A miniaturized extraction-partition procedure requiring small amounts...

Myzus persicae (Sulzer) (Hemiptera: Aphididae) is a polyphagous pest that causes significant losses in many crops. In the present study, biochemical and molecular mechanism of acetamiprid resistance laboratory-selected population which ratios reached 57.5-fold were investigated. This study was conducted Isparta University Applied Sciences, Agriculture Faculty, Department Plant Protection 2018 2...

the susceptibility of 5 wild strains of german cockroach collected from five infected flats in tehran were assessed by tests of surface contact method to cyfluthrin, permethrin, sumithrin and lambdacyhalothrin. comparison of the result of knockdown tests on the wild strains with a standard susceptible strain indicated that all the strains are resistant to sumithrin, i.e., resistance ratio, the ...

background: anopheles mosquitoes are an important group of arthropods due to their role in transmission of ma­laria. the present study was conducted for determination of susceptibility status of anopheles stephensi to different imagicides collected from malarious area in chabahar city, iran. methods: in the present study seven insecticides including: ddt 4%, lambdacyhalothrin 0.05%, deltamethri...

Mosquitoes characteristically feed on plant-derived carbohydrates and honeydew just after emergence and intermittently during their lives. Development of toxic baits focusing on this carbohydrate-seeking behavior may potentially contribute to localized control. In the present study, ten insecticides were fed to female Culex quinquefasciatus, Anopheles quadrimaculatus, and Aedes taeniorhynchus i...
