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...

We investigated the accumulation of pesticide residues on rubber latex gloves that are used by strawberry harvesters to protect their skin, reduce pesticide exposure and promote food safety. Gloves accumulated residues of 16 active ingredients including azoxystrobin, bifenthrin, boscalid, captan, cyprodinil, fenhexamid, fenpropathrin, fludioxonil, hexythiazox, malathion, methomyl, naled, propic...

Since the 1990s, insect growth regulator pyriproxyfen and pyrethroids such as fenpropathrin have been widely used to reduce pest populations in agriculture. The widespread use of these insecticides makes it essential for researchers understand how they behave terrestrial ecosystems can be detected. This work reviewed most effective analytical techniques detect various samples. degradation soil ...

Citrus leprosis mite is an important pest to Brazilian citriculture. Due the potential damage caused by virus transmitted this mite, synthetic acaricides are main management strategy used citrus growers reduce vector population. The current review aims provide historical data on use of control and factors involved with efficacy these products. To get know products that were have been we scienti...

In a laboratory investigation, the effect of spray droplet size on the mortality of three life stages (eggs, nymphs, and adults) of the Asian citrus psyllid (ACP), Diaphorina citri Kuwayama, was determined. Six spray droplets of nearly uniform size (diameter) ( D10 1⁄4 40:5, 52.0, 101.5, 147.9, 174.0, and 264.7 lm) of fenpropathrin, a synthetic pyrethroid, were generated using a piezo-electric ...

Eusocial Apis mellifera colonies depend on queen longevity and brood viability to survive, as the is sole reproductive individual maturing replenishes shorter-lived worker bees. Production of many crops rely both pesticides bee pollination improve crop quantity quality, yet sublethal impacts this pesticide exposure often poorly understood. We investigated resiliency queens their after one month...
