Toxicity of Insecticides to Frankliniella invasor (Thysanoptera: Thripidae) Under Laboratory Conditions
This study suggests the use of spinosad and &agr;-cypermethrin as the best control for F. invasor, but these results should be complemented with field evaluations before being recommended to mango growers. Expand
Variable resistance to spinetoram in populations of Thrips palmi across a small area unconnected to genetic similarity
The molecular data indicated high levels of gene flow between populations with different levels of resistance to spinetoram and low gene flow among populations with the same level of resistance, pointing to a likely separate history of resistance evolution. Expand
Geographical and interspecific variation in susceptibility of three common thrips species to the insecticide, spinetoram
Variation in susceptibility of thrips to spinetoram, both among species and among geographical areas, is highlighted, which should help the implementation of management tactics, and they provide insights into the displacement of thrive species in fields. Expand
Diversity of thrips species (Thysanoptera) in fruit orchards in Qazvin province, northwestern Iran
Results of this study showed that Thrips tabaci L. tabaci was found on all species of fruit trees and weeds, and thrips estimated richness was higher in Qazvin county compared to Buin-Zahra and Takestan counties. Expand
Efficacy of Organic Insecticides and Repellents against Brown Marmorated Stink Bug in Vegetables
Although some organically-approved insecticides demonstrate a high level of activity on BMSB in lab bioassays, none of these products appear to be effective at reducing stink bug damage to fruiting vegetables in the field. Expand
Field-evolved resistance to insecticides in the invasive western flower thrips Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) in China.
Spinosad and spinetoram were the most efficient insecticides and are recommended for use in an integrated management programme and should be implemented to reduce the potential for resistance evolving. Expand
Management strategies for western flower thrips in vegetable greenhouses in Iran: a review

Impact of Organic Insecticides on the Survivorship and Mobility of Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) in the Laboratory
This study evaluated the insecticidal efficacy of organically-approved insecticides and experimental biopesticides against adult H. halys in organic production systems and found no measurable difference in the vertical walking distance by surviving individuals between any of the tested materials and the untreated control. Expand
The α6 nicotinic acetylcholine receptor subunit of Frankliniella occidentalis is not involved in resistance to spinosad.
Results indicate that Foα6 is not involved in resistance to spinosad in F. occidentalis, suggesting the G275E mutation does not confer resistance in these populations. Expand


Insecticide Resistance in Field and Laboratory Strains of Western Flower Thrips (Thysanoptera: Thripidae)
Piperonyl butoxide, but not S,S,S-tri-n-butyl phosphorotrithioate, synergized the toxicity of diazinon, bendiocarb, and fenvalerate to KCM thrips, and these thrips were resistant to permethrin, DDT, and imidacloprid but not to amitraz. Expand
Insecticide Resistance in European and African Strains of Western Flower Thrips (Thysanoptera: Thripidae) Tested in a New Residue-on-Glass Test
The results of this bioassay confirm observations from commercial greenhouses of substantial resistance against several groups of insecticides among European and African strains of F. occidentalis and emphasize the need for proper resistance level descriptions of test strains before larger insecticide efficacy screening trials are conducted. Expand
Western Flower Thrips (Thysanoptera: Thripidae) Resistance to Insecticides in Coastal California Greenhouses
Field populations of western flower thrips, Frankliniella occidentalis (Pergande), showed high levels of resistance in laboratory tests to four classes of insecticides Commonly used for insect control in ornamentals, emphasizing the need for better and practical pest management strategies. Expand
Seasonal Patterns of Frankliniella spp. (Thysanoptera: Thripidae) in Tomato Flowers
Western flower thrips, Frankliniella occidentalis (Pergande), has become a pest of tomato in the Southeast by causing direct cosmetic damage to fruit and by transmitting tomato spotted wilt virus.Expand

In order to make experimental studies comparable and statistically meaningful, the article recommends the following formula: per cent control = 100(X - Y)/X, which eliminates errors due to deaths in the control sample which were not due to the insecticide. Expand
Frankliniella occidentalis (Thysanoptera: Thripidae), a Vector of the Tomato Spotted Wilt Virus, with Special Reference to the Color Forms
The two homozygous color forms, pale and dark, of Frankliniella occidentalis (Pergande), the western flower thrips, were demonstrated for the first time to be similarly able to transmit the tomatoExpand
