Cyfluthrin is a pyrethroid insecticide and common household pesticide. It is a complex organic compound and the commercial product is sold as a mixture of isomers . Like most pyrethroids (MoA 3a), [ 1 ] it is highly toxic to fish and invertebrates , but it is far less toxic to humans. [ 2 ]
Over the subsequent decades these derivatives were followed with other proprietary compounds such as fenvalerate, lambda-cyhalothrin and beta-cyfluthrin. Most patents have now expired, making these compounds cheap and therefore popular (although permethrin and fenvalerate have not been re-registered under the 91/414/EEC process).
Bifenthrin is poorly soluble in water and often remains in soil. Its residual half-life in soil is between 7 days and 8 months, depending on the soil type, with a low mobility in most soil types. Bifenthrin has the longest known residual time in soil of insecticides currently on the market. It is a white, waxy solid with a faint sweet smell.
The table shown on the right can be used in a two-sample t-test to estimate the sample sizes of an experimental group and a control group that are of equal size, that is, the total number of individuals in the trial is twice that of the number given, and the desired significance level is 0.05. [4]

Since then, many BPUs were commercialised by many companies. BPUs accounted for 3% of the $18.4 billion world insecticide market in 2018. [4] They are active against types of insect pests, (e.g. lepidoptera coleoptera, diptera) in agriculture, [7] [1] as well as being used against termites and animal health pests such as fleas. [8]
Tefluthrin is the ISO common name [3] for an organic compound that is used as a pesticide.
