The development of fenvalerate and later esfenvalerate led to the synthesis and commercial marketing of fluvafinate, which is active against spider mites (Hemick et al. 1980). Fuchs synthesized aU of the seven possible fluoro-substituted isomers of cypermethrin (e.g., 2,4,5,6,2, 3 and 4 ) (Hamman and Fuchs 1981). Substitution at the 4 -position produced the most active compound, cyfluthrin. Activity was almost eliminated when chlorine was substituted for fluorine in the 4 -position. Tefluthrin has a higher vapor pressure than most of the other pyrethroids and is active against soil pests such as the com root worm (Jutsum et al. 1986). Bifenthrin is an ester with alcoholic compruients whose activity is not enhanced by an alpha-cyano substituent. Bifenthrin is active against insects (aphids) and mites (Plummer et al. 1983).
