Fenvalerate is an insecticide. It is a mixture of four optical isomers which have different insecticidal activities. The 2-S alpha (or SS) configuration is the most insecticidally active isomer. Fenvalerate consists of about 23% of this isomer.
Fenvalerate is an insecticide of moderate mammalian toxicity. In laboratory animals, central nervous system toxicity is observed following acute or long-term exposure. Fenvalerate has applications against a wide range of pests. Residue levels are minimized by low application rates. Fenvalerate is most toxic to bees and fish. It is found in some emulsifiable concentrates, ULV, wettable powders, slow release formulations, insecticidal fogs, and granules. It is most commonly used to control insects in food, feed, and cotton products, and for the control of flies and ticks in barns and stables. Fenvalerate does not affect plants, but is active for an extended period of time.
Fenvalerate may irritate the skin and eyes on contact, and is also harmful if swallowed.

Holaaa, ya te comenté en otra web que esta serie tuya de termitas es impresionante. Yo tengo también una foto en mi galería sobre este insecto, pero sin tu nivel de calidad.
Un abrazo desde españa y buena semana:

uou... that insecticide is... brrrr.
I was wondering why the bugs put their legs up to the sky when they´re dead...
Anyway, great macro over the termite. Good light, details and POV.
TFS, have a nice day!
