INTRODUCTION: Emamectin benzoate (Proclaim) is an avermectin class insecticide developed for the control oflepidopteron insects. This class of pesticide consists of homologous semi-synthetic macrolides that are derived fromthe natural fermentation products of Streptomyces bacteria. It kills insects by disrupting neurotransmitters, causingirreversible paralysis. It is more effective when ingested, but it also somewhat effective on contact. When sprayed tofoliage, emamectin benzoate penetrates the leaf tissue and forms reservoir within treated leaves, which providesresidual activity against pests that ingest the substance when feeding. Emamectin is widely used in the US and Canadaas an insecticide because of its chloride channel activation properties. It is approved by the EPA for use in preventionof emerald ash borer in ash trees. Emamectin has also shown promising applications in the eradication of fish lice andin fish farming. Emamectin is the 4′′-deoxy-4′′-methylamino derivative of abamectin, a 16-membered macrocycliclactone produced by the fermentation of the soil actinomycete Streptomyces avermitilis. It is generally prepared asthe salt with benzoic acid, emamectin benzoate, which is a white or faintly yellow powder

USAGES: Emamectin iswidely used in controlling lepidopterous pests (order of insects that as larvae are caterpillars and as adults have fourbroad wings including butterflies, moths, and skippers) in agricultural products in the US, Japan, Canada, and recentlyTaiwan. The low-application rate of the active ingredient needed (~6 g/acre) and broad-spectrum applicability as aninsecticide has gained emamectin significant popularity among farmers. Emamectin has been shown to possess agreater ability to reduce the colonization success of engraver beetles and associated wood borers in loblolly pines(Pinus taeda L). A 2006 study regarding bolt-injections of four types of pesticides found emamectin to be the greatestreducer against these species with respect to the amount of larval feeding, length, and number of egg galleries. Awater-soluble preparation of emamectin in polysorbate, acetone, and methanol was shown to prevent the wilting ofJapanese black pine trees inoculated with pine-wood nematodes (Bursaphelenchus xylophilus). Previous treatment ofB. xylophilus infections involved eradicating the local population of Japanese pine sawyers associated with the spreadof the nematode.
