Bombykol Bombykol Bombykol is a pheromone released by the female silkworm moth to attract mates. It is also the sex pheromone in the wild silk moth ("Bombyx mandarina"). Discovered by Adolf Butenandt in 1959, it was the first pheromone to be characterized chemically. Minute quantities of this pheromone can be used per acre of land to confuse male insects about the location of their female partners. It can thus serve as a lure in traps to remove insects effectively without spraying crops with large amounts of pesticides. Butenandt named the substance after the moth's Latin name "Bombyx mori." "In vivo" it
Ocular larva migrans Ocular larva migrans Ocular larva migrans (OLM), also known as ocular toxocariasis, is the ocular form of the larva migrans syndrome that occurs when "Toxocara canis" (dog roundworm) larvae invade the eye. They may be associated with visceral larva migrans. Unilateral visual disturbances, strabismus, and eye pain are the most common presenting symptoms. The disease presents with an eosinophilic granulomatous mass, most commonly in the posterior pole of the retina. The granulmatous mass develops around the entrapped larva, in an attempt to contain the spread of the larva. ELISA testing of intraocular fluids has been demonstrated to be of great
