Tetrapteris

One group of compounds that has demonstrated significant toxic effects on some pests of modern man have been discovered in the neem tree (Azadirachta indica) (A. Juss.). The most active constituent, azadiractin (AZA), a triterpenoid, has been shown to have properties including feeding and ovipositional deterrence, repellency, growth disruption, reduced fitness, and sterility in a number of species of hemimetabolous and holometabolous insects (Ascher and Meisner 1989; Shmutterer 1990). Research has been focused on controlling agricultural pests as well as medically important arthropods with products derived from neem.Much more at http://www.colostate.edu/Depts/Entomology/courses/en570/papers_1996/panella.html
