Repellency of Plant Extracts against the Legume Flower Thrips Megalurothrips sjostedti (Thysanoptera: Thripidae).

Megalurothrips sjostedti Trybom is an important pest of cowpea (Vigna unguiculata L.) in Africa. To propose an alternative to chemical control, the repellency of 24 plant extracts was evaluated against adult female thrips of M.

Toxicological and teratological studies of azanidazole.

A toxicological study of 4-[(E)-2-(1-methyl-5-nitro-1H-imidazol-2-yl)-ethenyl]-2-pyrimidinamine (azanidazole, Triclose), a new systemic antitrichomonas agent, was run in laboratory animals in order to evaluate its safety. Studies also covered the effects of azanidazole on reproduction in rats treated prior to mating, on fetal development in rabbits and rats, and on fetal survival and growth in rats treated with it during late pregnancy and lactation. The obtained data indicate that azanidazole was well tolerated when administered as a single dose or repeated daily doses for six months.
