An analysis of the hazards acompanying the aerial application of toxic pest-control chemicals is presented. The nature of the chemicals, the symptoms of toxicity, recommended treatment, and suggestions for safe-handling, are discussed. The introduction of the chlorinated, cyclic hydrocarbons for large-scale use as agricultural insecticides somewhat less than two decades ago, marked the beginnin...

ABSTRACT.-Parasites may affect host behavior in a number of ways, including their locomotory performance. We investigated whether the number of holes produced by the feather louse (Myrsidea rustica) affected flight behavior in adult male Barn Swallows (Hirundo rustica) by video-taping flight performance of individuals during escape and level flight.

BACKGROUND The purpose of this study was to examine the effect of a leaf extract from A. archangelica on the growth of Crl mouse breast cancer cells in vitro and in vivo. MATERIALS AND METHODS The antiproliferative activity of the extract was measured by 3H-thymidine uptake in the Crl cells in vitro. Twenty mice were injected with the Crl cells, and 11 of them were fed A. archangelica leaf ex...
