This study investigated the effects of the permethrin-impregnated plastic on ant mortality and foraging rates, and tested its potential for preventing ants from colonizing potted soil. Direct exposure to the plastic for as short as 1 min caused significant mortality of both red imported fire ants, Solenopsis invicta Buren, and Argentine ants, Linepithema humile (Mayr); however, red imported fir...

We study families of normal-form games with fixed preferences over pure action profiles but varied preferences over lotteries. That is, we subject players’ utilities to monotone but non-linear transformations and examine changes in the rationalizable set and set of equilibria. Among our results: The rationalizable set always grows under concave transformations (risk aversion) and shrinks under ...

We review the results from a 20-year study of the spread of the invasive Argentine ant, Linepithema humile (MAYR, 1868), in a reserve in Northern California. Ecological studies show that Argentine ants disrupt native ant communities. The best predictor of Argentine ant distribution is proximity to human disturbance, because buildings and irrigation provide water in the dry season and warm, dry ...

background: evaluating the significance and the effects of plant-derived drugs on laboratory animal’s fertility was recognized. there was antioxidant activity reported from heracleum persicum (golpar).objective: current study aims to study the antioxidant effect of golpar extracts on sperm parameters and chromatin quality in mice.materials and methods: eighteen adult male mice were divided to 3...

Bio-inspired techniques are used for synthesis in terms of application, green chemical research, facile, and eco-friendly chemistry study silver nanostructures utilizing plant extracts as natural reducing/stabilization solid adjuvants without the use toxic damaging reagents. The present investigates biosynthesis Ag nanoparticles via mediation methanolic extract Heracleum persicum seeds, any sta...
