The livestock protection collar (LP Collar) i: one of the few technical innovation: developed over the past 20 years fog managing coyote depredation on livestock Invented by Roy McBride in 1970, the LF Collar was researched at length by the Denver Wildlife Research Center (DWRC; and several cooperators before being approved for use with Compound 1080 by the U. With this transfer, the LP collar ...

In response to a predator attack, many Aphidinae species release an alarm pheromone, which induces dispersal behavior in other individuals within the colony. The major component of this pheromone is the sesquiterpene (E)-β-farnesene (Eβf), but variations occur between aphid species. In the present work, we collected, identified, and quantified the alarm pheromone of Aphis craccivora Koch (Hemip...

Aphids are a worldwide pest and an important model in ecology and evolution. Little is known, however, about the genetic structure of their colonies at a microgeographic level. For example, it remains largely unknown whether most species form monoclonal or polyclonal colonies. Here, we present the first detailed study on levels of clonal mixing in a nonsocial facultative ant mutualist, the blac...

The Virginia Cooperative Coyote Control Program was created in 1990 to address increasing livestock losses to coyotes and the inability of producers to solve such problems themselves. The eastern coyote arrived in Virginia in the late 1970s or early 1980s. Lobbying efforts of agricultural groups, such as the Virginia Sheep Federation, helped create a cost-share program administered by the Virgi...

Seasonal dispersal and diversity of aphid species were monitored on pepper farms in St. Catherine, Jamaica throughout 1998 and 1999 to identify the most likely vectors of tobacco etch virus (TEV) in pepper Þelds. Flight activitywasmonitoredweekly on Þve farms usingwater pan traps. More than 30 aphid species were identiÞed, 12 of which are new records for Jamaica. Ninety-two percent of the aphid...
