Trapping of small organisms moving randomly : principles and applications to pest monitoring and management by James R Miller( Book )

1 edition published in 2015 in English and held by 5 WorldCat member libraries worldwide

Monitoring traps baited with potent attractants of animals like insects have long played a critical role in revealing what pests are present and when they are active. However, pest managers have been laboring without the tools necessary for quick and inexpensive determination of absolute pest density, which is the cornerstone of pest management decisions. This book fills that gap by demonstrating how catch numbers from monitoring traps can be translated into measures of pests per given area of crop and accurate projections of damage. An unhappy fact of life from the human perspective is that small animals such as insects, mites, mollusks, and nematodes compete severely for our food and fiber. Moreover, some of these creatures vector diseases such as malaria, which kills more than a million humans each year. An imperative of a civilized world is that pests be accurately monitored so that control measures like pesticides are used only when the benefits clearly outweigh the risks to the health of humans, non-target organisms, and the environment.--From electronic record

Responses of lepidoptera to synthetic sex pheromone chemicals and their analogues by W. L Roelofs( )

in English and held by 1 WorldCat member library worldwide

Chemical communication systems are being analyzed at an increasing rate by defining only chemicals involved, or by describing the complex behavioral patterns elicited by some natural chemical mix of unknown composition. With insects, too often the former approach has been prevalent and the behavioral roles of many of the identified chemicals have not been pursued. Many times, however, the possible behavioral functions of a chemical can be inferred from indirect measurements, such as the compound's effect on trap catch. This chapter discusses field trapping and field observation techniques in elucidating sex pheromone responses of lepidoptera, as well as the modulation of these reactions by various chemicals that are not constituents of natural pheromone system
