  • Predicting impacts of global warming on population dynamics and distribution of arthropods in Japan

    The mean surface temperature rose by 1.0°C over the last 40 years in Japan. Changes in the pest status, distribution range, winter mortality, and the synchronization in phenology were examined. The increase in the number of annual generations of each taxon was predicted based on the lower developmental threshold and the thermal constant. Increasing damage due to rice- and fruit-infesting bugs, ...

  • Root-knot nematode-resistant alfalfa suppresses subsequent crop damage from the nutsedge-nematode pest complex

    Southern root-knot nematode [RKN, Meloidogyne incognita (Kofoid & White) Chitwood], yellow nutsedge (YNS, Cyperus esculentus L.), and purple nutsedge (PNS, C. rotundus L.) occur together as a mutually beneficial pest complex in sandy soils. All crops grown in infested soils are affected due to the wide host range of the nematode, the perennial life cycle of the nutsedges, their interactions, ...

  • Climatic and intertrophic effects detected in 10-year population dynamics of biological control of the arrowhead scale by two parasitoids in southwestern Japan

    Relative effects of weather and three-trophic interactions were studied for a classical biological control system consisting of the arrowhead scale Unaspis yanonensis, known formerly as a serious pest of the Satsuma mandarin orange Citrus unshiu, and its two introduced parasitoids, Coccobius fulvus and Aphytis yanonensis. Yearly population responses of the three insect species on a per-tree basis ...

  • Environmental impact of an orchard winter wash and early season pesticide applications on both a beneficial and a pest mite species in Bramley apple orchards

    Apple orchards often receive winter-washes to help aid invertebrate pest control. These can have detrimental environmental consequences. The application of winter-wash increased Aculus schlechtendali numbers while a decrease in numbers of the beneficial mite Anystis baccarum was observed. The application of early season pesticide treatments produced mixed results in relation to A. schlechtendali. ...

  • Developing a National Tiger Action Plan for the Union of Myanmar

    Abstract  A century ago, tigers were considered pests in Myanmar. Hunters claimed thousands, yet populations persisted. In the past century, because of habitat loss and prey depletion, coupled with the recent demand for traditional medicines, tiger populations have been reduced to a few hundred individuals. As a first step toward long-term planning for tigers, and to guide efforts to ...


  • Climate change and human health in Latin America: drivers, effects, and policies

    Abstract  Many people would be increasingly affected by living under critical conditions in Latin America if, as expected, global warming aggravates disease and pest transmission processes. Heat waves and air pollution would increase heat-related diseases and illness episodes in large cities. Fire smoke has been associated with irritation of the throat, lung and eyes, and respiratory ...


  • Malaysian manufacturer battles bird droppings - Case Study

    Corrosive bird droppings from a huge pest bird infestation were compromising safety and sanitation at a major Malaysian chemical plant.  Here is how Bird-X products solved their complex bird problem.

  • The DNA of the U.S. Regulatory System: Are We Getting It Right For Synthetic Biology?

    U.S. regulatory oversight of synthetic biology across the board needs to be modernized to reflect and address the promising technologies routinely entering the market. From a statutory perspective, the pertinent laws appear sufficiently broad to empower federal agencies to address potential risks and promote the potential benefits of synthetic biology. The regulatory infrastructure, however, is ...

  • Controlling Barnyardgrass with Corn Hybrid Selection

    Barnyardgrass is a summer annual grass weed with a global impact on corn production.  Yield losses due to barnyardgrass competition have been estimated up to 45% or more for crops such as cotton and corn. Besides corn, it can also be a serious weed pest in rice, soybean, sugarbeet, cotton, and corn. Integrated weed management techniques can be used for control of barnyardgrass in corn. High ...

  • Why Eating Invasive Species Is a Bad Idea

    Gastronomy is no silver bullet for controlling invasive species. It seems like whenever an edible animal becomes an invasive pest, someone suggests that getting people to eat it will solve the problem. For instance, in 1998 the state of Louisiana induced famous New Orleans chefs to develop recipes for nutria, which ...

  • Composting - Best bang for MSW management buck

    For many years, life cycle analyses of end-of-life management practices have been available for all of the basic recyclables as well as organics. The life cycle data, usually derived by the US Environmental Protection Agency's Waste Reduction Model (WARM), represents the net greenhouse gas impact of recycling, landfilling or incinerating a variety of material streams. The model calculates ...
