The expense and ineffectiveness of drift-based insecticide aerosols to control dengue epidemics has led to suppression strategies based on eliminating larval breeding sites. With the notable but short-lived exceptions of Cuba and Singapore, these source reduction efforts have met with little documented success; failure has chiefly been attributed to(More)
The importance of honey bees to the world economy far surpasses their contribution in terms of honey production; they are responsible for up to 30% of the world's food production through pollination of crops. Since fall 2006, honey bees in the U.S. have faced a serious population decline, due in part to a phenomenon called Colony Collapse Disorder (CCD),(More)
Energy distribution networks refer to that part of the electricity network that delivers power to homes and business. It is reported that significant amounts of energy are being wasted simply due to inefficiencies in this network. Further, this domain is rapidly changing with new types of loads such as electric vehicles or the spread of new types of energy(More)
BACKGROUND Honey bees are an essential component of modern agriculture. A recently recognized ailment, Colony Collapse Disorder (CCD), devastates colonies, leaving hives with a complete lack of bees, dead or alive. Up to now, estimates of honey bee population decline have not included losses occurring during the wintering period, thus underestimating actual(More)
Here we describe a new phenomenon, entombed pollen, which is highly associated with increased colony mortality. Entombed pollen is sunken, capped cells amidst "normal", uncapped cells of stored pollen, and some of the pollen contained within these cells is brick red in color. There appears to be a lack of microbial agents in the pollen, and larvae and adult(More)
Sporozoite data from salivary gland dissections are presented that clearly incriminate Anopheles trinkae, An. pseudopunctipennis, An. sp. near fluminensis, An. oswaldoi, An. nuneztovari and An. rangeli as vectors of malaria parasites in the Rio Ene Valley, a hyperendemic malarious area in Junin Department, eastern Peru. Anopheles trinkae is considered the(More)
In April of 1977 an outbreak of falciparum malaria occurred among the Mayongong Indians, located at Uauaris in the Territory of Roraima, Brazil. Blood specimens from 157 Indians were examined for Plasmodium; 62 were found to be infected. In three cases the infection was not cured with chloroquine but responded favorably to the drug combination of(More)
