Puerto Rico Fall Armyworm
The agriculture industry in Puerto Rico constitutes over $800 million or about 0.62% of the island's gross domestic product (GDP) in 2020 . Currently the sector accounts for 15% of the food consumed locally. Experts from the University of Puerto Rico argued that these crops could cover approximately 30% of the local demand, particularly that of smaller vegetables such as tomatoes, lettuce, etc. and several kinds of tubers that are currently being imported. The existence of a thriving agricultural economy has been prevented due to a shift in priorities towards industrialization, bureaucratization, mismanagement of terrains, lack of alternative methods and a deficient workforce. Its geographical location within the Caribbean exacerbates these issues, making the scarce existing crops propense to the devastating effects of Atlantic hurricanes. History Agriculture or farming is concerned with the cultivation of plants, animals and other food sources that sustain life. It also involv ...

Cry1F
Delta endotoxins (δ-endotoxins) are pore-forming toxins produced by ''Bacillus thuringiensis'' species of bacteria. They are useful for their insecticidal action and are the primary toxin produced by Bt maize/corn. During spore formation the bacteria produce crystals of such proteins (hence the name Cry toxins) that are also known as parasporal bodies, next to the endospores; as a result some members are known as a parasporin. The Cyt (cytolytic) toxin group is a group of delta-endotoxins different from the Cry group. Mechanism of action When an insect ingests these proteins, they are activated by proteolytic cleavage. The N-terminus is cleaved in all of the proteins and a C-terminal extension is cleaved in some members. Once activated, the endotoxin binds to the gut epithelium and causes cell lysis by the formation of cation-selective channels, which leads to death. For many years there was no clarity as to the relationship between aminopeptidase N and Bt toxins. Althou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pesticide Resistance
Pesticide resistance describes the decreased susceptibility of a pest population to a pesticide that was previously effective at controlling the pest. Pest species evolve pesticide resistance via natural selection: the most resistant specimens survive and pass on their acquired heritable changes traits to their offspring.PBS (2001)Pesticide resistance Retrieved on September 15, 2007. If a pest has ''resistance'' then the pesticide lacks ''efficacy'' efficacy and resistance are inversely related. Cases of resistance have been reported in all classes of pests (''i.e.'' crop diseases, weeds, rodents, ''etc.''), with 'crises' in insect control occurring early-on after the introduction of pesticide use in the 20th century. The Insecticide Resistance Action Committee (IRAC) definition of insecticide resistance is ''a heritable change in the sensitivity of a pest population that is reflected in the repeated failure of a product to achieve the expected level of control when used accordi ...

CIMMYT
The International Maize and Wheat Improvement Center (known - even in English - by its Spanish acronym CIMMYT for ''Centro Internacional de Mejoramiento de Maíz y Trigo'') is a non-profit research-for-development organization that develops improved varieties of wheat and maize with the aim of contributing to food security, and innovates agricultural practices to help boost production, prevent crop disease and improve smallholder farmers' livelihoods. CIMMYT is one of the 15 CGIAR centers. CIMMYT is known for hosting the world's largest maize and wheat genebank at its headquarters in Mexico. CIMMYT's ninth director general, Bram Govaerts, replaced Martin Kropff in 2021. Other notable scientists like Thomas Lumpkin have served as director general of CIMMYT. Origins The first steps toward the creation of CIMMYT were taken in 1943 when cooperative efforts of the Mexican government and the Rockefeller Foundation led to the founding of the Office of Special Studies, an organiz ...

USAID
The United States Agency for International Development (USAID) is an independent agency of the U.S. federal government that is primarily responsible for administering civilian foreign aid and development assistance. With a budget of over $27 billion, USAID is one of the largest official aid agencies in the world and accounts for more than half of all U.S. foreign assistance—the highest in the world in absolute dollar terms. Congress passed the Foreign Assistance Act on September 4, 1961, which reorganized U.S. foreign assistance programs and mandated the creation of an agency to administer economic aid. USAID was subsequently established by the executive order of President John F. Kennedy, who sought to unite several existing foreign assistance organizations and programs under one agency. USAID became the first U.S. foreign assistance organization whose primary focus was long-term socioeconomic development. USAID's programs are authorized by Congress in the Foreign Assistanc ...

American Society For Microbiology
The American Society for Microbiology (ASM), originally the Society of American Bacteriologists, is a professional organization for scientists who study viruses, bacteria, fungi, algae, and protozoa as well as other aspects of microbiology. It was founded in 1899. The Society publishes a variety of scientific journals, textbooks, and other educational materials related to microbiology and infectious diseases. ASM organizes annual meetings, as well as workshops and professional development opportunities for its members. History ASM was founded in 1899 under the name the "Society of American Bacteriologists." In December 1960, it was renamed the "American Society for Microbiology." Mission ASM's mission is "to promote and advance the microbial sciences." The society seeks to accomplish this mission through: * Publishing highly-cited publications * Running multi-disciplinary meetings * Deploying resources and expertise around the world * Advocating for scientific research * Fost ...

ORCID
The ORCID (; Open Researcher and Contributor ID) is a nonproprietary alphanumeric code to uniquely identify authors and contributors of scholarly communication as well as ORCID's website and services to look up authors and their bibliographic output (and other user-supplied pieces of information). This addresses the problem that a particular author's contributions to the scientific literature or publications can be hard to recognize as most personal names are not unique, they can change ( such as with marriage), have cultural differences in name order, contain inconsistent use of first-name abbreviations and employ different writing systems. It provides a persistent identity for humans, similar to tax ID numbers, that are created for content-related entities on digital networks by digital object identifiers (DOIs). Uses ORCID aims to provide a persistent code for humans, to address the problem that a particular author's contributions to scholarly communication can be hard to r ...

US Mainland
The contiguous United States (officially the conterminous United States) consists of the 48 adjoining U.S. states and the Federal District of the United States of America. The term excludes the only two non-contiguous states, Alaska and Hawaii (also the last ones admitted to the Union), and all other offshore insular areas, such as American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands. The colloquial term "Lower48" is used also, especially in relation to just Alaska (Hawaii is farther south). The related but distinct term continental United States includes Alaska (which is also on the continent of North America but separated from the 48 states by British Columbia and Yukon of Canada), but excludes the Hawaiian Islands and all U.S. territories in the Caribbean and the Pacific. The greatest distance (on a great-circle route) entirely within the contiguous U.S. is 2,802 miles (4,509 km), between Florida and the State of Washington; the ...
