Boll Weevil Eradication Program
The Boll Weevil Eradication Program is a program sponsored by the United States Department of Agriculture (USDA) which has sought to eradicate the boll weevil in the cotton-growing areas of the United States. It's one of the world's most successful implementations of integrated pest management. The program has enabled cotton farmers to reduce their use of pesticides by between 40-100%, and increase their yields by at least 10%, since its inception in the 1970s. By the autumn of 2009, eradication was finished in all US cotton regions with the exception of less than one million acres still under treatment in Texas. History Since its migration from Mexico in the late 19th century, the boll weevil had been the single most destructive cotton pest in the United States, and possibly the most destructive agricultural pest in the United States. The cost of its crop depredations has been estimated at $300 million per year. The control measures used have included a wide range of pesticides, ...

Leo Dale Newsom
Leo Dale Newsom (23 February 1915 – 10 October 1987) was an American entomologist and specialist on crop pest management particularly in cotton and soybean cultivation and was known for his approaches to Integrated Pest Management. Newsom's was born in Shongaloo, where his father was a cotton farmer and his mother was a teacher. He went to the local high school and grew up with an interest in dogs and hunting. In 1936 he went to study at the Louisiana Technological University where he became interested in entomology. He moved to Louisiana State University and obtained a BS in 1940 while also becoming a college boxing champion. He then went to Cornell University but the war interrupted his studies, and he joined the US Army Medical Corps in 1942 working on mosquito and louse control. He returned to Cornell in 1946 and received his PhD with studies on "The Biology and Economic Importance of the Clover Root Borer, '' Hylastinus obscurus'' (Marsham)" in 1947. His contemporaries incl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Lakes
The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes in the mid-east region of North America that connect to the Atlantic Ocean via the Saint Lawrence River. There are five lakes, which are Lake Superior, Superior, Lake Michigan, Michigan, Lake Huron, Huron, Lake Erie, Erie, and Lake Ontario, Ontario and are in general on or near the Canada–United States border. Hydrologically, lakes Lake Michigan–Huron, Michigan and Huron are a single body joined at the Straits of Mackinac. The Great Lakes Waterway enables modern travel and shipping by water among the lakes. The Great Lakes are the largest group of freshwater lakes on Earth by total area and are second-largest by total volume, containing 21% of the world's surface fresh water by volume. The total surface is , and the total volume (measured at the low water datum) is , slightly less than the volume of Lake Baikal (, 22–23% of the world's surface fresh water ...

Sea Lamprey
The sea lamprey (''Petromyzon marinus'') is a parasitic lamprey native to the Northern Hemisphere. It is sometimes referred to as the "vampire fish". Description The sea lamprey has an eel-like body without paired fins. Its mouth is jawless, round and sucker-like, and as wide or wider than the head; sharp teeth are arranged in many concentric circular rows. There are seven branchial or gill-like openings behind the eye. Sea lampreys are olive or brown-yellow on the dorsal and lateral part of the body, with some black marblings, with lighter coloration on the belly. Adults can reach a length of up to and a body weight up to . Etymology The etymology of the genus name ''Petromyzon'' is from '' petro-'' "stone" and '' myzon'' "sucking"; ''marinus'' is Latin for "of the sea". Distribution and habitat The species is found in the northern and western Atlantic Ocean along the shores of Europe and North America, in the western Mediterranean Sea, the Black Sea, and as an invasive speci ...

Pupae
A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence. The pupae of different groups of insects have different names such as ''chrysalis'' for the pupae of butterflies and ''tumbler'' for those of the mosquito family. Pupae may further be enclosed in other structures such as cocoons, nests, or shells. Position in life cycle The pupal stage follows the larval stage and precedes adulthood (''imago'') in insects with complete metamorphosi ...

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

Red Imported Fire Ant
The red imported fire ant (''Solenopsis invicta''), also known as the fire ant or RIFA, is a species of ant native to South America. A member of the genus ''Fire ant, Solenopsis'' in the subfamily Myrmicinae, it was Species description, described by Swiss entomologist Felix Santschi as a variant of ''Solenopsis saevissima, S. saevissima'' in 1916. Its current species, specific name ''invicta'' was given to the ant in 1972 as a separate species. However, the variant and species were the same ant, and the name was preserved due to its wide use. Though South American in origin, the red imported fire ant has been accidentally introduced in Australia, New Zealand, several Asian and Caribbean countries, and the United States. The red imported fire ant is Polymorphism (biology), polymorphic, as workers appear in different shapes and sizes. The ant's colours are red and somewhat yellowish with a brown or black Gaster (insect anatomy), gaster, but males are completely black. Red imported ...

Bar Code
A barcode or bar code is a method of representing data in a visual, Machine-readable data, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode readers, of which there are several types. Later, two-dimensional (2D) variants were developed, using rectangles, dots, hexagons and other patterns, called ''matrix codes'' or ''2D barcodes'', although they do not use bars as such. 2D barcodes can be read using purpose-built 2D optical scanners, which exist in a few different forms. 2D barcodes can also be read by a digital camera connected to a microcomputer running software that takes a photographic image of the barcode and analyzes the image to deconstruct and decode the 2D barcode. A mobile device with an inbuilt camera, such as smartphone, can function as the latter type of 2D barcode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pheromone Trap
A pheromone trap is a type of insect trap that uses pheromones to lure insects. Sex pheromones and aggregating pheromones are the most common types used. A pheromone-impregnated lure, as the red rubber septa in the picture, is encased in a conventional trap such as a bottle trap, Delta trap, water-pan trap, or funnel trap. Pheromone traps are used both to count insect populations by sampling, and to trap pests such as clothes moths to destroy them. Sensitivity Pheromone traps are very sensitive, meaning they attract insects present at very low densities. They are often used to detect presence of exotic pests, or for sampling, monitoring, or to determine the first appearance of a pest in an area. They can be used for legal control, and are used to monitor the success of the Boll Weevil Eradication Program and the spread of the gypsy moth. The high species-specificity of pheromone traps can also be an advantage, and they tend to be inexpensive and easy to implement. This sensitivit ...

Cooperative Extension Service
The Cooperative State Research, Education, and Extension Service (CSREES) was an extension agency within the U.S. Department of Agriculture (USDA), part of the executive branch of the federal government. The 1994 Department Reorganization Act, passed by Congress, created CSREES by combining the former Cooperative State Research Service and the Extension Service into a single agency. In 2009, CSREES was reorganized into the National Institute of Food and Agriculture (NIFA). Mission CSREES' mission is to "advance agriculture, the environment, human health and well-being, and communities" by supporting research, education, and extension programs at land-grant universities and other organizations it partners with. CSREES doesn't conduct its own research; it provides funding and leadership to land-grant universities and competitively granted awards to researchers in partner organizations. CSREES' areas of involvement span across 60 programs in the biological, physical, and social s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
