Cucumber Beetle
Cucumber beetle is a common name given to members of two genera of beetles, ''Diabrotica'' and '' Acalymma'', both in the family Chrysomelidae. The adults can be found on cucurbits such as cucumbers and a variety of other plants. Many are notorious pests of agricultural crops. The larvae of several cucumber beetles are known as corn rootworms. Some well-known pests include the western corn rootworm (''D. virgifera virgifera''), the spotted cucumber beetle and its larva, the southern corn rootworm (''D. undecimpunctata''), the cucurbit beetle (''D. speciosa''), the banded cucumber beetle (''D. balteata''), the northern corn rootworm (''D. barberi''), the striped cucumber beetle (''A. vittatum''), and the western striped cucumber beetle (''A. trivittatum''). The insects live about eight weeks, during which time both larva and adult feed on plants. Adults will attack the tender young growth of stems and leaves, and the buds and petals on mature specimens. They also carry and s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spotted Cucumber Beetle
''Diabrotica undecimpunctata'', the spotted cucumber beetle or southern corn rootworm, is a species of cucumber beetle that is native to North America. The species can be a major agricultural pest insect in North America. Spotted cucumber beetles cause damage to crops in the larval and adult stages of their life cycle. Larvae feed on the roots of the emerging plants, which causes the most damage since the young plants are more vulnerable. In the adult stage the beetles cause damage by eating the flowers, leaves, stems, and fruits of the plant The beetles can also spread diseases such as bacterial wilt and mosaic virus. Description The spotted cucumber beetle has three subspecies, each with a different common name: *''Diabrotica undecimpunctata howardi'' – spotted cucumber beetle or southern corn rootworm *''Diabrotica undecimpunctata tenella'' – western cucumber beetle *''Diabrotica undecimpunctata undecimpunctata'' – western spotted cucumber beetle In the adult form, ...

''Diabrotica speciosa'', also known as the cucurbit beetle and in Spanish as ''vaquita de San Antonio'' (this common name is also given to many ladybugs) is an insect pest native to South America. Its larvae feed on the roots of crops. The cucurbit beetle (''Diabrotica speciosa'') is also known to transmit several viruses such as comoviruses and different mosaic viruses. ''Diabrotica speciosa'' (''D. speciosa'') is native to South America and is now distributed in Central America and other global areas. Common names include the Cucurbit Beetle and San Antonio beetle. Their native land is South America in countries such as Argentina, Bolivia, Brazil, Colombia, Ecuador, French Guiana, Paraguay, Peru, Uruguay and Venezuela. Their current distribution is in Central America including countries such as Costa Rica, Mexico, and Panama.

Bacterial Wilt
Bacterial wilt is a complex of diseases that occur in plants such as Cucurbitaceae and Solanaceae (tomato, common bean, etc.) and are caused by the pathogens ''Erwinia tracheiphila'', a gram-negative bacterium, or ''Curtobacterium flaccumfaciens pv. flaccumfaciens'', a gram-positive bacterium. Cucumber and muskmelon plants are most susceptible, but squash, pumpkins, and gourds may also become infected. Bacterial wilts of tomato, ''Capsicum'' (pepper), '' Solanum ovigerum'' (eggplant), and Irish potato can be caused by (Burkholderiaceae) ''Ralstonia solanacearum''. Other bacteria in the family Burkholderiaceae can cause bacterial wilt of carnation. Bacteria in the genus '' Xanthomonas'' can cause banana bacterial wilt or bacterial wilt in the genus ''Agrostis''. Disease transmission ''Erwinia tracheiphila'' is spread between plants by two species of insect vectors, striped cucumber beetles (''Acalymma vittatum'') and spotted cucumber beetles (''Diabrotica undecimpunctata''). ...

Malathion
Malathion is an organophosphate insecticide which acts as an acetylcholinesterase inhibitor. In the USSR, it was known as carbophos, in New Zealand and Australia as maldison and in South Africa as mercaptothion. Pesticide use Malathion is a pesticide that is widely used in agriculture, residential landscaping, public recreation areas, and in public health pest control programs such as mosquito eradication. In the US, it is the most commonly used organophosphate insecticide. A malathion mixture with corn syrup was used in the 1980s in Australia and California to combat the Mediterranean fruit fly. In Canada and the US starting in the early 2000s, malathion was sprayed in many cities to combat west Nile virus. Malathion was used over the last couple of decades on a regular basis during summer months to kill mosquitoes, but homeowners were allowed to exempt their properties if they chose.. Mechanism of action Malathion is an acetylcholinesterase inhibitor, a diverse family of c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyfluthrin
Cyfluthrin is a pyrethroid insecticide and common household pesticide. It is a complex organic compound and the commercial product is sold as a mixture of isomers. Like most pyrethroids (MoA 3a), it is highly toxic to fish and invertebrates, but it is far less toxic to humans. It is generally supplied as a 10–25% liquid concentrate for commercial use and is diluted prior to spraying onto agricultural crops and outbuildings. Safety In rats, the s are 500, 800 (oral), and 600 (skin) mg/kg. Excessive exposure can cause nausea, headache, muscle weakness, salivation, shortness of breath and seizures. In humans, it is deactivated by enzymatic hydrolysis to several carboxylic acid metabolites, whose urinary excretion half-lives are in a range of 5–7 hours. Worker exposure to the chemical can be monitored by measurement of the urinary metabolites, while severe overdosage may be confirmed by quantification of cyfluthrin in blood or plasma. Health and safety risks are controlled by ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrethrin
The pyrethrins are a class of organic compounds normally derived from ''Chrysanthemum cinerariifolium'' that have potent insecticidal activity by targeting the nervous systems of insects. Pyrethrin naturally occurs in chrysanthemum flowers and is often considered an organic insecticide when it is not combined with piperonyl butoxide or other synthetic adjuvants.Mader, Eric, and Nancy Lee Adamson. "Organic-Approved Pesticides."Organic-Approved Pesticides (n.d.): n. pag. The Xerxes Society. The Xerces Society for Invertebrate Conservation, Oct. 2012. Web. 10 Mar. 2015. Their insecticidal and insect-repellent properties have been known and used for thousands of years. Pyrethrins are gradually replacing organophosphates and organochlorides as the pesticides of choice as the latter compounds have been shown to have significant and persistent toxic effects to humans.They first appeared on markets in the 1900's and have been continually used since then in products such as bug bombs, bui ...
