It is the most widely used herbicide in the world, and the third most commonly used in North America.[1] 2,4-D is also an important synthetic auxin, often used in laboratories for plant research and as a supplement in plant cell culture media such as MS medium. History 2,4-D was developed during World War II by a British team at Rothamsted Experimental Station, under the leadership of Judah Hirsch Quastel, aiming to increase crop yields for a nation at war.[citation needed] When it was commercially released in 1946, it became the first successful selective herbicide and allowed for greatly enhanced weed control in wheat, maize (corn), rice, and similar cereal grass crop, because it only kills dicots, leaving behind monocots. Mechanism of herbicide action 2,4-D is a synthetic auxin, which is a class of plant growth regulators. -
Characterization of Residential Pest Control Products Used in Inner City Communities in New York City

All rights reserved 1559-0631/10 www.nature.com/jes Characterization of residential pest control products used in inner city communities in New York City MEGAN K. HORTONa, J. BRYAN JACOBSONb, WENDY MCKELVEYb, DARRELL HOLMESa, BETTY FINCHERc, AUDREY QUANTANOc, BEINVENDIDA PAEZ DIAZc, FAYE SHABBAZZc, PEGGY SHEPARDc, ANDREW RUNDLEa AND ROBIN M. WHYATTa aColumbia Center for Children’s Environmental Health, Mailman School of Public Health, Columbia University, New York, New York, USA bNew York City Department of Health and Mental Hygiene, New York, New York, USA cWest Harlem Environmental Action, New York, New York, USA The Columbia Center for Children’s Environmental Health (CCCEH) previously reported widespread residential insecticide use in urban communities in New York City. Research suggests that pyrethroids are replacing organophosphates (OPs) in response to 2000–2001 US EPA pesticide regulations restricting OP use. A systematic assessment of active ingredients used for residential pest control is lacking. We queried a database of pesticide applications reported by licensed applicators between 1999 and 2005 and surveyed pest control products available in 145 stores within 29 zip codes in the CCCEH catchment area including Northern Manhattan and the South Bronx. Pyrethroids, pyrethrins, piperonyl butoxide, and hydramethylnon were the most common insecticide active ingredients reported as used by licensed pesticide applicators within the 29 zip codes of the CCCEH catchment area between 1999 and 2005. Use of certain pyrethroids and some non-spray insecticides such as fipronil and boric acid increased significantly by year (logistic regression, OR41.0, Po0.05), whereas use of OPs, including chlorpyrifos and diazinon decreased significantly by year (logistic regression, ORo1.0, Po0.05). -
Carpenter Ants and Control in Homes Page 1 of 6
Carpenter Ants and Control in Homes Page 1 of 6 Carpenter Ants and Control in Homes Fact Sheet No. 31 Revised May 2000 Dr. Jay B Karren, Extension Entomologist Alan H. Roe, Insect Diagnostician Introduction Carpenter ants are members of the insect order Hymenoptera, which includes bees, wasps, sawflies, and other ants. Carpenter ants can be occasional pests in the home and are noted particularly for the damage they can cause when nesting in wood. In Utah they are more of a nuisance rather than a major structural pest. Carpenter ants, along with a number of other ant species, utilize cavities in wood, particularly stumps and logs in decayed condition, as nesting sites. They are most abundant in forests and can be easily found under loose bark of dead trees, stumps, or fallen logs. Homeowners may bring them into their homes when they transport infested logs from forests to use as firewood. Description Carpenter ants include species that are among the largest ants found in the United States. They are social insects with a complex and well-defined caste system. The worker ants are sterile females and may occur in different sizes (majors and minors). Members of the reproductive caste (fertile males and females) are usually winged prior to mating. All ants develop from eggs deposited by a fertilized female (queen). The eggs hatch into grub-like larvae (immatures) which are fed and cared for by the workers. When fully grown, the larvae spin a cocoon and enter the pupal stage. The pupal stage is a period of transformation from the larva to adult. -

Universidade Estadual “Julio de Mesquita Filho” - UNESP. Av. 24 A, 1515, Bela Vista, Rio Claro – SP, Brasil. Abstract Larvae of honeybee workers were exposed to the insecticide fipronil during the feeding phase. To evaluate the effect of fipronil in the post-embryonic development of africanized Apis mellifera, bioassays of toxicity were done. The bioassays were performed by acute exposure applying 1μL of distilled water for control (I) and for experiments: 0.5 ng a.i./µL of fipronil; 5 ng a.i./µL of fipronil and 20 ng a.i./ µL of fipronil. Triplicates were performed for all treatments. The results showed that the rate of anomalous pupae in exposed honeybees was statistically significant in relationship to the control (p <0:03). The most frequent abnormalities were: high pigmentation on the proximal and distal larval body and body malformation, such as absence of head and limbs. -
