Organophosphate and carbamate insecticides are the most common type of insecticide used on crops and in the home. Most pesticide poisonings result from exposure to organophosphate insecticides. Organophosphate and carbamate insecticides affect the nervous system of people. Exposure to toxic amounts can cause adverse effects ranging from shortness of breath, excessive salivation, nausea, vomiting, headache, dizziness and chest discomfort to convulsions, paralysis and even death.

Mosquito control for West Nile virus includes adulticide and larvicides. Larvicides include biological insecticides, such as Bacillus sp, temephos, and methoprene. Although the exact pesticide and concentration used will vary regionally, approved mosquito control pesticides are generally applied at very low concentrations. It is unlikely that adverse health effects will occur as a result of this type of use, but some animals may experience adverse effects. See similar questions...

Mother-to-mother support groups utilize a methodology that follows an organized, yet flexible format with guided discussion, rather than a formal class where "experts" teach. Each meeting has a different topic for discussion. The facilitator briefly introduces the topic and then encourage others to share their experiences and thoughts. See similar questions...

Based on the standard of 996 points fitting into 35 centimeters, and 2.54 centimeters per inch, we have 72 points equal to 0.9961104 inch. Taking a number of commonly used values (including fractional points for calculating the true sizes of 3-in-em, 4-in-em, and 5-in-em spacing) we can produce the following table: See similar questions...

Features of the zebrafish strongly favor studying embryology and collecting and analyzing mutations and comparing them to other vertebrates. There are invertebrates that are equally or better suited for these types of studies, but they have very different anatomy patterns of development. These and other approaches allow a problem to be studied from many different experimental points of view, resulting in a better understanding of it. See similar questions...

Since its inception, the Environmental Protection Agency (EPA) has regulated mosquito control through enforcement of standards instituted by the Federal Insecticide, Fungicide, and Rodenticide Act. This legislation mandated documentation of extensive testing for public health insecticides according to EPA guidelines prior to their registration and use. See similar questions...
