The sterile insect technique (SIT) [1] [2] is a method of biological insect control, whereby overwhelming numbers of sterile insects are released into the wild. The released insects are preferably male , as this is more cost-effective and the females may in some situations cause damage by laying eggs in the crop, or, in the case of mosquitoes ...
The F1 sterile progeny produced in the field enhance the efficacy of released partially sterile males, and improve compatibility with other pest control strategies. For example, the presence of F1 sterile progeny can be used to increase the build-up of natural enemies in the field.
These animals are usually sterile due to the different numbers of chromosomes between the two parents. The imbalance results in offspring that is viable but not fertile, as is the case with the mule. Sterility can also be caused by selective breeding, where a selected trait is closely linked to genes involved in sex determination or fertility.
Microorganisms growing on an agar plate. Sterilization (British English: sterilisation) refers to any process that removes, kills, or deactivates all forms of life (particularly microorganisms such as fungi, bacteria, spores, and unicellular eukaryotic organisms) and other biological agents (such as prions or viruses) present in fluid or on a specific surface or object.

Equipment used in aseptic processing of food and beverages must be sterilized before processing and remain sterile during processing. [1] When designing aseptic processing equipment there are six basic requirements to consider: the equipment must have the capability of being cleaned thoroughly, it must be able to be sterilized with steam, chemicals, or high-temperature water, sterilization ...
SIT technique may be applied as part of an area-wide control (integrated pest management) approach of insects of medical, veterinary, and agricultural importance. It was in 1937 when Edward Knipling proposed using sterilization to control or eradicate insect pests after observation that screwworm fly males mate repeatedly while females mate ...
Acupuncture is generally safe when administered by an experienced, appropriately trained practitioner using clean-needle technique and sterile single-use needles. [18] When improperly delivered it can cause adverse effects. [17] Accidents and infections are associated with infractions of sterile technique or neglect on the part of the ...
While all members of the surgical team should demonstrate good aseptic technique, it is the role of the scrub nurse or surgical technologist to set up and maintain the sterile field. [ 13 ] [ 14 ] To prevent cross-contamination of patients, instruments are sterilized through autoclaving or by using disposable equipment; suture material or ...
