Larval dispersal refers to the spread of larvae from a spawning source to a settlement site. Larval dispersal is an important process during the life cycle of blow flies when the larvae leave their food substrate and search for a suitable place to pupariate. The larvae may be at risk of predation, parasitization and desiccation during this stage. The substrates in which immature stages of blow flies develop are discrete and ephemeral and are normally saturated with insects of one or more species. The larvae attempt to feed as much as possible before the complete exhaustion of resources and start searching for a pupariation site or for another source of food, if they are not mature enough for pupariation. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
