Eradication of invasive species: why the biology matters.

In order to positively evaluate the geographical distribution and relative abundance (measured invasiveness) of the six invasive herbivorous insect species in the United States and Mexico, to the published physiology and nutrition including similar subelements Based ecosystem model was used. The plant host and insect species included in this study were 1) cotton / pink cotton borg, 2) fruit / host fruit fly, 3) olive / olive fried, 4) perennial / light brown apple moth, 5) grape /Met. Glass wing sharp shooter and its two egg parasitoid wasps, and 6) grape / grape vines in Europe. All of these species are currently targeted or eradicated. The purpose of the analysis is to predict and predict the different distributions of the six species as the basis for investigating efforts to eradicate them or contain containment efforts. Because of its central role in the development of the eradication paradigm, the discussion section also examined the eradication of the new world of spiral worms. The model used is a dynamic description of biology by that kind of weather. We used daily weather data (ie maximum and minimum temperatures, solar radiation) from 1,221 locations in the US and Mexico between 1983 and 2003 to drive the model. Soil moisture and nutrients are considered to be non-limiting. Draw simulation results using GRASS GIS. The mathematical basis of the modeling method is outlined in the appendix and supplemental material.

As the scope of the study is wide, a brief review of the biology, invasion history, and eradication or containment efforts of each of the six invasive species, as a background for assessing their expected geographical distribution and abundance It helps. These species were discussed in order of invasion into California. Edible pink weevils are Indian tropical species or are more likely to be the origin of the northern Australian Papua New Guinea (see van den Bosch and Messenger 1973, Grefenstette et al. It is widely distributed in cotton growing areas around the world, where other types of Malvaceae (such as okra and aoi) are also attacking. Pink Watami earthworm was first discovered in Florida cotton trees in 1932 and spread to commercial and cotton in the US and Mexico. In the late 1960s, Ali invaded the desert cotton area of ​​Arizona and Southern California and became the main pest.

Invasive species studies can be done in many sub-disciplines of biology, but most research on invading organisms belongs to the field of ecology and geography, the issue of biological invasion is particularly important. Most of the studies on invasive species are influenced by Charles Elton's 1958 book "Animal and Plant Entry Ecology". . Invasive species studies have been rare until the 1990s, and research in that field has experienced significant growth and has reached today. This research consists mainly of field observation studies and is disproportionately related to terrestrial plants. Rapid development in this area has driven the need for language standardization to describe invasive species and events.
