organism gives virus to children through birth
native to Asia,
origin
We use a genetic algorithm, Genetic Algorithm for Rule SetProduction (GARP), to determine the ecological niche of Ae. albopictus and predict a globalecological risk map for the continued spread of the species.
method: using genetic algorthms to predict where specifically the ATM can spread
is likely to spread increasingly northward and through Western Europe as climate change expands the Asian tiger mosquito's habitat.
important intersectionalisty with climate change
Dengue fever,
some UN facts: Dengue is a viral infection caused by the dengue virus (DENV), which is transmitted to humans through the bite of infected mosquitoes. About half of the world's population is now at risk of dengue, with an estimated 100–400 million infections occurring each year. Dengue is found in tropical and sub-tropical climates worldwide, mostly in urban and semi-urban areas. While many DENV infections are asymptomatic or produce only mild illness, DENV can occasionally cause more severe cases, and even death. Prevention and control of dengue rely on vector control. There is no specific treatment for dengue/severe dengue, and early detection and access to proper medical care greatly lower fatality rates of severe dengue.
We recommend those collaborations begin in the northern US range
start where diapuase is greatest
a loss in the expression of diapause as the species spread into sub-tropical Florida.
delaying egg development not as nevessary bc they will survuve just fine
Moderate immigration into range-edge locations should boost genetic diversit
evoluition -> genetic diversity
Estimate SE Z-value p
???
Diapause incidence was significantly lower in range-core versus range-edge populations (coefficient = 0.72; p < .001),
bc they didnt need to adjust?

instar larvae
developmental stage of arthropods, such as insects
To establish subsequent generations, we hatched eggs by submersing egg papers in a solution of 0.35g/L DifocoTM Nutrient Broth (Becton, Dickinson and Company) in deionized water and provided hatched larvae with ad libitum access to bovine liver powder (MP Biomedicals) as a food source. We provided adults a 20% sucrose solution and allowed them to bloodfeed twice daily on defibrinated bovine blood (Hemotek Laboratories) secured inside hog casing, warmed in a 70°C water bath and placed on the top of the mesh top of the colony cage for feeding.
how they were fed during experiment
oviposition
organ insects use to lay eggs
50 field-collected individuals of each sex,
sample size
2.1 Sample collection and lab colonies
method
By exposing diapause-induced eggs from both regions to range-core and range-edge winters, we were able to evaluate whether this species is broadly adapted to winter or if northern populations are adapted to northern winters.
method
range edge
critical areas to research
resident genotypes should have higher relative fitness than immigrant genotypes, thus limiting the establishment of immigrant genotypes and potentially hindering continued immigration into locally adapted demes
measures that combat against invasiveness
invasion biology and disease ecology
key idea for asian tiger mosquito bc its an invasive disease carrier
(~3 decades)
takes species 30b years to adequately adjust
cline
cline is a measurable gradient in a single characteristic of a species across its geographical range
diapause
Diapause is the delay in development in response to regular and recurring periods of adverse environmental conditions.
Photoperiodically
physiological reaction of organisms to the length of light or a dark period. It occurs in plants and animals.
