Document Summary
Selfish elements: 2 types, homing endonuclease genes (hegs, transposable genes (tes, selfish genes can change frequency of genes more rapidly than by selection, used in vector elimination. Underdominance: a genetic engineering tactic to reduce hybrid fitness, 2 traits combine for lower fitness than either trait by itself. Pmi: post-mortem interval, time between death and discovery, very important in crimes, helps establish alibi, where to look for other eyewitnesses. Location of death: use insects to calculate, need to assume: Insect growth is linear (degree days: food is not limiting, average temp of each day is good enough to calculate the dd"s. Intoxicating the larvae: can use toxins/oils to suffocate it. It is a type of biocontrol: hits before the bite, used in eliminating vectors. Adulticiding: kills adults, cons, accidentally kills good bugs, toxic, resistance over the years, expensive because you need a lot of coverage, pros, effective for ectoparasites. Vectorial capacity: taken into consideration for eliminating vectors.
