- The pesticide DDT was widely used in the 1940s as a method of insect control. In the late 1950s the first DDT-resistant mosquitoes were discovered, and eventually DDT-resistant mosquitoes were found globally.

After the eggs had hatched, tadpoles were raised in artificially constructed 2 L containers in a laboratory. All containers were filled with 1 L of filtered tap water, and the water was changed every other day. Thirteen tadpoles were placed in each container, and the tadpoles were exposed to a 12-hour light: 12-hour dark photoperiod. All tadpoles were fed thawed spinach daily. The researchers randomly placed the tadpoles into containers exposed to one of four treatments, with nine replicates of each treatment, as follows: Low UVBR (<6.0 kJ/m2), low temperature (15OC) Low UVBR (<6.0 kJ/m2), high temperature (26OC) High UVBR (>70.0 kJ/m2), low temperature (15OC) High UVBR (>70.0 kJ/m2), high temperature (26OC) The researchers recorded the number of tadpoles still alive out of the original 13 in a container (percent survival) at different time periods.
