Document Summary
Sterile mosquitoes: figure 2: the timeline of when we start to see larvae in the field. This is the demonstration that the riddle has worked to some extent. In an isolated island in the cayman islands. Wolbachia: releases every week for 9-10 weeks (between 10-20,000/wk). The wolbachia frequency goes up to 100% or near it, even after mosquitoes have stopped being released. In two isolated towns in northern australia released every week. Chemical communication in pieris butterflies: males court virgin females much more vigorously. If every mating results in parasitism, there would be very strong selection to change that signal. Over space and time, the males that can court fresh females have higher fitness. Monarch migration: benefits must outweigh costs otherwise we wouldn"t see the strategy persisting. So many plants being set out for monarchs (intentionally conservation or not gardens), we are seeing less monarch migration.
