RESUMO
Achatina fulica Bowdich, 1822 is an african snail that is invasive in different parts of the world, being characterized mainly by its high adaptability. Our objective was to evaluate the influence of abiotic factors, such as temperature and substrate, on the egg eclosion, adult and juvenile reaction to different abiotics factors, and the resistance of A. fulica to popular methods of control. Three studies were made, including 19 laboratory experiments and observations of free animals in the municipal district of Guaraqueçaba, southern Brazil. Eggs were characterized as the most fragile phase, whereas the juveniles and adults were resistant to the immersion in fresh and salt water and little resistant to temperature variation and salt, using burying, aestivation, and muscular force as defense strategies. Those strategies should be considered in management actions and in orientating popular methods of control.
