The intact or treated larvae were completely dried over 3 days after incubation in water for 1 day. They were judged as surviving when they could move their body after rehydration.
Values are means±S.D.
The larvae that turned black (having presumably died before complete dehydration) were eliminated from the data.
The different letters indicate a significant difference between values(Mann—Whitney U test; P<0.05).
