Influence of egg size on egg and larval development of Sympetrum striolatum at different prey availability (Odonata: Libellulidae)

摘要: Abstract Egg size differences might have an important influence on reproductive success because they may lead to different offspring conditions, hatching date or larval size. We presumed that egg in odonates positively correlates with development time, and larger eggs larvae. However, we assumed the benefit could only be maintained under harsh, but not good conditions. Harsh conditions were simulated by diets specific feeding intervals; high prey level fed every day, low second day. The organisms used Artemia salina Chironomus riparius. study was conducted libellulid Sympetrum striolatum. Our results showed caused a longer time. Larger resulted significantly first instar larvae their C. found no significant between with...
