摘要: We report behavioral alterations induced by tapeworm (Hymenolepis diminuta) infection in several genetic strains of two species flour beetles, Tribolium, under levels a laboratory environment. Under high level infection, Tribolium castaneum (strain cSM) shows decreased emigration and surface-seeking behavior increased cannibalism. In contrast confusum b+) behavior, cannibalism is not significantly changed. low affected any the 11 examined. Prevalence parasitism positively associated with rate. Different T. exhibited different susceptibility to suggesting intraspecific variation infection. This basis may reflect past differences selection resulting from histories suggests could evolve as a...
