Abstract Thrips hawaiiensis is a common thrips pest that damages the flowers of various plants. The differing population sizes T. among host plants suggest its preference and performance vary In this study, fitness for different was assessed through field investigation. behavioral responses to color volatiles eliciting apparent levels their development survival on were also studied. Adults larv...

The purpose of this study is to test the feasibility of applying an interpretive structural modeling (ISM) method for case hosts to develop verity design solution of case host preference-based products. In the early design concept stage of the product development, designers often need to create many ideas as the case of products for the main idea of what case the host wants. Hence, a conversion...

Under the preference-performance hypothesis, natural selection will favor females that choose oviposition sites that optimize the fitness of their offspring. Such a preference-performance relationship may entail important consequences mainly on fitness-related traits. We used the well-characterized cactus-Drosophila system to investigate the reproductive capacity in the pair of sibling species ...

Animals often express behavioral preferences for different types of food or other resources, and these preferences can evolve or shift following association with novel food types. Shifts in preference can involve at least two phenomena: a change in rank preference or a change in specificity. The former corresponds to a change in the order in which hosts are preferred, while a shift in specifici...

Factors constraining host specificity are poorly understood. Intraspecific variation in host preferences in generalist parasites may reveal which factors affect patterns of host use, and thus the evolution of specialization. Here, laboratory experiments examined genetic variation in host preferences and the effect of a refugium against infection on host use. Firstly, 6 cercarial clones of the t...

The preference-performance hypothesis predicts that female insects maximize their fitness by utilizing host plants which are associated with high larval performance. Still, studies with several insect species have failed to find a positive correlation between oviposition preference and larval performance. In the present study, we experimentally investigated the relationship between oviposition ...
