Plant diversity is known to affect success of host location by pest insects, but its effect on olfactory orientation of non-pest insect species has hardly been addressed. First, we tested in laboratory experiments the hypothesis that non-host plants, which increase odour complexity in habitats, affect the host location ability of herbivores and parasitoids. Furthermore, we recorded field data o...

Basal and plasticity of thermal tolerance determine abundance, biogeographical patterns and activity of insects over spatial and temporal scales. For coexisting stemborer parasitoids, offering synergistic impact for biological control, mismatches in thermal tolerance may influence their ultimate impact in biocontrol programs under climate variability. Using laboratory-reared congeneric parasito...

Discrete-time models are the traditional approach for capturing population dynamics of a hostparasitoid system. Recent work has introduced a semi-discrete framework for obtaining model update functions that connect host-parasitoid population levels from year-to-year. In particular, this framework uses differential equations to describe the hosts-parasitoid interaction during the time of year wh...

A fragmented habitat becomes increasingly fragmented for species at higher trophic levels, such as parasitoids. To persist, these species are expected to possess life-history traits, such as high dispersal, that facilitate their ability to use resources that become scarce in fragmented landscapes. If a specialized parasitoid disperses widely to take advantage of a sparse host, then the parasito...

A case is presented of a 15-year-old boy with a past medical history of hyperlipidemia and hypertension. He attended the emergency department with a 3-day history of vomiting, acute abdominal pain, and altered mental status. Laboratory data on admission revealed metabolic acidosis (pH: 7.12, BE: -20.8 mmol/L), high blood glucose level (32.1 mmol/L) and significant hyperlipidemia (cholesterol: 1...

Vision of the Crowds is a paraphrase of the well-known notion Wisdom of the Crowds. In the latter, instead of using an ontology-based, top-down approach, we create knowledge rather bottom-up, relying on the knowledge of the members of a certain community. Well-known applications of this approach are cooperative tagging of photos or filtering spams. In the case of Vision of the Crowds, we do not...
