Effect of diet and density on larval immune response and larval and adult host-preference in Spodoptera littoralis

Sophie Chattington Epsilon Archive for Student Projects (University of Southampton) 2015

Other claims from this paper (7)

Observation Low density rearing was optimal for pupal weight and egg load.
Observation High density larvae invested more in immune response.
Observation High density reduced pupal weight and egg load.
Observation Starvation increased development time and death rate.
Observation Larvae made experience based host choices regardless of density.
Observation Adult oviposition choice shifted from a choice pattern after low density rearing to apparently random laying after high density rearing.
Observation Adults reared at high density first laid eggs on a plant they had not experienced.

Other claims from this paper (6)

Intervention effect Released parasitoids parasitized an estimated 57.4% of placed corn borer egg masses.

Intervention effect Parasitoid releases reduced tunnels per corn stalk by 92.9%.
Intervention effect Parasitoid releases reduced corn borer larvae per stalk by 94.3%.
Intervention effect Ear damage was suppressed to acceptable cut-corn processing standards.
Mechanism Density-dependent larval loss would not compensate for egg parasitism by T. nubilale.
