2003 journal article

Nestmate discrimination in ants: effect of bioassay on aggressive behavior

INSECTES SOCIAUX, 50(2), 151–159.

By: T. Roulston n, G. Buczkowski n & J. Silverman n

author keywords: aggression assay; Formicidae; nestmate recognition; Argentine ants; Linepithema humile
TL;DR: All live ant assays tested are useful tools for analyzing aggressive interactions between colonies, but that the pairing of a live and dead ant produced inconsistent results and generally lower levels of aggression. (via Semantic Scholar)

2003 journal article

Retrieval of granular bait by the Argentine ant (Hymenoptera : Formicidae): Effect of clumped versus scattered dispersion patterns

JOURNAL OF ECONOMIC ENTOMOLOGY, 96(3), 871–874.

By: J. Silverman n & T. Roulston n

author keywords: Linepithema humile; Argentine ant; foraging; granular bait
TL;DR: These results suggest that Argentine ant colonies adjust their foraging patterns to resources of different quality (prey versus bait) and are consistent with prior field results demonstrating no efficacy advantages to discrete granular bait placements. (via Semantic Scholar)

2002 journal article

The effect of food size and dispersion pattern on retrieval rate by the Argentine ant, Linepithema humile (Hymenoptera : formicidae)

JOURNAL OF INSECT BEHAVIOR, 15(5), 633–648.

By: T. Roulston n & J. Silverman n

author keywords: foraging; Formicidae; Linepithema; food retrieval; Argentine ant
TL;DR: The results generally support theoretical foraging models, but it is shown how prey size, through differential prey-handling behavior, can produce an outcome greatly different from that predicted only on the distribution of resources. (via Semantic Scholar)

2001 journal article

Acceptance and intake of gel and liquid sucrose compositions by the argentine ant (Hymenoptera : Formicidae)

JOURNAL OF ECONOMIC ENTOMOLOGY, 94(2), 511–515.

By: J. Silverman n & T. Roulston n

author keywords: Linepithema humile; Argentine ant; ants; bait; liquid gel
MeSH headings : Animals; Ants; Argentina; Carbohydrates; Feeding Behavior; Gels; Insect Control / methods; Time Factors
TL;DR: Comparing the feeding responses of the Argentine ant to liquid and gel compositions of sucrose suggests that liquid formulations may provide more effective control of Argentine ants due to the greater speed and abundance in which it is ingested. (via Semantic Scholar)

2000 review

Pollen nutritional content and digestibility for animals

[Review of ]. PLANT SYSTEMATICS AND EVOLUTION, 222(1-4), 187–209.

By: T. Roulston n & J. Cane *

author keywords: pollen chemistry; pollen digestion; pollination syndrome; palynology; bees; nutrition
TL;DR: Study on the mechanism(s) of pollen digestion remain inconclusive, but suggest that differences in digestibility among pollen types may reflect differences in pollen wall porosity, thickness, and composition. (via Semantic Scholar)
