Ed(s): R. Newcomb

MeSH headings : Analysis of Variance; Animals; Dose-Response Relationship, Drug; Geography; Linear Models; Male; North America; Oryza / parasitology; Puerto Rico; Sex Attractants / chemistry; Sex Attractants / pharmacology; Sexual Behavior, Animal / drug effects; South America; Species Specificity; Spodoptera / drug effects; Spodoptera / physiology; Zea mays / parasitology
TL;DR: Both strains show rather geographic than strain-specific differences in their response to pheromone lures, and that regional sexual communication differences might cause geographic differentiation between populations. (via Semantic Scholar)

Specificity of the receptor for the major sex pheromone component in Heliothis virescens

Journal of Insect Science (Tucson, AZ), 13.

By: G. Vasquez n, Z. Syed *, P. Estes n, W. Leal * & F. Gould n 

MeSH headings : Animals; Animals, Genetically Modified / genetics; Animals, Genetically Modified / physiology; Arthropod Antennae / physiology; Drosophila melanogaster / genetics; Drosophila melanogaster / physiology; Gene Expression; Insect Proteins / genetics; Insect Proteins / metabolism; Molecular Sequence Data; Moths / genetics; Moths / physiology; Receptors, Odorant / genetics; Receptors, Odorant / metabolism; Sensilla / physiology; Sequence Alignment; Sequence Analysis, DNA; Sex Attractants / metabolism; Sexual Behavior, Animal
TL;DR: Interestingly, a mutation leading to truncation in the HvOR13 C-terminal region affected but did not abolish pheromone receptor response to Z11-16:Ald, and the role of the C- terminal domain in receptor function is discussed. (via Semantic Scholar)

2012 journal article

Fusion Between Southeastern United States Argentine Ant Colonies and Its Effect on Colony Size and Productivity

ANNALS OF THE ENTOMOLOGICAL SOCIETY OF AMERICA, 105(2), 268–274.

By: G. Vasquez n, E. Vargo n & J. Silverman n

author keywords: Linepithema humile; unicoloniality; aggression; colony fusion
TL;DR: Fusion of initially aggressive southeastern United States L. humile colonies results in colonies with higher worker number without decreasing per capita productivity, and offspring contribution by all queens in fused colonies may alter colony genotypic composition resulting in reduced intraspecific aggression that in turn promotes further fusion.

2010 journal article

Differential expression of odorant receptor genes involved in the sexual isolation of two Heliothis moths

INSECT MOLECULAR BIOLOGY, 20(1), 115–124.

By: G. Vasquez n, P. Fischer n, C. Grozinger* & F. Gould n 

author keywords: odorant receptors; pheromone; gene expression; Heliothis virescens; Heliothis subflexa
MeSH headings : Animals; Arthropod Antennae / metabolism; Female; Gene Expression Regulation; Genes, Insect; Hybridization, Genetic; Male; Moths / genetics; Moths / metabolism; Olfactory Perception; Polymerase Chain Reaction; Receptors, Odorant / genetics; Receptors, Odorant / metabolism; Sex Attractants / genetics; Sex Attractants / metabolism; Sex Factors; Sexual Behavior, Animal; Species Specificity
TL;DR: Quantitative real‐time PCR analysis indicates that expression of HvOR 6, HsOR6, Hv OR14, H vOR14, hvOR15 and Hs OR15 is male biased, which supports the hypothesis that they have a role in mediating female sex pheromone detection. (via Semantic Scholar)

2009 journal article

Colony Fusion in Argentine Ants is Guided by Worker and Queen Cuticular Hydrocarbon Profile Similarity

JOURNAL OF CHEMICAL ECOLOGY, 35(8), 922–932.

By: G. Vasquez n, C. Schal n  & J. Silverman n

Contributors: G. Vasquez n, C. Schal n  & J. Silverman n

author keywords: Argentine ant; Linepithema humile; Nestmate recognition; Cuticular hydrocarbons; Intraspecific aggression; Colony fusion; Supercoloniality
MeSH headings : Aggression; Animals; Ants / genetics; Ants / physiology; Behavior, Animal; Discriminant Analysis; Genetic Variation; Hydrocarbons / chemistry; Social Behavior
TL;DR: Changes in worker and queen chemical profiles in fused colonies suggest that CHC plasticity may sustain the cohesion of unrelated L. humile colonies that had fused, and demonstrate that colony fusion correlates with both genetic and CHC similarities. (via Semantic Scholar)

2008 journal article

Cuticular hydrocarbons as queen adoption cues in the invasive Argentine ant

JOURNAL OF EXPERIMENTAL BIOLOGY, 211(8), 1249–1256.

By: G. Vasquez n, C. Schal n  & J. Silverman n

Contributors: G. Vasquez n, C. Schal n  & J. Silverman n

author keywords: Argentine ant; Linepithema humile; nestmate recognition; cuticular hydrocarbons; intraspecific aggression; non-nestmate queen adoption
MeSH headings : Aggression; Animals; Ants / physiology; Biological Assay; Cues; Discriminant Analysis; Female; Hydrocarbons / metabolism; Integumentary System; Male; Social Behavior
TL;DR: An association between non-nestmate queen adoption and similarity of the CHC profiles of adopted and host colony queens is found, which provides further evidence for the complex and dynamic nature of L. humile nestmate discrimination, which may in part underlie the success of introduced populations of this invasive ant.

Intraspecific aggression and colony fusion in the Argentine ant

ANIMAL BEHAVIOUR, 75, 583–593.

By: G. Vasquez n & J. Silverman n

author keywords: aggression; Argentine ant; colony fusion; cuticular hydrocarbons; genetic similarity; invasive species; Linepithema humile (Mayr); nestmate recognition; unicoloniality
TL;DR: It is suggested that selective fusion of initially aggressive colonies sharing certain recognition cues may be a proximate mechanism shaping L. humile social structure, leading ultimately to extreme unicoloniality in introduced populations when ecological conditions are favourable.

2007 journal article

Queen acceptance and the complexity of nestmate discrimination in the Argentine ant

BEHAVIORAL ECOLOGY AND SOCIOBIOLOGY, 62(4), 537–548.

By: G. Vasquez n & J. Silverman n

author keywords: Argentine ant; Linepithema humile; nestmate recognition; aggression; genetic similarity; non-nestmate adoption
TL;DR: A role for genetically based cues in L. humile colony queen number is indicated and an effect of resident queens on worker conspecific acceptance thresholds is suggested, suggesting subtle discrimination capability seems to be influenced by the social context, as demonstrated by more frequent recognition errors in queenless colonies.

TL;DR: Esthetic damage parameters, including exuviae, honeydew, and sooty mold on leaves, were significantly different between treatments and untreated control, and damage levels were minimal with the insecticide treatment and natural enemy releases. (via Semantic Scholar)
