The oldest Western Hemisphere recorddates from 1985. This species has gone unrecognizedprobably because of its close resemblanceto species of the New World genus TrichopeplaSt'al. The primary host plant of A. puberula is the introducedweed, com- mon horehound,Marrubium vulgare L. It has also been reported damaging winter fruits in South Africa. Key Words:cluster bug, horehound,stink bug, invasive species RESUMEN Una especie Africana de Pentatomini,Agonoscelis puberula St'al,es reportada por primera vez para M6xico,sur de Estados Unidos y las islas de Jamaica y Espaniola,en donde se ha establecido.

  • A Comparison Between European and Australian Populations of Horehound, (Marrubium Vulgare L.)
    Twelfth Australian Weeds Conference A COMPARISON BETWEEN EUROPEAN AND AUSTRALIAN POPULATIONS OF HOREHOUND, (MARRUBIUM VULGARE L.) John Weiss1, Jean-Louis Sagliocco2 and Emma Wills1 1 Keith Turnbull Research Institute, Victorian Department of Natural Resources and Environment, Cooperative Research Centre for Weed Management Systems, PO Box 48, Frankston, Vic. 3199 2 CSIRO Biological Control Unit, Cooperative Research Centre for Weeds Management Systems, 34980 Montferrier-sur-Lez, France Abstract Horehound (Marrubium vulgare L.: Lamiaceae), a noxious weed throughout southern Aus- tralia, was imported from its native southern Europe during the 1800s. Horehound in its native habitats shows weed potential, but plant populations are scat- tered and their density is lower than Australian infes- tations where the plants are larger and more vigorous. Climate modelling based on overseas populations in- dicate that horehound in Australia maybe close to achieving its maximum potential distribution. The seed production and seed bank studies indicate that there is at least a one hundred fold difference between the populations on the two continents. At Victorian infes- tations, either competition or water appear to be the limiting factors affecting survival and recruitment while sustained herbivory pressure restricts Horehound in its Figure 1. Distribution of horehound in Europe (adapted native range. from Anerberg et al., 1996) The insect fauna of horehound in Europe has been examined and four insects have been identified as suit- able agents for biological control. Two of these have been approved for release into Australia. INTRODUCTION Horehound is a perennial weed native to temperate Eurasia, Europe, the Middle East and the Mediterra- nean region including North Africa (Figure 1).

  • On Sexual Selection in Florida's Pyractomena
    114 Florida Entomologist 86(2) June 2003 ON SEXUAL SELECTION IN FLORIDA’S PYRACTOMENA BOREALIS (COLEOPTERA: LAMPYRIDAE) ERIN GENTRY Department of Entomology and Nematology, University of Florida, Gainesville, Florida 32611 ABSTRACT To what extent can a small animal with limited mobility use behavior to take advantage of its environment and how might this influence the population as a whole? This was examined in a firefly species Pyractomena borealis (Randall), by looking at the features of the micro- habitat where larvae pupate, how developmental rates are influenced by extrinsic factors, and how the population’s spatial distribution differed according to sex. In two populations of P. borealis in Gainesville Florida, larvae pupated at the warmest locations on trees, poten- tially causing a faster development rate than individuals in cooler areas. In these popula- tions males pupated sooner and in warmer areas than females, suggesting males chose their pupation locations in order to have a shorter development period and an earlier emergence date than females. This is the first evidence of protandry being experimentally linked with behavioral usage of habitat. Key words: protandry, Microhabitat, Microclimate, Pupation Duration, Ectotherm, Behavior RESUMEN Hasta que punto puede un animal pequeño con mobilidad limitada usar el comportamiento para aprovecharse de su ambiente y como esto puede influenciar la población completa? Esto fué investigado en una especie de luciérnaga Pyractomena borealis (Randall), al observar las características del microhabitat donde se empupan las larvas, como las tasas de desarrollo son influenciadas por factores extrínsicos, y como la distribución espacial de la población va- ria de acuerdo al sexo.
