Precipitation And Temperature Effects On Populations Of Aedes Albopictus (Diptera : Culicidae): Implications For Range Expansion, B W. Alto, Steven A. Juliano
Precipitation And Temperature Effects On Populations Of Aedes Albopictus (Diptera : Culicidae): Implications For Range Expansion, B W. Alto, Steven A. Juliano
Faculty Publications – Biological Sciences
We investigated how temperature and precipitation regime encountered over the life cycle of Aedes albopictus (Skuse) affects populations. Caged populations of A. albopictus were maintained at 22, 26, and 30 degreesC. Cages were equipped with containers that served as sites for oviposition and larval development. All cages were assigned to one of three simulated precipitation regimes: (1) low fluctuation regime - water within the containers was allowed to evaporate to 90% of its maximum before being refilled, (2) high fluctuation regime - water was allowed to evaporate to 25% of its maximum before being refilled, and (3) drying regime - …

Temperature Effects On The Dynamics Of Aedes Albopictus (Diptera : Culicidae) Populations In The Laboratory, Barry W. Alto, Steven A. Juliano
Faculty Publications – Biological Sciences
We investigated how constant temperatures of 22, 24, and 26 degreesC experienced across the full life cycle affected the dynamics of caged populations of Aedes albopictus (Skuse). All cages were equipped with plastic beakers that served as sites for oviposition and larval development. We measured the per capita daily mortality and emergence rates of the adults and size of adult females, and estimated the intrinsic rate of increase (r) and asymptotic density (K) for each adult population. populations at 26 degreesC had greater intrinsic rates of increase and lower asymptotic densities than populations at 22 and 24 degreesC. Populations at …
Potential Effect Of Anoplophora Glabripennis (Coleoptera: Cerambycidae) On Urban Trees In The United States, David Nowak, Judith Pasek, Ronaldo Sequeira, Daniel Crane, Victor Mastro
Potential Effect Of Anoplophora Glabripennis (Coleoptera: Cerambycidae) On Urban Trees In The United States, David Nowak, Judith Pasek, Ronaldo Sequeira, Daniel Crane, Victor Mastro

Anoplophora glabripennis Motschulsky, a wood borer native to Asia, was recently found in New York City and Chicago. In an attempt to eradicate these beetle populations, thousands of infested city trees have been removed. Field data from nine U.S. cities and national tree cover data were used to estimate the potential effects of A. glabripennis on urban resources through time. For the cities analyzed, the potential tree resources at risk to A. glabripennis attack based on host preferences, ranges from 12 to 61% of the city tree population, with an estimated value of $72 million-$2.3 billion per city. The corresponding …
