Patterns of Host Utilization by Two Parasitoids (Hymenoptera: Braconidae) of the Eucalyptus Longhorned Borer (Coleoptera: Cerambycidae)
t a s p c w e e s e P a u a p p l t b We studied the behavior and biology of the Australian parasitoids Syngaster lepidus Brullé and Callibracon limbatus (Brullé) (Hymenoptera: Braconidae), which are being introduced into California as biological control agents of the eucalyptus longhorned borer, Phoracantha semipunctata F. (Coleoptera: Cerambycidae). Studies conducted in Australia revealed tha...
متن کاملDispersal of the Eucalyptus Longhorned Borer (Coleoptera: Cerambycidae) in Urban Landscapes
We conducted 2 markÐrecapture experiments in urban landscapes to examine the dispersal behavior of the eucalyptus longhorned borer, Phoracantha semipunctata (F.), a crepuscular beetle whose larvae bore into woody tissues of stressed or weakened eucalypts and fallen branches. Temporal changes in attractiveness of trees to beetles resulted in a correlation between beetle abundance and sampledate....
متن کاملEvaluation of Cold Temperatures and Density as Mortality Factors of the Eucalyptus Longhorned Borer (Coleoptera: Cerambycidae) in California
Environ. Entomol. 20(6): 1653-1658 (1991) ABSTRACT It was hypothesized that the northward spread of the eucalyptus longhorned borer, Phoracantha semipunctata F., in California is limited by winter temperature conditions. The cold tolerance of prepupal stages was tested by exposing infested logs to cold temperature treatments of -5, 0, +5, and + lO"C for periods of 1, 3, 7, and 30 d. Temperature...
متن کاملIsolation and molecular characterization of Cryptococcus species isolated from pigeon nests and Eucalyptus trees
Background and Purpose: Cryptococcus species are pathogenic and non-pathogenic basidiomycete yeasts that are found widely in the environment. Based on phenotypic methods, this genus has many species; however, its taxonomy is presently being re- evaluated by modern techniques. The Cryptococcus species complex includes two sibling taxa of Cryptococcus neoformans and Cryptococcus gattii. We aimed ...
متن کاملMeasuring the Sap Flow of Eucalyptus Trees
We describe the design and implementation of Savia, a sensor network system for measuring the sap flow of eucalyptus trees. Unlike prior sensor network systems, which generally take a vertically integrated approach and build everything from scratch, Savia is built out of several existing sensor systems. The difficulties we encountered when combining these systems demonstrate why a vertically in...
