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 کاملAntioxidant Potential of Naringenin Helps to Protect Liver Tissue from Streptozotocin-Induced Damage
Background: Naringenin is a bioactive flavonoid found in grapes and citrus fruits including tangelo, blood orange, lemons, and tangerines. The aims of this study were to investigate the ability of naringenin to scavenge free radicals and determine its ability to protect animals from streptozotocin (STZ) -induced liver damage. Methods: The free radical-scavenging activity of naringenin was ev...
متن کاملN-WASP helps cancer cells open up
HIV’s kinesin chauffeur G audin et al. identify a type of kinesin that ferries HIV to the plasma membrane, helping the virus escape from macrophages. HIV reproduces inside T cells, killing them in the process. But the virus can also replicate in macrophages, which survive infection and serve as reservoirs of HIV. In T lymphocytes, new viral particles are born at the plasma membrane, but in macr...
