Improved Population Monitoring of Bark Beetles and Predators by Incorporating Disparate Behavioral Responses to Semiochemicals
TLDR
Variation between herbivores and their natural enemies in their phenology, preferred pheromone blends, and infested host material should be considered when developing estimates of relative pest and predator densities for subsequent management options. Expand
Relationships between bark beetles and their natural enemies.
UC scientists apply IPM techniques to new eucalyptus pests
TLDR
Scientists are developing new strategies to control the recent invaders in concert with existing pest management programs, integrating methods across broad geographic, horticultural and economic scales. Expand
The biology of Psyllaephagus bliteus Riek (Hymenoptera: Encyrtidae), a parasitoid of the red gum lerp psyllid (Hemiptera: Psylloidea)
TLDR
Observations of host-handling behavior suggest that the large lerps of fifth instar psyllids increase host- handling time, thereby impeding oviposition and providing some protection from parasitism. Expand
Prevalence, Habitat Selection, and Biology of Protocalliphora (Diptera: Calliphoridae) Found in Nests of Mountain and Chestnut-backed Chickadees in California
TLDR
Larger nests apparently provided the larvae with refuges from probing activities of adult chickadees, allowing maximum survival in these nests, and Nest odor probably aids Protocalliphora females in nest location, but other short-range stimuli apparently determine which hosts are acceptable for oviposition. Expand
Effects of parasitic flies (Protocalliphora spp.) on nestlings of mountain and chestnut-backed chickadees
TLDR
Plus de 90% des nids de Parus ganubeli et de P. rufescens sont infestes dans une zone cotiere en Californie, affirmant que la mortalite des jeunes dues a cette cause est faible. Expand
Urban Forests and Insect EcologyComplex interactions among trees, insects, and people
TLDR
Research on human influences on the ecology of urban forest insects is reviewed and changes in plant diversity, introducing exotic species, polluting the environment, and placing trees under stress are reviewed. Expand
Exploiting Behavioral Disparities Among Predators and Prey to Selectively Remove Pests: Maximizing the Ratio of Bark Beetles to Predators Removed During Semiochemically Based Trap-Out
TLDR
Lures that contain enantiomers of ipsdienol most preferred by I. pini, in combination with lanierone, can selectively remove up to three to six times more pests than predators during the spring, and delaying deployment of the same lures until summer can result in removal of up to 39 times more pest than predators. Expand
Biological control of the blue gum psyllid proves economically beneficial
In 1992 a parasitoid native to Australia was introduced into California in a biological control program directed against the blue gum psyllid from Australia. Interviews with baby blue gum eucalyptus… Expand
Intraguild interactions between generalist predators and an introduced parasitoid of Glycaspis brimblecombei (Homoptera: Psylloidea)
TLDR
It is indicated that predation risk of parasitized hosts varies depending on the developmental stages of the psyllids, and the current study indicated that predatory interference on the introduced parasitoid increased the parasitoids mortality relative to the mortality observed in the Parasitoid-alone treatment.
