Biology and use of the whitefly parasitoid Encarsia formosa.
The biology of adult and immature E. formosa is reviewed, population dynamics of whitefly-parasitoid interactions, and commercial use in greenhouses are reviewed. Expand
Relative Toxicity of Abamectin to the Predatory Mite Phytoseiulus persimilis (Acari: Phytoseiidae) and Twospotted Spider Mite (Acari: Tetranychidae)
Abamectin at selective sublethal concentrations (i.e., 1-4 ppm) could be of value in adjusting predator /prey ratios in integrated management of spider mites. Expand
Synthesis and validation of a degree-day model for navel orangeworm (Lepidoptera: Pyralidae) development in California almond orchards
The degree-day information adequately forecasts the onset of the second-generation moth flight period in six of the seven data sets, and consistently less than that for females. Expand
Designing an effective trap cropping strategy: the effects of attraction, retention and plant spatial distribution
1.Trap cropping, the use of alternative host plants to reduce pest damage to a focal cash crop or other managed plant population, can be a sustainable strategy for pest control, but in practice itExpand
Oviposition behavior of the biological control agent Aphidoletes aphidimyza (Diptera: Cecidomyiidae) in environments with multiple pest aphid species (Hemiptera: Aphididae)
Investigation of the oviposition behavior of the aphidophagous midge Aphidoletes aphidimyza when faced with multiple prey choices suggests that perceived quality of an aphid patch as an Oviposition site is influenced more by density and location of the Aphid patch on the plant than by the species of aphid within the patch.

Influence of fat intake and caloric restriction on bone in aging male rats.
Higher dietary fat content did not affect BW in CR animals, but did result in lower distal femur BMC, which was entirely accounted for by reduction in BW. Expand
Compatibility of Insect Growth Regulators with Eretmocerus eremicus (Hymenoptera: Aphelinidae) for Whitefly (Homoptera: Aleyrodidae) Control on Poinsettias: I. Laboratory Assays
The compatibility of five insect growth regulators, buprofezin, pyriproxyfen, fenoxycarb, pymetrozine, and kinoprene, were tested in the laboratory for compatibility with the whitefly parasitoid Eretmocerus eremicus Rose and Zolnerowich to determine survivorship and toxicity of B. argentifolii nymphs. Expand
Pathogenicity of conidia-based preparations of entomopathogenic fungi against the greenhouse pest aphids Myzus persicae, Aphis gossypii, and Aulacorthum solani (Hemiptera: Aphididae).
Tests showed that adult aphids are more susceptible than nymphs to fungal infection but confirmed that infection has a limited pre-mortem effect on aphid reproduction, and the potential of fungal pathogens as aphid-control agents is discussed. Expand
Assessment of Cost and Performance of Eretmocerus Eremicus (Hymenoptera: Aphelinidae) for Whitefly (Homoptera: Aleyrodidae) Control in Commercial Poinsettia Crops
This study is the first to demonstrate the ability of E. eremicus releases to suppress whitefly populations in commercial poinsettia crops and parasitism of T. vaporariorum in this trial, and cost of biological control was 27 fold more expensive than chemical control. Expand
Greenhouse Trials of Aphidius Colemani (Hymenoptera: Braconidae) Banker Plants for Control of Aphids (Hemiptera: Aphididae) in Greenhouse Spring Floral Crops
Abstract Banker plants with Aphidius colemani Viereck were tested in greenhouses in Massachusetts and New York for control of cotton aphid Aphis gossypii Glover, and green peach aphid Myzus persicaeExpand
