Ambulatory and aerial dispersal among specialist and generalist phytoseiid mites

Creator:: Jung, Chuleui
Abstract:: Specialist and generalist phytoseiid mites are widely used for biological control of spider mites. Understanding dispersal attributes of these mites is important to implementing more stable, cost-efficient integrated pest management. In this regard, we studied dispersal of phytoseiid mites from a local ambulatory phase of movement within a prey patch...

Biological control of spider mites by the predatory mite Neoseiulus fallacis (Acari: Phytoseiidae) in ornamental nursery systems

Creator:: Pratt, Paul D.
Abstract:: We identified and evaluated a phytoseiid predator as a biological control agent of multiple spider mites pests that occur in ornamental nurseries. When comparing species, Neoseiulus fallacis (Garman) had a wider prey range than Galendromus occidentalis (Nesbitt), a higher probability of overwintering than Neoseiulus califomicus McGregor and was equally or...

Prey-stage preference in phytoseiid mites

Creator:: Blackwood, J. Scott
Abstract:: Knowledge of how individual organisms behave in their environment can provide a greater understanding of population dynamics. In a predator-prey system, the choices made by predators when foraging for prey are important aspects of behavior. Particularly in the case of a stage-structured prey population, how the predator selects prey stages...

A review of the family Eviphididae (Acarina: Mesostigmata)

Creator:: Shoemake, Rodger Russell
Abstract:: A complete taxonomic review of the Family Eviphididae was made for the first time. The family was found to contain forty-nine species and five genera. The genera included were: Eviphis Berlese, Scarabaspis Womersley, Alliphis Halbert, Pelethiphis Berlese, and Thinoseius Halbert. The new species described were: Eviphis oregonensis from Deschutes County,...

Observations on the function and structure of the tritosternum of selected mesostigmatid mites

Creator:: Wernz, James George
Abstract:: Glyptholaspis americana (Berl.), G. confusa (Foa) and deutonymphal Parasitus sp. were studied to determine the function of the tritosternum. Studies were conducted on feeding, cleaning, temperature and humidity sensitivity using intact individuals and individuals whose tritosterna had been surgically removed. The tritosternum was found to have two functions: 1) As...

Twospotted spider mite, Tetranychus urticae Kock, in Oregon peppermint, Mentha piperita L. : sampling, population dynamics and economic injury

Creator:: Hollingsworth, Craig Stephen
Abstract:: A pest management program for Tetranychus urticae Koch in Oregon peppermint was developed based on studies of sampling, plant phenology, population dynamics and damage thresholds. A sample size of 45 leaves provided a confidence level of 90% and a confidence interval of 50%. Estimation of the sample mean was based...

Biological control of Tetranychus urticae (Koch) on peppermint by Neoseiulus fallacis (Garman) : density relationships, overwintering, habitat manipulation and pesticide effects

Creator:: Morris, Mark Alan, 1954-
Abstract:: Several aspects affecting population trends and overwintering of Neoseiulus fallacis (Garman) on peppermint were examined. Neoseiulus fallacis was the most abundant phytoseiid predator mite found in peppermint surveys throughout the western U.S. Results of pesticide exclusion and cage studies showed that N. fallacis controlled Tetranychus urticae (Koch) on peppermint in...

A review of the genus Neotrombidium leonardi, 1902, with a description of two new species, and a critical re-evaluation of the family concepts within the Trombidioidea (Acarina)

Creator:: Singer, George
Abstract:: The systematics and biology of the genus Neotrombidium Leonardi are reviewed and discussed. A generic description is presented for larvae and post-larvae of Neotrombidium, together with descriptions of two new species, N. cleronyssus and N. tenebrionyssus. The biology and life history of N. tenebrionyssus are described, with notes on rearing...
