Responses of males to a pheromone blend of female Oriental fruit moth with and without E8, E10-dodecadien-1-ol, a pheromone component of codling moth (Lepidoptera: Tortricidae)

Creator:: Allred, Darin B.
Abstract:: E8,E10-dodecadien-1-ol, the primary component of the female sex pheromone of codling moth, Cydia pomonella L., has no attraction to male Oriental fruit moth (OFM), C. molesta (Busck). However, this compound when added to the OFM pheromone blend of Z8-dodecenyl acetate (85.5%), E8-dodecenyl acetate (5.5%), and Z8- dodecen -1 -ol (9.0%),...

Within and between plant dispersal and distributions of adult females and immatures of Neoseiulus californicus and N. fallacis (Acari: Phytoseiidae) in bean and apple plant systems

Creator:: Pratt, Paul D. (Paul David), 1970-
Abstract:: Intra- and interplant movement and dispersal of the predator mites Neoseiulus californicus (McGregor) and Neoseiulus fallacis (Garman) were studied on both lima bean (Phaseolus lunatus L.) and apple (Malus pumila Miller) branch plant systems that were seeded with excess numbers of the spider mite Tetranychus urticae Koch. Individuals of either...

Spatial patterns of predaceous and phytophagous apple mites (Acari : Eriophyidae, phytoseiidae, Stigmaeidae, Tetranychidae) : intra- and interspecific relationships

Creator:: Slone, Daniel H.
Abstract:: Aggregation and species association of 9 species of phytophagous and predaceous mites were studied for 6 yr in an orchard with 100, 2 m tall 'Red Delicious' apple trees. To quantify aggregation, a method was developed that is powerful, and easily interpreted. It relates the proportion of habitat occupied to...

AppleMgr, a prototype decision aid for apple pest management

Creator:: Haley, Sue
Abstract:: Computer decision aids can help integrate and apply diverse sources of information and expertise to problems of integrated pest management (IPM) in agriculture and forestry. AppleMgr combines a rule-based expert system with databases and spreadsheets in a prototype decision aid intended to be expanded and modified for use by extension...

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...

Chemotherapeutic and nontarget side-effects of benomyl to the orange tortrix (Argyrotaenia citrana) and the braconid endoparasite Apanteles aristotelia

Creator:: Sewall, David K.
Abstract:: Benomyl, a systemic benzimidazole fungicide was incorporated into artificial diet and evaluated for its oral toxicity to nonparasitized and parasitized third instar orange tortrix larvae, Argyrotaeniae citrana (Fernald) and its food chain toxicity via the host to the solitary braconid endoparasite Apanteles aristoteliae Vierek. Concentrations of benomyl ≤ 300 ppm...

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...
