Forest ant composition, relative abundances, and foraging following aerial spraying of carbaryl to suppress Western Spruce budworm

Creator:: Murphy, Christopher F.
Abstract:: An outbreak of western spruce budworm Choristoneura occidentalis in the Blue Mountains of eastern Oregon in 1983 was treated with helicopter applied carbaryl. Effects of the spraying on forest ants were determined from pre- and postspray samples taken from two carbaryl sprayed and two unsprayed plots. In each 0.75-ha plot,...

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...

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...

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%),...

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...

The SELCTV database : the susceptibility of arthropod natural enemies to agricultural pests to pesticides

Creator:: Theiling, Karen M.
Abstract:: Documentation of the side effects of pesticides on arthropod natural enemies has expanded rapidly since the 1950's as part of an increase in non-target side effects literature. Most reviews have been based on empirical analysis of selected literature. The SELCTV database was developed to make a larger information base accessible...

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...
