Resource Type:: Conference Proceeding
Full Text:: controlling codling moth fromOregonuntil 1989. However, in a study conducted byMoffitt etal during 1986 to

Oviposition of the codling moth, Laspeyresia pomonella (L.), on several varieties of apples and pears

Creator:: Gut, Larry J.
Abstract:: Ovipositional behavior of the codling moth, Laspeyresia pomonella (L.), on several varieties of apples and pears grown in the Pacific Northwest was investigated during the spring/summer of 1979. Field studies showed that early in the season more eggs were laid on the Bosc variety than on several other apple and...

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%),...

Integration of microbial and chemical controls against codling moth, Cydia pomonella (L.) : laboratory and field evaluation

Creator:: Bajwa, Waheed Ibrahim
Abstract:: The feasibility of managing codling moth, Cydia pomonella (L.), with mixtures of Bacillus thuringiensis-based microbial and selected chemical insecticides was studied under laboratory and field conditions. Joint actions (synergism, additivity and antagonism) of these mixtures were determined for both egg and larval stages. Higher rates of microbial control agents (MCAs),...

Detection and characterization of resistance to pesticides in codling moth, Cydia pomonella L. from Oregon

Creator:: Arshad, Muhammad, 1958-
Abstract:: Toxicological studies were carried out to evaluate the susceptibility of codling moth, Cydia pomonella L. to different insecticides. Bioassay procedures for adults and larvae were standardized in terms of posttreatment holding and temperature, age and sex of insects, insecticide formulations and selection of a reference strain. This study detected a...

Host selection, reproductive biology, host-specific development and mortality of the codling moth, Cydia pomonella (L.) (Lepidoptera: Torticidae), in apple and pear

Creator:: Marti, Santiago Marti
Abstract:: The biology and behavior of the codling moth, Cydia pomonella (L.), was studied to determine factors responsible for differences in susceptibility to moth damage among apple and pear cultivars. In release experiments, codling moth adults were intercepted in significantly greater numbers in host (apple, pear) than in non-host (maple) trees,...

Assessing the safety of weed biological control : a case study of the cinnabar moth Tyria jacobaeae

Creator:: Fuller, Jason L.
Abstract:: The cinnabar moth, Tyria jacobaeae (L.) (Lepidoptera:Arctiidae), was released in 1959 to control the grassland weed tansy ragwort, Senecio jacobaea L. (Asteraceae), despite evidence that caterpillars of this species can feed on native plants within the genera Senecio and Packera. Previous studies confirmed the moth's ability to develop on the...

Seasonality of codling moth, Cydia pomonella L. (Lepidoptera: Olethreutidae) in the Willamette Valley of Oregon : role of photoperiod and temperature

Creator:: Setyobudi, Lilik
Abstract:: The seasonality, relationship of temperature and photoperiod to growth and post-diapause development, and overwintering behavior of codling moth, Cydia pomonella L., (Lepidoptera: Olethreutidae) were studied over a three year (1986-1989) period. The developmental threshold varied from a low of 9.66°C for the second instar to a high of 14.23°C for...

Environmental controls on the capacity of tansy ragwort (Senecio jacobaea L.) to compensate for defoliation by cinnabar moth (Tyria jacobaeae L.)

Creator:: Cox, Caroline Shipley
Abstract:: To assess the effect of summer moisture stress on the capacity of tansy ragwort (Senecio jacobaea L.) to compensate for defoliation by the cinnabar moth (Tyria jacobaeae LT7), the performance of plants grown under different irrigation regimes was measured. The proportion of plants producing new leaves following defoliation, the number...
