“…One of the major decisions growers must continually make in good pest management programs is the timing of insecticide treatments. Since the identification of the codling moth sex-attractants either as live virgin females (BUTT and HATHAWAY, 1966) or synthetic pheromone (ROELOFS et a]., 1971), the sex-pheromone traps have offered a method for studying codling moth flight activity and for timing insecticidal sprays (BATISTE et al, 1970;MADSEN andVAKENTI, 1972, 1973;ROCK et al, 1978;AHMAD and AL-GHARBAWI, 1986). By using trapping data alone, treatments were usually recommended 'at or near' the peak of codling moth flight in any given generation.…”

Successful spraying against Cjdiia pomonelki (L.), the main pome fruits pest in Iraq orchards, depends on correct timing, which was determined by the degree-days model or at intervals of 100 k 10 degree-days after the biofix.Sprays are most effective against the newly hatched larvae before entry into the fruits. The optimum timing with laresban treatments was determined to be at 200 degree-days after the biofix or after an average degree-days accumulation of 195 DD (SD = 59) and 298 DD (SD = 67) when daily degree-days calculated by the method of the sine-wave. ~~ ; , 1973: Codling moth: Use of codlemonebaited traps

“…Biofix is the date of the first sustained capture of three to five adult male moths, marking the start of the phonological model for the growing season (Glenn 1922). Treatment periods are based on estimations of important life stages based on trap captures and DD (Rock, Childers and Kirk 1978). Aligning spray intervals to specific developmental periods can significantly reduce the number of sprays needed (Rock, Childers and Kirk 1978).…”

Aligning spray intervals to specific developmental periods can significantly reduce the number of sprays needed (Rock, Childers and Kirk 1978). Emergence of the codling moth larvae from eggs is the most important threshold for determining spray application timing for this pest (Arthurs, Lacey and Miliczy 2007).…”

Specialist iv ABSTRACT Assessment of Granulovirus, Spinosad, and Mating Disruption for Controlling Cydia pomonella L. [Lepidoptera: Tortricidae] in Organic Coastal California Apple Orchards Raven Marie Lukehart Codling moth, Cydia pomonella [Lepidoptera: Tortricidae], is a major entomological pest of apples, pears, and walnuts cross the world (Pajac et al. 2016).Female codling moths lay eggs on the apple exocarp and larvae burrow within the fruit causing economic losses to fruit growers. Organic apple orchards in San Luis Obispo, CA currently have three codling moth, Cydia pomonella, control options commercially available including granulovirus (CpVG), spinosad, and mating disruption. In field tests on apple (Malus), we compare percent fruit injury between treatments of granulovirus (2.43 oz/ha Cyd-X® organically approved, Certis USA, Columbia MD), spinosad (4.05 oz/ha Entrust® Naturalyte® organically approved WP formation, Dow AgroSciences, Indianapolis IN), and a control. We also compared mating disruption in form of codling moth Codlemone® sex pheromone (257 ties/ha (506 mg)/acre Isomate®-OFM TT organically approved Pacific Biocontrol Corporation Vancouver, WA) against a control. Delta taps and 1 mg pheromone lures were used to trap males and track the degree day (DD) model for the two orchard's codling moth populations to determine application timing for each treatment. A preliminary DD model was used based on the University of California at Davis Agricultural Extension codling moth DD model.During 2016 trials no detectible control was provided by spray treatments with an average fruit injury of 26% control, 23% granulovirus, 28% spinosad. During 2016 trials no detectible control was provided by mating disruption with an average fruit injury of 16% control and 16% pheromone. During 2017 trials there was detectible control provided by the treatments to the crop by both spray treatments and pheromone ties. 2017 average fruit injury for spray treatments was 51% control, 20% granulovirus, and 14% spinosad. 2017 average fruit injury for mating disruption was 29% control and 6% pheromone. Data suggest underlying relationship between location specific climate factors, cultivars, codling moth populations, and treatment efficacy.Thank you and good wishes to all that made this project possible, especially my graduate chair and friend, David H. Headrick for volunteering his time to counsel me. I would also like to thank my farm crew, interns, and husband for assisting me in executing the project. Thank you to my family for your patience and support during my studies.
