CONTROL OF CODLING MOTH ON WALNUTS WITH A GRANULOSIS VIRUS ABSTRACT P. V. Vail
A granulosis virus was tested as a potential control agent for codling moth larvae on walnuts. The virus was produced and supplied by Sandoz, Inc. as our experimental insecticide. This virus is of considerable interest because it has little or no effect on beneficial parasites and predators and, therefore, probably would not disturb the control of the walnut aphid by the parasite Trioxys palladus.
متن کاملI. Why Puffers Work: Determining the Effects of Residual Releases on Control of Codling Moth Ii. Optimizing “meso-pheromone” Emitters for Codling Moth Management in Walnuts
Our results suggest that the level of pheromone applied per “puff” by the aerosol “puffer” dispenser can be reduced dramatically without any detectable change in the size or shape of the pheromone plume. Reductions by 50% in the active ingredient per puff did not result in any increased trap capture of sterile codling moths downwind of the puffer unit. A substantial, but smaller and narrower, p...
متن کاملRefinement of the Pete Model for Prediction of Codling Moth Phenology in Walnuts
A preliminary conclusion of the research is that there does not appear to be significant genetic differences in developmental times between the codling moth populations in walnuts and apples. Codling moths were collected from walnuts and placed onto artificial diet as a rearing medium. Data obtained from these individuals were consistent with the data obtained from colonies of codling moth coll...
متن کاملAnalysis of the Survival and Reproduction of the Codling Moth in Harvested Walnuts
Previous studies supported by the Walnut Board had shown that survival of codling moth (CM) larvae is proportional to their age at the time of harvest and that overall survival is poor compared to siblings reared on artificial diets. In 1986 considerably more data were collected on the infestation levels of codling moth in different varieties of walnuts. In addition, the population structure at...
متن کاملClassical Biological Control of Codling Moth: the California Experience
Codling moth is a notorious fruit-boring pest that has extended its original distribution from the natural apple forests of Central Asia to cover all apple growing regions of the world. Having been discovered in California as early as 1872, codling moth has continued to be the dominant pest of apple, pear and walnut production causing extensive damage in the absence of insecticide treatment. In...
