Incidence and control of dogwood borer (Lepidoptera: Sesiidae) and American plum borer (Lepidoptera: Pyralidae) infesting burrknots on clonal apple rootstocks in New York.
Surveys were conducted in the major apple growing regions of New York state to determine the incidence of borers infesting burrknots on clonal apple rootstocks. Dogwood borer, Synanthedon scitula (Harris), was generally prevalent throughout the state, but American plum borer, Euzophera semifuneralis (Walker), was limited to western New York apple orchards near infested stone fruit trees. Insect...
متن کاملEvaluation of thiamethoxam and imidacloprid as seed treatments to control European corn borer and Indianmeal moth (Lepidoptera: Pyralidae) larvae.
Efficacy of thiamethoxam (Cruiser) and imidacloprid (Gaucho) were evaluated as seed treatments for controlling European corn borer, Ostrinia nubilalis (Hübner) and Indianmeal moth, Plodia interpunctella (Hübner) larvae in stored grain. At approximately 22-26 degrees C, all fifth instar European corn borers died after two or 4 d of exposure to corn treated with 250 and 500 ppm thiamethoxam, resp...
متن کاملMultiacreage evaluation of aerially applied adherent malathion granules for selective insect control and indirect reduction of mycotoxigenic fungi in specialty corn.
Aerially applied adherent corn flour granules containing 1% malathion were more often as, or more, effective than 15% chlorpyrifos (Lorsban 15G) granules in controlling caterpillars and sap beetles in high amylose corn in 1997 than 1996. Use of malathion granules corresponding closely in size to chlorpyrifos granules in the second year of the study apparently increased relative efficacy. Signif...
متن کاملDistribution of European Corn Borer (Lepidoptera: Pyralidae) Egg Masses and Larvae on Sweet Corn in New York
Environ. Entomol. 15: 501-506 (1986) ABSTRACT Studies were conducted in commercial sweet corn fields in upstate New York to collect information for developing a sampling protocol for egg masses and larvae of European corn borer (ECB), Ostrinia nubilalis (Hubner). Information was collected on 1) aggregation of populations in portions of the field (e.g., aggregation along borders), 2) distributio...
متن کاملPest status of American plum borer (Lepidoptera: Pyralidae) and fruit tree borer control with synthetic insecticides and entomopathogenic nematodes in New York State.
Surveys were conducted in 1994 and 1995 to determine the pest status of the American plum borer, Euzophera semifuneralis (Walker), in New York State stone fruit crops. These surveys indicate that American plum borer is the most important of the wood-boring insects infesting tart cherries and also is an important pest in peaches suffering from canker diseases. It is not prevalent in plums or in ...
