Significant Survival

AbstractDevelopment of resistance to organophosphorus and carbamate insecticides by the Oriental fruit moth, Grapholita molesta (Busck), has caused great concern regarding the sustainability of peach production in Ontario, Canada. Thus, a resistance management program was implemented and a procedure was developed to monitor for resistance to insecticides in adult moths. Diagnostic concentrations needed to distinguish susceptible genotypes from resistant individuals were determined to be carbofuran (0.1 μg per vial), carbaryl (1.0 μg per vial), malathion (0.5 μg per vial), and cypermethrin (2.5 μg per vial). Significant survival of field-collected moths to diagnostic concentrations of cypermethrin suggested that resistance to pyrethroids might be widespread. The seasonal patterns of resistance of several Oriental fruit moth populations from the Niagara Peninsula of Ontario indicated a decrease in frequencies of resistance to all insecticides tested from 1996 through 1998. Resistance levels were unstable, thus suggesting that resistance could be successfully managed. Our data confirmed the usefulness of the vial test to monitor for resistance to insecticides in the adult Oriental fruit moth, and provided the basis for the development of a resistance management strategy designed to extend the efficacy of all classes of insecticides used for control.

Abstract G. molesta is a serious pest of economic importance of commercial stone and pome fruits around the world. G. molesta damages peaches, nectarines, plums, cherries, apricots, apples, pears, quinces and nashi (Asian pears) and can also attack and cause economic damage on other commercial fruits. In severe attacks, young trees can suffer distortion of growing shoots and stems, which makes pruning, training and shaping the tree canopy difficult, particularly for close-planting industrial systems such as Tatura trellis. One larva can damage many shoots by tunnelling deep into young shoot tips. Larvae move to feed on the green fruits usually after shoots mature and harden. One larva can damage many fruits, particularly when fruits are located close to each other.

Important Pest

Oriental fruit moth, Grapholita molesta (Busck) (Lepidoptera: Tortricidae), is an important pest of stone and pome fruits. Growers usually depend on chemical insecticides to control this pest, but demand for more environmentally-friendly means of controlling pests is increasing. At least 77 plant extracts have been reported to be effective against other lepidopterans, but their acute toxicity against G. molesta has rarely been studied. Among these 77 materials, we assessed the residual toxicity of 32 extracts against first instar larvae (
