Courtship, Pheromone Titre and Determination of the Male Mating Success in the Oriental Fruit Moth, Grapholita molesta (Lepidoptera: Tortricidae)"
Sequestration, into the ethyl trans-cinnamate, over control QQ hairpencils, of the behaviourally most active courtship pheromone component, in male Grapholita rnolesta (Busck 1916) results in an increased mating success attracted to ethyl cinnamate-treated dd moved significantly faster than 99 attracted to control Cfcf Since control dd that were successful at coupling on average took more attem...
متن کاملEffects of Varying Sex Pheromone Component Ratios on the Zigzagging Flight Movements of the Oriental Fruit Moth, Grapholita molesta
As the ratio of (E)-8-dodecenyl acetate (E8-12.Ac) to (Z)-8-dodecenyl acetate (28-12.A~) increased past optimal low levels in the pheromone blend, fewer males were able to fly 2 5 m upwind to the source The tracks of males that flew in plumes of such high-(E) off-blends were slower and narrower than those of males flying to lower-(E) blends. The tracks were narrower, first of all, because as th...
متن کاملManagement of insecticide resistance in Oriental fruit moth (Grapholita molesta; Lepidoptera: Tortricidae) populations from Ontario.
The development of resistance in the Oriental fruit moth, Grapholita molesta (Busck) to organophosphorus (OP) insecticides (azinphos-methyl and phosmet) is a serious threat to the tender fruit industry in Ontario (50% crop losses in 1994). Resistance to carbamate insecticides and increased survival of field-collected moths at diagnostic concentrations of pyrethroids were widespread. As a result...
متن کاملControl of the Oriental Fruit Moth, Grapholita molesta, Using Entomopathogenic Nematodes in Laboratory and Fruit Bin Assays.
The oriental fruit moth (OFM), Grapholita molesta (Busck), which is among the most important insect pests of peaches and nectarines, has developed resistance to a wide range of insecticides. We investigated the ability of the entomopathogenic nematodes (EPN) Steinernema carpocapsae (Weiser), S. feltiae (Filipjev), S. riobrave (Cabanillas et al.), and Heterorhabditis marelatus (Liu and Berry) to...
متن کاملSmall plot trials documenting effective mating disruption of oriental fruit moth by using high densities of wax-drop pheromone dispensers.
In 2004 field experiments, we compared the effectiveness of various deployment densities of 0.1-ml paraffin wax drops containing 5% pheromone versus Isomate M-Rosso "rope" dispensers for disruption of Grapholita molesta (Busck). Treatments were evaluated in 0.05-ha (12-tree) plots of 'Delicious' apples receiving regular maintenance according to growers' standards, but not sprayed with insectici...
